imToken Progress | NFT summer and EIP 1559 support

EIP-1559 On August 5, Ethereum’s highly anticipated London upgrade went live and introduced EIP-1559. imToken supports this hard fork, so users don’t need to do anything for it. You can still use the current version of imToken and send transactions as usual. On the day of the upgrade, imToken TV host Gerry and Head of Product Ashu gave a commentary on the London upgrade on Bilibili, a Chinese video sharing website, discussing the impact of EIP-1559 on miners, users and wallet development companies. Commentary on the London Upgrade  It has been a month since the London upgrade, and as of writing, 212,000 ETH have been burned, with an average of 4.63 ETH burned every minute. In addition to the burned ETH, what other impact has EIP-1559 brought to Ethereum? In the video How to observe the changes brought by EIP-1559, Yuan, the product manager of imToken, talked about how he got some insights through Etherscan, the Ethereum browser. P.S. If you're not quite sure what EIP-1559 is all about, please check out this blog👇 Ethereum's London hard fork: What is EIP-1559?   Community Events Adventurer's Guide to Crypto Ethereum’s gas fees boosted during the DeFi summer of 2020, and the fees go up again since crypto enters a NFT summer of 2021. According to Ultrasound Money, OpenSea NFT marketplace has burned over 30,000 ETH, ranking first in the burn leaderboard. So, have you ever thought of minting your own artwork into a NFT? On August 10, imToken and StaFi jointly launched an event: Adventurer's Guide to Crypto. Users can submit their artworks such as short videos and electronic music to us. Finalists’ entries will not only become part of the art exhibition The Art Space gallery (in Shanghai), but also be minted into NFT under our guidance. NFT Artworks Call for Entries | Crypto World Adventure Guide As of now, we have received 60+ entries and will announce the finalists on September 6.   How does YGG help players earn income? Axie Infinity, the new leader in NFT gaming, is also at the top of the burn leaderboard published by Ultrasound Money. It has burned over 7,000 ETH. It is worth noting that Axie Infinity's boom in popularity was fueled by Yield Guild Games (YGG), a play-to-earn gaming guild. On August 12, imToken invited Gabby Dizon, co-founder and CEO of YGG, to discuss: What's the key point of the play-to-earn business model? Will this model disrupt the way we work and live in the future? Will YGG build a branch in China to expand its reach? ...... Missed the AMA? Well, don’t worry, we've written up AMA | YGG & imToken Fans    Security What do you think is the most important factor in wallet security? Backing up mnemonics? Writing down passwords? Or keeping a low profile? No, the most important factor is to make sure the App you downloaded, whether a crypto exchange or a self-custodial wallet, is not fake, otherwise you're putting money in the pockets of scammers at the very beginning. How to take the first step towards asset security? Please read these blogs below for detailed information. How to download imToken safely? imToken on security: How to tell if a website or an App is not fake? Wallet security letter #3: Crypto wallet scams: Fake Apps, texts and Mnemonics   Next imToken is expected to support users to customize maxPriorityFee (tip paid to miners) and maxFee (maximum fee) introduced by EIP-1559 in the next version, namely, v2.9.6.

Announcement: Removing DApp List Feature in iOS Version

Announcement: Removing DApp List Feature in iOS Version

We regret to announce that we have to remove the list of featured DApps for iOS users in the next update (imToken 2.9.6) due to Apple App Store guidelines. But iOS users are still able to use the DApp browsers in imToken by entering any URL into the search bar. We will continue to update the new versions and improve services for our iOS users.   Key Takeaway Your assets in the DApp and imToken are safe and secure (We are not able to change any of your assets, either in the wallet or in the DApp) If you have ever marked your favorite DApp in imToken, those favorite DApps will still be available Android users will not be affected by this change and can still use it as usual.    Why we remove the DApp Browser list on iOS Due to Apple's App Store Review Guidelines’ latest rule that "should not attempt to extend or expose native platform APIs to third-party software”,  all iOS apps must meet Apple's App Store review guidelines before being listed on Apple's App Store. In order to allow iOS users of imToken to keep using any features besides the DApp Browser, we have to remove the DApp Browser list for the iOS version of imToken in the next version release (imToken 2.9.6).   Is the iOS version of imToken completely unusable for DApps? "No." iOS users can still use DApp browsers.  From imToken 2.9.6 on, the DApp Browser function is still available, and iOS users can use any DApp by entering the URL into the search bar. We also keep the DApp collection section, so that the DApps that have been collected can still be used as usual. Any assets in your DApps are safe and secure. As a non-custodial wallet, imToken cannot alter any of the user's assets. For users who wish to continue using the relevant DApps in imToken, you can also use WalletConnect on your laptop or computer to connect to a DApp with imToken via QR code.   Recommendation We always welcome developers to integrate imToken's SDK, develop DApps, and integrate Wallet Connect to make it easier for users to connect to imToken on their PCs.

imToken on security: How to tell if a website or an App is not fake?

imToken on security: How to tell if a website or an App is not fake?

You might have read our recent series on crypto scams - for example part 3 on fake apps.  Today our security team prepared a tutorial on how to spot fake websites and apps. Read on to learn more.   Stay safe in app stores When downloading an app like imToken, you might go to the Google Play Store or Apple App Store. When visiting one of those two app store, simple tips can help you to stay safe: Search for the app name and be careful if you find multiple apps, because usually only one is real and fake apps try to look similar to real ones An app with many reviews and downloads is less likely to be fake, because fake apps will be taken offline before getting many downloads If you don’t download from the two big app stores, be careful, because smaller app stores are - generally speaking - less safe. Why? Because in our security team’s experience, they are less strict in taking down fake apps. If you don’t download from app stores at all, you might use an official website - such as imToken’s https://token.im/ . In this case, here are our recommendations:   Three steps to tell if a website is real and safe Make sure that the domain name you entered in the browser is: https://token.im/Note: Be sure to use HTTPS instead of HTTP. Make sure there is a security icon such as 🔒 or 🛡 in front of the domain name. Click the security icon, the website is real and safe if the pop-up shows “Connection is secure”. Otherwise, the website is fake and you can contact us via support@token.im. We’ll get you the help you need. Before downloading imToken, please make sure you have completed the three steps.    How can I verify the authenticity of an imToken APK file I downloaded? If you downloaded an imToken APK file through a third-party website or a friend, please check the authenticity of the APK by checking its hash before installing it.  The SHA-256 of a file is a kind of digital fingerprint which ensures that data is not modified or tampered with. The simplest way is to get the SHA256 through online tools. Move the APK file to desktop Open the website: https://emn178.github.io/online-tools/sha256_checksum.html Click “Drop File Here” and upload your APK file to get the result Compare the SHA256 of the APK file with that of different versions of imToken listed in the table below. If the result is identical to the SHA256 in the table, it can be said that your APK file is original and safe.If you encounter any problems during the process, please feel free to contact us via support@token.im   Mac users Move the APK file to desktop Open Terminal (default path: Launchpad - Other - Terminal) and enter cd desktop/ Enter shasum -a 256 + the name of the file, and press “Enter” to get the SHA256 of the file. Compare the SHA256 of the APK file with that of different versions of imToken listed in the table below. If the result is identical to the SHA256 in the table, it can be said that your APK file is original and safe.If you encounter any problems during the process, please feel free to contact us via support@token.im Windows users Move the APK file to desktop Open the command line tool(press Win and R, enter CMD, press Enter) and enter cd desktop/, press Enter Enter certUtil -hashfile + the name of the file + SHA256, and press “Enter” to get the SHA256 of the file. Compare the SHA256 of the APK file with that of different versions of imToken listed in the table below. If the result is identical to the SHA256 in the table, it can be said that your APK file is original and safe.If you encounter any problems during the process, please feel free to contact us via support@token.im

Wallet security letter #3: Crypto wallet scams: Fake Apps, texts and Mnemonics

Wallet security letter #3: Crypto wallet scams: Fake Apps, texts and Mnemonics

Stay alert! In part 3 of our series, we explore more scams: Fake wallets, scam text messages and more. Let’s learn from others and stay safe out there! If you have any questions, our support team is always here to help.   Fake wallet scam In imToken Wallet Security Newsletter #1, we disclosed that scammers had purchased search terms and Ad space on Baidu. When users searched for imToken, the results would show scam sites where fake wallet Apps would be downloaded. This time we look at another channel, found by our users. The scammers contacted Feixiaohao, a small Chinese app store, disguised as imToken officials and replaced the official website URL on Feixiaohao with a fake one.  imToken security team found out about that and immediately contacted Feixiaohao to take down the fake URL, while continuously collecting evidence to help the police block these fake websites and arrest the scammers. ⚠️Warning: Scammers replaced the imToken download link on Feixiaohao with a fake URL between May 16 and August 8, 2021. Users who have downloaded imToken via Feixiaohao during this period are at risk of losing their assets. What should you do if you have downloaded a fake App? Addresses created via fake Apps or addresses that have been imported into fake Apps are at risk. Stop using these risky addresses ASAP Download imToken from our official website: https://token.im and create a new wallet address Transfer assets from the fake App to the new wallet address ASAP So, what is the most important factor in wallet security? My answer is to bookmark imToken's official website address https://token.im. If you download imToken from the Apple App Store, Please confirm that the developer of imToken is IMTOKEN PTE.LTD., and all others are fake Apps. Likewise, when you use other wallets such as MathWallet, TokenPocket or MetaMask, please make sure to download them from official websites or Google Play and Apple app stores.   SMS Scam Recently, some users received SMS claiming that their imToken accounts were suspected of black money trading, and they needed to click a URL for verification, otherwise their funds would be frozen. If you click the link in the SMS, you will be taken to a fake AML/imToken website which will lure you to download a fake imToken App resulting in asset loss. Please note that imToken does not collect users’ personal information. The imToken security team believes that scammers obtain information through social engineering and then send SMS to users pretending to be imToken officials to commit fraud. ⚠️Note imToken is a self-custodial wallet, so it is impossible for us to freeze your assets. It is strongly suggested to bookmark our official website: https://token.im After downloading the genuine imToken, the next step is to correctly back up the mnemonic, as mnemonic leak can result in a loss of assets. So what happens if someone intentionally makes their mnemonic public?   Mnemonic Scam ”I'm liquidated. I have enough of this and I wanna quit crypto. This is my mnemonic, and there are still some UNI in my wallet, just take it as you like. “ Is there a free lunch? No! There is no such thing as a free lunch. It’s a mnemonic scam! The scammer claimed that he wanted to quit the crypto because he got liquidated, he made his mnemonic(12 English words) public, and wanted to give away the tokens in his wallet. After importing the mnemonic into the wallet, you’d find that the address does have some tokens such as UNI but no ETH. So if you want to transfer UNI to your own wallet, you need to transfer ETH to the scammer’s address first to pay the miner fees. However, once you transfer ETH into that wallet, your ETH will be stolen immediately. Mnemonic Scam ⚠️Warning: There is no such thing as a free lunch! Is the safety of your assets assured once you have properly backed up your mnemonic? No.  You also have to be wary of authorization scams.   Authorization Scam Recently, scammers have been airdropping UniH to RUNE holders. If you receive UniH and authorize a DApp such as Uniswap to manage the token on your behalf, then the scammer will exploit vulnerabilities in the RUNE contract to carry out attacks and steal RUNE from your wallet. ⚠️ Note: imToken has marked UniH as a risky token. Be wary of airdrop tokens and do not approve it for swapping.   End  In July, 12 tokens, 50 DApps and 130 addresses were marked by the imToken security team as risky. If you recognize any risky DApps or tokens, please report to us via support@token.im to help more users avoid being deceived.

Ethereum’s London hard fork: What is EIP-1559

Ethereum’s London hard fork: What is EIP-1559

We briefly introduced the five changes in Ethereum upgrades (Ethereum’s London Upgrade: imToken Support and Need to Knows ). In this article, we will focus on the one of change, also the most anticipated change, EIP-1559. About EIP-1559  EIP-1559 will change Ethereum's fee market, because it introduces a “base fee” for adding transactions to the network. The base fee will change the gas fee automatically based on market demand, which helps wallets and users to estimate transaction fees more easily.  EIP-1559 also adds a new transaction type where users can specify the maximum fee they are willing to pay and the max priority fee they are willing to pay for miners. The difference between the maximum fee, base fee and miner tip will be returned to users.  EIP-1558 will burn the base fee for slowing down the inflation of ETH partly, so part of the community take it as a good way to improve the Ethereum network’s economics.  How imToken supports EIP-1559 After the Ethereum’s London hard fork, we already support gas fee estimation based on the rules of EIP-1559 in imToken. The new transaction type about “maxPriorityFee” and “maxFee” in EIP-1559 is expected to be released soon, with imToken 2.9.6. We are not able to predict the change of transaction fee for now, but we keep tracking the development of EIP-1559. Design Goals of EIP-1559  Better User Experience  Ethereum and Bitcoin currently both use a first price auction mechanism. This fee mechanism is simple but inefficient. The biggest problem is cost estimation. EIP-1559 attempts to solve this problem by making all transactions pay the same fee as possible. In most cases, the user only needs to decide whether to initiate a transaction, without having to consider how to set the fee. Slack mechanism Block space utilization often changes. While some blocks are almost empty others are full of transactions. The variable block size will vary with actual demand and improve speed slightly. Better security  When - in the future - block rewards disappear, transaction fees alone will not be enough to motivate miners to maintain network security. By destroying transaction fees, EIP-1559 can extend the time for block rewards to incentivize miners without increasing the total supply, thereby ensuring the security of the network. Prevent Economic Abstraction In simple terms, only ETH is allowed to pay transaction fees. If users can use any token to pay transaction fees, it may threaten the reserve status of ETH. EIP-1559 alleviates this problem by forcing ETH as a fee token. How EIP-1559 works The old gas fee mechanism Miner fee = GasPrice * GasUsed GasUsed (gas): The total amount of gas consumed by the transaction GasPrice (gwei): The price per unit of gas, 1 gwei = 10^(-9) eth Using a bidding mechanism, the higher the GasPrice setting, the faster the transaction processing speed The transaction is processed by the miner, and the gas fee is completely collected by the miner The new gas fee mechanism Transaction fee = (baseFee + PriorityFee) * GasUsed Comparing the formula before and after the upgrade, we see that EIP-1559 splits GasPrice into a combination of two rates: baseFee and PriorityFee. baseFee (base fee) baseFee will be automatically adjusted according to the space utilization of the previous block. If the utilization exceeds 50%, the baseFee of the current block will be increased; otherwise, it will be decreased. According to the baseFee calculation formula, the range of baseFee change between adjacent blocks is within ±12.5%: If the space utilization rate of the previous block is 100%, the baseFee of the current block will automatically increase by 12.5% If the space utilization rate of the previous block is 0%, the baseFee of the current block will automatically decrease by 12.5% Unlike the original gas fee mechanism, after the EIP-1559 upgrade, the transaction fee is not completely charged by the miners. Instead, the baseFee will be completely destroyed. PriorityFee (tip) PriorityFee is a tip for miners that still uses a bidding design. If you want your transactions to be packaged in the block as soon as possible, you can set PriorityFee to incentivize miners, and miners will give priority to processing transactions with high PriorityFee. At the same time, users can also set the maximum value of PriorityFee, which is the upper limit of tips paid to miners, also called maxPriorityFee. maxFee (maximum fee) maxFee represents the highest transaction fee that a user is willing to pay for a transaction. Corresponding to the formula, maxFee = baseFee + maxPriorityFee, where both maxFee and maxPriorityFee can be set by the user, and baseFee is automatically given by the algorithm. Note: After the upgrade, the term "miner fee" is no longer appropriate, because the baseFee in the fee is to be destroyed, and only Tip is collected by the miner. Perhaps after the EIP-1559 upgrade, we should abandon the term "miner fee" in the Ethereum ecosystem. EIP-1559 Transaction Fee Calculation Example Before the upgrade Miner Fee= GasPrice *GasUsed After the upgrade Transaction Fee= (baseFee + PriorityFee) * GasUsed maxFee >= baseFee + maxPriorityFee  Possible fee settings, in gwei: Discussion about EIP-1559  EIP-1559 has been debated in the community for 2 years, even now.

How to use Uniswap V3 on imToken?

How to use Uniswap V3 on imToken?

In November 2018, Hayden Adams, founder of Uniswap, launched its initial version, which only supported users to create ERC20-ETH pools. In May 2020, Uniswap launched v2, featuring the addition of ERC20/ERC20 liquidity pools. In less than a year since its launch, v2 has facilitated over $135 billion in trading volume. A year later, Uniswap, which spearheaded the first AMM era, launched v3 in May of this year with two main changes: concentrated liquidity and multiple fee tiers.   Concentrated liquidity In Uniswap v2, liquidity is distributed evenly along an x*y=k price curve, with assets reserved for all prices between 0 and infinity. For most pools, a majority of this liquidity is never put to use. In Uniswap v3, LP’s can concentrate their capital within custom price ranges, providing greater amounts of liquidity at desired prices. In doing so, LPs construct individualized price curves that reflect their own preferences. Notably, LP positions will be represented by non-fungible tokens (NFTs) in Uniswap v3 due to users’ different preferences for price range.   Multiple fee tiers Uniswap v3 offers LPs three separate fee tiers per pair — 0.05%, 0.30%, and 1.00%.  The team behind Uniswap expects like-kind asset pairs to congregate around the 0.05% fee tier and pairs like ETH/DAI to use 0.30%, while exotic assets might find 1.00% swap fees more appropriate. In doing so, LPs will be appropriately compensated for taking on varying degrees of risk.  Note: The following tutorial takes the Chinese interface as an example, and the English interface is operated in the same way.   How to swap? 1. Search Uniswap on the imToken "Browser" page and open it. 2. Click "ETH" and "Select a token" to select the coins you want to swap. 3. If it’s your first time to trade a certain currency, please authorize that currency first. Take USDT-ETH as an example, click "Allow the Uniswap Protocol to use your USDT" to authorize the transaction, and then click "Next" to confirm. After the authorization transaction is sent, "Pending" will be displayed in the bottom left corner of the page, indicating that the transaction is waiting to be processed. 4. After successful authorization, Uniswap will display "You can now trade USDT". Enter the number of tokens you want to trade, then click "Swap" - "Confirm Swap" and confirm the transaction. 5. After the transaction is complete, you can see the asset update when you return to the imToken asset page.   How to add liquidity? 1. Click "Pool" - "+ New Position", select the token you want to add and select a fee tier, 0.05% for stable pairs, 0.3% for regular pairs and 1% for more exotic pairs. 2. Set a price range and you can earn fees as long as the price stays within that range.  Please note: If market prices move outside your specified price range, your liquidity will be removed from the pool and is no longer earning fees.  In this state, your liquidity is composed entirely of the less valuable of the two assets, until the market price moves back into your specified price range or you decide to update your range to account for current prices. So, it is recommended to set a wider price range. 3. Set the deposit amount. If it’s your first time to deposit a certain currency, you need to authorize that currency first. Take USDT as an example, click "Approve USDT" to authorize, and then click "Add" after the authorization is complete. 4. Click "Add" again and wait for the transaction to be processed. Upon success, you can see your positions on Uniswap's pool page. 5. Click "In range" to see the NFT,i.e. your liquidity credential, which is a dynamic image showing information such as pair, fee tier, ID and price range. 6. Return to the imToken asset page and click "Collectibles", then you can see the NFT obtained by depositing tokens in Uniswap v3: UNI-V3-POS. Please note that you should not sell this NFT, as it is a credential that you will use when you withdraw the deposited tokens. Note: The words "Come soon" in the image on the right do not affect the functionality of the Uniswap v3 NFT.   How to withdraw your deposited tokens? 1. Click "Remove Liquidity" and enter the amount of funds to be withdrawn. If you want to withdraw all the funds, click "Max", and then click "Remove". 2. Click "Remove", then click "Confirm" in the pop-up page. You need to wait for the transaction to be processed after it is sent. Upon success, you will get a notification on the Uniswap pool page. When you return to the imToken asset page, you will also see the updated asset amount. After liquidity is removed, you can still see the NFT representing the position on Uniswap and imToken, but the position will now show up as “Inactive “on Uniswap.   V2 to V3 migration guide Uniswap v3 offers a tool for LPs to seamlessly migrate existing Uniswap v2 and Sushiswap positions. 1. Click “More”-“Migrate”. 2. Select a Uniswap v2 or Sushiswap LP position to migrate. Then select the fee tier, set a price range, approve and add.    References: Introducing Uniswap V3 Liquidity Provider & Migration User Guide

Ethereum 2.0: A Complete Guide

Ethereum 2.0: A Complete Guide

What's Ethereum 2.0 Eth2 refers to a set of interconnected upgrades that will make Ethereum more scalable, more secure, and more sustainable. With this upgrade, Ethereum will move from PoW to PoS, and introduce sharding. The Ethereum network will significantly reduce energy requirements, allow more transactions to be processed simultaneously, and improve network security. Eth2 will be phased in, and the Beacon Chain, the first major upgrade to Eth2, went live on December 1, 2020. You can read the official Ethereum 2.0 introduction to learn more about Eth2. Eth2 Roadmap   Recommended Readings ETH2 for Dummies Beyond the Beacon Chain: what's next for Eth2? What to Expect When ETH’s Expecting The State of Eth2, Jan 2021 [AMA] We are the EF's Eth 2.0 Research Team   Beacon Chain Launch date: December 1, 2020 We are currently in the Beacon Chain (formerly Phase 0). As the basis of the PoS consensus, the Beacon Chain provides a consensus foundation for the entire Ethereum network and paves the way for subsequent sharding upgrades.  Users can stake ETH now. However, it should be noted that staking ETH in the deposit contract of the beacon chain is one-way. Once deposited, the staked ETH and accumulated rewards can only be retrieved after Eth2 merges with Eth1.   Recommended Readings The Beacon Chain Ethereum 2.0 explainer you need to read first ETH2.0 Phase 0: basics for new contributors The pros and cons of different Eth2 staking solutions   Merge Estimate: 2021 When ready, Ethereum mainnet will "merge" with the Beacon Chain, becoming its own shard which uses proof-of-stake instead of proof-of-work. This will signal the end of proof-of-work for Ethereum and start the era of a more sustainable, eco-friendly Ethereum.   Recommended Readings A Proof of Stake Design Philosophy   Sharding Estimate: 2022 Shard chains spread the network's load across 64 new chains. Sharding will reduce network congestion and increase transactions per second by creating new chains, known as “shards”.   Recommended Readings How to Scale Ethereum: Sharding Explained   imToken & Ethereum 2.0 The following are the 4 common staking solutions currently available to participate in Eth2 staking:  Self-run node: Users take full self-control for running the client of  Eth1 and Eth2 to maintain their own node and receive the staking rewards. Full custody:  A trusted custodian controls your funds, but it allows users to stake small amounts  (less than 32 ETH) on it.  Custodial staking pool: It offers custodial staking pool and token to reward users who are staking. Solution of Custodial staking pool  provides the liquidity for ETH staking pool, which is based on the solution of full custody. Staking-as-a-Service custody:  Users keep their asset of ETH and control of staking reward to jointly manage and verify nodes with service providers through  2 private keys.   Having at least 32 ETH If you have at least 32 ETH and excellent technical skills, a self-run node will fit you.  However, running your own node can be difficult and you don’t always need to run your own instance. So if you don’t want to be bogged down in endless technical manuals, you can use the imToken Eth2 staking service. imToken 2.9.1 now has full support for Eth2 key generation and staking-as-a-service custody with InfStones, which guarantees the ownership and control of your assets through transparent node information. Meanwhile, you can rest assured about node operation, node validation and maintenance services.   Recommended Readings Become an Ethereum validator with imToken Eth2 staking   Alternatives in imToken Eth2 category Staked InfStones HashQuark Stake.fish RocketPool   Having less than 32 ETH It is recommended to choose a staking pool if you have less than 32 ETH, or aren’t willing to stake that much. Factors such as the service provider's brand, token mechanism and ETH discount should all be taken into account when choosing.

What are the benefits and risks of staking on the Beacon Chain? Benefits: You can earn at least 4.9% APR. Risks: The staked ETH may be slashed due to the misbehavior of the validator.  Meanwhile, the deposited 32 ETH and accumulated rewards will not be transferrable until the Ethereum mainnet is merged with the Beacon Chain, which means they will potentially be locked and non-redeemable for 1 year or longer. Some staking pools may provide a solution for illiquidity, then the safety of the assets will depend on the trustworthiness of the staking pool.   2. Is Eth2 a separate blockchain? Think of Eth2 as a set of upgrades being added to improve the Ethereum we use today. These upgrades include the creation of a new chain called the beacon chain and up to 64 chains known as shards. In a nutshell, Eth2 is the next generation of Ethereum, which aims to improve the scalability, security and programmability of Ethereum while maintaining decentralization.   3. How does the Ethereum mainnet relate to Eth2? The current Ethereum mainnet, Eth1, will merge with Eth2 and move from PoW to PoS.   4. How do I prepare for Eth2? You certainly don't need to do anything. Your ETH will not need changing or upgrading. There's almost certain to be scams telling you otherwise, so be careful.

DApps and Their Risks

DApps and Their Risks

What is a DApp? A DApp, or decentralized application, is a software application that runs on a distributed network. It’s hosted on a peer-to-peer decentralised network, rather than on a centralized server. Currently, a lot of DApp are based on Ethereum and TRON. What are high-risk DApps?  High-risk DApps such as Forsage or Etherchain are those which have the bearing of a pyramid or Ponzi-scheme. Notable warning signs include the following: A guaranteed promise of high returns with little risk Claim to be decentralized and fully transparent, while they are not A consistent flow of returns regardless of market conditions Claim they are cooperating with well-known wallets, exchanges, while they are not  Face difficulties when removing their tokens  Get “rewards” with tokens every time someone joins under you Here’s a list of top 5 high-risk DApps running on Ethereum: Top High Risk DApps, Data from dappradar.com Crypto is full of opportunities, while there are always certain risks behind that. A high-risk DApp can run for a long time without many cracks. You may even have no idea who’s the real person behind it.  Please do your own research before investing in any DApp project. And more importantly, never investing more value into DApps than you can afford to lose.  What is the relationship between imToken DApp browser and those DApps?  When using the imToken DApp browser, some users assume that all these links are safe and they trust these DApp naturally. They even assume these DApps have a partnership with imToken. While it’s not necessarily true.  imToken DApp explorer is like Google search but in a decentralised way. You can enter any links at this explorer and you’ll be able to visit under normal circumstances. And you are responsible for using these third party DApps individually. Users have to pay attention to the DApp they are joining and contact them directly whenever you encounter problems. To protect our users, we add warm signs or block some DApps since they are high risks and running a Ponzi scheme. If you have found any similar DApps, please report them to imToken at hack@token.im.

4 Tips to Keep Your Crypto Assets Safe

4 Tips to Keep Your Crypto Assets Safe

As we all know, imToken is a decentralized wallet. What does it mean? It means that the mnemonic phrase and private key are controlled by you completely - you are the only owner of the wallet. We have several tips to help you keep the asset safe.  1. Download The imToken Fans Group channel on Telegram is not an official imToken chat room. Some users have reported that there are scammers trying to reach them privately and send malicious download links. Please remember that imToken team will never contact you via pm, nor request your confidential information. For imToken support, always email: support@token.im To download imToken, always visit: https://token.im/ 2. Backup  By talking to 200,000+ users, we found that most people lost their coins due to the following reasons:  Forget to back up Back up the wrong mnemonic/ private key Save the mnemonic/ private key in iCloud, or any other cloud service Share it with friends or others  Here are some of the recommendations:  After creating a wallet, please backup your wallet offline in time Back up the wallet by handwriting, or use a mnemonic key box to save the backup Double check if the mnemonic phrase and private key are accurate Do not save the mnemonic phrase through cloud, Facebook, emails, etc Do not share the private key with others 3. Transfer  Due to the nature of the blockchain, you can never reverse a transaction once it’s successful.  When you try to send tokens, please double check if the address you copied is the right one, controlled by an individual or a contract. If the recipient is the token contract itself, those tokens may be lost forever! imToken will warn you when sending tokens to a contract address. 4. DApp - Ponzi Scheme  Another situation involving wallet security is the Ponzi scheme. Such projects often use high returns as the bait. The initiator recruits other ‘investors’ who in turn recruit other investors and so on. Behind the high return is always a high risk. Please be aware! Common Ponzi schemes include: Forsage, Etherchain, etc.  Smart contracts are autonomous, and effectively indestructible. If you find a suspicious dApp, please contact us at hack@token.im, our security team will check and add alerts whenever necessary. Although it’s good to be informed, we hope that you’ll never experience the unpleasant experience in the above.
