Wallet security letter #2: Exchange customer service scams

Wallet security letter #2: Exchange customer service scams

Exchange customer service scams One day at noon, I received a call from someone who stated he was from Huobi, a well-known Chinese exchange, and asked if I was Mr. xxx. He informed me that my account was at risk, suspected of black money trading, and the funds had been frozen. At that time, China's regulatory policies were tightening and I took him for his word that my account was associated with black money. So I confirmed with the scammer the details of my frozen funds and he gave me the exact information of my account and the transactions I recently executed. I have to admit these scammers are really sophisticated.  But thanks to my due diligence, I hung up the phone, opened the App of that exchange to check the status of my account and contacted the customer service again within the App. They told me that the caller was a scammer and my account was safe. As a blockchain practitioner, I consider myself to be intelligent with healthy skepticism. But what about common users? When faced with a sophisticated scammer, the chances of a customer falling for the scam are very high. As of July 15, the imToken security team has received a total of 122 reports of such scams, with users being scammed for nearly 1 million dollars. After communicating with the scammed users, we found out the scheme of the fraudsters: After gaining trust by providing the information about the user's identity and transaction, the scammer tells the user that his account is suspected of black money trading and that the user needs to verify the funds to clear his suspicions, otherwise his account will be frozen. Funds verification process: Download imToken and video Apps such as Zoom, share your phone screen with the fake customer service, and exchange all your digital assets for USDT and deposit them into imToken. The scammer informs you the funds have been received and you need to transfer more USDT to start verification. After a while, the scammer tells you that the system starts to verify and the progress reaches XX%. You need to top up RMB to a designated bank account to complete the verification.Because of the shared phone screen, every step of the process from downloading imToken to backing up the mnemonic is recorded by the scammer. After getting your mnemonic, he then induces you to transfer more assets to the wallet.You think that’s the end of the scam? No, it’s not. After you deposit USDT into imToken, the scammer asks you to transfer another amount of cash on the grounds that the system is stuck or the progress of funds verification has not reached 100%. If you tell him that you don't have money, the scammer will trick you into borrowing money from Alipay or WeChat Loans. The scammer will only hang up the phone when he is sure that he has got all your tokens and fiat money. The imToken security team has analyzed this type of scam and summarized the reasons for the high incidence of such scams in the recent past. Scammers obtain the personal information of exchange users through illegal channels and trick them into believing them. 90% of those scammed have never used a decentralized wallet such as imToken. Scammers are sophisticated and clearly understand the blind spots of users. Take advantage of tightening industry regulatory policies and exchange’s business adjustments. Here are some tips to protect you from this scam: When you receive calls from someone who claims to be some exchange's customer service, just hang up the phone and open the official website or App to check. Never give out your mnemonic and private key! Anyone who induces you to give them out is a scammer! Learn the basics of blockchain wallet security. Why is it so important to backup mnemonic phrases? 5 Common Cryptocurrency Scams & How to Avoid Them What if I forgot my password? What should you do if your assets in the wallet are stolen? Upgraded security system In Wallet Security Newsletter # 1, we talked about the scammers currently thriving on Tron, airdropping tokens such as OZBT, AAMT, FIL, etc. to users. The information contained in the token airdrop informed the user that they could exchange these tokens for TRX on the official website. In response to this scam, imToken 2.9.4 fully upgraded the security system in a way that warns users about risky addresses, as reported by users or discovered by the imToken security team. In June, 36 tokens, 202 DApp sites and 4,754 addresses were marked by the imToken security team as risky. End  If you recognize any risky DApps or tokens, please report to us via support@token.im to help more users avoid being deceived.

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.
