Ethereum is growing. But with its success come higher gas fees. Luckily, Layer 2 solutions are here to solve that. Therefore we are excited to present to you: Full native support for zkSync on imToken. Now in your favorite app store!

We would like to thank Matter Labs for their support! You can read more about them in our earlier announcement here.

zkSync brings lower fees, instant confirmations to imToken

With Ethereum’s growing usage, come higher gas fees. That’s not only annoying, but also leaves out ‘cheaper’ use cases like minting NFTs or playing on-chain games. However, there are already a number of scaling solutions released and others coming to mainnet in the coming months. Now it’s time for wallets to integrate.

At imToken, we have been following and talking to many (if not all) Layer2 solutions. After some research and adding a custom node feature, we decided to natively integrate zkSync.

zkSync is a ZK-Rollup developed by Matter Labs that makes crypto payments cheaper already today, and is planned to scale arbitrary smart contracts on Ethereum soon (i.e. August). It uses zero-knowledge proofs and on-chain data availability to keep users' funds as safe as though they never left the mainnet. Learn more details on their website.

For you, the user, zkSync brings lower miner fees, instant confirmations on transactions and finality within minutes. Therefore, we are excited to introduce native support for zkSync in the latest update of the imToken wallet app. Update to the latest imToken and experience zkSync already today!

How to use zkSync on imToken

To use zkSync on imToken, open your imToken wallet app, switch to the "My profile" page, click "Explore" and enable zkSync.

imToken & Layer 2

We presented our first imToken app at the Ethereum Devcon in Shanghai in 2016. Since then, we are committed to developing for and within the Ethereum ecosystem. Now that Layer 2s are here to stay, supporting Layer 2 solutions comes natural to us. 

In addition to natively supporting zkSync in the wallet, we have also added a Layer 2 section in the DApp browser, which includes an assortment of Layer 2 and sidechain DApps. To be able to use those more easily, we also support EIP-3085 and allow users to set custom nodes.

More scalability solutions are coming and we are looking forward to helping scale the ecosystem!
