reSync: zkSync Biweekly #1

Covering zkSync news and ecosystem updates.

Welcome to the first installment of reSync, the zkSync update newsletter. Let’s dive into what’s new!

---

Development Updates

• On 2/22 the zkSync 2.0 testnet was released! With this release, new features are included:

  • Native support of ECDSA signatures. Unlike the first version of zkSync and most of the ZK Rollups, no special operation is required to register the user’s private key. Any account can be managed in L2 with the same private key that is used for L1.

  • Solidity 0.8.x support. Deploy your existing codebase with little to no changes required.

  • Web3 API. With small exceptions, our API is fully compatible with Ethereum. This allows seamless integration with existing indexers, explorers, etc.

  • Support for Ethereum cryptographic primitives. zkSync natively supports keccak256, sha256, and ecrecover via precompiles.

  • Hardhat plugin. Allows easy testing and development of smart contracts on zkSync.

  • L1 → L2 smart contract messaging. Allows developers to pass data from Ethereum L1 to smart contracts on zkSync, providing required information to run various smart contracts.

• Contract upgrade initiated for zkSync 1.0. The exact changes released can be found here, but includes the ability to approve an instant upgrade by security council members.

Ecosystem Updates

zkSync won the poll for MakerDAO’s Layer 2 of choice:

Which Layer 2 would you prefer for moving your Dai?

Mute (an AMM) allows gas to be paid with the swapped token:

Mute.io @mute_io

The #MuteSwitch now lets you pay ⛽️ fees with the swap token you are sending. $ETH is no longer needed for non ETH based swaps. Frictionless UX solidifying the path towards the endgame for $ETH 🤌🤌 $MUTE $VOICE #zkrollups

Mute also has some impressive testnet statistics:
