[September 2024] ZKsync Developer update

[uF4No]

Welcome to the September edition of our monthly developer update! This month, we've made significant progress across several areas, from Hardhat and Foundry compatibility improvements to new tools, tutorials, and protocol updates.

👷👷‍♀️ Hardhat

• Compatibility Update: The latest versions of our Hardhat plugins have made testing and deploying contracts simpler and more streamlined. These new versions (listed below) offer built-in support for EVM-based testing and deployment scripts, making the migration of projects to ZKsync Era easier than ever.
  • hardhat-zksync-ethers plugin version 1.2.1
  • hardhat-zksync-upgradable version 1.6.0
  • hardhat-zksync version 1.2.0
  • Additionally, hardhat-network-helpers version 1.0.12 now supports era-test-node.
• We've also released a new migration guide for Hardhat projects in our documentation, providing step-by-step details to migrate projects.

⛏️ Foundry

• We’ve introduced several updates in foundry-zksync, which enabled the successful deployment of Aave on ZKsync Era. Run foundryup-zksync to upgrade to the latest version and leverage these new features.
• We've published a new migration guide for Foundry projects, now available in our documentation.
• Additionally, we’ve released our version of the Foundry Book for ZKsync, which includes detailed tutorials to get you started.

🧰 Third-Party Tools

• Chainlink CCIP: The Cross Chain Interoperability Protocol is now live on ZKsync Era, enabling cross-chain messaging and token transfers. Read more in the official documentation.
• thirdweb: All the template smart contracts have been updated to support ZKsync Era and ZK Chains. Learn more from their announcement.

📚 Tutorials & Education

We’ve added several new tutorials to the community code resources this month.

• Getting Started with ZK Chains: This tutorial provides a comprehensive guide on how to deploy and interact with custom ZK chains.
• Smart Account with WebAuth: Learn how to integrate WebAuthn into your smart accounts to enable secure, passwordless authentication. This tutorial guides you through the implementation of WebAuthn-based signature verification and transaction signing on ZKsync.
• Multi-Signer Paymaster: This tutorial introduces the concept of a permissionless paymaster contract that supports multiple signers.

⛓️ Protocol Updates

• Prover API: We’ve taken the first steps towards decentralizing proof generation through our new Prover API. The API provides two key endpoints: batch input and proof verification. With these endpoints, third-party developers can retrieve batch data, generate proofs, and compare them with the live proofs generated by the system. Read more in the Mirror post.
• TEE Proofs: In addition to the Zero-Knowledge (ZK) proofs that have been a core part of ZKsync, we’ve recently started generating state transition proofs within a Trusted Execution Environment (TEE). These TEE proofs act as an additional layer of security, making ZKsync Era the first rollup with multiple proof types. TEE proofs can be accessed using the unstable_getTeeProofs RPC method. Currently, they are running in "shadow mode," but will be enabled in an upcoming update.
