[July 2024] ZKsync Developer update

[uF4No]

Hello developers! Welcome to the July edition of the ZKsync Developer Update. This month, we highlight the latest advancements in the protocol, showcase a range of new and improved development tools, and introduce recent integrations.

Here are the updates for the last month:

🔀 ZKsync 3.0: Introducing the Elastic Chain

After the v24 protocol upgrade, MatterLabs finally unveiled the vision for ZKsync 3.0, the Elastic Chain: a scalable network of ZK rollups designed for seamless interoperability and low-cost transactions.

The ZKsync 3.0 upgrade transforms ZKsync into an elastic network, addressing issues with fragmented liquidity and user experience in multi-chain environments. Key components include the ZK Router, ZK Gateway, and customizable ZK Chains built with ZK Stack. The Elastic Chain aims to enhance user experience by providing a unified ecosystem, allowing easy cross-chain transactions, and maintaining Ethereum-level security. Over 20 new ZK Chains are expected to launch by the end of 2024.

ZKsync at ETHcc[7]

ZKsync was one of the main sponsors at the ETHcc[7] conference in Brussels, engaging with developers through insightful talks and discussions. We had a booth where we onboarded more than 300 developers to ZKsync using ZK Quest, a learn-to-earn platform. Our team actively interacted with the community, showcasing the latest protocol updates and our vision for the future.

Here are the main talks:

• Introducing the Elastic Chain by Alex G.
• Sharding the Future: Redefining App Design with ZK Chains by Daniel Lumi
• Airdrops: Giving Money Away Is Harder Than It Seems by Johnnatan Messias
• Cross roll-up arbitrage and impact of Decun on swap fees by Krzysztof Gogol
• Bringing ZK tech to 650 million in Latam by Matthias Broner, Diego Fernandez
• Developing Secure Multi-Provers with SGX by Porter Adams
• They Meme Well (Legally Speaking): Open-Sourcing in Crypto by Rachel Epstein

🧰 Developer tools

• Remix plugin: New version of the ZKsync plugin for Remix built by Nethermind, with improvements for project compilation and a redesigned UI.
• era-test-node: Our super fast local node for testing was updated with new RPC methods that extend support for Hardhat. You can use era-test-node for testing, replaying transactions, or test transactions locally with a forked version of the ZKsync networks. Find more info in our docs.
• Hardhat plugins: multiple minor bug fixes released in hardhat-zksync including compiler fixes and dependency issues.
• foundry-zksync: release 0.0.3-alpha.1 is now live with fixes in gas estimation for tests and temporarily removing support for deploying missing libraries. Find more info in our docs.
• Infura RPC: ZKsync Era is supported through Infura's DIN service, meaning calls to the network are routed to partner infrastructure providers. Find all available RPC providers in the docs.
• Testnet faucets: new testnet faucets from Alchemy and GetBlock available to get ETH in ZKsync Sepolia testnet. Find a full list of all available faucets in our docs.

⚗️ Alchemy tools on ZKsync

The full suite of developer tools from Alchemy now support ZKsync, including: RPCs, Transfers API, NFT API, Token API, Webhooks and Subgraphs.

Start building on ZKsync with the Alchemy tools.

📚 WTF Academy ZK course

Curious about Zero-Knowledge (ZK) technology but unsure where to start? Look no further than WTF Academy! They’ve launched a comprehensive course covering all the mathematical foundations of ZK. Initially released in Chinese, the first four chapters are now available in English, making it accessible for a wider audience.

🦁 Aragon OSx

Aragon’s OSx and App are now live on ZKsync, enabling projects within the ZKsync ecosystem to launch DAOs and govern protocols onchain. This integration allows for seamless, low-cost voting, robust security, and enhanced user experiences through ZKsync’s scalable network. Aragon’s tech stack, benefiting from native account abstraction, provides intuitive, modular governance solutions for DAOs.
