Deploy Aave V3 to zkSync 2.0 Testnet

FranklinDAO (Prev. Penn Blockchain) is creating this proposal in partnership with Matter Labs to Deploy Aave V3 on zkSync 2.0 Testnet

Proposal link: https://governance.aave.com/t/deploy-aave-v3-on-zksync-v2-0-testnet/10340

Summary

To support Aave’s multichain mission and expand cross-chain experiences, we propose the deployment of Aave V3 to zkSync 2.0 on behalf of the community.

The zkSync team will submit a snapshot to launch Aave V3 on ZkSync V2 testnet, and thereafter another snapshot for mainnet (when the criteria for DEX liquidity and other items are met).

zkSync ecosystem has over 200 projects committed to launching on mainnet, including top DeFi protocols, infrastructure, on/off ramps, etc. Deploying on zkSync will onboard new users & increase user activity on Aave by decreasing costs compared to Ethereum without security degradation zkSync shares Ethereum’s ethos as a free open-source project with a commitment to personal sovereignty, decentralization and community ownership

About zkSync

zkSync 2.0 is a ZK rollup that supports generalized EVM compatibility for the Ethereum blockchain. The primary benefit of zkSync 2.0 is that developers who have created EVM dApps can port to zkSync 2.0 effortlessly and realize significantly lower gas fees and more transactions per second without compromising on security. zkSync 2.0 is a significant leap forward in Layer 2 technologies with long awaited improvements and benefits for Ethereum developers: EVM Compatible - supporting generalized EVM smart contracts on a ZK rollup making it easy to deploy existing dApps ToolChain Compatible - able to port smart contracts with existing tools Ethos Compatible - aligned with the ethos of decentralization and open-source Certainty - using zero knowledge proofs offering certainty of security not probability Future Proof - ecosystem partners that adopt zkSync 2.0 now will enjoy all future improvements without the need to change their code There is broad consensus that ZK rollups are the endgame for scaling Ethereum. zkSync’s EVM compatibility, ease of use, and composability will accelerate developer and retail adoption. Top researchers including Vitalik Buterin recognize ZK rollups as the long term scaling solution.

Technicalities

• Solidity/Vyper support; recommended to use ^0.8.0 and Vyper ^0.3.3 details
• RPC is public: We fully support the Ethereum JSON API, with some additions for L2-level features. More information here
• The Graph is currently indexing zkSync v1 and v2
• Covalent available immediately after mainnet
• Working on all other plugins (ape, founders, remix, truffle, tenderly)
• Chainlink finalising, deploying shortly after mainnet
• Audits in progress with multiple tier 1 auditors and bug bounty program

Timeline

zkSync has been on testnet since February 2022 and has launched mainnet baby alpha as of October 28th. A timely assessment of the deployment of Aave v3 code to zkSync is important: our team has already tested the smart contract library (mostly key ones) it was compiling and looked like it was working fine.

Proposal Stages:

The zkSync team will first submit a snapshot for testnet deployment, following the community guidelines. Then when the time comes, another snapshot for mainnet (when the criteria for DEX liquidity and other items are met)
