Matter Labs plans to launch zkSync 2.0 to Ethereum's mainnet in 100 days. It has released a full zkSync roadmap and other details about the project's upcoming milestones. zkSync 2.0 will be fully EVM-compatible and will be able to handle any Ethereum smart contract.

Polygon zkEVM is an EVM-equivalent zero-knowledge layer 2. It can run any smart contract or dev tool that can be used on Ethereum, but with the scaling power of ZK tech. Polygon zkEVM rolls up batches of transactions and uses a ZK proof to validate those transactions on Ethereum. The layer 2 provides high throughput, low latency, and low fees.

Revert Finance is the first ever UniV3 liquidity pool autocompounder. Users can simply deposit UniV3 LP tokens into Revert Finance and receive LP fees autocompounded into more LP tokens, resulting in higher yield. Revert Finance takes a 2% fee to cover gas costs.
