# zkSync Era: A ZK Rollup For Scaling Ethereum
[](https://zksync.io/)
zkSync Era is a layer 2 rollup that uses zero-knowledge proofs to scale Ethereum without compromising on security or
decentralization. Since it's EVM compatible (Solidity/Vyper), 99% of Ethereum projects can redeploy without refactoring
or re-auditing a single line of code. zkSync Era also uses an LLVM-based compiler that will eventually let developers
write smart contracts in C++, Rust and other popular languages.

## Disclaimer
zkSync Era has been through lots of testing and audits. Although it is live, it is still in alpha state and will go
through more audits and bug bounties programs. We would love to hear our community's thoughts and suggestions about it!
It is important to state that forking it now can potentially lead to missing important security updates, critical
features, and performance improvements.
