 zkEVM Contracts is a library of smart contracts targeted at developers who wish to quickly build and deploy their smart contracts on the Immutable zkEVM, a general-purpose permissionless L2 zero-knowledge rollup. The library allows developers to build on contracts curated by Immutable, including (but not limited to):
 
-* Token presets, e.g. ERC721

-* Bridging contracts

-* Marketplace and AMM contracts

-* Smart Contract Wallets

 These contracts are feature-rich and are the recommended standard on Immutable zkEVM intended for all users and partners within the ecosystem.
