Solidity
Solidity is an object-oriented, high-level language for implementing smart contracts targeting the Ethereum Virtual Machine (EVM). The ICP execution environment is based on WebAssembly and is not directly EVM compatible, but canister smart contracts are powerful enough to host an EVM implementation. Currently, there exists one such implementation, the Bitfinity EVM.
Bitfinity EVM
The Bitfinity EVM is an EVM implementation based on REVM. It provides an RPC interface that is compatible with the Ethereum JSON-RPC API. This means that existing Ethereum tools and libraries, such as MetaMask, Hardhat and Foundry, can be used to interact with the EVM and provide a similar developer and user experience.
For more information, please refer to the official Bitfinity EVM documentation.
