Aurora Quick Facts

Aurora is an Ethereum Virtual Machine (EVM) implemented as a smart contract on NEAR Protocol. Aurora is a solution, that allows developers to execute Ethereum contracts in a more performant environment: The NEAR blockchain. NEAR is a modern layer-1 blockchain which is fast with 2-3 second transaction finalization time, scalable, and carbon neutral. Aurora supports all tools available in the Ethereum ecosystem — MetaMask, Truffle, Hardhat, Remix, etc. Additionally, NEAR’s trustless bridge to Ethereum means even the assets on Aurora are the same as Ethereum.
