Proximity Labs has built the first solution to offer MetaMask compatibility on a non-EVM chain through a smart contract called NETH, which allows you to remotely control a NEAR account using your Ethereum account.
NETH is a smart contract that enables your Ethereum account to sign transactions and remotely control your paired NEAR account, allowing you to directly interact with NEAR dApps using your Ethereum wallet, such as MetaMask.
Deployed on the NEAR side, NETH allows your paired NEAR account to accept transaction details (payload) and the signature from your paired Ethereum account.
