MetaMask, the world’s leading self-custodial web3 wallet developed by Consensys, today announced a strategic integration with Sei, a fast-growing Layer-1 blockchain platform. This development brings native support for the Sei network into MetaMask, enabling MetaMask’s users to seamlessly access Sei’s ecosystem of decentralized applications (dapps) and Sei-native assets from within their wallet.
