uSEI is a tokenized implementation of SEI designed to enable exposure to SEI across multiple blockchains including Base, Polygon, and Arbitrum. uSEI is backed 1:1 with SEI reserves and issued as an ERC20 onchain. SEI collateral is held with Coinbase Custody and can be redeemed for the underlying SEI by burning the ERC20 token and claiming the underlying SEI collateral. uSEI is designed to bring SEI to DeFi applications, enabling swaps, lending/borrowing, and more.
