MetaStreet, a yield infrastructure protocol, structures sources of high-yield into a tradeable asset. This structuring is made possible by MetaStreet v2: The Automatic Tranche Maker ATM, a permissionless loan protocol that automatically organizes depositors' capital in a group based on their risk and return profiles. The protocol introduces Liquid Credit Tokens, which are composable ERC-20 liquid tokens that represent each lender's position in a pool. LCTs allow long-term loans by providing secondary liquidty during the loan period, support floor prices stabilization by deepening the lending markets, and maximize return through full composability in DeFi. MetaStreet seamlessly integrates across NFT exchanges, DeFi platforms, and liquid stake platforms, providing powerful financial infrastructure to scale liquidity. Users can earn yields by depositing funds into permissionless pools that pair any token with NFTs and pool funds with other depositors.
