Yieldfusion

YieldFusion is a DeFi structured products platform that creates and distributes tokenized instruments through a primary market. For each product it mints two distinct 404-series tokens whose ERC-20 side circulates in V2 and V3 automated market makers, central limit order books, and over-the-counter venues, forming a secondary market. It supports both single-tranche and multi-tranche structures, where a senior tranche carries lower risk with lower return and a junior tranche carries higher risk with higher return.

Built on the Ethereum ecosystem, the protocol brings traditional capital-markets tranching on chain, positioning itself as an on-chain structured-product issuer for DeFi users who want to split risk and return profiles, with AMM and order-book liquidity providing exit channels for the notes.
