Safu

Safu is a yield distribution protocol built on restaking and yield-bearing assets, providing on-chain fallback protection for yield-bearing tokens. Users deposit assets such as sUSDe or eETH into a coverage market and give up part of the yield in exchange for a protected version of the asset, while restakers who opt into the risk supply the capital and earn the extra yield the underlying generates.

Pricing comes from a dynamic yield distribution framework that behaves like an interest-rate curve on lending markets, adjusting the sacrificed share to real-time coverage demand and reducing it when demand falls. The protocol is integrated with Symbiotic's permissionless staking architecture, letting networks and protocols deploy their own coverage parameters for risks such as smart contract vulnerabilities or validator failures.
