Ample

Ample is a prize-linked savings protocol. Depositors put in USDC, keep their principal with no lockup, and the yield the pool generates is pooled and distributed as prizes through a verifiable draw rather than paid out pro rata. Nobody loses their deposit; what varies is whether you win the yield. It is an old idea from retail banking, and the onchain version makes the draw auditable. Ample runs on nine chains.
