Clearpool is the leading decentralized finance credit marketplace, preparing to launch Ozean — the blockchain for RWA yield. Clearpool’s permissionless protocol enables institutions to raise unsecured liquidity directly from DeFi markets, while a separate fully permissioned platform, Clearpool Prime, further meets the compliance needs for wholesale borrowing and lending of digital assets by institutional market participants.

Launched in March 2022, Clearpool has originated over US$620 million in loans with a growing user base spanning both crypto and TradFi institutions such as Wintermute, Jane Street, Fasanara Digital, CoinShares, and others. The protocol launched on the Ethereum mainnet in March 2022, followed by the expansions to Polygon PoS, Polygon zkEVM, Optimism, Mantle Network, Flare Network, Base and Arbitrum. Clearpool is currently building Ozean, the first blockchain for RWA yield built on and supported by Optimism.
