Ondo Finance

Ondo Finance brings exposure to US Treasuries on-chain, making it possible for token holders to earn yield daily with highly liquid, bankruptcy-remote, tokenized assets. Ondo significantly broadens the investor base that can capitalize on these yields and put their assets to work in blockchain-based applications, while reducing the friction experienced when converting between stablecoins and tokenized traditional assets.
