Attackathon | XRPL Lending Protocol
The XRP Ledger (XRPL) is a decentralized layer 1 blockchain renowned for its decade-long reliability and stability in tokenizing and exchanging crypto-native and real-world assets.
The XLS-66 specification introduces the XRP Ledger-native Lending Protocol, which facilitates straightforward, on-chain, uncollateralised fixed-term loans with pre-set interest terms. Loan liquidity is sourced from pooled funds, while the design relies on off-chain underwriting and risk management to assess borrowers’ creditworthiness.
