XRP Ecosystem Achieves Major Breakthrough: XLS-66 Lending Protocol Opens New On-Chain Yield Path

The XRP Ledger (XRPL) has officially introduced the XLS-66 lending protocol, marking a crucial step in its decentralized finance (DeFi News) capabilities. Proposed by Ripple's core developers Vytautas Vito Tumas and Aanchal Malhotra, the protocol was launched with XRPL version 3.1.0, aiming to achieve native on-chain lending functionality without relying on Ethereum or other smart contract platforms. Unlike mainstream DeFi News protocols that depend on automated liquidation bots and on-chain collateral management, XLS-66 adopts a unique "off-chain audit, on-chain settlement" design. Before a loan is issued, borrowers must complete traditional financial processes such as identity verification and credit assessment to ensure risk control. The blockchain is only responsible for recording loan contracts, repayment schedules, and transaction trails, enhancing transparency and auditability.

The core of the protocol consists of two types of on-chain objects: LoanBroker and Loan. LoanBroker is created by the lending operator to store protocol parameters, manage fee structures, and risk buffer funds (First-Loss Capital). The Loan object carries the specific contract terms between the borrower and the operator, including interest rates, repayment cycles, and status updates. The entire lifecycle covers nine transaction types, from loan creation and issuance to repayment and final liquidation. In terms of yield mechanisms, the protocol supports three interest rate models: standard principal interest rate, overdue penalty interest, and early repayment preferential interest rate. In addition, LoanBroker can charge management fees, loan issuance fees, periodic service fees, and special early/late fees, but only if sufficient risk buffer funds have been deposited, ensuring capital security.

To enhance compliance, the protocol incorporates two key mechanisms: clawback and freeze. Asset issuers can, in accordance with compliance requirements, legally recover funds from specific accounts or temporarily freeze an account's asset sending and receiving permissions, while debt obligations continue to be in effect. The risk buffer fund, as a core risk control tool, is deposited by the lender in proportion to the total loan amount to cover partial default losses and reduce systemic platform risk. This innovative design has been dubbed "the last DeFi News frontier of the network" by XRPL community veteran Vet. It not only provides XRP holders with a new channel to obtain stable yields without having to detour through Ethereum, but also demonstrates Ripple's forward-looking layout in building compliant financial infrastructure.
