The XRP Ledger (XRPL) is making significant strides towards establishing itself as a prominent force in the decentralized finance (DeFi) landscape through the proposed XLS-66 amendment. This pivotal proposal aims to integrate native lending and borrowing capabilities directly onto the ledger, a move that could revolutionize how users interact with their capital within the XRPL ecosystem. If successfully approved and activated, this amendment will empower users to generate returns on their idle capital, fostering a more dynamic and efficient financial environment. According to Vet, a respected XRPL validator and active community member, this native lending protocol represents what he terms "the final DeFi frontier" for the network, underscoring its potential impact.

The XLS-66d specification, officially titled "Lending Protocol," was first introduced in XRPL version 3.1.0 and is the brainchild of Ripple developers Vytautas Vito Tumas and Aanchal Malhotra. This meticulously designed protocol lays the groundwork by introducing the fundamental primitives required for on-chain credit origination. As detailed in the GitHub proposal, the system is engineered to facilitate "straightforward on-chain uncollateralized fixed-term loans, utilizing pooled funds with pre-set terms for interest-accruing loans." A deliberate design choice was made to forgo the intricate mechanisms typically associated with automated on-chain collateral and liquidation management. Instead, the protocol prioritizes a trinity of core principles: flexibility, reusability, and regulatory compliance.

XRPL researcher Vet further elaborated on the protocol's operational model, emphasizing that lenders will not issue funds indiscriminately. The system is designed with a strong reliance on robust off-chain underwriting and comprehensive risk management practices. Vet clarified, "The lender wouldn't give you XRP in the first place without knowing who you are and doing some off-chain checks on you." This approach highlights that the XRP Ledger's primary role within this framework is to handle "settlement logic largely, ownership and audit trails," ensuring transparency and accountability while allowing external processes to manage the initial vetting and risk assessment.

Despite its transformative potential, the native lending protocol is yet to become operational. For any new feature to be activated on the XRPL, the amendment must garner an 80% supermajority approval from the network's trusted validators. Furthermore, this demanding threshold must be consistently maintained for two consecutive weeks. As of now, the proposal faces a considerable challenge, with its current consensus sitting at a modest 17.14%, reflecting that only 6 validators have voted "Yes," while 29 have either voted "No" or abstained. The path to activation will require significant community engagement and consensus building.
