- The new lending model is based on the XLS-66 specification, allowing fixed-term loans with Single Asset Vaults.
- The lending framework uses off-chain underwriting and risk assessment, not requiring on-chain collateral for each loan.
- The fixCleanup amendment groups several fixes into one proposal, following previous cleanup efforts.

- Software packages have moved to packages.xrplf.org with a new XRP Ledger Foundation signing key.
The XRP Ledger (XRPL) has released version 3.4.0, which includes several amendments aimed at enhancing its functionality. A key update is the introduction of Lending Protocol v1.1, which brings changes to the network's lending framework. This includes the implementation of closed-ended vaults and cash-basis accounting. The XRPL's lending loans, based on the XLS-66 specification, are designed to offer fixed-term loans using Single Asset Vaults. Notably, this model relies on off-chain underwriting and risk assessment rather than requiring on-chain collateral for every loan.
However, the activation of these new lending functions is contingent on validator support. Installing version 3.4.0 does not automatically enable them; validators must vote to support the amendment for it to take effect on the network. Developers are also employing formal verification, using mathematical proofs alongside traditional software testing, to ensure the protocol's behavior.
