XRPL vaults can lock XRP from minutes to decades

The XRP Ledger Foundation released xrpld 3.4.0 on Sept. 16. The update adds LendingProtocolV1_1 support for closed-ended vaults and introduces cash-basis accounting for new post-activation vaults.

Closed-ended vaults have three protocol-enforced phases: subscription, investment and redemption. Subscription permits deposits and withdrawals up to a set SubscriptionDate. At the SubscriptionDate the investment phase begins, deposits and withdrawals are blocked and the vault’s capital can fund loans. Redemption starts at the RedemptionDate, when depositors may withdraw their share of proceeds. Both dates are fixed at vault creation and enforced by the ledger.

The implementation allows investment periods as short as 60 seconds and strictly less than 30 years. Single-asset vaults can hold XRP, an issued trust-line token or a Multi-Purpose Token. For an XRP-denominated vault, XRP deposited into the vault is unavailable to that depositor during the investment phase; XRP held elsewhere in the same wallet remains liquid.

Cash-basis accounting applies to vaults created after the accounting activation. Under cash-basis rules, a vault records interest only when a borrower actually pays. Vaults created before activation retain the prior whole-life accounting, which could record scheduled interest at loan origination.

Activation requires XRPL’s on-ledger amendment process. A live node snapshot fetched Sept. 17 showed the base LendingProtocol amendment with 13 of 35 trusted-validator votes and SingleAssetVault at 16 of 35, below the displayed activation threshold of 28. If the amendments activate, newly created loan brokers would be limited to closed-ended vaults; existing open-ended lending objects would remain unchanged.

Locked balances can result from moving already-held XRP into a vault, so the presence of locked XRP in vault balances does not by itself demonstrate new market purchases of XRP. The ledger handles origination, payments and defaults, while underwriting remains off-chain. Borrowers can miss payments, brokers can underwrite poorly, recoveries can be insufficient and first-loss capital may not cover all losses. Cash-basis accounting prevents scheduled interest from appearing as received income before payment arrives but does not remove credit risk.

Adoption of closed-ended vaults depends on applications creating vaults and attracting depositors and borrowers. Measurable indicators include the number of XRP-denominated vaults, total XRP deposited, loan counts and principal originated, patterns of repayments and defaults, realized interest and redemption behavior including repeat deposits and renewed borrowing.

The protocol option enables depositors to exchange immediate liquidity for exposure to loan repayments over a fixed term, with interest recorded only when cash is received. Whether those features are activated and used on the ledger will be determined by the amendment process and subsequent application adoption.
