The amendment extends two other proposed pieces of XRPL infrastructure (LendingProtocol and SingleAssetVault).
According to RippleX, LendingProtocolV1_1 must activate alongside the original LendingProtocol and SingleAssetVault amendments.
The amendment changes how that pooled capital can be used for lending.
It was included in $XRP Ledger server version 3.4.0, released on Sept. 16. The release formally introduced LendingProtocolV1_1 to 'xrpld.'
Opening validator voting is not the same as activation.
A proposed change must receive support from more than 80% of trusted validators. Furthermore, it must maintain that level of support for two weeks. If support falls back to 80% or below during that period, the two-week countdown resets.
Closed-ended vaults
LendingProtocolV1_1 has introduced the ability to create a second type of Single Asset Vault.
Single Asset Vaults pool one type of asset from multiple depositors and make that capital available to another protocol. A vault can hold $XRP, a trust line-issued token or a Multi-Purpose Token.
An open-ended vault works like an investment pool that remains continuously accessible. Users can deposit capital and receive shares based on the prevailing price per share.
Approving V1_1 alone would not suddenly create a functioning XRPL lending market.
RippleX says all three amendments (SingleAssetVault, LendingProtocol and LendingProtocolV1_1) are required for operational lending.
The Sept. 30 vote should be viewed as a procedural milestone.
