- Specification: XRPLF/XRPL-Standards#239 - Amendment: `SingleAssetVault` - Implements a vault feature used to store a fungible asset (XRP, IOU, or MPT, but not NFT) and to receive shares in the vault (an MPT) in exchange. - A vault can be private or public. - A private vault can use permissioned domains, subject to the `PermissionedDomains` amendment. - Shares can be exchanged back into asset with `VaultWithdraw`. - Permissions on the asset in the vault are transitively applied on shares in the vault. - Issuer of the asset in the vault can clawback with `VaultClawback`. - Extended `MPTokenIssuance` with `DomainID`, used by the permissioned domain on the vault shares.
