MPT Escrow

Place Multi-Purpose Tokens in escrow on the XRP Ledger.

How MPT escrow works

Escrow allows tokens to be held on-chain with release conditions such as time-based locks or cryptographic conditions. This enables use cases like scheduled payments, conditional releases, and trustless token exchanges.

Escrow requires tfMPTCanEscrow to be set during issuance. This flag cannot be added after the MPT is created.

Prerequisites

The MPT was created with the tfMPTCanEscrow flag enabled
The holder has sufficient tokens to place in escrow
Sufficient XRP for transaction fees and reserves

Finish an escrow

To release tokens from an existing escrow, submit an EscrowFinish transaction:

{
  "payload": {
    "id": "{{intent_id}}",
    "accountId": "{{account_id}}",
    "ledgerId": "xrpl-testnet",
    "parameters": {
      "type": "XRPL",
      "feeStrategy": {
        "priority": "High",
        "type": "Priority"
      },
      "maximumFee": "1000000000",
      "operation": {
        "type": "EscrowFinish",
        "owner": {
          "address": "rOwnerAddress...",
          "type": "Address"
        },
        "offerSequence": 12345678
      }
    },
    "description": "EscrowFinish intent",
    "customProperties": {},
    "type": "v0_CreateTransactionOrder"
  }
}

Parameters

Field	Type	Required	Description
`owner`	object	Yes	The account that created the escrow.
`owner.type`	string	Yes	One of: `Account` (internal account UUID), `Address` (XRPL address), or `Endpoint` (endpoint UUID).
`owner.address`	string	Conditional	The XRPL address that created the escrow. Required when `owner.type` is `Address`.
`owner.accountId`	string	Conditional	Internal account UUID. Required when `owner.type` is `Account`.
`owner.endpointId`	string	Conditional	Endpoint UUID. Required when `owner.type` is `Endpoint`.
`offerSequence`	integer	Yes	The sequence number of the escrow creation transaction.
`condition`	string	No	Hex-encoded PREIMAGE-SHA-256 crypto-condition (if escrow uses condition).
`fulfillment`	string	No	Hex-encoded fulfillment matching the condition (required if condition was set).
`credentialIds`	array	No	Array of hex-encoded credential IDs (if escrow requires credentials).

Conditional escrow

If the escrow was created with a crypto-condition, you must provide both the condition and fulfillment parameters:

{
  "operation": {
    "type": "EscrowFinish",
    "owner": {
      "address": "rOwnerAddress...",
      "type": "Address"
    },
    "offerSequence": 12345678,
    "condition": "A0258020E3B0C44298FC1C149AFBF4C8996FB92427AE41E4649B934CA495991B7852B855810100",
    "fulfillment": "A0028000"
  }
}

Response

A successful request returns the transaction order with status Pending. After confirmation:

The escrowed tokens are released to the destination address.
The escrow object is removed from the ledger.
Any XRP reserve held for the escrow is returned to the creator.
