Escrow Tutorials
The XRP Ledger supports held payments, or escrows, that can be executed only after a certain time has passed or a cryptographic condition has been fulfilled. Escrows can only send XRP, not issued currencies. You can use these simple features to build publicly-provable smart contracts. This article explains basic tasks relating to held payments.
- Send a time-held escrow
- Send a conditionally-held escrow
- Look up escrows where you are the sender
- Look up escrows where you are the destination
Availability of Escrow
Held payments been enabled by the "Escrow" Amendment to the XRP Ledger Consensus Protocol since 2017-03-31. A previous version of the same functionality was available on the Ripple Test Net by the name "Suspended Payments" (SusPay) in 2016.
When testing in stand-alone mode, you can force the Escrow feature to be enabled locally regardless of the amendment status. Add the following stanza to your rippled.cfg:
[features]
Escrow
You can check the status of the Escrow amendment using the feature command.
Send a Time-Held Escrow
The [EscrowCreate transaction][] type can create an escrow whose only condition for release is that a specific time has passed. To do this, use the FinishAfter field and omit the Condition field.
1. Calculate release time
You must specify the time as whole seconds since the Ripple Epoch, which is 946684800 seconds after the UNIX epoch. For example, to release funds at midnight UTC on November 13, 2017:
JavaScript
// JavaScript Date() is natively expressed in milliseconds; convert to seconds
const release_date_unix = Math.floor( new Date("2017-11-13T00:00:00Z") / 1000 );
const release_date_ripple = release_date_unix - 946684800;
console.log(release_date_ripple);
// 563846400
Python 3
import datetime
release_date_utc = datetime.datetime(2017,11,13,0,0,0,tzinfo=datetime.timezone.utc)
release_date_ripple = int(release_date_utc.timestamp()) - 946684800
print(release_date_ripple)
# 563846400
Warning: If you use a UNIX time in the FinishAfter field without converting to the equivalent Ripple time first, that sets the unlock time to an extra 30 years in the future!
2. Submit EscrowCreate transaction
Sign and submit an [EscrowCreate transaction][]. Set the FinishAfter field of the transaction to the time when the held payment should be released. Omit the Condition field to make time the only condition for releasing the held payment. Set the Destination to the recipient, which can be the same address as the sender.
{% include 'snippets/secret-key-warning.md' %}
$ rippled submit s████████████████████████████ '{
> "Account": "rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn",
> "TransactionType": "EscrowCreate",
> "Amount": "10000",
> "Destination": "rsA2LpzuawewSBQXkiju3YQTMzW13pAAdW",
> "FinishAfter": 563846400
> }'
Take note of the transaction's identifying hash value so you can easily check its final status when it is included in a validated ledger version.
3. Wait for validation
On the live network or the Ripple Test Net, you can wait 4-7 seconds for the ledger to close automatically.
If you're running rippled in stand-alone mode, use the ledger_accept command to manually close the ledger:
$ rippled ledger_accept
Loading: "/home/mduo13/.config/ripple/rippled.cfg"
Connecting to 127.0.0.1:5005
{
"result" : {
"ledger_current_index" : 6,
"status" : "success"
}
}
4. Confirm that the escrow was created
Use the tx command with the transaction's identifying hash to check its final status. In particular, look for a CreatedNode in the transaction metadata to indicate that it created an Escrow ledger object.
5. Wait for the release time
Held payments with a FinishAfter time cannot be finished until a ledger has already closed with a close_time header field that is later than the Escrow node's FinishAfter time.
You can check the close time of the most recently-closed (not yet validated) ledger with the ledger command:
JSON-RPC
{
"method": "ledger",
"params": [
{
"ledger_index": "validated"
}
]
}
6. Submit EscrowFinish transaction
Sign and submit an [EscrowCreate transaction][] to execute the release of the funds after the FinishAfter time has passed. Set the Owner field of the transaction to the Account address from the EscrowCreate transaction, and the OfferSequence to the Sequence number from the EscrowCreate transaction. For an escrow held only by time, omit the Condition and Fulfillment fields.
Tip: The EscrowFinish transaction is necessary because the XRP Ledger's state can only be modified by transactions. The sender of this transaction may be the recipient of the escrow, the original sender of the escrow, or any other XRP Ledger address.
{% include 'snippets/secret-key-warning.md' %}
$ rippled submit s████████████████████████████ '{
> "Account": "rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn",
> "TransactionType": "EscrowFinish",
> "Owner": "rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn",
> "OfferSequence": 373,
> }'
Take note of the transaction's identifying hash value so you can easily check its final status when it is included in a validated ledger version.
7. Wait for validation
On the live network or the Ripple Test Net, you can wait 4-7 seconds for the ledger to close automatically.
If you're running rippled in stand-alone mode, use the ledger_accept command to manually close the ledger:
$ rippled ledger_accept
Loading: "/home/mduo13/.config/ripple/rippled.cfg"
Connecting to 127.0.0.1:5005
{
"result" : {
"ledger_current_index" : 6,
"status" : "success"
}
}
8. Confirm final result
Use the tx command with the EscrowFinish transaction's identifying hash to check its final status. In particular, look in the transaction metadata for a ModifiedNode of type AccountRoot for the destination of the escrowed payment. The FinalFields of the object should reflect the increase in XRP in the Balance field.
Send a conditionally-held escrow
1. Generate condition and fulfillment
XRP Ledger escrows require PREIMGE-SHA-256 Crypto-Conditions. To calculate a condition and fulfillment in the proper format, you should use a Crypto-Conditions library such as five-bells-condition. For fulfillments, Ripple recommends using one of the following methods to generate the fulfillment:
- Use a cryptographically secure source of randomness to generate at least 32 random bytes
- Follow Interledger Protocol's PSK specification and use an HMAC-SHA-256 of the ILP packet as the fulfillment.
Example JavaScript code for a random fulfillment and condition:
cc = require('five-bells-condition');
const fulfillment_bytes = crypto.randomBytes(32);
const myFulfillment = new cc.PreimageSha256();
myFulfillment.setPreimage(fulfillment_bytes);
console.log(myFulfillment.serializeBinary().toString('hex'));
// (Random hexadecimal, 72 chars in length)
console.log(myFulfillment.getConditionBinary().toString('hex'));
// (Random hexadecimal, 78 chars in length)
Save the condition and the fulfillment for later. Be sure to keep the fulfillment secret until you want to finish executing the held payment; anyone who knows the fulfillment can finish the escrow, releasing the held funds to their intended destination.
2. Calculate release or cancel time
A Conditional Escrow transaction must contain either a CancelAfter or FinishAfter field, or both. The CancelAfter field lets the XRP revert to the sender if the condition is not fulfilled before the specified time. The FinishAfter field specifies a time before which the escrow cannot execute, even if someone sends the correct fulfillment. Whichever field you provide, the time it specifies must be in the future.
Example for setting a CancelAfter time of 24 hours in the future:
JavaScript
const rippleOffset = 946684800;
const CancelAfter = Math.floor(Date.now() / 1000) + (24*60*60) - rippleOffset;
// Example: 556927412
Python 2/3
from time import time
ripple_offset = 946684800
cancel_after = int(time()) + (24*60*60) - 946684800
# Example: 556927412
Warning: In the XRP Ledger, you must specify time as seconds since the Ripple Epoch (2000-01-01T00:00:00Z). If you use a UNIX time in the CancelAfter or FinishAfter field without converting to the equivalent Ripple time first, that sets the unlock time to an extra 30 years in the future!
3. Submit EscrowCreate transaction
Sign and submit an [EscrowCreate transaction][]. Set the Condition field of the transaction to the time when the held payment should be released. Set the Destination to the recipient, which can be the same address as the sender. Include the CancelAfter or FinishAfter time you calculated in the previous step.

Sign and submit an [EscrowCreate transaction][] to execute the release of the funds after the FinishAfter time has passed.

Set the Condition and Fulfillment fields to the condition and fulfillment values, in hexadecimal, that you generated in step 1.
Note: If you included a FinishAfter field in the EscrowCreate transaction, you cannot execute it before that time has passed, even if you provide the correct fulfillment for the Escrow's condition. The EscrowFinish transaction fails with the result code tecNO_PERMISSION if the previously-closed ledger's close time is before the FinishAfter time.

}
8. Confirm final result
Use the tx command with the EscrowFinish transaction's identifying hash to check its final status. In particular, look in the transaction metadata for a ModifiedNode of type AccountRoot for the destination of the escrowed payment. The FinalFields of the object should reflect the increase in XRP in the Balance field.

Tip: If you don't know what OfferSequence to use in the [EscrowFinish transaction][] to execute an escrow, use the tx method to look up the transaction that created the escrow, using the identifying hash of the transaction in the Escrow's PreviousTxnID field. Use the Sequence value of that transaction as the OfferSequence value when finishing the escrow.
