Create escrow payments that become available at a specified time and expire at a specified time. 2. Finish an escrow payment. 3. Retrieve information on escrows attached to an account. 3. Cancel an escrow payment and return the XRP to the sending account. [![Escrow Tester Form](/docs/img/quickstart-escrow1.png)](/docs/img/quickstart-escrow1.png) ## Prerequisites Download the [Quickstart Samples](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/quickstart/js/). ## Usage To get test accounts: 1. Open `8.escrow.html` in a browser 2. Choose **Testnet** or **Devnet**. 3. Get test accounts. 1. If you have existing account seeds 1. Paste account seeds in the **Seeds** field. 2. Click **Get Accounts from Seeds**. 2. If you do not have account seeds: 1. Click **Get New Standby Account**. 2. Click **Get New Operational Account**. [![Escrow Tester with Account Information](/docs/img/quickstart-escrow2.png)](/docs/img/quickstart-escrow2.png) ## Create Escrow
You can create a time-based escrow with a minimum time to finish the escrow and a cancel time after which the funds in escrow are no longer available to the recipient. This is a test harness: while a practical scenario might express time in days or weeks, this form lets you set the finish and cancel times in seconds so that you can quickly run through a variety of scenarios. (There are 86,400 seconds in a day, if you want to play with longer term escrows.) To create a time-based escrow: 1. Enter an **Amount** to transfer. 2. Copy the **Operational Account** value. 3. Paste it in the **Destination Account** field. 4. Set the **Escrow Finish (seconds)** value. For example, enter _10_. 5. Set the **Escrow Cancel (seconds)** value. For example, enter _120_. 6. Click **Create Escrow**. 7. Copy the _Sequence Number_ of the escrow called out in the **Standby Result** field. The escrow is created on the XRP Ledger instance, reserving 100 XRP plus the transaction cost. When you create an escrow, capture and save the **Sequence Number** so that you can use it to finish the escrow transaction. [![Completed Escrow Transaction](/docs/img/quickstart-escrow3.png)](/docs/img/quickstart-escrow3.png) ## Finish Escrow The recipient of the XRP held in escrow can finish the transaction any time within the time window after the Escrow Finish date and time but before the Escrow Cancel date and time. Following on the example above, you can use the _Sequence Number_ to finish the transaction once 10 seconds have passed. To finish a time-based escrow: 1. Paste the sequence number in the Operational account **Escrow Sequence Number** field. 2. Click **Finish Escrow**. The transaction completes and balances are updated for both the Standby and Operational accounts. [![Completed Escrow Transaction](/docs/img/quickstart-escrow4.png)](/docs/img/quickstart-escrow4.png) ## Get Escrows Click **Get Escrows** for either the Standby account or the Operational account to see their current list of escrows. If you click the buttons now, there are no escrows at the moment. For the purposes of this tutorial, follow the steps in [Create Escrow](#create-escrow), above, to create a new escrow transaction, perhaps setting **Escrow Cancel (seconds)** field to _600_ seconds to give you extra time to explore. Remember to capture the _Sequence Number_ from the transaction results. Click **Get Escrows** for both the Standby and the Operational account. The `account_info` request returns the same `account_object` for both accounts, demonstrating the link between the accounts created by the escrow transaction. [![Get Escrows results](/docs/img/quickstart-escrow5.png)](/docs/img/quickstart-escrow5.png) ## Cancel Escrow When the Escrow Cancel time passes, the escrow is no longer available to the recipient. The initiator of the escrow can reclaim the XRP, less the transaction fees. If you try to cancel the transaction prior to the **Escrow Cancel** time, you are charged for the transaction, but the actual escrow cannot be cancelled until the time limit is reached. You can wait the allotted time for the escrow you created in the previous step, then use it to try out the **Cancel Escrow** button To cancel an expired escrow: 1. Enter the sequence number in the Standby **Escrow Sequence Number** field. 2. Click **Cancel Escrow**. The funds are returned to the Standby account, less the initial transaction fee. [![Cancel Escrow results](/docs/img/quickstart-escrow6.png)](/docs/img/quickstart-escrow6.png) ## Oh No! I Forgot to Save the Sequence Number! If you forget to save the sequence number, you can find it in the escrow transaction record. 1. Create a new escrow as described in [Create Escrow](#create-escrow), above. 2. Click **Get Escrows** to get the escrow information. 3. Copy the _PreviousTxnID_ value from the results. ![Transaction ID in Get Escrows results](/docs/img/quickstart-escrow7.png) 4. Paste the _PreviousTxnID_ in the **Transaction to Look Up** field. ![Transaction to Look Up field](/docs/img/quickstart-escrow8.png) 5. Click **Get Transaction**. 6. Locate the _Sequence_ value in the results. ![Sequence number in results](/docs/img/quickstart-escrow9.png) # Code Walkthrough You can download the [Quickstart Samples](https://github.com/XRPLF/xrpl-dev-portal/tree/master/_code-samples/quickstart/js/)in the source repository for this website. ## ripple8-escrow.js This example can be used with any XRP Ledger network, _Testnet_, or _Devnet_. You can update the code to choose different or additional XRP Ledger networks. ### Add Seconds to Date This function accomplishes two things. It creates a new date object and adds the number of seconds taken from a form field. Then, it adjusts the date from the JavaScript format to the XRP Ledger format. You provide the _numOfSeconds_ argument, the second parameter is a new Date object. ```javascript function addSeconds(numOfSeconds, date = new Date()) { ``` Set the _seconds_ value to the date seconds plus the number of seconds you provide. ```javascript date.setSeconds(date.getSeconds() + numOfSeconds); ``` JavaScript dates are in milliseconds. Divide the date by 1000 to base it on seconds. ```javascript date = Math.floor(date / 1000) ``` Subtract the number of seconds in the Ripple epoch to convert the value to an XRP Ledger compatible date value. ```javascript date = date - 946684800 ``` Return the result. ```javascript return date; } ``` ### Create Time-based Escrow ```javascript async function createTimeEscrow() { ``` Instantiate two new date objects, then set the dates to the current date plus the set number of seconds for the finish and cancel dates. ```javascript let escrow_finish_date = new Date() let escrow_cancel_date = new Date() escrow_finish_date = addSeconds(parseInt(standbyEscrowFinishDateField.value)) escrow_cancel_date = addSeconds(parseInt(standbyEscrowCancelDateField.value)) ``` Connect to the ledger. ```javascript results = "Connecting to the selected ledger.\n" standbyResultField.value = results let net = getNet() results = "Connecting to " + net + "....\n" const client = new xrpl.Client(net) await client.connect() results += "Connected. Creating time-based escrow.\n" standbyResultField.value = results ``` Get the wallet information based on the account seed values. ```javascript const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value) const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value) const sendAmount = standbyAmountField.value results += "\nstandby_wallet.address: = " + standby_wallet.address standbyResultField.value = results ``` Define the `EscrowCreate` transaction, automatically filling values in common fields. ```javascript const escrowTx = await client.autofill({ "TransactionType": "EscrowCreate", "Account": standby_wallet.address, "Amount": xrpl.xrpToDrops(sendAmount), "Destination": standbyDestinationField.value, "FinishAfter": escrow_finish_date, "CancelAfter": escrow_cancel_date }) ``` Sign the escrow transaction definition. ```javascript const signed = standby_wallet.sign(escrowTx) ``` Submit the transaction. ```javascript const tx = await client.submitAndWait(signed.tx_blob) ``` Report the results. ```javascript results += "\nSequence Number (Save!): " + JSON.stringify(tx.result.Sequence) results += "\n\nBalance changes: " + JSON.stringify(xrpl.getBalanceChanges(tx.result.meta), null, 2) standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address)) operationalBalanceField.value = (await client.getXrpBalance(operational_wallet.address)) standbyResultField.value = results ``` Disconnect from the XRP Ledger. ```javascript client.disconnect() } // End of createTimeEscrow() ``` ### Finish Time-based Escrow ```javascript async function finishEscrow() { ``` Connect to the XRP Ledger and get the account wallets. ```javascript results = "Connecting to the selected ledger.\n" operationalResultField.value = results let net = getNet() results = 'Connecting to ' + getNet() + '....' const client = new xrpl.Client(net) await client.connect() results += "\nConnected. Finishing escrow.\n" operationalResultField.value = results const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value) const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value) const sendAmount = operationalAmountField.value results += "\noperational_wallet.address: = " + operational_wallet.address operationalResultField.value = results ``` Define the transaction. The _Owner_ is the account that created the escrow. The _OfferSequence_ is the sequence number of the escrow transaction. Automatically fill in the common fields for the transaction. ```javascript const prepared = await client.autofill({ "TransactionType": "EscrowFinish", "Account": operationalAccountField.value, "Owner": standbyAccountField.value, "OfferSequence": parseInt(operationalEscrowSequenceField.value) }) ``` Sign the transaction definition. ```javascript const signed = operational_wallet.sign(prepared) ``` Submit the signed transaction to the XRP ledger. ```javascript const tx = await client.submitAndWait(signed.tx_blob) ``` Report the results. ```javascript results += "\nBalance changes: " + JSON.stringify(xrpl.getBalanceChanges(tx.result.meta), null, 2) operationalResultField.value = results standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address)) operationalBalanceField.value = (await client.getXrpBalance(operational_wallet.address)) ``` Disconnect from the XRP Ledger. ```javascript client.disconnect() } // End of finishEscrow() ``` ### Get Standby Escrows Get the escrows associated with the Standby account. ```javascript async function getStandbyEscrows() { ``` Connect to the network. The information you are looking for is public information, so there is no need to instantiate your wallet. ```javascript let net = getNet() const client = new xrpl.Client(net) results = 'Connecting to ' + getNet() + '....' standbyResultField.value = results await client.connect() results += '\nConnected.' standbyResultField.value = results results= "\nGetting standby account escrows...\n" ``` Create the `account_objects` request. Specify that you want objects of the type _escrow_. ```javascript const escrow_objects = await client.request({ "id": 5, "command": "account_objects", "account": standbyAccountField.value, "ledger_index": "validated", "type": "escrow" }) ``` Report the results. ```javascript results += JSON.stringify(escrow_objects.result, null, 2) standbyResultField.value = results ``` Disconnect from the XRP Ledger ```javascript client.disconnect() } // End of getStandbyEscrows() ``` ### Get Operational Escrows This function is the same as `getStandbyEscrows()`, but for the Operational account. ```javascript async function getOperationalEscrows() { ``` Connect to the network. The information you are looking for is public information, so there is no need to instantiate your wallet. ```javascript let net = getNet() const client = new xrpl.Client(net) results = 'Connecting to ' + getNet() + '....' operationalResultField.value = results await client.connect() results += '\nConnected.' operationalResultField.value = results results= "\nGetting operational account escrows...\n" ``` Create the `account_objects` request. Specify that you want objects of the type _escrow_. ```javascript const escrow_objects = await client.request({ "id": 5, "command": "account_objects", "account": operationalAccountField.value, "ledger_index": "validated", "type": "escrow" }) ``` Report the results. ```javascript results += JSON.stringify(escrow_objects.result, null, 2) operationalResultField.value = results ``` Disconnect from the XRP Ledger instance. ```javascript client.disconnect() } // End of getOperationalEscrows() ``` ### Get Transaction Info ```javascript async function getTransaction() { ``` Connect to the XRP Ledger. ```javascript let net = getNet() const client = new xrpl.Client(net) results = 'Connecting to ' + getNet() + '....' operationalResultField.value = results await client.connect() results += '\nConnected.' operationalResultField.value = results results= "\nGetting transaction information...\n" ``` Prepare and send the transaction information request. The only required parameter is the transaction ID. ```javascript const tx_info = await client.request({ "id": 1, "command": "tx", "transaction": operationalTransactionField.value, }) ``` Report the results. ```javascript results += JSON.stringify(tx_info.result, null, 2) operationalResultField.value = results ``` Disconnect from the XRP Ledger instance. ```javascript client.disconnect() } // End of getTransaction() ``` ### Cancel Escrow Cancel an escrow after it passes the expiration date. ```javascript async function cancelEscrow() { ``` Connect to the XRP Ledger instance. ```javascript let net = getNet() const client = new xrpl.Client(net) results = 'Connecting to ' + getNet() + '....' standbyResultField.value = results await client.connect() results += '\nConnected.' standbyResultField.value = results ``` Get the account wallets. ```javascript const standby_wallet = xrpl.Wallet.fromSeed(standbySeedField.value) const operational_wallet = xrpl.Wallet.fromSeed(operationalSeedField.value) ``` Prepare the EscrowCancel transaction. ```javascript const prepared = await client.autofill({ "TransactionType": "EscrowCancel", "Account": standby_wallet.address, "Owner": standbyAccountField.value, "OfferSequence": parseInt(standbyEscrowSequenceNumberField.value) }) ``` Sign the transaction. ```javascript const signed = standby_wallet.sign(prepared) ``` Submit the transaction and wait for the response. ``` javascript const tx = await client.submitAndWait(signed.tx_blob) ``` Report the results. ```javascript results += "\nBalance changes: " + JSON.stringify(xrpl.getBalanceChanges(tx.result.meta), null, 2) standbyResultField.value = results standbyBalanceField.value = (await client.getXrpBalance(standby_wallet.address)) operationalBalanceField.value = (await client.getXrpBalance(operational_wallet.address)) ``` Disconnect from the XRP Ledger instance. ```javascript client.disconnect() } ``` ## 8.escrow.html ```html Time-based Escrow Test Harness
