​
Overview

The AbortIntent endpoint cancels an in-flight intent after you have submitted the abort transaction on-chain. Once the abort transaction is confirmed, call this endpoint to notify Trails so the intent status is updated to ABORTED and any recoverable funds are tracked.

​
Use Cases

  • Cancel a pending intent that has not yet been processed
  • Recover stuck or expired intents
  • Clean up failed cross-chain transactions

​
Request Parameters

​
Required Fields

  • intentId (string): The unique ID of the intent to abort
  • chainId (number): The chain ID where the abort transaction was submitted
  • abortTransactionHash (string): The transaction hash of the on-chain abort transaction

​
Response

  • intentId (string): The ID of the aborted intent
  • status (IntentStatus): Updated status of the intent (typically ABORTED)

​
Examples

​
Abort a Pending Intent

const response = await fetch('https://trails-api.sequence.app/rpc/Trails/AbortIntent', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'X-Access-Key': 'YOUR_ACCESS_KEY'
  },
  body: JSON.stringify({
    intentId: 'intent_abc123',
    chainId: 1,
    abortTransactionHash: '0xabc123...'
  })
});

const { intentId, status } = await response.json();
console.log(`Intent ${intentId} is now ${status}`);

​
With the Trails SDK

import { TrailsClient } from '0xtrails'

const trails = new TrailsClient({ accessKey: 'YOUR_ACCESS_KEY' })

const result = await trails.abortIntent({
  intentId: 'intent_abc123',
  chainId: 1,
  abortTransactionHash: '0xabc123...'
})

console.log('Abort result:', result.status)
You must submit the abort transaction on-chain first and wait for it to be confirmed before calling this endpoint. The abortTransactionHash must correspond to a valid on-chain transaction.
