getAmendmentDeploymentTransaction

Retrieves the id of the transaction that applied a specific amendment to a program edition.

Aleo programs are upgradeable. A program upgrade creates a new edition of the program, and amendments are the upgrade transactions that produced each edition. Use getAmendmentDeploymentTransaction when tracing how a program changed: getAmendmentCountByEdition gives the number of amendments, and this resolves each one to its transaction. Queries the connected node, so it hits the network.

Usage​

import { createPublicClient, http } from '@provablehq/veil-core'

const client = createPublicClient({
  transport: http('https://api.provable.com/v2', { network: 'mainnet' }),
})

const txId = await client.getAmendmentDeploymentTransaction({
  programId: 'token.aleo',
  edition: 0,
  amendment: 0,
})
// 'at1...'

Returns​

string | null

The transaction id (at1...), or null if no such amendment exists.
