getCode

Retrieves the source code of a deployed program.

Queries the connected Aleo node, so it hits the network. The result is the program's Aleo instructions text — Veil's analogue of viem's getCode, which returns bytecode. Use it to inspect a program's functions, mappings, and record types before calling it. getProgram is an alias for getCode.

Usage​

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

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

const source = await client.getCode({ programId: 'credits.aleo' })
// 'program credits.aleo;\n\nmapping account:\n    key as address.public;\n    value as u64.public;\n...'

Returns​

string

The program source as Aleo instructions text. Fetches the current edition; use getProgramByEdition for a historical version and getLatestEdition to find the newest edition number.

Parameters​

programId​

  • Type: string

Program (e.g. credits.aleo) whose source to fetch.
