createProvingConfig

Creates a ProvingConfig for createWalletClient({ proving }) — the adapter that lets a wallet client with a local account build, prove, and broadcast transactions using this handle's network binaries. 'local' mode builds proofs in-process from the WASM binaries; 'delegated' mode submits a proving request to a remote prover service instead.

Usage​

import { createWalletClient, http } from '@provablehq/veil-core'
import { loadNetwork } from '@provablehq/veil-aleo-sdk'

const aleo = await loadNetwork('testnet')
const account = aleo.privateKeyToAccount('APrivateKey1...')

const proving = aleo.createProvingConfig({
  mode: 'delegated',
  networkUrl: 'https://api.provable.com/v2',
  proverUrl: 'https://api.provable.com',
  consumerId: '<consumer-id>',
  apiKey: '<api-key>',
  account,
})

const walletClient = createWalletClient({
  account,
  transport: http('https://api.provable.com/v2', { network: 'testnet' }),
  proving,
})

Returns​

ProvingConfig

An object carrying mode, buildTransaction, buildDeployment, simulate, execute, decrypt, and switchNetwork — the hooks createWalletClient uses to build, prove, and broadcast on behalf of a local account.

Parameters​

mode​

  • Type: 'delegated' | 'local'

Where proofs are produced. 'local' builds proofs in-process using the handle's WASM binaries; 'delegated' submits a proving request to the service at proverUrl.

networkUrl​

  • Type: string

Base URL of the Aleo node the built transaction is queried against and, in local mode, submitted to.

proverUrl​

  • Type: string
  • Optional

Base URL of the delegated proving service. Required when mode is 'delegated'; execute throws without it.

apiKey​

  • Type: string
  • Optional

API key for the delegated proving service's JWT issuance.

consumerId​

  • Type: string
  • Optional

Consumer id used to mint and refresh the JWT for the delegated proving service.

account​

  • Type: LocalAccount<'privateKey'>
  • Optional

Account whose private key signs the built transaction and whose view key decrypts owned record outputs. Required to spend records or decrypt transaction outputs; omit for account-less reads.

confirmationTimeout​

  • Type: number
  • Optional
  • Default: 300_000 (5 minutes)

Milliseconds execute waits for the submitted transaction to reach accepted before it throws a timeout error. A rejected confirmation throws immediately, without waiting out the timeout.
