Account.fromMultisig

Instantiates an Account from a native multisig (MultisigConfig) configuration.

The returned account represents the multisig sender – its address is derived from the config. It does not hold a key and cannot sign primitives directly (sign, signMessage, signTypedData throw). Instead, it is used purely to broadcast a multisig transaction: it drives the standard sendTransaction flow, passing the prepared request (carrying the collected owner signatures) through to the chain serializer, which combines the approvals into the multisig signature envelope.

Usage

import { Account } from 'viem/tempo'
 
const owner_1 = Account.fromSecp256k1(
  '0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80'
)
const owner_2 = Account.fromSecp256k1(
  '0x59c6995e998f97a5a0044966f0945389dc9e86dae88c7a8412f4603b6b78690d'
)
 
// Instantiate the multisig account (2-of-2) from its owners and threshold.
const account = Account.fromMultisig({
  threshold: 2,
  owners: [
    { owner: owner_1.address, weight: 1 },
    { owner: owner_2.address, weight: 1 },
  ],
})
 
console.log('Address:', account.address)

Account.fromMultisig accepts a raw config and normalizes it internally (via MultisigConfig.from), so you don't need to call MultisigConfig.from yourself. You can still pass a pre-built MultisigConfig.Config if you have one.

Return Type

The return type is backwards compatible with Viem's Account type, with the multisig config attached.

type ReturnType = MultisigAccount
 
type MultisigAccount = Account & {
  /** Account address, derived from the multisig config. */
  address: Address
  /** Multisig config (normalized via `MultisigConfig.from`). */
  config: MultisigConfig.Config
  /** Account source. */
  source: 'multisig'
  /** Account type. */
  type: 'local'
}

Parameters

config

• Type: MultisigConfig.Config

The multisig configuration, created with MultisigConfig.from. The config is normalized (owners sorted into canonical ascending order) before the address is derived.

config.threshold

• Type: number

The total owner weight required to authorize a transaction.

config.owners

• Type: readonly { owner: Address; weight: number }[]

The list of owners and their voting weights.

config.salt (optional)

• Type: Hex

Optional salt used to derive a distinct multisig address for the same owner set.
