`Multisig.handleRequest`

Creates an RPC request handler that stores multisig approvals and broadcasts a canonical final transaction after quorum. Requests outside the multisig coordination methods pass to the downstream handler unchanged.

Usage

import { Multisig, Storage } from 'viem/tempo'
 
const store = Storage.memory()
const handleRequest = Multisig.handleRequest(
  (request) => rpc.request(request),
  { store },
)
 
const result = await handleRequest({
  method: 'multisig_getOperation',
  params: ['0x23a9cbceb2775b93cd60d3ca7c98435c700aa0d7254850efdce71468d326ddf6'],
})

Use a shared persistent store in production. The in-memory store in this example is process-local.

Return Type

type ReturnType = (request: {
  method: string
  params?: readonly unknown[]
}) => Promise<unknown>

Parameters

Type: (request) => Promise<unknown>

The downstream RPC request handler. The coordinator uses this handler for configuration reads and final transaction submission.

store

Type: Storage.Storage

The authoritative store shared by requests that coordinate the same multisig operations.

RPC Methods

`multisig_approveTransaction`

Adds approvals from a serialized Tempo multisig transaction.

type Parameters = [serializedTransaction: Hex]
type Result = string // Serialized Multisig.Operation.Transaction

Below quorum, the result contains a pending operation. At quorum, the handler broadcasts through eth_sendRawTransaction and returns a successful operation containing transactionHash.

`multisig_approveTransactionSync`

Adds approvals and uses synchronous submission when quorum is reached.

type Parameters = [serializedTransaction: Hex]
type Result = string // Serialized Multisig.Operation.Transaction

Below quorum, this method returns the same pending operation as the asynchronous method. At quorum, the handler broadcasts through eth_sendRawTransactionSync.

`multisig_getOperation`

Gets an operation by its deterministic ID.

type Parameters = [id: Hash]
type Result = string | null // Serialized Multisig.Operation.Operation

The method returns null when the operation is unknown.
