IPC Transport

The ipc Transport connects to a JSON-RPC API via IPC (inter-process communication).

Import

import { ipc } from 'viem/node'

Usage

import { createPublicClient } from 'viem'
import { ipc } from 'viem/node'
import { mainnet } from 'viem/chains'
 
const client = createPublicClient({
  chain: mainnet, 
  transport: ipc('/tmp/reth.ipc'), 
})

Parameters

path

• Type: string

IPC Path the transport should connect to.

const transport = ipc('/tmp/reth.ipc')

key (optional)

• Type: string
• Default: "ipc"

A key for the Transport.

const transport = ipc('/tmp/reth.ipc', { 
  key: 'reth-ipc',  
})

name (optional)

• Type: string
• Default: "IPC JSON-RPC"

A name for the Transport

const transport = ipc('/tmp/reth.ipc', { 
  name: 'Reth IPC',  
})

retryCount (optional)

• Type: number
• Default: 3

The max number of times to retry when a request fails.

const transport = ipc('/tmp/reth.ipc', {
  retryCount: 5, 
})

retryDelay (optional)

• Type: number
• Default: 150

The base delay (in ms) between retries. By default, the Transport will use exponential backoff (~~(1 << count) * retryDelay), which means the time between retries is not constant.

const transport = ipc('/tmp/reth.ipc', {
  retryDelay: 100, 
})

timeout (optional)

• Type: number
• Default: 10_000

The timeout for async IPC requests.

const transport = ipc('/tmp/reth.ipc', {
  timeout: 60_000, 
})
