zone.requestWithdrawal

Requests a withdrawal from a zone to the parent Tempo chain.

Usage

import { parseUnits } from 'viem'
import { client } from './zones.config'
 
const { receipt } = await client.zone.requestWithdrawalSync({
  amount: parseUnits('100', 6),
  token: '0x20c0000000000000000000000000000000000001',
})
 
console.log('Transaction hash:', receipt.transactionHash)

import { privateKeyToAccount } from 'viem/accounts'
import { createClient } from 'viem/tempo'
import { http, zoneModerato } from 'viem/tempo/zones'
 
export const client = createClient({
  account: privateKeyToAccount('0x...'),
  chain: zoneModerato(7),
  transport: http(),
})

Asynchronous Usage

The example above uses a *Sync variant of the action, that will wait for the transaction to be included before returning.

If you are optimizing for performance, you should use the non-sync zone.requestWithdrawal action and wait for inclusion manually:

import { parseUnits } from 'viem'
import { client } from './zones.config'
 
const hash = await client.zone.requestWithdrawal({
  amount: parseUnits('100', 6),
  token: '0x20c0000000000000000000000000000000000001',
})
const receipt = await client.waitForTransactionReceipt({ hash })

type ReturnType = {
  /** Transaction receipt */
  receipt: TransactionReceipt
}
