policy.useCreate

Creates a new transfer policy for token access control. Learn more about transfer policies

Usage

example.ts

import {  } from 'wagmi/tempo'

const  = ..()

// Call `mutate` in response to user action (e.g. button click, form submission)
.({
  : [
    '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
    '0x70997970C51812dc3A010C7d01b50e0d17dc79C8',
  ],
  : 'whitelist',
})

.('Policy ID:', .?.)
Policy ID: 1n

config.ts

import { createConfig, http } from 'wagmi'
import { tempoTestnet } from 'wagmi/chains'
import { KeyManager, webAuthn } from 'wagmi/tempo'

export const config = createConfig({
  connectors: [
    webAuthn({
      keyManager: KeyManager.localStorage(),
    }),
  ],
  chains: [tempoTestnet],
  multiInjectedProviderDiscovery: false,
  transports: {
    [tempoTestnet.id]: 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 policy.create action and wait for inclusion manually:

import { Hooks } from 'wagmi/tempo'
import { Actions } from 'viem/tempo'
import { useWaitForTransactionReceipt } from 'wagmi'

const create = Hooks.policy.useCreate()
const { data: receipt } = useWaitForTransactionReceipt({ hash: create.data })

// Call `mutate` in response to user action (e.g. button click, form submission)
create.mutate({
  addresses: [
    '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
    '0x70997970C51812dc3A010C7d01b50e0d17dc79C8',
  ],
  type: 'whitelist',
})

if (receipt) {
  const { args: { policyId } } 
    = Actions.policy.create.extractEvent(receipt.logs)
