policy.create

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

Usage

Use the policy.create action on the Wagmi config to create a new transfer policy.

import { Actions } from 'tempo.ts/wagmi'
import { config } from './wagmi.config'
 
const { policyId, policyType, receipt } = await Actions.policy.createSync(config, {
  admin: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
  addresses: [
    '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
    '0x70997970C51812dc3A010C7d01b50e0d17dc79C8',
  ],
  type: 'whitelist',
})
 
console.log('Policy ID:', policyId)
Policy ID: 1n

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 { Actions } from 'tempo.ts/wagmi'
import { Actions as viem_Actions } from 'tempo.ts/viem'
import { waitForTransactionReceipt } from 'wagmi/actions'
import { config } from './wagmi.config'
 
const hash = await Actions.policy.create(config, {
  admin: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
  addresses: [
    '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
    '0x70997970C51812dc3A010C7d01b50e0d17dc79C8',
  ],
  type: 'whitelist',
})
const receipt = await waitForTransactionReceipt(config, { hash })
 
const { args: { policyId } } 
  = viem_Actions.policy.create.extractEvent(receipt.logs)

  /** Address that created the policy */
