Usage

example.ts

import {  } from 'wagmi/tempo'
import {  } from './config'

const { ,  } = await ..(, {
  : ['issuer'],
  : '0x20c0000000000000000000000000000000000000',
  : '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
})

.('Role granted:', [0].)
Role granted: true

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 token.grantRoles action and wait for inclusion manually:

import { Actions as viem_Actions } from 'viem/tempo'
import { Actions } from 'wagmi/tempo'
import { waitForTransactionReceipt } from 'wagmi/actions'

const hash = await Actions.token.grantRoles(config, {
  roles: ['issuer'],
  token: '0x20c0000000000000000000000000000000000000',
  to: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
})
const receipt = await waitForTransactionReceipt(config, { hash })

const events = viem_Actions.token.grantRoles.extractEvents(receipt.logs)

Return Type

type ReturnType = {
  /** Transaction receipt */
  receipt: TransactionReceipt
  /** Array of role membership update events */
  value: readonly {
    /** Role identifier */
    role: Hex
    /** Address that received the role */
    account: Address
    /** Address that granted the role */
    sender: Address
    /** Whether the role was granted (true) or revoked (false) */
    hasRole: boolean
  }[]
}
