Sets the supply cap for a TIP-20 token. Requires appropriate permissions. Learn more about roles

Usage

example.ts

import {  } from 'wagmi/tempo'
import {  } from 'viem'

const  = ..()

// Call `mutate` in response to user action (e.g. button click, form submission)
.({
  : ('1000000', 6),
  : '0x20c0000000000000000000000000000000000000',
})

.('Transaction hash:', .?..)
Transaction hash: 0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef

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.setSupplyCap action and wait for inclusion manually:

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

const setSupplyCap = Hooks.token.useSetSupplyCap()
const { data: receipt } = useWaitForTransactionReceipt({ hash: setSupplyCap.data })

// Call `mutate` in response to user action (e.g. button click, form submission)
setSupplyCap.mutate({
  supplyCap: parseUnits('1000000', 6),
  token: '0x20c0000000000000000000000000000000000000',
})

if (receipt) {
  const { args } 
    = Actions.token.setSupplyCap.extractEvent(receipt.logs)
