token.setSupplyCap

Sets the supply cap for a TIP-20 token. Requires the default admin role.

Usage

example.ts
import { parseUnits } from 'viem'
import { client } from './viem.config'
 
const { newSupplyCap, receipt } = await client.token.setSupplyCapSync({
  supplyCap: parseUnits('1000000', 6),
  token: '0x20c0000000000000000000000000000000000000',
})
 
console.log('New supply cap:', newSupplyCap)

New supply cap: 1000000000000n

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 { Actions } from 'tempo.ts/viem'
import { parseUnits } from 'viem'
import { client } from './viem.config'
 
const hash = await client.token.setSupplyCap({
  supplyCap: parseUnits('1000000', 6),
  token: '0x20c0000000000000000000000000000000000000',
})
const receipt = await client.waitForTransactionReceipt({ hash })
 
const { args } 
  = Actions.token.setSupplyCap.extractEvent(receipt.logs)

Return Type

type ReturnType = {
  /** New supply cap value */
  newSupplyCap: bigint
  /** Transaction receipt */
  receipt: TransactionReceipt
  /** Address that updated the supply cap */
  updater: Address
}
