Use the SpankBank and Token: import { SpankBank， Token } from '@spankdev/spankbank-web3'let spankbank = new SpankBank('0xaad6cdac26aed0894d55bfaf2d3252c6084f5fc4')spankbank .getSpankPoints('0x8ec75ef3adf6c953775d0738e0e7bd60e647e5ef'， 'spankPoints in period 1!') })let spankToken = new Token('0x374f46dc892ecdc9db8bc704175f0485e5185851')spankToken .approve('0xaad6cdac26aed0894d55bfaf2d3252c6084f5fc4'， locked， // Any ledger request (for example， or the Ethereum app hasn't been// started.
