Integrating your Protocol or DApp

// you can import both events and functions registries
import { events, functions } from '@boostxyz/signatures'
// ...or individually
import events from '@boostxyz/signatures/events'
import functions from '@boostxyz/signatures/functions'

// both events and functions manifests have the following interface:
type eventsOrFunctionsRegistry = { abi: Record<(Hex | string), AbiItem>, selectors: Record<string, Hex> }
// where string keys are the signature ie: Transfer(address indexed,address indexed,uint256 indexed)

// the event signature we'll be using to compose the action
const knownSignature = "Transfer(address indexed,address indexed,uint256 indexed)"
const selector = events.selectors[knownSignature] // 0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef
const abiItem = events.abi[knownSignature] // {name:"Transfer",type:"event",inputs:[{type:"address",indexed:true},{type:"address",indexed:true},{type:"uint256",indexed:true}]}

// now you have everything you need to construct your event action
const filterOnReceiver: ActionStep = {
  chainid: 8453,
  signature: selector,
  signatureType: SignatureType.EVENT, // We're working with an event
  targetContract: targetContract, // Address of the contract emitting the `Transfer` event
  // We want to target the 'receiver' property on the Transfer event
  actionParameter: {
    filterType: FilterType.EQUAL, // Filter to check for equality
    fieldType: PrimitiveType.ADDRESS, // The field we're filtering is an address
    fieldIndex: 1, // We want to target the second argument (index 1) of the event signature
    filterData: '0xc0ffee', // Filtering based on the recipient's address
  },
};
