Converting from RPC Format
Logs can be converted from their RPC format using Log.fromRpc
:
import 'ox/window'
import { AbiEvent, Hex, Log } from 'ox'
const transfer = AbiEvent.from(
'event Transfer(address indexed from, address indexed to, uint256 indexed value)',
)
const { topics } = AbiEvent.encode(transfer)
const logs = await window.ethereum!.request({
method: 'eth_getLogs',
params: [
{
address: '0xfba3912ca04dd458c843e2ee08967fc04f3579c2',
fromBlock: Hex.fromNumber(19760235n),
toBlock: Hex.fromNumber(19760240n),
topics,
},
],
})
const log = Log.fromRpc(logs[0])
{ address: '0xfba3912ca04dd458c843e2ee08967fc04f3579c2', blockHash: '0xabe69134e80a12f6a93d0aa18215b5b86c2fb338bae911790ca374a8716e01a4', blockNumber: 19760236n, data: '0x', logIndex: 271, removed: false, topics: [ "0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef", "0x0000000000000000000000000000000000000000000000000000000000000000", "0x0000000000000000000000000c04d9e9278ec5e4d424476d3ebec70cb5d648d1", "0x000000000000000000000000000000000000000000000000000000000000025b", '0xcfa52db0bc2cb5bdcb2c5bd8816df7a2f018a0e3964ab1ef4d794cf327966e93', transactionIndex: 145, }
