​
Parámetros

​
chainId

ChainId El ID de la red para crear un cliente indexador. Debe ser un ID de red soportado por @0xsequence/network.

​
Hooks relacionados

Para aplicaciones que necesitan trabajar con múltiples redes simultáneamente, considere usar useIndexerClients. Acepta un arreglo de IDs de red y retorna un Map de clientes indexadores, permitiendo operaciones en paralelo entre diferentes redes.

Uso con useIndexerClients

import { useIndexerClients } from '@0xsequence/hooks'

const TransactionFetcher = () => {
  // Get indexer clients for Ethereum mainnet and Polygon
  const indexerClients = useIndexerClients([1, 137])

  // Use the clients to fetch data
  const fetchData = async () => {
    // Get Ethereum client
    const ethClient = indexerClients.get(1)

    // Get Polygon client
    const polygonClient = indexerClients.get(137)

    // Make parallel requests
    const [ethData, polygonData] = await Promise.all([
      ethClient.getTransactionHistory(...),
      polygonClient.getTransactionHistory(...)
    ])
  }
