# Historial de tokens de contrato

## Obtenga o escuche el historial de transacciones de cualquier contrato ERC20, ERC721 o ERC1155.

Esta consulta es útil para rastrear el historial de transacciones de un contrato de token en particular.
En este ejemplo, usamos la dirección del contrato del token Skyweaver 0x631998e91476DA5B870D741192fc5Cbc55F5a52E
en la red Polygon. Puede consultar cualquier dirección de contrato en cualquiera de las redes soportadas (pero
asegúrese de consultar el indexer de la red correspondiente).

*Método `GetTransactionHistory` de Sequence Indexer:*

* Solicitud: POST /rpc/Indexer/GetTransactionHistory
* Content-Type: application/json
* Cuerpo (en JSON):
  * `filter` (objeto)
    * `contractAddress` (cadena) -- una dirección de contrato ERC20 / ERC721 / ERC1155

<Note>
  El historial de transacciones de contratos de tokens se conserva durante 30 días en todas las redes con el Indexer (excepto en `arbitrum-sepolia`, donde es de 20 días).
</Note>

**Ejemplo: `GetTransactionHistory` del contrato Skyweaver en Polygon usando un `API_ACCESS_KEY`**

<CodeGroup>
  ```bash cURL
  curl -X POST -H "Content-Type: application/json" -H "X-Access-Key: AQAAAAAAAF_JvPALhBthL7VGn6jV0YDqaFY" https://polygon-indexer.sequence.app/rpc/Indexer/GetTransactionHistory -d '{ "filter": { "accountAddress": "0x631998e91476DA5B870D741192fc5Cbc55F5a52E" }, "includeMetadata": true }'
  ```

  ```typescript Typescript
  // Works in both a Webapp (browser) or Node.js:
  import { SequenceIndexer } from "@0xsequence/indexer";

  const indexer = new SequenceIndexer('https://polygon-indexer.sequence.app', 'AQAAAAAAAF_JvPALhBthL7VGn6jV0YDqaFY')

  // here we query the Skyweaver contract address, but you can use any
  const contractAddress = "0x631998e91476DA5B870D741192fc5Cbc55F5a52E";

  // query Sequence Indexer for all token details / supplies
  // try any contract address you'd like :)
  const filter = {
    contractAddress: contractAddress,
  };

  // query Sequence Indexer for all token transaction history on Polygon
  const transactionHistory = await indexer.getTransactionHistory({
    filter: filter,
  });

  console.log("transaction history of contract:", transactionHistory);
  ```

  ```go Go
  import (
  	"context"
  	"fmt"
  	"log"
  	"net/http"

  	"github.com/0xsequence/go-sequence/indexer"
  )

  func GetTransactionHistory(contractAddress string) {
  	seqIndexer := indexer.NewIndexer("https://polygon-indexer.sequence.app", "AQAAAAAAAF_JvPALhBthL7VGn6jV0YDqaFY")

  	filter := &indexer.TransactionHistoryFilter{
  		ContractAddress: &contractAddress,
  	}

  	metadataOptions := indexer.MetadataOptions{
  		VerifiedOnly:     true, // Set to true if you want to fetch only verified contracts
  		UnverifiedOnly:   false,
  		IncludeContracts: nil, // Provide a list of specific contracts to include, if any
  	}

  	_, history, err := seqIndexer.GetTransactionHistory(context.Background(), filter, nil, nil, &metadataOptions)
  	if err != nil {
  		log.Fatal(err)
  	}
  	fmt.Println("transaction history:", history)
  }
