Test script:

)

func main() {
	client, err := ethclient.Dial("https://rpc.scroll.io")
	if err != nil {
		panic(err)
	}
	defer client.Close()

	// Fetch the transaction receipt
	receipt, err := client.TransactionReceipt(context.Background(), common.HexToHash("0xcdb8b4fcb9493a51a37f85e84f4e1e37cdfaa9037a6e6663153ac510f65b3b3c"))
	if err != nil {

	}

	// Encode the receipt using RLP encoding
	var buffer bytes.Buffer

	}

	// Decode the receipt back from RLP encoding
	decodedReceipt := new(types.Receipt)
	stream := rlp.NewStream(&buffer, uint64(buffer.Len()))
	err = decodedReceipt.DecodeRLP(stream)
	if err != nil {

	}

	// Convert the decoded receipt to a JSON string
	decodedReceiptJSON, err := json.MarshalIndent(decodedReceipt, "", "  ")
	if err != nil {

	}

	// Print the JSON string of the decoded receipt
	fmt.Println(string(decodedReceiptJSON))
