	client, err := ethclient.Dial("https://matic-mainnet.chainstacklabs.com")
	if err != nil {
		log.Fatal(err)
	}

	receipt, err := client.TransactionReceipt(context.Background(),
		common.HexToHash("0x778c2571b342bc353fd22c6c55f25f7e0842c5cf1aa89b5aded4fb1d2daca851"))

Hi @nathanyan , Matic has its own implementation of geth : GitHub - maticnetwork/bor: Official repository for the Matic Blockchain
