import "github.com/ChefBingbong/viem-go/utils/transaction"

if err != nil {
  log.Fatal(err)
}

fmt.Printf("Type: %s
", tx.Type)
// Type: eip1559

fmt.Printf("Chain ID: %d
", tx.ChainId)
// Chain ID: 1

fmt.Printf("To: %s
", tx.To)

Returns

• Type: (*transaction.Transaction, error)

The parsed transaction object with all fields populated based on the transaction type.

Parameters

serializedTransaction (required)

tx, _ := transaction.ParseTransaction("0x02ef0182031184773594008477359400809470997970c51812dc3a010c7d01b50e0d17dc79c8880de0b6b3a764000080c0")

Supported Transaction Types

EIP-1559 (0x02)

Parses EIP-1559 transactions with maxFeePerGas and maxPriorityFeePerGas.
