DeveloperEVM Transaction Decoder
Decode EVM raw transaction hex for Ethereum, BSC, Polygon, Arbitrum, Optimism, Avalanche. View transaction details, gas, value, data, and signatures.
What is EVM Transaction Decoder?
EVM Transaction Decoder is a free tool to decode raw transaction hex data from Ethereum Virtual Machine (EVM) compatible blockchains. It parses signed transactions and displays all transaction details including sender, receiver, value, gas parameters, input data, and cryptographic signatures.
This tool supports all EVM-compatible chains including Ethereum, Binance Smart Chain (BSC), Polygon, Arbitrum, Optimism, Avalanche, Fantom, Base, and more.
Supported EVM Chains
| Chain Name | Chain ID |
|---|---|
| Ethereum Mainnet | 1 |
| Binance Smart Chain (BSC) | 56 |
| Polygon (MATIC) | 137 |
| Arbitrum One | 42161 |
| Optimism | 10 |
| Avalanche C-Chain | 43114 |
| Fantom Opera | 250 |
| Base | 8453 |
| Gnosis Chain | 100 |
| zkSync Era | 324 |
| Polygon zkEVM | 1101 |
| Linea | 59144 |
What is a raw transaction hex?
A raw transaction hex is the serialized, signed transaction data in hexadecimal format. It contains all transaction information including sender, receiver, value, gas parameters, input data, and the cryptographic signature. This format is used to broadcast transactions to blockchain networks.
What information can I decode?
The decoder extracts: Transaction type (Legacy, EIP-2930, EIP-1559), Chain ID, From/To addresses, ETH value, Nonce, Gas limit and price, Input data (for smart contracts), and Signature components (v, r, s) used to verify the transaction.
Which blockchains are supported?
All EVM-compatible blockchains are supported, including Ethereum, BSC (Binance Smart Chain), Polygon, Arbitrum, Optimism, Avalanche C-Chain, Fantom, Base, Gnosis, zkSync Era, Polygon zkEVM, Linea, and any other chain that uses the Ethereum Virtual Machine.
What are transaction types (Type 0, 1, 2)?
Type 0 is the original legacy transaction format. Type 1 (EIP-2930) added access lists for gas optimization. Type 2 (EIP-1559) introduced the new fee market with base fee and priority fee, making gas prices more predictable.
Is my transaction data secure?
Yes! All decoding happens entirely in your browser using JavaScript. No transaction data is sent to any server. The tool only reads and displays the publicly visible information already contained in the signed transaction.
How to Use
- Copy your signed raw transaction hex (starts with 0x)
- Paste it into the input field
- Click 'Decode' button to parse the transaction
- View all decoded transaction details including addresses, value, gas, and data
