Raw Ethereum Transaction Decoder

Parse a serialized legacy, EIP-2930, EIP-1559, or EIP-4844 Ethereum transaction without broadcasting it.

Calculated locally

Inspect a serialized Ethereum transaction

The decoder parses signed or unsigned serialized bytes locally and never broadcasts them.

Result

Your manual estimate

Calculated locally
Method

How this calculator works

01

Paste signed or unsigned serialized transaction hex to inspect the fields locally.

02

CoinCalcs validates the manual inputs and applies this published model: serialized transaction bytes → typed transaction fields

03

The result is calculated locally in the browser and is not sent to CoinCalcs or a market-data provider.

Formula

The calculation

serialized transaction bytes → typed transaction fields
Example

A concrete scenario

A type-2 transaction exposes chain ID, nonce, recipient, value, gas limit, fee caps, access list, data, and signature fields.

Known limits

What this estimate cannot guarantee

  • Parsing does not simulate execution, verify the destination, guarantee signature validity, or broadcast the transaction.
  • The result is only as current and accurate as the assumptions entered in the form.
  • The output is educational scenario arithmetic, not financial, investment, tax, legal, or security advice.
