Decode raw Bitcoin and Ethereum transaction hex into a readable field-by-field breakdown.

About Transaction Decoder

Understanding raw blockchain transactions doesn't have to be hard. This tool parses raw hexadecimal transaction data for Bitcoin and Ethereum networks and presents each field in a structured, human-readable format. Perfect for developers, auditors, and blockchain enthusiasts who need to inspect transactions without running a full node.

Bitcoin Transaction Parsing

Decodes transaction version, input count with txid/vout/scriptSig/sequence, output count with value and scriptPubKey, and lockTime from raw BTC hex.

Ethereum Transaction Parsing

Parses RLP-encoded ETH transactions into signature parameters (nonce, gasPrice, gasLimit, to, value, data, v, r, s) with human-readable values.

No Server Dependencies

Everything runs in your browser with vanilla JavaScript. Paste raw hex and get instant results — no data leaves your machine.
