raw-transaction-hex-decoder

Raw Transaction Hex Decoder

This library's methods return information of a transaction, given this transaction HEX as input.

Originally forked from marcogbarcellos's repo. Now maintaining it myself and will focus on BNB transaction decode for now. If you want this library to support other coins, please open an issue :)

Supported coins

• Binance
• Bitcoin (UTXO Models)
• Ripple (deprecated in 1.3.0)
• Ethereum (deprecate in 1.3.0)

Install

npm install raw-transaction-hex-decoder

Usage

Binance Chain Raw Transaction Decode

const txHexDecoder = require("raw-transaction-hex-decoder");
let bnbSend = 'ce01f0625dee0a4a2a2c87fa0a210a14d1a42a815fc6a339ecd8bfcd093dd1a835f40e1312090a03424e4210e8922612210a14e0a17a3ec9ddfd1d9c8b4e17df0622c679ffa89812090a03424e4210e89226126f0a26eb5ae987210298013db8d32124d1c11570cd37f8e52297bd18ea561cf990907f7aa03e486d6c1240ee378db6506d180dee42fdc54157c562fdd4d047a9c1c33ef407af6bd435a9023a2e0ebdb3061943a88b3a434d6b2ba8a4c970db218bd38fecf9796de973a43d182720cc011a097369676e61747572652001';
let decodedTx = txHexDecoder.decodeBnbRawTx(bnbSend, 'Transfer');
console.log(JSON.stringify(decodedTx));
