Frequently Asked Questions
Yes! In 'Raw Hex' mode, our advanced parser runs entirely client-side in your browser. Absolutely zero network calls are made, meaning your private transaction data, unbroadcasted hexes, and custom script arrays never leave your device.
Absolutely. The robust internal parsing engine accurately maps Legacy (P2PKH, P2SH), Native SegWit (P2WPKH, P2WSH), and Taproot (P2TR). It explicitly decouples the ScriptSig and ScriptPubKey, displaying both the raw Hex and the decoded Assembly (ASM) opcodes.
When you provide a Transaction ID, the tool queries public Bitcoin nodes to fetch the raw bytes and advanced output metadata. It then calculates the exact miner fee, fee rate (sat/vB), block confirmations, and visualizes if specific outputs have already been spent.
Yes. Developers can seamlessly switch between Bitcoin Mainnet, Testnet, and Signet to parse experimental transactions or fetch live states from the corresponding network environments.
Yes. Witness data is deeply mapped and intelligently labeled (e.g., [Signature], [Public Key]). If an output contains an OP_RETURN, the tool automatically decodes the embedded hex payload into readable ASCII text for instant debugging.
