Bitcoin transaction decoder for raw hex, inputs and outputs

A Bitcoin transaction decoder turns an opaque string of hex into something you can actually read: the version, every input with its previous txid and output index, every output with its value in satoshis, the script type, the decoded address, the witness data and the locktime. Bitcoin Core does this with decoderawtransaction, but that means running a full node. BitcoinDatabase decodes the same structure over a REST call, so you paste a raw transaction hex and get clean JSON back.

You can also decode by txid: give us any confirmed transaction hash and we return the fully decoded transaction from the indexed chain, complete with input addresses and amounts that a raw decode alone cannot resolve. Use it in the API for an app, in SQL for a batch, or in a dashboard for a one-off check. Informational on-chain data only, not financial advice.

Why it works

What you get with transaction decoder

Hex to readable JSON

Pass a raw transaction hex and get back the version, inputs, outputs, script types, decoded addresses, amounts in satoshis, witness data and locktime, the same fields decoderawtransaction returns, without running a node.

Decode by txid too

Give us a confirmed transaction hash and we resolve the full picture from the indexed chain, including the input addresses and spent amounts that a bare raw decode cannot show because they live in prior transactions.

Every script type parsed

Legacy P2PKH, P2SH, wrapped and native SegWit and Taproot outputs are all parsed to their address form and script type, so you read who was paid without decoding scriptPubKey by hand.

What it handles

The indexed Bitcoin chain, queryable your way

Look up an address, a transaction, a UTXO, the rich list or an on-chain metric, by REST API, SQL or dashboard. The same authoritative data, reconciled block-by-block against the canonical chain, without running a node.

Why BitcoinDatabase

One platform, queryable three ways

Not a raw node to sync, not an indexer to build, and not five vendors to stitch together. The fully-indexed Bitcoin blockchain, available as a REST API, as SQL, and as dashboards, on one authoritative dataset.

REST API

Typed JSON for addresses, transactions, balances, UTXOs and metrics. Drop it into apps, wallets, explorers and agents with curl, Python or our SDKs.

SQL access

Run SQL directly against the indexed Bitcoin dataset for ad-hoc analysis, cohorts and exports, the same data the API and dashboards read from.

Compliance-first

Informational on-chain data and analytics only. Entity labels and flow tracing are framed as tooling to support a regulated team's own review, not accusations.

Good questions

Questions about transaction decoder

Send the raw transaction hex to the decode endpoint and it returns readable JSON: version, inputs, outputs, amounts in satoshis, script types, decoded addresses, witness data and locktime. It is the decoderawtransaction result over REST, so you never run Bitcoin Core to parse a transaction.

Yes. Pass a confirmed transaction hash and BitcoinDatabase returns the fully decoded transaction from the indexed chain, including input addresses and spent amounts that a raw hex decode cannot resolve on its own. This is informational on-chain data, not advice.
