Bitcoin transaction decoder

Paste a transaction ID to turn raw public-chain fields into a readable map. This tool never asks for a key, seed phrase or wallet connection.

Decode a public transaction

A TXID is public and contains 64 hexadecimal characters. Do not paste a private key, seed phrase, descriptor or unsigned transaction here.

Decoded outputs

#	Address or script	Type	Value
Decode a transaction to inspect its outputs.

Read the shape before the story

A transaction proves that valid inputs authorized new outputs. It does not explain why people moved the coins. One payment may include change; many outputs may be a batch; one input may represent years of earlier activity.

Fee rate is fee divided by virtual size

The total fee is the input value minus the output value. Miners compare fee rate in sat/vB because a small transaction and a large transaction compete for different amounts of block space.

Use the UTXO planner to model a similar shape or open the fee explorer for current block-space conditions.

What the fields mean

Version	Transaction serialization rules used by the sender.
Locktime	A height or time condition; zero usually means no locktime.
Sequence	Can signal relative locks or replace-by-fee behavior.
Weight	Bitcoin’s accounting measure for block capacity.
Confirmations	Depth grows as blocks are added after inclusion.

Public does not mean identity

Addresses are pseudonymous. Avoid labelling a person from transaction shape alone. Chain-analysis guesses can be wrong.

How Bitcoin.now handles tool data

Calculated values

Deterministic tools state their assumptions beside the result. They do not present a model as an executable quote.

Observed values

External observations use read-only public data, retain the latest valid cache, and show freshness when a source is delayed.

Safety boundary

No tool trades, broadcasts, connects a wallet, stores a secret, or gives personal financial advice.

Review the data methodology, editorial policy, and risk disclaimer.

Using bitcoin transaction decoder responsibly

Can a TXID reveal the sender?

A transaction reveals scripts and coin movement, not a verified real-world identity. Labels from explorers or analytics firms are claims that need separate evidence.

Why is an output probably change?

Change detection is a heuristic. Wallet behavior, batching and script types may offer clues, but the chain does not mark one output as payment and another as change.

Can this tool broadcast a transaction?

No. It performs a read-only lookup of an already public TXID. There is no raw-transaction upload, signing, wallet connection or broadcast endpoint.
