Transaction inspection
Understand the transaction
before the next step.
Inspect serialized Bitcoin data, compare exact sizes and review outputs without silently signing or broadcasting.
Decode a transactionStart with raw transaction hex
The raw transaction decoder reads serialized transaction data locally and exposes its structure. Review the intended Bitcoin network, inputs and destination outputs. Decoding does not establish confirmation status, prove signatures valid or submit the transaction.
Measure size and identifiers
The size and weight calculator measures bytes, weight and virtual size from actual transaction hex. The TXID calculator labels transaction and witness identifiers. Use these results to compare the data you are inspecting with a public explorer lookup.
Calculate a fee from explicit inputs
The fee calculator uses supplied virtual size and a fee rate in sat/vB. It does not fetch live recommendations. The explorer shows network estimates separately. RBF and CPFP calculators explain fee changes under their documented assumptions, without guaranteeing relay or mining acceptance.
Inspect partially signed transactions
The PSBT decoder reveals transaction and signing metadata locally. The PSBT combiner and finalizer combines compatible information and can finalize supported existing signatures. It does not create transaction signatures or broadcast.
Keep broadcast a separate action
When you already have a signed mainnet transaction, the broadcaster shows outputs and a checked fee before explicit confirmation. Review the destination and amounts carefully. Submission can be irreversible, and confirmation is not guaranteed.
