Tools
Bitcoin
Transactions, scripts, fees, mempool, and blockchain data.
Block Explorer
Browse every Bitcoin block from Genesis to the current chain tip.
Mempool Explorer
A self-hosted Bitcoin mempool explorer powered by the open-source Mempool project.
Mempool Acceptance Test
Check whether five independently configured Bitcoin Core and Libre Relay nodes would accept a signed raw transaction without broadcasting it.
Transaction Lookup
Find a transaction across self-hosted nodes and retrieve its serialized hex for local decoding.
Private Bitcoin Transaction Broadcast
Broadcast a signed transaction through my Bitcoin Core node using private broadcast, then observe five-node propagation.
Raw Transaction Decoder
Inspect transaction hex locally in your browser without uploading it.
Fee & Transaction Size Calculator
Estimate transaction weight, virtual size, and fees locally in your browser.
