Bitcoin Transaction Verifier

WHAT IT DOES

Bitcoin Transaction Verifier is a read-only blockchain security tool that provides comprehensive verification of Bitcoin on-chain activity. It retrieves full transaction details including inputs, outputs, total value, fees, size, weight, and confirmation status. For addresses, it displays current balance, total transaction count, UTXO set with individual values, and recent transaction history. The tool supports both Bitcoin Mainnet and Testnet, making it useful for both production monitoring and development testing. Unlike generic block explorers, this tool presents data in a structured, verification-focused format that highlights UTXO details and confirmation depth.

HOW TO USE

Select the desired Bitcoin network (Mainnet or Testnet) from the dropdown menu. Enter a Bitcoin transaction hash (64-character hex string) to verify its status and view complete input/output details including which outputs have been spent. Alternatively, enter a Bitcoin address (P2PKH, P2SH, or Bech32 format) to view its current balance, UTXO count, and recent transactions. The tool automatically detects whether you entered a transaction hash or an address. Each result includes direct links to Blockstream Explorer for deeper investigation. The EVM wallet bridge remains available for wallet connection but is not required for Bitcoin data queries.

TECHNICAL MECHANISM

The tool connects to the Blockstream.info API, which provides a RESTful interface to Bitcoin blockchain data. For transaction verification, it fetches the raw transaction data and its current status separately, calculating total input value, output value, and fee from the UTXO model. The tool also retrieves confirmation count and block height from the status endpoint. For addresses, it queries the address summary for balance and transaction count, fetches the UTXO list for unspent outputs, and retrieves the most recent transactions from the mempool and recent blocks. All data is presented in satoshi precision converted to BTC with 8 decimal places, maintaining full accuracy for Bitcoin's smallest unit.

WHAT IT CANNOT SEE

This tool cannot verify transactions on non-Bitcoin chains—it is Bitcoin-only. It cannot prove off-chain transaction finality or detect double-spends that have not yet been broadcast to the network. It cannot see transactions that are not yet in the mempool or have been dropped from mempools. The tool does not provide real-time monitoring or alerts, and it cannot predict future transaction confirmations. It also cannot verify the authenticity of off-chain data or detect addresses that are not valid Bitcoin addresses. API rate limits may affect performance during high-volume usage.

PLEASE NOTE

This tool is Bitcoin only. It supports Bitcoin Mainnet and Testnet. No EVM chains, Solana, Tron, or other networks are supported. The EVM wallet bridge is available but not required for Bitcoin data. All data is read-only—no transactions are signed or sent.
