Enter a Bitcoin address or a 64-character transaction ID (TXID). Balance and stats load for every chain; the transaction graph loads where a keyless explorer is available.

Transactions to fetch: newest for the address (exactly this many are scanned; a single TXID fetches just that one transaction)

Max private-key size (bits): baby-step giant-step searches d < 2^bits (≈√n work; 40+ is slow & memory-heavy)

Balance 0 BTC

Received 0 BTC

Instructions:
1. Paste a Bitcoin TXID/address (the public key is taken from its signatures) OR a raw public key (02/03/04 hex).
2. Baby-step giant-step searches for a small private key up to the chosen bit size and recovers it if d is small.

Educational / read-only tool. Transaction data is fetched live from public block-explorer APIs (blockstream.info, with blockchain.info as a fallback). R-reuse recovery only succeeds on wallets that already leaked their key on-chain through a faulty signer — it demonstrates why ECDSA nonce reuse is catastrophic. Never enter keys for wallets you use.
