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.

Instructions:\n1. Enter a Bitcoin TXID (64 hex) or an address.\n2. Every input\u2019s ECDSA signature (R, S, Z) is extracted and R-reuse pairs recover the private key.
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.
