Quantum Scanner

Issue Scan Tag

Enter any mainnet Bitcoin address to check its quantum exposure classification, current balance, and CRQC risk score.

Limitations: This tool queries public mempool nodes, not a full node. Fork-chain spends (BCH, BTG) may expose a pubkey on Bitcoin but are not detected here. Off-chain pubkey disclosure (signed messages, PoR schemes) is not detected. P2SH results may be ambiguous.

USD prices are spot, not time-weighted. Data may lag by minutes.
