Cross-Chain Bridge

Bridge COGN ⇄ wCOGN on Ethereum Sepolia & BSC Testnet (live). HTLC atomic swaps are a demo, no external-chain settlement yet.

⚠️ Post-quantum boundary: native COGN is secured by ML-DSA65 (post-quantum). Once bridged, wCOGN on Ethereum is protected only by Ethereum's classical ECDSA, which is not quantum-resistant. COGNITUM's post-quantum guarantee applies to the native COGN side only.
