AVOID

"Cross-chain weak link bridges are the most critical point of failure... If an attacker uses a quantum computer to forge one valid proof... it could mean an infinite amount of wrapped assets... effectively draining the bridge funds." Bridges concentrate liquidity in multisig contracts that rely on the exact cryptography (ECC) that quantum computers break. Unlike a decentralized network where you might fork to save the chain, a bridge hack is often instantaneous and irreversible. They are the "soft underbelly" of the ecosystem. Avoid holding tokens of bridge protocols or keeping significant liquidity in wrapped assets until post-quantum standards are standardized across both connected chains. Post-quantum standards are adopted faster than expected, mitigating the risk. |
