How do I migrate funds from a contract that hardcoded the cipher quantum computers will break?

More than $100 billion in DeFi protocols sits in deployed contracts with hardcoded ECDSA verification or secp256k1 key derivation baked into bytecode that cannot be changed without a proxy upgrade pattern most protocols do not have. Unlike externally owned accounts, which gain signature agility through account abstraction proposals like EIP-7701 targeted for inclusion in the Hegota fork, deployed contract logic has no equivalent escape hatch. The Ethereum Foundation formed a dedicated post-quantum team in January 2026, but its published roadmap addresses wallet recovery paths rather than the contracts where the bulk of the value is custodied. No standard migration path exists for moving assets from quantum-vulnerable contract storage into quantum-resistant alternatives without trusting a privileged multisig or a centralized bridge during the transition.
