Does quantum-safe cryptography slow down Ethereum?

Yes, expect higher gas fees (20-50% possible), bigger tx sizes, and validator strain—but redesigns like verkle trees will mitigate.

When will Ethereum go quantum-safe?

Likely 2027+ via major fork (post-Pectra); testing now, but full rollout years out.

Is my ETH safe from quantum attacks today?

Short-term yes, but migrate to quantum-safe addresses soon—legacy ones vulnerable post-2030.
