Solana Labs Warns Ethereum L2s Are Not Quantum Safe
Solana Labs co-founder warned that Ethereum Layer 2s are not quantum safe and told users to abandon all hope.Most Ethereum L2s rely on ECDSA signatures vulnerable to quantum computers running Shors algorithm.Solana leads with Falcon-512 implementation as the crypto industry shifts toward quantum resistance. On May 2, 2026, Solana Labs co-founder Anatoly Yakovenko warned that Ethereum (ETH) Layer 2 solutions (L2s) are not quantum safe, urging users to “abandon all hope” in response to a developer update showcasing Solana‘s Falcon-512 verification suite and its production hardening. The remarks highlight Solana’s progress in post-quantum cryptography, while Ethereum L2s remain vulnerable. Solana Founder Says Ethereum L2s Are Not Quantum Safe Solana Labs co-founder Anatoly Yakovenko, known as @toly on X, has publicly stated that Ethereum L2s are not quantum safe, urging users to “abandon all hope.” This comment quoted an earlier post celebrating Solana‘s advancements, which included an image of GitHub’s work on Falcon-512 post-quantum signature verification and suggesting the network is about to “quantummogg” competitors. Why Ethereum L2s Remain Exposed to Quantum Threats Ethereum L2s remain exposed because they still rely on the same quantum-vulnerable cryptographic primitives as Ethereum L1. Elliptic Curve Digital Signature Algorithm (ECDSA) signatures (secp256k1) are used by nearly all user wallets on
