The Quantum Challenge
Quantum computing is coming for ECDSA
Shor’s algorithm will eventually break the signature scheme that secures most blockchain wallets today. The entire ecosystem — Ethereum, L2s, and beyond — needs to prepare.
The transition is hard, but it’s starting
Ethereum’s roadmap now includes quantum resistance, but upgrading a protocol-level signature scheme means hard forks, new address formats, and wallet migrations. That takes time. On Starknet, you don’t have to wait.
Starknet is ready today.
While the ecosystem works toward protocol-level quantum resistance, Starknet's account abstraction lets you act now. Deploy a new account contract with post-quantum signatures — no protocol change, no hard fork, no migration.
Native Account Abstraction
Signature logic lives in the contract, not the protocol. Every wallet chooses its own verification.
Falcon-512
NIST-standardized lattice-based signatures. Battle-tested math with tight security proofs.
Cheaper than ECDSA
~9.5M L2 gas — only 2x garaga ECDSA, 65% less than secp256r1 syscall. Quantum safety at competitive cost.
Faster than the signature scheme you use today
Falcon-512 verification: ~9.5M L2 gas. secp256r1 via syscall: ~27.4M. Via garaga (pure Cairo): ~4.6M. Post-quantum security at 2x the cost of garaga ECDSA — and quantum-safe.
L2 gas — signature verification (lower is better)
17x calldata compression
512 Zq coefficients packed into 29 felt252 storage slots. 1,030 felts reduced to 62 felts on-chain.
