Ink Cryptography & Quantum Risk Profile

Risk: high · Confidence: high · Reviewed: 2026-07-19

Verdict

Profile view: Ink is not quantum-proof. Classical EVM signatures authorize users; exchange-operated infrastructure adds concentrated classical keys.

Overview

This is the Wave 7e network/profile page for Ink (l2).

Ink is a Kraken-associated OP-Stack L2. Quantum education: EOA math plus institutional custody patterns.

Treasuries should document whether value sits in exchange custody or self-custody on Ink.

Verdict hub: /is-quantum-proof/ink. Asset framing: /crypto/ink-eth.

Cryptographic profile

What breaks

  • Classical signatures authorizing ETH value under Shor-class adversaries once public keys are known
  • Custodial hot wallets and exchange operational keys
  • Bridges, issuers, or operator sets outside ordinary user wallets
  • Sequencer / prover / upgrade keys on the L2 path

Mitigations

  • Inventory every key that can move ETH (self-custody, exchange, multisig, protocol roles)
  • Name the host chain and bridge path for every balance
  • Document operator/admin sets for L2s and apps
  • Track ecosystem PQC research; branding is not deployment
  • Use /assessment and claims methodology pages for program framing

FAQ

CEX L2 safer?

Ops model differs; classical public-key assumptions remain until algorithms change.
