# Jupiter (JUP) Quantum Readiness Report

> Jupiter has a QRI score of 6/100 and is assessed at Stage 2 (Mitigation / Development) with medium evidence confidence.

Evaluation date: 2026-06-05. Review status: draft. Evaluated scope: JUP governance/ecosystem token (SPL) on Solana mainnet, including Jupiter Exchange protocol admin keys, treasury, and multisig governance. Evaluated under Token Inheritance Rule (7.2) as a standard SPL token lacking custom cryptographic dependencies..

Jupiter (JUP) is a standard SPL governance/ecosystem token on Solana, evaluated under the Token Inheritance Rule (7.2). JUP inherits Solana L1's quantum security posture entirely: all spend authorization, account controls, admin keys, and multisig governance rely on Ed25519 signatures. Solana has published extensive quantum research (Falcon-512 implementations by Anza and Firedancer on GitHub, Project Eleven PQC testnet, 3-step roadmap) and has an optional quantum-resistant Winternitz Vault live on mainnet for 2+ years. However, zero mainnet PQC protection exists at the protocol level — all transactions remain Ed25519-only. Jupiter has not published its own cryptographic inventory, quantum risk assessment, or migration plan for its admin keys, treasury, or multisig. The protocol's upgrade authority and treasury are controlled by Squads Ed25519 multisig, representing high-value quantum targets. With ~$610M market cap fully exposed to long-exposure Ed25519 public keys on-chain, JUP scores 6/100 — capped at 40 by the 'active production spend authorization remains entirely ECC-only' Readiness & Risk Cap, and further constrained to 6 by the near-total absence of production protection, migration coverage, or token-specific quantum preparedness. Users should monitor Solana's PQC migration timeline, as JUP's quantum safety depends entirely on it.
