Is Jupiter (JUP) Quantum Proof?

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

Verdict

JUP is not quantum-proof. It inherits Solana’s classical Ed25519 account model plus program authority risk.

Overview

Jupiter is a major Solana DeFi router; JUP is its token. Holder risk tracks Solana account crypto.
