Top 5 Quantum Resistant Crypto Tokens and the Two Signing Every Transaction

Quantum resistant crypto signs transactions with schemes designed to resist a quantum computer, like the ones NIST standardized in August 2024, and only QRL and Quantus among the five tokens below do it on every mainnet transaction. Across three early-October bars Starknet's STRK rose 110.36% on CoinMarketCap (CMC), though its own quantum plan is still a roadmap.

This list grades each claim by scope, meaning the part of the chain a scheme protects and if that part runs on mainnet. Across the same bars, QRL gained 5.77% on CMC and Quantus 5.70% on CoinGecko. The four entries other than STRK had a median gain of 5.23%, while Bitcoin fell 0.44% and Ether 2.70% on CMC.

Top Quantum Resistant Crypto Tokens at a Glance

What Is Quantum Resistant Crypto?

Quantum resistant crypto is a coin whose network signs transactions with a scheme that no known quantum attack can break. Bitcoin and Ethereum sign with elliptic curves, and a large enough quantum computer running Shor's algorithm could work out a private key from the public key that a spent coin leaves on-chain.

NIST published its first three post-quantum standards on 13 August 2024. FIPS 204 defines ML-DSA, the lattice signature that grew out of CRYSTALS-Dilithium. FIPS 205 defines SLH-DSA, a hash-based signature with no state to track, and FIPS 203 covers key exchange.

Two schemes on this list sit outside those three. NIST selected Falcon, the scheme behind Algorand's quantum work and Starknet's test accounts, for a further standard and says that process is underway. QRL's XMSS falls under SP 800-208, a separate NIST recommendation from October 2020 for stateful hash-based signatures.

Where a scheme sits matters as much as which scheme it is. A chain signs each transfer with an account key, proves its history with a proof system and exposes a public key through its address format, and any one of those layers can be quantum resistant while the others are not.

Bitcoin's BIP-360 quantum-resistant address type works on the last of those layers, with an output that keeps public keys out of a quantum attacker's view.

The 5 Quantum Resistant Coins to Watch

No list can name the best quantum resistant crypto by safety, since no scheme here has faced a working quantum computer, so the order runs by scope from every transaction down to a testnet.

1. QRL

The Quantum Resistant Ledger (QRL) became the first blockchain to sign every transaction with the hash-based XMSS scheme when its mainnet launched in 2018, according to QRL's guide to post-quantum blockchain security.

The next version changes scheme. QRL's June 2026 update puts QRL 2.0 (Project Zond) on ML-DSA-87 and proof of stake, running on a testnet with no mainnet date. The named risk is state, since each XMSS key index signs once and a wallet that loses count of its keys exposes its funds.

2. Quantus (QTC)

Quantus is a proof-of-work layer 1 whose mainnet launched on 9 September 2026, and its technology page says that "every transaction on Quantus is signed with ML-DSA-87". It bundles those large signatures into zero-knowledge proofs to keep blocks moving, a design our Quantus (QTC) post-quantum coin explainer breaks down.

CoinMarketCap lists Quantus without a price, so CoinGecko is the only feed here. It valued QTC at about $34.7 million at the early-October close, with fewer than 280,000 coins in circulation against a 21 million cap. That small float priced by a single feed is the named risk, and Phemex has never listed QTC.

3. Algorand (ALGO)

Algorand's state proofs let other chains verify its history, and its state proofs documentation says they're signed with "quantum-safe Falcon keys". It calls that its "first milestone towards post-quantum security".

Accounts came next. Since the v42 consensus upgrade took effect on mainnet on 22 August 2026, any account can opt into Falcon-1024 post-quantum signatures by rekeying, though standard accounts still sign with Ed25519.

Algorand's Falcon work has drawn attention before, and Phemex covered Algorand's rally after Google's Quantum AI paper in April 2026. Across the three early-October bars ALGO slipped 0.86% on CMC, with a $1.07 billion market value on CoinGecko.

It's the one entry with Phemex markets, an ALGO/USDT perpetual and ALGO spot. Futures use leverage, and a leveraged position is closed automatically if losses reach its margin. The named risk is the standard, because Falcon's NIST standard isn't final and Algorand's docs say its deterministic Falcon variant differs from the draft FN-DSA.

4. Starknet (STRK)

Starknet is an Ethereum layer 2 built on STARKs, a proof system resting on hash functions, so the layer that secures every balance has no known quantum weakness. That's the case Starknet's quantum resistance post made on 7 August 2026.

Its accounts are smart contracts, and most still sign with elliptic curves. An experimental, unaudited Falcon-512 account has made a mainnet transfer, and the post says phase one of a three-phase roadmap is underway.

In early October 2026 Starknet posted that it is "actively considering becoming an L1", which it said would make it "the first fully quantum-resistant network, with 2027 as our target". The named risk sits in the verb, because considering is not deciding, and the statement doesn't say how existing apps and users would move over.

5. QANplatform (QANX)

QANplatform runs ML-DSA through a component it calls QAN XLINK, and its quantum-resistant security pagedescribes a post-quantum signature scheme "used to cross-sign accounts". Its roadmap shows XLINK live on a testnet and the MainNet launch still ahead, pending an integration audit and with no date.

QANX rose 4.76% across the three bars on CMC, on only $9,565 of trading on the last one. The market is thin and the feature has no mainnet to run on, and Phemex has never listed QANX.

Which Crypto Is Quantum Resistant?

QRL and Quantus are quantum resistant on every mainnet transaction, QRL since its 2018 launch and Quantus since September 2026. Algorand and Starknet each cover one layer by default, Algorand its state proofs and Starknet its proof system, with post-quantum accounts optional on both. QANplatform's cross-signing has no mainnet yet.

Price ran the other way. Over the three bars that took in Starknet's L1 post, STRK gained about 19 times as much as either of the two chains that already sign everything post-quantum. On those bars a plan with a 2027 target outran two working networks, and Bitcoin and Ether fell.

The company behind Starknet has put quantum work on a live chain before. StarkWare's quantum-safe Bitcoin transaction, mined in August 2026, added a hash-based protection layer to a bitcoin spend without a change to Bitcoin's consensus rules.

That makes STRK a bet on execution. The bridge and the data layer Starknet shares with Ethereum still rely on elliptic-curve cryptography, according to its own post, so the quantum label on STRK describes its 2027 target more than the chain it runs in October 2026.

How to Check a Quantum-Resistance Claim

Four checks separate a working scheme from a slogan, and you can run each one in a few minutes on the project's own pages.

1. Name the scheme, because a real claim names its algorithm, such as ML-DSA-87 or Falcon-1024. A page that says "quantum-safe" without one gives you nothing to check.

2. Find the layer it protects, from account signatures to proofs to addresses, and look for that layer in the project's own docs.

3. Separate mainnet from testnet, since a scheme on a testnet guards tokens with no market value. QRL 2.0 and QAN XLINK count as plans until they reach mainnet.

4. Read the primary page yourself, meaning the project's documentation and NIST's own pages, and treat a price move as a separate fact from the cryptography.

Frequently Asked Questions

What is the most quantum resistant crypto?

No token can be ranked most resistant, because no scheme has faced a working quantum attack. By coverage QRL and Quantus lead. Both sign every mainnet transaction post-quantum, QRL with XMSS since 2018 and Quantus with ML-DSA-87 since September 2026.

Is post quantum crypto the same as quantum resistant crypto?

Yes. Post-quantum cryptography is the term NIST uses for the standards, and quantum resistant is the market's word for a chain that uses them. Neither label says which layer of the chain the scheme protects, so you still need the project's own pages for that.

Is there any quantum proof crypto?

No network can prove it is safe against every future machine. What exists is quantum resistant crypto built on schemes with no known quantum attack, such as XMSS or ML-DSA. Their standing rests on years of peer review and NIST's selection process.

Are any quantum resistant crypto tokens on Phemex?

ALGO is. Phemex offers an ALGO/USDT perpetual and ALGO spot, and the Algorand (ALGO) price page tracks the token. Phemex has delisted its STRK pairs and has never listed QRL, QTC or QANX.

Final Thoughts

The biggest early-October gain on this list went to a chain whose fully quantum-resistant network is still only a target, and that gap is the trade to watch. If Starknet turns "considering" into a decision and moves its accounts off elliptic curves by 2027, the market read it early. If the plan stalls, STRK holds a quantum premium on proofs alone.
