Solana signs with Ed25519. Ethereum signs with ECDSA. A quantum computer reads both in minutes. Qrypt signs with Falcon and CRYSTALS-Dilithium instead, the lattice signatures NIST standardised for this exact threat. Solana and every EVM chain, across a cold wallet, a mobile app, and a browser extension.
Cold for storage. Mobile for daily life. Extension for the dApps you already use. One key model, three surfaces, Solana and every EVM chain, every signature post-quantum.
An air-gapped hardware wallet that signs Solana and EVM transactions with lattice cryptography. Connects through QR codes, never USB. Your seed leaves the device only when you say it does.
A full post-quantum wallet on iOS and Android. Solana and every EVM chain in one feed. Pair with the cold wallet over QR for hardware signing, or run standalone with hybrid keys.
A browser-toolbar wallet for Chromium, Firefox, and Safari. Sign any Solana or EVM dApp with a post-quantum signature. Pair with the cold wallet for hardware-backed signing.
The device never opens a network connection. It signs what you show it on screen, in a language no quantum computer can read back. Then it gives you a QR, and goes quiet again.
Ships Q4 2026. Limited first run. No charge until shipment.
Solana rides on Ed25519. The EVM rides on ECDSA. A quantum computer breaks both. Every signature in the Qrypt stack comes from a NIST-standardised scheme instead, chosen per chain and bound to one key model. Falcon signs Solana, Dilithium signs the EVM.
Every EVM wallet derives a public key from a private key on an elliptic curve. Shor's algorithm reverses this in polynomial time on a sufficiently large quantum computer. Once a public key is on chain, it is harvested forever.
Solana signs every transaction with Ed25519, an elliptic-curve scheme over Curve25519. It rests on the same discrete-log hardness as ECDSA, and Shor breaks it the same way. Solana's throughput exposes more public keys in a day than Bitcoin does in a month.
An NTRU-lattice signature with the most compact post-quantum signature shipping today. Standardised by NIST as FIPS 206. Its small size fits Solana's high throughput, where every byte on chain counts. Qrypt signs Solana transactions with Falcon.
A lattice signature whose hardness rests on Module Learning With Errors, a problem quantum computers offer no known shortcut for. Standardised by NIST as FIPS 204 in 2024. Qrypt signs EVM transactions with Dilithium-3.
Hash-based signatures with no algebraic structure. Slow and large, but the most conservative post-quantum option known. Used as a long-term escape hatch should any lattice scheme weaken, on either ecosystem.
While chains and dApps still expect the old curves, Qrypt runs a hybrid signature: the classical scheme in parallel with the lattice one. The transaction stays compatible. The security inherits the stronger of the two.
A side-by-side of the wallet you have today and the wallet you can move to. Two columns. Same job. Different cryptography.

Wallet balance up top, send and receive and swap a tap away. Portfolio reads SOL, stables, and BTC side by side, with recent activity beneath. Solana and every EVM chain in one feed, no second app to open.
Pay with Apple Pay, Google Pay, or a card. Quotes from P2P providers and on-ramps are compared inside the screen so you see the best price before you commit. The crypto lands in your post-quantum account.
Optional Visa card linked to your wallet. Top up, transfer, withdraw, or spend at any merchant. A balance-trends chart tracks where the money goes, and the receipt lands in your activity feed.
Pick a pair, see the rate and the route in plain numbers, and confirm. The cold wallet co-signs by QR if you choose; the private key never leaves the device. Hybrid signature lands on chain.
A utility token, fairly launched with no team allocation. Half of all wallet fee revenue flows back to holders and stakers, half funds development. Full mechanics in the whitepaper.
Half of every fee the wallet earns flows back to the community of $QRYPT holders and stakers. The mechanism is finalized at launch.
The other half funds development, infrastructure, audits, and the cold wallet program. The product pays for the product.
Pay for QRYPT.COLD with $QRYPT to take a price cut off the hardware.
Hold $QRYPT to reduce fees on transactions sent through Qrypt apps. Discount scales with balance.
We did not start with a token. We started with cryptography. Then we made it portable. Then we made it daily.
