Post Quantum Secure Wallet

Description

Secure browser wallet with post-quantum cryptography support for blockchain transactions Post Quantum Secure Wallet is a browser wallet that signs transactions with post-quantum cryptography, so your accounts stay secure even against an attacker with a quantum computer. NEW IN 1.1.0 The interface has been rebuilt from the ground up: a cleaner wallet list, a clearer transaction confirmation screen, real light and dark themes that follow your system setting, and a simpler layout that puts send and receive one tap from your balance. TWO KINDS OF ACCOUNT • ECDSA accounts — work with Ethereum, BNB Chain, Polygon, Arbitrum and other EVM networks, the same as any standard wallet • Post-quantum accounts — signed with ML-DSA-44, the signature scheme standardised by NIST in FIPS 204 • Both live side by side in one extension, on separate tabs • Import an existing account from its private key WHAT YOU CAN DO • Create as many accounts of either type as you need • Send and receive, with a QR code for your address • Add SCI-20 tokens by contract address • Keep a contact book of addresses you use often • Review full transaction history, including gas and confirmations • Add custom EVM networks by RPC URL • Switch between light and dark themes HOW YOUR KEYS ARE HELD • Private keys are encrypted with your master password and stored on this device • Nothing is sent to a server — there is no account, no sync, no cloud backup • No analytics, no tracking, no data collection of any kind • The wallet locks itself after a period of inactivity • Exporting a private key requires your password IMPORTANT — PLEASE READ Post-quantum accounts work only on SciChain. Do not send funds from Ethereum, BNB Chain or any other network to a post-quantum address: those funds cannot be recovered. Use an ECDSA account for every other network. There is no way to recover your master password. If you lose it, the accounts on this device cannot be opened again. Keep a copy somewhere safe. TRANSACTION FEE A 0.2% commission is applied to transactions. This funds continued development and is why the wallet carries no ads and collects no data. The exact amount is always shown on the confirmation screen before you approve anything. WHY POST-QUANTUM Today's signature schemes — ECDSA and RSA — rest on mathematics a sufficiently large quantum computer could break. Recorded transactions and long-lived keys are the assets most at risk, because they can be captured now and attacked later. ML-DSA-44 is built on lattice problems that no known quantum algorithm solves efficiently, and it is one of the schemes NIST standardised for exactly this reason. NETWORKS • SciChain — for both ECDSA and post-quantum accounts • Ethereum, BNB Chain, Polygon, Arbitrum — ECDSA accounts only • Any EVM network you add yourself by RPC URL PERMISSIONS • storage and unlimitedStorage — to keep your encrypted accounts on this device • Access to rpc.scimatic.net — to read balances and broadcast transactions Built by ZincirQ.
