Import Your Private Keys - MetaMask, Trust Wallet, Coinbase Wallet - Type in your (hardware wallet( seed phrases - Auto-detects any format 2. Quantum-Safe Encryption - X-Wing / ML-KEM-768 (same as iOS 26 uses) - Encrypted on your device - Q-Ledger never sees your keys 3. Store Forever on Arweave - One-time payment, permanent storage - Thousands of independent global nodes - Survives even if Q-Ledger shuts down 4. Recover Anytime - Decrypt on iOS with Face ID - Pro: Platform-independent recovery --- WHY Q-LEDGER * One-time fee vs. perpetual subscriptions * Only quantum-safe crypto backup solution * Disaster-proof: no physical backup to lose * Zero custodians: verifiable security * Platform independence (Pro version) * Open encryption format * Inheritance ready * No account required --- PLANS Free version includes 1 wallet backup with quantum-safe encryption and permanent storage. Wallet bundles available for backing up multiple keys. Pro upgrade unlocks platform-independent recovery, multi-device iOS access, and GitHub recovery scripts for any platform. --- SUPPORTED FORMATS BIP39 seed phrases (12-24 words), raw hex, WIF, extended keys (BIP32/BIP44), JSON keystores (MetaMask), JWK (Arweave), QR codes, documents up to 8KB. Auto-detect handles any format. --- SECURITY Your encrypted backup is publicly visible on Arweave but unreadable without your keys. This eliminates private channels where data could be intercepted. Q-Ledger never receives your encryption keys—they're stored only in iOS Keychain. Traditional encryption (AES, RSA) will be broken by quantum computers. Q-Ledger uses X-Wing ML-KEM-768—the same post-quantum algorithm in iOS 26—protecting against future threats. If quantum computers break Q-Ledger's encryption, they've already broken blockchain signatures. Your backup is no more vulnerable than the blockchain itself. --- WHAT IF Q-LEDGER SHUTS DOWN? Your wallets remain accessible. All data is on Arweave's decentralized network, not Q-Ledger servers. Standard users keep using the app. Pro users can decrypt on any platform using public GitHub recovery scripts. --- MULTI-DEVICE ACCESS Encryption keys sync automatically via iCloud Keychain. Sign in to a new iPhone with the same Apple ID—all wallets become accessible immediately. Pro users can also manually export for non-Apple devices. --- Your keys, your crypto, your backup. Forever. Download free. Back up your first wallet in 30 seconds. License: https://www.q-ledger.app/terms-and-conditions

Built for the agentic age, AC2 helps developers, enterprises, and security-conscious users establish cryptographic control over AI-assisted actions. AC2 Wallet is the reference implementation for the AC2 Protocol, enabling secure, hardware-bound approvals for AI agent workflows. Using FIDO2 passkeys and non-custodial cryptographic signatures, AC2 Wallet allows you to authorize actions without exposing your private keys. Every approval generates cryptographically verifiable proof of intent, creating an auditable record of who approved what and when. With AC2, you can: - Prove that a human reviewed and approved code changes for an agent to merge - Prove that a human reviewed and approved communications for an agent to send, like client emails or social media posts - Validate agents to make direct x402 payments, without exposing your private wallet or account information - Enable agents to log in to platforms and continue workflows using a signed authorization from the user, so the underlying credentials stay on the user's device. AC2 is a self-custodial Algorand wallet. You — and only you — hold your seed phrase, your keys, and your crypto-assets on your own device. Pera Wallet, Lda does not hold, custody, or have access to your seed phrase, your keys, or your crypto-assets, and cannot recover them on your behalf. If you lose your device or your recovery phrase, your access to anything you have linked through AC2 may be permanently lost. Your recovery phrase is the only way to restore access to your wallet. Pera cannot recover it for you. If you lose it, your crypto-assets and account associations are lost permanently. Do not share it with anyone, including anyone claiming to be Pera support. Crypto-asset transactions are irreversible once confirmed on the Algorand network. Crypto-assets are volatile, may lose value, and may become illiquid or unavailable. You are responsible for any tax or other legal obligations arising from your use of crypto-assets.
