How can we help you?

SSP Wallet is a true 2-of-2 multisignature system consisting of two components: SSP Wallet (browser extension) and SSP Key (mobile 2FA app). Both devices are required to authorize transactions, providing unmatched security for your crypto assets across 15+ blockchains.

You can install SSP Wallet as a Chrome extension from the Chrome Web Store. Visit our download page and follow our comprehensive setup guide for step-by-step instructions.

Yes, SSP Wallet is completely free to download and use. We don't charge any fees for the wallet itself, though you'll still pay network transaction fees when making blockchain transactions.

SSP Wallet supports 15+ blockchains including Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Zcash (ZEC), Ravencoin (RVN), Dogecoin (DOGE), Bitcoin Cash (BCH), Flux (FLUX), Polygon (MATIC), BSC, Avalanche (AVAX), and Base. For EVM-compatible chains, we support all ERC-20 tokens and you can import your own custom token lists. Solana support is coming soon.

For a comprehensive and up-to-date list of all natively supported chains and tokens, please refer to our official SSP Asset Spreadsheet. This spreadsheet is regularly updated with new additions and contains detailed information about each supported asset.

Yes! SSP Wallet features full WalletConnect v2 (Reown) integration, allowing you to connect to thousands of decentralized applications across all supported EVM chains. You can use DeFi protocols, NFT marketplaces, and other dApps while maintaining the security of the 2-of-2 multisignature system.

FluxNodes are nodes in the Flux network that help secure and maintain the blockchain. With SSP Wallet, you can easily set up and manage Fluxnodes, monitor their performance, and claim rewards directly through the wallet interface. Fluxnodes require a collateral amount of FLUX tokens and provide passive income through network rewards.

Yes! SSP Wallet supports fiat onboarding and offboarding through integrated partners. You can buy cryptocurrencies directly with your credit card, bank transfer, or other payment methods, and sell your crypto back to fiat currency. This feature is available in supported regions and requires KYC verification.

Yes, SSP Wallet includes built-in crypto swap functionality. You can easily exchange one cryptocurrency for another across supported blockchains through our integrated swap partners. The swap feature provides competitive rates and executes swaps securely while maintaining your private keys.

Yes! SSP Wallet supports CSV export of your transaction history. You can export detailed transaction records for accounting, tax purposes, or personal record-keeping. The CSV export includes transaction dates, amounts, addresses, fees, and other relevant details for each supported blockchain.

We encourage users to reach out to our support team or contribute directly on our GitHub repository to request new cryptocurrency support. We evaluate each request based on community demand, technical feasibility, and security considerations.

Good news! We are actively working on expanding SSP Wallet to mobile platforms. Currently, SSP Wallet consists of a browser extension (SSP Wallet) and a mobile 2FA app (SSP Key). A full mobile wallet experience is in development.

Yes, you can use SSP Wallet on multiple devices. To set up on a new device, you'll need to restore your wallet and key using the corresponding seed phrases. Each device requires proper setup and synchronization.

SSP Wallet uses multi-signature technology with mobile-integrated authentication, providing two-key protection. We use cutting-edge encryption and don't store any of your data - everything is stored locally and controlled by you.

SSP Key is a mobile app that holds the second private key required for the 2-of-2 multisignature system. Every transaction must be signed by both your browser extension AND your mobile device. This ensures your funds remain secure even if one device is compromised. SSP Key is available for iOS 15.1+ and Android 7+.

Yes, you can recover your wallet using your seed phrase. Both your wallet and key have separate seed phrases that should be stored securely offline. Never share your seed phrases with anyone.

No, SSP Wallet is committed to not storing any data information. Your private keys, transaction history, and personal data remain entirely under your control and are stored locally on your devices.

Deterministic builds ensure that identical source code produces identical binary outputs. SSP Wallet uses Docker-based deterministic builds that enable anyone to independently verify that the distributed extension matches exactly what was built from the published source code. This eliminates potential supply chain attacks and provides cryptographic proof of build integrity.

To verify SSP Wallet builds: 1) Download the release files (Chrome/Firefox zips, SHA256SUMS, SHA256SUMS.asc) from GitHub releases. 2) Import our public key from OpenPGP keyserver. 3) Verify GPG signature: gpg --verify SHA256SUMS.asc SHA256SUMS. 4) Verify hashes: sha256sum -c SHA256SUMS. 5) Optionally reproduce the build: git checkout [version] && npm run build:deterministic.

All SSP Wallet releases are cryptographically signed by [email protected] using GPG signatures. Our public key is available on OpenPGP keyserver for verification. The deterministic build process includes Docker-based isolated environments and comprehensive checksums (SHA256SUMS) that are also GPG-signed to ensure authenticity and integrity.

SSP Wallet supports Google Chrome, Brave, Firefox, and other Chromium-based browsers. You can download the Chrome Web Store version for Chromium browsers or the Firefox version directly from our GitHub releases.

Make sure both devices are connected to the internet, the QR code is clearly visible, and you're using the latest versions of both the browser extension and mobile app. Try restarting both applications if sync fails.

Blockchain transactions can sometimes take time depending on network congestion. Check the transaction status on a blockchain explorer. If using Ethereum, you may need to increase gas fees for faster confirmation.

Browser extensions typically update automatically. You can manually check for updates in your browser's extension management page. For the mobile app, check your device's app store for updates.

SSP Relay is an open-source relay service that acts as a bridge between your SSP Wallet and SSP Key. It provides market information, fee data, enables transaction synchronization, and delivers push notifications. The relay enhances the user experience while maintaining security.

Yes, SSP Wallet fully supports Replace-By-Fee (RBF) functionality. You can modify transaction fees and even change recipients after broadcasting a transaction, giving you flexibility in managing your transactions on the blockchain.

SSP Wallet has zero fees - we don't charge anything for using the wallet. You only pay the standard blockchain network fees that go directly to miners/validators for processing your transactions. The wallet includes automatic fee selection to optimize your transaction costs.

Some transactions may fail due to blockchain size restrictions and UTXO complexity. When you have many small inputs, the transaction size can exceed network limits. In such cases, you may need to consolidate your UTXOs or break the transaction into smaller parts.

Yes, due to device-specific encryption, you must restore both your wallet and key when changing devices or making significant system changes. Keep your seed phrases secure and accessible for this process.
