NOVA is a free, open-source crypto wallet supporting Ethereum, Polygon, BSC, Avalanche, and Solana. Your keys, your crypto, your privacy.
Different chains, different wallets, different seed phrases. Each one is another point of failure, another password to remember, another interface to learn. It's fragmented, frustrating, and risky.
One wallet. One seed phrase. Five blockchains. NOVA gives you a single interface to manage all your crypto assets with bank-grade encryption and zero compromise on security or privacy.
See what builders and traders are saying about NOVA.
"Switched from MetaMask and never looked back. Managing positions across Ethereum and Polygon from one wallet saves me hours every week. The gas estimation alone is worth it."
"We recommend NOVA to every new team member. Open source, fully auditable, and the UX is cleaner than anything we have tried. The multi-chain support is exactly what our team needed."
"Finally a wallet that treats security seriously. BIP39 compliance, AES-GCM encryption, and zero cloud dependency. I reviewed the codebase myself - it is solid engineering."
Trade, hold, and transact across five major blockchains from a single wallet.

You do. NOVA is non-custodial. Your private keys are generated and stored entirely on your device. They are encrypted with AES-GCM and never transmitted anywhere. No server ever has access to your keys.
You can restore your wallet using your 12-word recovery phrase. This is why it is critical to write down and securely store your seed phrase during wallet creation. Without it, your funds cannot be recovered.
NOVA currently supports Ethereum, Polygon, BNB Chain (BSC), Avalanche (C-Chain), and Solana. More chains are planned for future releases. Supporter tier donors get early access to new chain integrations.
