Gemini Wallet
Gemini's self-custody smart-contract wallet with passkey login and gas sponsorship across Ethereum and major L2s.
What is Gemini Wallet?
Gemini Wallet is a passkey-based smart-contract wallet built on the Biconomy Nexus stack, operated separately from the Gemini exchange. Users sign in with FaceID or TouchID without a seed phrase, send and receive across Ethereum, Arbitrum, Base, Optimism, and Polygon, and use sponsored gas across DeFi apps through the Gemini Onchain App. An MIT-licensed SDK lets developers embed the wallet in their own apps.
