- Creating API Keys : Create a API key to kickstart your Smart Wallet journey.
- Sponsoring gas for users : A third-party sponsor (Gas Tank) covers the gas fees, allowing users to transact without holding any native tokens.
- Allowing users to pay gas with their ERC20 tokens : Users can pay gas fees using supported ERC-20 tokens, eliminating the need to acquire native tokens.
- Allowing users to pay gas with their Native tokens : Users cover gas fees directly using native tokens like ETH—the default and most widely supported method.
- Using Dynamic/Privy as wallet providers with React SDK : Users can interact with applications using email, phone, or social logins through wallet providers like Dynamic and Privy, enjoying full dApp functionality with a seamless Web2-like experience.
- Estimating Gas before sending transactions on-chain : Developers can simulate transactions to estimate gas costs in advance, improving reliability and user experience.
