The Anansi wallet is a user-facing application built on top of our ERC-4337 implementation. It provides a secure and intuitive interface for users to manage their crypto assets.

1. User creates a new wallet using a secure passkey login (no mnemonics needed).
2. Each smart account is bound to a unique name which is registered on our smart contracts.
3. User interacts with the Anansi wallet interface to send and receive crypto on the Botanix blockchain.
4. Transactions are processed through our ERC-4337 implementation on Botanix, ensuring security and efficiency.

• Secure passkey login eliminates the need for managing private keys.
• Gas-free transactions on the Botanix testnet (testnet).
• Innovative implementation of ERC-4337 on the Botanix blockchain.
• Multi-chain support planned for future iterations.
• Simple Name Service to facilitate crypto transactions
• Recover smart account (Google OAuth 2.0)
• Modern and minimalistic user interface.
