Introduction

1Wallet is a gasless web3 wallet that utilizes the Safe {WALLET} and the Safe AA SDK, enabling users to perform various actions such as swaps on platforms like 1inch. The wallet's core feature is the utilization of WebAuthn for authentication, allowing users to authenticate requests using FaceID or TouchID without the need to store any private keys or seed phrases.

Key Features

• Gasless Transactions: 1Wallet enables gasless transactions by relaying calldata to the entrypoint for execution on the Safe wallet, saving users from paying gas fees for their transactions.

• Secure Authentication: WebAuthn is used for authentication, ensuring a high level of security as the user's private keys are stored in the device's secure enclave.

• Swaps on 1inch: The demo showcases the capability of the wallet by enabling users to place swaps on 1inch in a gasless fashion.

• Self-Custodial and Trustless: 1Wallet allows users to manage their assets and generate orders via their devices in a self-custodial and trustless manner.
