Absynth

This project is a smart contract wallet built with Account Abstraction (ERC-4337), offering a friendly and intuitive UI for effortless onboarding and daily use. Users can authenticate using passkeys (WebAuthn), eliminating the need to manage private keys. Gasless transactions are enabled through the Paymaster, and cross-chain functionality allows seamless interactions across multiple EVM networks.

The wallet is designed to offer a comprehensive, all-in-one wallet management experience, empowering users to interact freely across chains, delivering flexibility in the Web3 ecosystem.

Our development process is divided into two parts: the front-end integrates various SDKs, while contract development requires customized on-chain functionalities. We aim to implement functionality with the minimum effort required, prioritizing the integration of SDKs or APIs to achieve the necessary features.

On the front-end side, we integrate the SDKs of Circle and Pimlico to provide features such as passkey, bundler, paymaster, and etc. However, when using Circle's Wallet Infra and Circle CCTPv2, we discovered that the supported chains do not overlap at all. To bridge this gap and ensure broader coverage, we integrated Pimlico’s wallet infrastructure as a complementary solution, mixing usage depending on chain support.

On the contract development, we use Circle’s CCTP v2 to build a custom hook for cross-chain deposit and withdrawal into an ERC-4626 vault and cross-chain payment, allowing users to hold shares across different chains. This enables a seamless, abstracted experience for managing yield-bearing assets in a multi-chain environment.
