Introduction

ZeroWallet is an innovative project built for ETHOnline 2024, combining the power of omnichain transactions, automated savings, and secure account management. This next-gen wallet solution revolutionizes the way users manage their digital assets across multiple blockchains while promoting financial growth through seamless, gasless transactions and automated investments.

Key Features

• Omnichain transactions powered by LayerZero
• Automated investment strategies with DCA (Dollar-Cost Averaging)
• Secure onboarding with Safe smart accounts and passkey authentication

Omnichain Functionality

ZeroWallet leverages LayerZero's omnichain capabilities to enable smooth transactions across various blockchain ecosystems. This technology breaks down network silos, allowing users to transfer assets effortlessly between chains without worrying about gas fees or complex configurations. The use of ERC-4626 vaults and OFT (Omnichain Fungible Token) contracts ensures easy cross-chain fund management and withdrawals.

Automated Investment Strategies

The wallet includes a powerful Dollar-Cost Averaging (DCA) module that automates investments for users, making it easier to build a diversified crypto portfolio.

Secure Onboarding with Passkey

ZeroWallet prioritizes user security and simplicity with passkey authentication via WebAuthn 7579. This integration makes Safe smart account onboarding frictionless, enabling users to manage their assets securely without cumbersome wallet setups.

How It Works

• Users define their preferred investment strategy and frequency
• The system auto-invests stablecoins or other assets into yield-generating ERC-4626 vaults
• Assets can be withdrawn across any network, ensuring continuous access

Technical Implementation

ZeroWallet is built on top of Safe smart accounts and utilizes advanced technologies like LayerZero for chain abstraction and ERC-4337 for gas and account abstraction.
