• Savings automatically locked until the child turns 18
• Based on the child's birthdate provided during setup
• Parental override option for early withdrawals in case of emergencies

1. Intelligent Fund Management:

• Automatic conversion of any received cryptocurrency to USDC stablecoin
• Protection against local currency devaluation
• Easy deposits via QR codes and shareable payment links

1. Customizable Saving Goals:

• Create multiple savings objectives (e.g., "New Bike", "College Fund")
• Smart allocation of incoming funds across different goals

How Piggy Wallet is Made:

Core Technologies:

1. ERC-7579 Safe Smart Accounts: Provides the framework for our modular Smart Wallet
2. Module Kit by Rhinestone: Enables us to develop custom features like time-locks and auto token conversions.
3. Solidity: Smart Contracts.
4. React.js & Next.js & Tailwind.css & wagmi: Frontend.
5. Uniswap V4 Pool Manager: For swaps made through our token conversion module.
6. OpenAI GPT & VoiceFlow: Drives our AI-powered financial education bot.
7. Pimlico Paymaster: Enables gasless transactions for improved user experience.

Architecture:

1. Implementations of ERC4337:

• Extending Base Smart Wallet
• ERC-7579 Safe Smart Accounts

1. Time-Lock of Savings:

• Utilizes Module Kit by Rhinestone to implement time-locking mechanism
• For both implementations, multi-ownership is required
• 1 owner is designated as a “child” owner, which is unable to send any UserOperation until timelock has passed
• Timelock created based on child's birthdate
• Enables parental override functionality for emergency withdrawals

1. Swap to USDC:

• Integrates Uniswap V4 Pool Manager for efficient, decentralized token swaps
• Requires external transactions to be called into the Smart Wallet, ensures that fees are abstracted away from user

1. Savings Goals Setup:

• Creation and management of multiple savings objectives enabled through Safe Smart Account metadata

1. Tasks Bounties Setup:

• Another custom module powered by Module Kit by Rhinestone
• Enables parents to create tasks and automatically distribute rewards upon completion

1. Savings Tracking:

• Use USDC balance of Smart Account

1. AI Financial Advisor:

• Leverages OpenAI's GPT model for natural language processing and financial advice generation
• Integrates VoiceFlow for conversational UI and multi-modal interactions
• Custom prompt engineering to adjust complexity based on child's age

1. Gasless Fee Payments:

• Pimlico Paymaster for sponsoring gas fees
• Abstracts away gas complexities, improving UX for crypto newcomers 
 Frontend Implementation:
• permissionless.js used to create new Safe Smart Wallet

Notable Innovations:

1. No-code Smart Wallet Creation: By creating our own plugins and allowing parents to choose which ones to use for their child, we have essentially created a no-code platform to design your own Smart Wallet.
2. Age-Adaptive AI Bot: Our integration of OpenAI and VoiceFlow creates a unique, age-appropriate financial education experience, adjusting complexity based on the child's age stored in the smart account.
3. Seamless Token Management: The combination of Uniswap V4 Pool Manager and our custom swap module ensures that users always have their funds in stable USDC, protecting against volatility.
4. Frictionless User Experience: By utilizing Base Smart Wallet for account creation and Pimlico Paymaster for gas fees, we've created an onboarding and usage experience that feels as simple as using a traditional app. All blockchain interactions are abstracted away.

Challenges and Solutions:

1. Adding Features to Smart Wallets: Ran into many issues (unhelpful RPC errors, lack of documentation) deploying a custom Base Smart Wallet, and decided to switch to Safe Smart Wallets.
2. Uniswap v4 integration: Lack of public documentation and examples were outdated. Fortunately, there were employees readily available to help.
