Deploy

---

We used Hardhat for deployment. To learn more: Hardhat

Contracts have been deployed on both mainnet and testnet:

• Amoy and mainnet for Polygon
• Sepolia and mainnet for Ethereum

After cloning, try:

💡Tip: Run npm install to add Hardhat locally

npx hardhat deploy

For deployment on testnet or mainnet:

npx hardhat deploy --network <network of choice>

---

Tests

---

Tests had to be done in two ways to optimize costs:

• Tests done locally that don't require UserOp
• Tests on UserOp have been done with Alchemy

💡Tip: For this section you need API keys from either Alchemy or Biconomy. We recommend Alchemy.

After getting your API keys:

npx hardhat test

Features

Here we cover the exciting features built by Shakesco.

1. Buy, Send and Receive/Request - We have the basic features of every EOA wallet built into our smart contract wallets.

2. Recurring Payments on Ethereum - We're excited about this! You can now perform auto-payments on Ethereum. Check out our documentation on how it works and how you can start receiving auto-payments.

3. Private Transactions - Credit to Umbra. We use their registry to register keys so that businesses and users can perform private transactions. Check out our docs.

4. Silent Payments - Bitcoin Silent Payments implementation for enhanced privacy on Bitcoin transactions. See our Silent Payments guide.

5. Send to Many - ERC-4337 enables the executeBatch function. You can send money to multiple people, or even privately send to multiple users at once.

6. Loyalty Program - Businesses can deploy their own ERC-20 loyalty tokens with advanced features:

   • Token Creation - Launch custom branded tokens
   • Off-chain Management - Customers don't need crypto wallets
   • Staking - Let customers lock tokens to earn rewards
   • Vesting - Distribute tokens gradually with cliff periods
   • Cashback Programs - Automatic rewards when spending thresholds are reached
   • Happy Hours - Limited-time promotions with multiplied rewards
   • Tier Systems - Bronze, Silver, Gold tiers based on holdings
   • Daily Caps - Control maximum daily earnings
   • Voting Power - Token-weighted governance

   See our Loyalty Program documentation.

7. Name Service - We developed a built-in name service that enables anyone to register for free. It's a demand-based system rather than subscription-based. You can bid on usernames, preserve them, etc.

8. Personal and Business Account Integration - Open a personal wallet and then a business wallet and receive value in both. Seamlessly switch between personal and business contexts.

9. Payment Links - Create shareable payment links to accept one-time or recurring payments. Perfect for invoices, donations, or selling products.

10. Checkout Integration - Integrate crypto checkout into your website or app with simple APIs.

11. Multi-Party Computation (MPC) Security - Keys are distributed across multiple parties, ensuring no single point of failure. Enterprise-grade wallet security.

12. Account Abstraction (ERC-4337) - Gasless transactions, batch operations, and social recovery. Users don't need to manage gas fees or seed phrases.
