🚨 As the deployment of the HyperLane bridge is done on the cloud Kurtosis free plan, the cross-chain calls won't work after 2nd july 11.30 pm. Please refer to the demo video for more information. 🚨
Payroll Protocol is a confidential money distribution platform built on top of BASE, designed to provide confidentiality during the distribution of funds on-chain. By leveraging FHE cryptography and smart contracts, Payroll Protocol ensures the confidentiality, security, and efficiency of money distribution.
Payroll Protocol integrates BICONOMY AA SDK, BASE, and INCO FHEVM to enhance user experience while confidentially distributing money.
INCO FHEVM provides hidden states to store encrypted addresses that hold encrypted amounts on the INCO network, ensuring that all transactions are secure and confidential. This integration guarantees that money distribution details and recipient information remain confidential. It uses modified Hyperlane infrastructure to bridge these state values from BASE to INCO and vice versa.
- Encrypted USDC Distributions: Protects sensitive information with robust encryption methods.
- User-Friendly Interface: Simplifies the payroll process with one click, thanks to BICONOMY SDK.
- Stealth Hold: Users can hold stablecoins for an indefinite amount of time without revealing the amount.
- Underline Distribution: Users can completely hide their withdrawals by distributing the encrypted amount to different encrypted addresses on their behalf, providing an experience similar to Tornado Cash.
- Frontend: Next.js, Tailwind CSS
- Authentication & Wallets: Privy
- Backend & Smart Contracts: Node.js, Solidity
- Blockchain: BASE, INCO FHEVM
- Account Abstraction & Gasless Transactions: Biconomy
- Encryption: FHE schemes
- Connect your web3 wallet.
- Navigate to the distribution page.
- Enter the recipient addresses and amounts.
- Confirm the transaction to distribute funds confidentially.
