InitPay

Multi-Chain Crypto Payroll for Global Teams on Initia

📋 Project Overview

InitPay is a comprehensive payroll platform that enables companies to pay employees across EVM, Move, and Wasm chains in a single transaction. Built on Initia's interwoven architecture, it eliminates bridge risks while providing advanced DeFi features for modern workforce management.

What It Does

Batch Payments - Pay 100+ employees in one transaction with 1% fee
Payment Streaming - Real-time salary streaming, employees earn per second
Lucky Pool Lottery - Team bonus pools with provably fair winner selection
Salary Staking - Lock salary to earn 5-30% APY based on lock period
Salary NFTs - Tokenize future earnings for instant liquidity
P2P Salary Swaps - Trade shifts and salary with colleagues
Intent-Based Routing - Natural language payment processing

Key Innovation

Unlike traditional payroll systems (single-chain, slow, expensive), InitPay uses Initia's interwoven architecture for true multi-chain payments without bridge risks.

Traditional Payroll:  Company → Bridge → Wait → Employee (risky, slow)
With InitPay:         Company → Initia → Instant → Employee (safe, fast)

No bridge hacks. No waiting. No complexity.

🌐 Why This Matters for Initia

The Multi-Chain Payroll Problem

The x402 protocol and Initia's interwoven architecture enable seamless cross-chain operations. Payroll is the perfect use case to showcase this capability.

What We Bring to Initia

Benefit	Impact
Showcases Interwoven Power	First real-world payroll use case demonstrating cross-VM payments
Drives Enterprise Adoption	Companies need payroll - massive TAM with viral growth potential
Network Effects	More employees = more chains = more liquidity
DeFi Integration	Combines payments with staking, NFTs, streaming - full ecosystem showcase

Market Need

$500B global payroll market
10M+ crypto-native companies by 2027
3-5% wire transfer fees (we charge 1%)
3-5 days settlement time (we're instant)
All of these need multi-chain support that can't be bridged safely

Option 2: Direct Contract Interaction

Execute Batch Payment

// Solidity - Pay multiple employees
interface IPayrollDistributor {
    function distributePayroll(
        address[] calldata recipients,
        uint256[] calldata amounts
    ) external payable;
}

IPayrollDistributor payroll = IPayrollDistributor(0xD8B9D7C3b20e2981004dDDb702e41c9A552C5f88);

address[] memory employees = new address[](3);
employees[0] = 0xAlice...;
employees[1] = 0xBob...;
employees[2] = 0xCharlie...;

uint256[] memory salaries = new uint256[](3);
salaries[0] = 1000 ether; // 1000 INIT
salaries[1] = 1500 ether;
salaries[2] = 2000 ether;

payroll.distributePayroll{value: 4500 ether}(employees, salaries);

Create Payment Stream

// Create a stream that pays 1000 INIT over 30 days
interface IPayrollStreaming {
    function createStream(
        address employee,
        uint256 duration,
        string calldata targetChain
    ) external payable returns (bytes32 streamId);
}

IPayrollStreaming streaming = IPayrollStreaming(0x0787e6ebF537664b5a0E8a627f12c4861d54ED44);

bytes32 streamId = streaming.createStream{value: 1000 ether}(
    employeeAddress,
    30 days,
    "initia-evm"
);

// Employee can withdraw earned amount anytime
streaming.withdraw(streamId);

Stake Salary for APY

// Stake 100 INIT for 90 days to earn 12% APY
interface ISalaryStaking {
    function stake(uint256 lockPeriod) external payable;
}

ISalaryStaking staking = ISalaryStaking(0x5F06943c9E0284a8D6C06963f8201BF8f3700Baf);

staking.stake{value: 100 ether}(90 days);

Option 3: JavaScript/TypeScript Integration

import { ethers } from 'ethers';

// Connect to contracts
const PAYROLL_ADDRESS = '0xD8B9D7C3b20e2981004dDDb702e41c9A552C5f88';
const PAYROLL_ABI = [
  'function distributePayroll(address[] recipients, uint256[] amounts) payable',
  'function depositFunds() payable',
];

const provider = new ethers.BrowserProvider(window.ethereum);
const signer = await provider.getSigner();
const payroll = new ethers.Contract(PAYROLL_ADDRESS, PAYROLL_ABI, signer);

// Batch payment
const recipients = ['0xAlice...', '0xBob...'];
const amounts = [
  ethers.parseEther('1000'),
  ethers.parseEther('1500')
];

const tx = await payroll.distributePayroll(recipients, amounts, {
  value: ethers.parseEther('2500')
});
await tx.wait();
console.log('Payroll distributed:', tx.hash);
