​
Overview

Request Network operates through a set of smart contracts deployed across multiple blockchain networks. These contracts handle payment processing, fee collection, and request lifecycle management. This page provides contract addresses, ABIs, and integration details for developers.

​
Core Contract Architecture

Request Manager

Core Protocol ContractPurpose: Request creation, updates, and lifecycle management Features:
  • Request creation and validation
  • Metadata storage and retrieval
  • Request status management
  • Event emission for indexing

Payment Processor

Payment Execution ContractPurpose: Handle actual payment processing Features:
  • Multi-currency payment support
  • Fee collection and distribution
  • Payment verification
  • Cross-chain payment routing

Fee Manager

Fee Collection ContractPurpose: Platform and integration fee management Features:
  • Configurable fee structures
  • Multi-party fee distribution
  • Fee rate management
  • Revenue sharing automation

Currency Registry

Supported Currency ContractPurpose: Manage supported currencies and tokens Features:
  • Currency whitelist management
  • Token metadata storage
  • Price oracle integration
  • Currency validation

Integration Examples

const Web3 = require('web3');
const web3 = new Web3('https://polygon-rpc.com');

// Contract instance
const requestManager = new web3.eth.Contract(
  REQUEST_MANAGER_ABI,
  '0xpoly...001'
);

// Create a payment request
async function createRequest(payeeAddress, payerAddress, amount, tokenAddress) {
  const requestData = {
    payee: payeeAddress,
    payer: payerAddress,
    expectedAmount: web3.utils.toWei(amount.toString(), 'ether'),
    currency: tokenAddress,
    deadline: Math.floor(Date.now() / 1000) + 86400 // 24 hours
  };
  
  const tx = await requestManager.methods
    .createRequest(requestData)
    .send({ from: payeeAddress });
    
  return tx.events.RequestCreated.returnValues.requestId;
}

Gas Usage Estimates

​
Transaction Gas Costs

Gas Usage for Request Management:
OperationEstimated GasCost on PolygonCost on Ethereum
Create Request150,000$0.01$3-30
Update Request80,000$0.005$2-20
Cancel Request60,000$0.003$1-15
Optimization Tips:
  • Batch multiple operations when possible
  • Use Layer 2 networks for frequent operations
  • Optimize metadata to reduce gas usage
