Contract Architecture

GweAI’s smart contract ecosystem is deployed on Base Sepolia (Chain ID: 84532) and consists of four main components that work together to provide secure DeFi functionality.

​
Verified Contracts

All contract addresses are hardcoded and verified on-chain to prevent frontend manipulation attacks:

Router Contract

Main trading interface for token swaps0x49B538646dc51f1b8c533113113A7dE05fBC2218

Liquidity Pool

Holds all protocol liquidity0xDEEd6a61940bD4162f9955aeBb477C3bDABf6078

Vault Staking

Time-locked staking with yield generation0xB156a66521BCB5A903daA42879A3e562E402Fa41

Subscription

Security Features

​
Address Verification

All contract addresses are validated using multiple security layers: 
import { getVerifiedContract, validateTransaction } from '@/config/contracts';

// Get verified contract address - throws error if modified
const routerAddress = getVerifiedContract('ROUTER');

// Validate before transaction
const validation = await validateTransaction({
  contractAddress: routerAddress,
  contractType: 'ROUTER',
  userAddress: '0x...',
});

if (!validation.valid) {
  throw new Error(validation.error);
}

​
Token Whitelist

Only whitelisted tokens can be used in transactions: 
import { isVerifiedToken } from '@/config/contracts';

if (!isVerifiedToken(tokenAddress)) {
  throw new Error('Token not in whitelist');
}

​
On-Chain Verification

Contracts are verified by checking bytecode exists on-chain: 
import { verifyContractOnChain } from '@/config/contracts';

const isValid = await verifyContractOnChain(contractAddress);
// Returns true if contract has valid bytecode
Contract addresses are immutable in the codebase and cannot be modified through environment variables. Any attempt to use unverified addresses will trigger security events and fail validation.

​
Function Signatures

Verified function selectors for transaction validation:

buy(address,uint256,uint256)0xa59ac6ddRouter
sell(address,uint256,uint256)0x6a272462Router

purchasePlan(uint8)0x98693010Subscription
transfer(address,uint256)0xa9059cbbERC20
approve(address,uint256)0x095ea7b3ERC20

​
Treasury Wallet

Protocol treasury and admin address: 
0x39c0b97A8F2194fcd7396296F7697a84dd81077A
The treasury receives:
  • Protocol fees from swaps
  • Early withdrawal penalties from vault staking
  • Subscription payments

​
Security Monitoring

All contract interactions are logged for security monitoring: 
import { logSecurityEvent } from '@/config/contracts';

logSecurityEvent({
  type: 'CONTRACT_CALL',
  details: 'Swap transaction initiated',
  address: routerAddress,
});
Event types:
  • CONTRACT_CALL - Contract function invoked
  • ADDRESS_VALIDATION - Address verified
  • SIGNATURE_CHECK - Function signature validated
  • ERROR - Security violation detected
