Smart Contracts

The smart contract system is the foundation of GO Swap, handling all on-chain operations for token swaps and liquidity management.

Core Contracts​

LiquidityPool​

The primary contract that manages reserves, swaps, and liquidity provisioning.

Responsibilities:

  • Maintain token reserves (x and y)
  • Execute swaps using constant product formula
  • Manage liquidity additions and removals
  • Emit events for indexer tracking
  • Calculate and distribute fees

Key Functions:

function swap(uint256 amountIn, address tokenIn, address tokenOut)
function addLiquidity(uint256 amountA, uint256 amountB)
function removeLiquidity(uint256 lpTokens)
function getReserves() returns (uint256, uint256)

Factory (Future)​

Creates new pools for token pairs permissionlessly.

Responsibilities:

  • Deploy new pool contracts
  • Track all deployed pools
  • Prevent duplicate pools for same pairs
  • Manage pool creation fees

Router (Future)​

Provides optimized routing for multi-hop swaps.

Responsibilities:

  • Calculate optimal swap paths
  • Execute multi-hop transactions
  • Minimize slippage across routes
  • Handle deadline and slippage protection

Token GO​

Native utility token of the ecosystem.

Responsibilities:

  • Governance voting (future)
  • Fee incentives and rewards
  • Ecosystem utility functions
  • Liquidity mining distributions

Contract Standards​

All contracts follow:

✅ EVM Compatibility - Works on all EVM-compatible chains

✅ ERC-20 Standard - Full token standard compliance

✅ Security Best Practices - Reentrancy guards, safe math

✅ Gas Optimization - Efficient execution patterns

✅ Event Emission - Comprehensive logging for transparency

Deployment​

All contracts are deployed on Binance Smart Chain (BSC) initially, with future multi-chain deployments planned.

Testnet Deployment: BSC Testnet (for testing and audits)

Mainnet Deployment: BSC Mainnet (production)

Security Model​

GO Swap follows a non-custodial security design:

🔒 Users keep control of private keys

🔒 Smart contracts are immutable after deployment

🔒 No centralized fund custody

🔒 Transparent on-chain execution

Security Measures:

  • Contract audits (planned)
  • Rate-limited RPC usage
  • Safe token approval flows
  • Replay protection via blockchain finality
