Overview
Development of various DeFi protocols including AMM DEX, Yield Farming, and Staking systems across Ethereum and Solana ecosystems.
Key Features
AMM DEX (Automated Market Maker)
- Implemented constant product formula (
x * y = k) for token swaps - Built multi-hop routing for optimal trade execution across liquidity pools
- Integrated slippage protection and deadline parameters for user safety
- Deployed factory/router pattern following Uniswap V2 architecture
Yield Farming Mechanism
- Designed reward distribution using per-second accrual model
- Implemented multiplier boosts for long-term stakers
- Built harvest and compound functions with gas-optimized batch operations
Token Staking System
- Created flexible and locked staking vaults with configurable lock periods
- Implemented penalty mechanisms for early withdrawal
- Built governance weight calculation based on stake duration
Liquidity Pool Management
- Developed LP token minting/burning with proportional share tracking
- Implemented fee collection and distribution to liquidity providers
- Built emergency withdrawal functions with timelock governance
Technologies
- Smart Contracts: Solidity (EVM), Rust + Anchor (Solana)
- Testing: Hardhat, Foundry, Anchor Test Suite
- Blockchain SDK: Web3.js, Ethers.js, @solana/web3.js
- Security: OpenZeppelin contracts, custom reentrancy guards
Achievements
Successfully deployed multiple DeFi protocols with comprehensive test coverage and security-first design. All contracts passed internal security review with no critical vulnerabilities found.
