DeFi Smart Contract Development Staking, Liquidity Pools & Yield Farming
Hi, I'm Qalb a DeFi developer with 5+ years of experience. I built production DeFi systems at Degen Market including high-performance liquidity pools, staking engines, and reward distribution contracts that processed real funds.
WHAT I BUILD:
- Staking Systems:
- Single & multi-token staking pools with APY/APR rewards
- Lock-up periods with early withdrawal penalties
- Auto-compound staking + LP token staking
- Masterchef-style multi-pool reward contracts
Liquidity & AMM:
- Uniswap V2/V3-compatible liquidity pools
- Liquidity mining + LP staking reward engines
- Token vesting + cliff release schedules
- DAO governance contracts (ERC-20 token voting)
Reward Engines:
- Multi-token yield farming
- Reflection tokens (auto-redistribute to holders)
- Dividend distribution contracts
- Referral reward systems
SECURITY STANDARDS:
- OpenZeppelin (re-entrancy guards, access control, Ownable)
- Full Hardhat + Foundry test suites (unit + integration)
- Gas optimization + deployment gas report
- Testnet + mainnet deployment + block explorer verification
All DeFi projects start with a free consultation message me before ordering.

FAQ
Are the contracts audited?
I write audit-ready code using OpenZeppelin standards with full test suites. For a formal third-party audit (CertiK, Hacken, etc.), that's a separate engagement, I can recommend reputable firms.
Can you fork Uniswap or PancakeSwap?
Yes, I can fork and customize Uniswap V2/V3, PancakeSwap, or other open-source AMMs. This typically falls in the Premium tier. Contact me to discuss specifics.
What information do I need to provide?
Your token contracts (or I can build them), desired APY rates, lock-up rules, reward distribution logic, and target chain. I'll send a detailed requirements form after ordering.
