Smart Contract Development for UAE Web3 Projects
Production-grade smart contracts in Solidity for EVM chains - Ethereum, Polygon, Base, Arbitrum and BNB Chain - covering ERC-20 tokens, ERC-721 and ERC-1155 NFTs, staking and vesting, escrow, DAO governance and bespoke protocol logic. I build on audited OpenZeppelin libraries rather than hand-rolling primitives, so access control, pausability and upgradeable proxy patterns follow battle-tested standards from day one. Chain selection is a deliberate decision: I recommend Base or Polygon when gas cost per user mint matters, Arbitrum for DeFi throughput, and Ethereum mainnet only where settlement assurance justifies the fees.
Every engagement ships with a full Hardhat or Foundry test suite targeting high coverage, static analysis with Slither, and gas optimisation of storage layout and call patterns to keep transaction costs down. Security is the default, not an upsell: each contract gets an internal review against the common vulnerability classes - reentrancy, integer overflow, unchecked external calls, access-control gaps and front-running exposure - and for high-value contracts I coordinate a third-party audit and help triage the findings. You receive deployment scripts, a source-verified contract on the block explorer (Etherscan, Basescan, Polygonscan) and clean documentation. Builds start at AED 8,000 for a standard token or NFT contract with tests and deployment; complex protocols and external audits are quoted higher in AED after spec.
This gig is the contract engineering itself, suited to UAE Web3 startups, tokenised-asset projects and exchanges. Regulatory licensing through Dubai's VARA or Abu Dhabi's ADGM is my separate compliance service, and full token-launch mechanics - tokenomics, SPV and RWA legal wrappers, TGE and listing prep - are my Token Launch & RWA service. This one writes the code; those two make it investable and compliant.
What's included
- Solidity contracts - ERC-20, ERC-721, ERC-1155, staking, vesting, escrow and DAO governance built on OpenZeppelin
- Test suite + Slither - Hardhat or Foundry coverage plus Slither static analysis on every build
- Gas optimised - Storage packing and call patterns tuned so per-transaction fees stay low on Base, Polygon and Arbitrum
- Verified deployment - Deployed and source-verified on Etherscan, Basescan or Polygonscan with deployment scripts handed over
- Audit coordination - Third-party audit arranged and findings triaged for high-value contracts
- Multi-chain - Chain recommended on fees, users and ecosystem - Ethereum, Polygon, Base, Arbitrum or BNB
How it works
- 1Spec the contract
Define token, NFT or protocol logic, target chain, economics and the trust assumptions before any code is written
- 2Build + test
Develop on OpenZeppelin with a Hardhat or Foundry test suite, Slither static analysis and gas tuning
- 3Review + audit
Internal security review against reentrancy, overflow and access-control issues, then coordinate a third-party audit for high-value contracts
- 4Deploy + verify
Deploy with scripts, verify source on the explorer and hand over documentation
Why work with me
| With me | Typical agency | |
|---|---|---|
| Test coverage + Slither | Standard on every build | Hope it works |
| Gas optimisation | Storage and calls tuned | Ignored |
| Audit coordinated | Arranged and triaged | Out of scope |
| Verified on explorer | Always, with scripts | Sometimes |
