I will develop and test solidity smart contracts for your web3 dapp
Meta Ads Specialist and Web3 Developer
I'm Rayyan, a Digital Marketer and Developer helping businesses grow online and build reliable tech. I cover two sides of digital growth: high-converting ad campaigns and Solidity smart contracts for ...
About this Gig
I write, test, and deploy Solidity smart contracts for Web3 projects from a single custom contract to a multi-contract system with a working frontend and database integration.
What I offer:
- Custom Solidity smart contracts (ERC20 tokens or custom logic)
- Full unit testing for contract functions and edge cases
- Public testnet deployment
- Multi-contract systems (access control, staking-style logic, etc.)
- Frontend and database integration for full dApp packages
I'm a Computer Science student actively building in Web3 currently developing a blockchain-based supply chain traceability system as my final year project. I write clean, tested code and stay hands-on through every step of debugging and delivery.
Note: Testnet deployment is included in every package. Mainnet deployment involves real gas fees and stays the client's responsibility.
Message me before ordering so I can confirm scope and recommend the right package for your project.

FAQ
Q: What do you need from me to get started?
A: A short description of what your contract should do (token, custom logic, etc.), which network/testnet you'd like it on, and any specific features you need. If you're not sure, message me and I'll help you scope it out.
Q: Do you deploy to mainnet?
A: Every package includes testnet deployment. Mainnet deployment can be discussed separately, but gas fees and deployment responsibility stay with you as the project owner, since that involves real funds.
Q: Will I get the full source code?
A: Yes — every package includes full, commented source code that's yours to keep and use however you need.
Q: Do you test the contracts before delivery?
A: Yes, every contract goes through a unit test suite covering core functions and edge cases before delivery, so you're not getting untested code.
Q: Do you offer support after delivery?
A: Yes, minor fixes and questions related to the delivered work are covered for a short period after delivery.
Q: Can you help with token presales, launchpads, or DeFi platforms?
A: That's not currently my focus — I specialize in smart contract correctness, testing, and clean dApp architecture rather than tokenomics or sale mechanics. Happy to discuss if your project has a different angle on this.
