About this Gig
I'm Maham, a Blockchain Developer at OptimusFox. 50+ production builds since December 2021 and 64 Fiverr projects at a 4.9 rating.
WHAT I BUILD
ERC20 and BEP20 tokens with tax, burn, reflection or vesting
ICO, presale, launchpad and airdrop contracts
NFT collections with whitelist and reveal, ERC721 and ERC1155
Staking, farming and vault contracts
Complete dApps, contracts plus a React frontend with wallet connect
Audits of contracts you already have, with a written report
TRACK RECORD
15+ Solidity contracts shipped, including upgradeable proxies and DAO governance. I have built a full Uniswap v3 clone, cross-chain bridges between Ethereum and Fantom, and Hyperledger Fabric networks for clients who cannot use a public chain.
WHAT YOU GET
Full source code, Hardhat or Foundry tests, commented code and a deployment guide you can follow. Ethereum, BNB Chain, Polygon, Base and Arbitrum.
Smart contracts hold real money, so I flag risks before you deploy, not after. Message me about what you are building. Custom offers welcome.
Keep your assets and information safe
Cryptocurrency services focus solely on developing and programming. Never share sensitive information or private keys with others.
FAQ
Will you deploy the contract to mainnet for me?
Yes. Mainnet deployment and source code verification is available as an extra, and it is included in the Token Launch and Full dApp packages. You cover the gas fees and I will estimate those for you before we start.
Do I own the code?
Completely. You receive the full source code, the deployment scripts and the test suite. I keep no rights and no backdoor, and ownership of the deployed contract is transferred to your wallet.
Can you audit a contract someone else wrote?
Yes. Send me the source or the verified contract address. You get a written report covering security findings by severity, gas inefficiencies and recommended fixes. I can implement the fixes as a separate order.
What if I need something not listed here?
Message me. Most of my work is custom. Describe what you need and I will send a custom offer with a fixed scope and price. If I am not the right person for the job I will tell you that instead.
