MohammedSoliman

Fullstack Web3 Developer

I write Solidity contracts with Foundry, test them hard, and ship React frontends that people can use today on Sepolia. Based in Cairo.

Smart contracts and dApps

Eight builds, all tested with Foundry and deployed to Sepolia. Most have a live frontend you can try with a testnet wallet.

Tokenized Vault

An ERC-4626-style vault. Deposit a token, get non-transferable shares priced by vault balance, and withdraw anytime. Includes a 24-hour faucet cooldown, a live activity feed and a custom wallet modal.

Token Vesting

Grantors lock ERC-20 tokens behind a cliff and 90-day release intervals. Beneficiaries track progress on a dashboard and claim what has vested. Backed by 62 Foundry tests and a written security review.

Dutch Auction

Sellers mint an NFT and list it at a price that falls every second. Buyers settle in one atomic transaction that pays, transfers the NFT and refunds any overpay.

SolidityERC-721IPFS

English Auction

A full NFT auction lifecycle: escrow, strictly rising bids, permissionless settlement and refunds for outbid users. The UI is deliberately monochrome. 49 Foundry tests.

Crowdfund

Backers pledge, withdraw or claim refunds on failed campaigns. Creators launch and claim funds on success. Wrapped in a retro Windows 95 desktop UI.

Escrow

A factory deploys one funded escrow per deal. Funds go to the seller when buyer and seller both approve, and an arbiter settles disputes. 25 Foundry tests.

Soliman Web3 NFT

An owner-minted ERC-721 built on OpenZeppelin, with metadata and images pinned to IPFS. Deployed and verified on Sepolia Etherscan.

ERC-20 Token dApp

A capped, burnable, pausable token with role-based access and gasless EIP-2612 permits. 46 unit and fuzz tests, plus a React dApp to use it.
