I will develop secure custom solidity smart contracts
About this Gig
I develop custom Solidity smart contracts for Ethereum and EVM-compatible networks, including Base, Polygon, and Robinhood Chain.
I built the smart contract architecture behind a production NFT marketplace and drop launchpad.
My experience includes:
ERC-721, ERC-721A, and ERC-1155
ERC-2981 royalties
Factory, clone, and proxy patterns
Marketplace listings and bids
Payments and access control
Automated contract testing
Check my work here: https://github.com/ChainAI-Networks-GmbH/aitonft-contracts
You receive:
Clean, documented Solidity source code
Tests covering expected behavior and relevant edge cases
Security-focused implementation using established patterns
Deployment scripts and documentation based on your package
Clear communication about risks and technical decisions
I do not deliver copy-paste contracts. Development testing does not replace an independent security audit.
Complex marketplaces, DeFi systems, upgradeable architectures, and frontend integrations require a custom offer.
Please contact me before ordering to confirm the scope and network.
I never request private keys. Network gas fees are not included.
Token standard:
ERC-721

FAQ
Which blockchain networks do you support?
I develop Solidity contracts for Ethereum and EVM-compatible networks, including Base, Polygon, Robinhood Chain, Arbitrum, Optimism, and BNB Chain. Please contact me to confirm your preferred network.
Which types of smart contracts can you develop?
I develop ERC-721, ERC-721A, ERC-1155, royalty, access-control, payment, factory, proxy, marketplace, listing, and bidding contracts. Complex systems require a custom offer.
Does your service include a security audit?
No. I follow security-focused development practices and provide automated tests, but this is not an independent security audit or certification. High-value contracts should be reviewed by an independent auditor before mainnet deployment.
Do you need my wallet private key?
No. Never share your private key or seed phrase. Deployment is completed through your wallet or with guided support. I will never ask for secret wallet credentials.
Are deployment and gas fees included?
Deployment is included only in packages or extras that explicitly state it. Blockchain gas fees are paid separately by the client through their own wallet.
