I develop ERC-20 token and ERC-721 NFT contracts with defined rules for supply, minting, transfers, and administrative access. You can hire me to turn your token or collection requirements into contract code, automated tests, and deployment documentation.

We’ll define what holders and administrators can do, which rules are fixed, and which settings authorized users can change. The scope can include supply limits, minting permissions, burning, and transfer restrictions according to your requirements.

What’s included:

Agreed contract specification and permission model

ERC-20 or ERC-721 implementation

Supply, minting, burning, and transfer rules where agreed

Automated tests for expected behavior, permissions, and failure cases

Deployment scripts and testnet deployment

Contract documentation and setup instructions

Source code handover and mainnet deployment assistance where agreed

Before implementation, we’ll review privileged actions and define who controls them after deployment. Development testing and code review are part of the agreed scope; an independent security audit is a separate engagement.

Send me your target network, token or NFT requirements, supply rules, and the actions holders and administrators should be able to perform. If you’re still defining the behavior, describe the intended use so we can identify the decisions needed before development.
