Smart Contract code: I will create and deploy smart contracts that meet the client's specifications. This includes developing the code, testing it thoroughly, and deploying it on the appropriate blockchain network.

DApp (Decentralized Application) development: I will develop decentralized applications that are user-friendly and intuitive. This includes front-end development, back-end development, and integration with the appropriate blockchain network.

API development: I will create API endpoints that enable interaction between the client's application and the blockchain network. This includes designing the API, developing the endpoints, and testing them thoroughly.

Documentation: I will provide detailed documentation for all code developed, including smart contracts, DApps, and APIs. This documentation will enable the client to maintain and update the code in the future.

Support and maintenance: I will provide ongoing support and maintenance for all code developed, ensuring that it continues to function correctly as the blockchain network evolves and changes over time.
