To deploy smart contracts and develop Dapp on Ethereum, you need to learn Solidity - a programing language for Ethreum. In [smart contract development](https://www.gate.io/learn/course/introduction-to-smart-contract-development?ch=roadmap1_course2_20230614&utm_campaign=TR_PmcZ5kQp&utm_content=&utm_medium=CPM&utm_source=CH_79kTf7RP&utm_term= "smart contract development"), you will learn from use cases like simple token contract, voting systems, and how to deploy them on Ethereum using Remix. You will also understand the structure of variables, functions, and modifiers, guided to practice writing your own token contract with Solidity.

In addition to deploying contracts on Ethereum, you also need to know how to call external contracts, connect Metamask wallet ... These also involve recompiling Solidity contract so that it can be used on the web front end.

The final section covers the security risks involved in smart contract development, such as reentrancy attacks, integer overflow, access control, etc. It also provides some development suggestions, such as security audits, using existing patterns, keeping contracts modularized and monitoring abnormal events, to prevent serious errors.
