**Smart Contract Writing Practice**
Today I recorded a practical experience of smart contract writing. From preliminary design, coding implementation to test deployment, I encountered many problems in each link. Through gradual investigation and optimization, I finally realized a safe and efficient contract. Attached are the screenshots of the contract code and test report, and explain in detail how to use Solidity to write and deploy smart contracts. I hope to provide practical experience sharing for blockchain developers.
