Blockchain technology has grown enormously in diverse, intelligent applications with high security, transparency, and trust, but performance analysis is still a concern. Various debugging and analysis tools exist that can be used to eliminate bugs and vulnerabilities in smart contracts. However, these tools are only a little capable of making the solution attack-resistant. This research improves the performance analysis smart contract in the Remix IDE platform. The analysis detects and debugs security and vulnerability issues and minimizes the gas and economy from various smart contract fragments, especially in the Solidity language. This research reduced the number of vulnerabilities to 82 compared to 641 in previous work. The gas fee consumption and code size were also considerably reduced by tens of thousands of Wei, thus improving the performance. The gas fee is reduced by removing unnecessary events, using bytes instead of a string, using the required function, packing the structure tightly, activating the optimizer, using short circuit rules, and using an external function. Also, the code size is reduced using inheritance, modifiers, and removing extra comments. To use inheritance and virtual concepts, the work is deployed on the latest compiler version, i.e., 0.8.17+ commit. The solidity static analysis helped remove vulnerabilities such as similar variable names, use of constructor(), etc. The paper presents a novel approach for researchers to write efficient smart contracts and make an optimized system. The developed system was finally tested on the Goerli test network of Ethereum using Remix IDE, and the results proved the efficiency of the smart contract.
