About the test

This assessment focuses on evaluating candidates' proficiency in designing, developing, and deploying Smart Contracts, which are self-executing contracts with the terms of the agreement directly written into lines of code. The test comprises advanced-level questions that cover a wide range of topics including Solidity programming, Ethereum blockchain fundamentals, smart contract security measures, gas optimization techniques, and interfacing with external sources such as oracles. It aims to identify candidates who are not only technically skilled in smart contract development but also possess a deep understanding of blockchain technology, its architectural design, and its implications on decentralization and transaction execution. By meticulously assessing candidates on these competencies, this test ensures that the candidates are well-versed in crafting robust, efficient, and secure smart contracts that are vital for the execution of decentralized applications.
