Solidity is a high-level programming language primarily used for writing smart contracts on blockchain platforms, notably Ethereum. Smart contracts are self-executing contracts with the terms of the agreement directly written into code. Solidity allows developers to create these smart contracts, defining rules and functionalities for decentralized applications (dApps) on the Ethereum network.

Note: Please note that the course comes with online e-learning (videos) only. No hard copy will be provided.

Why should one take Solidity Certification?

Solidity’s importance and relevance stem from its role in facilitating the creation of decentralized applications and enabling the execution of secure and transparent transactions without intermediaries. Solidity helps developers implement business logic, encode contractual agreements, and automate various processes within blockchain networks.
