The Mantle network is built on top of the Cosmos SDK, which is a foundation for developing blockchain applications. Smart contracts on the Mantle network are often created in the programming language Solidity. A high-level programming language called Solidity was created expressly for creating smart contracts that run on the Ethereum network. It offers features and syntax for creating complicated Decentralized Applications (DApps) with smart contract capability and is commonly utilized by blockchain technology.
