Transition-metal dichalcogenides (TMDs) host tightly bound electron-hole pairs—excitons—which can be either optically bright or dark based on spin and momentum selection rules. In tungsten-based TMDs, a momentum-forbidden dark exciton is the energy ground state, and therefore, it strongly affects the emission properties.

Solidity Execute is an easy-to-use smart contract interaction tool built to interact with smart contracts on any EVM based network like Ethereum, Polygon. In this section, we will revoke the approval of the ERC20 token from the malicious spender using solidity execute vscode extension. Let's start with compiling a ERC20 contract using Hardhat and get into Solidity Execute environment.
