 After encoding the data, it's necessary to format it as a `Uint8Array` array for smart contract interactions and blockchain transactions. In Solidity, the data type for byte arrays data is `bytes`. However, when working in a JavaScript environment, such as when using the `ethers.js` library, the equivalent data structure is a `Uint8Array`.
