The goal of this tutorial is to compile smart contracts using the Ultra Smart Contract VS Code Extension.

How to Compile ​

There are two ways to compile your smart contract.

First way is to compile using the VS Code Status Bar. Make sure you have the .cpp file open and selected and click Compile at the bottom of VS Code.

Second way to compile is to use the Command Palette (F1) and search for Ultra: Build Contract.

Once the files are compiled you should see an abi and a wasm file next to your compiled smart contract.

For more information about .abi and .wasm files see the official EOS Network Foundation page
