Tutorial - Deploy Smart Contracts using the Ultra Smart Contract VS Code Extension

Once you have an abi and wasm file for your contract, you are ready for deployment.

Goal

The goal of this tutorial is to guide you through deploying a smart contract using the Ultra Smart Contract VS Code Extension.

Prerequisites

• A compiled smart contract (.wasm and .abi files). Refer to the Tutorial - Compile Smart Contracts using the Ultra Smart Contract VS Code Extension for more information.
• A public-private key pair for your developer Testnet account. If you haven't generated a key pair yet, refer to Tutorial - Generate a key and create a developer Testnet account
• Your account must have sufficient UOS tokens for transactions and fees. Refer to Tutorial - Using the Faucet and Buying RAM on Ultra Testnet for more information.

INFO

The tutorial is up-to-date with version 1.4.2 of the VS Code extension

Add Developer Testnet Account

Before you can deploy a smart contract, you will need to add your developer Testnet account to the Ultra Smart Contract VS Code Extension. To do so, follow these steps:

1. Using the Command Palette (F1), type and select Ultra: Wallet - Create.
2. Enter a password for your wallet and re-enter the password to confirm it. Please make a note of this as it will be needed later to unlock the wallet.
3. Enter the private key for your developer Testnet account.
4. You will see a prompt on the bottom right that says Added Public Key.

You have now added your developer testnet account to the Ultra Smart Contract VS Code Extension.

Deploy Contract

1. Using the Command Palette (F1), type and select Ultra: Deploy Contract.

2. Select the contract you want to deploy.

3. Select the Ultra Testnet endpoint.

4. Unlock your wallet by entering your wallet password.

5. Enter the account you want to deploy this contract to. For the sake of this contract, you should deploy to your own developer Testnet account.

6. If successful you will see the smart contract has been deployed in the output window.

Redeploy Smart Contract

After you've made some changes to your contract, you will need to build it again and redeploy.

Redeploying the contract is identical to the first time you've deployed the contract. Just follow the above instructions and use the same account to deploy to.

Troubleshooting Deployment Errors

If you run into any issues during the deployment, refer to Troubleshooting Deployment for more information.
