Deploy Your First Contract

This guide will walk you through deploying and interacting with contracts in REMIX.

  1. Load and Compile a Contract.

    Open the REMIX IDE. By default, REMIX provides a sample workspace. Choose a Solidity contract to compile and click the ▶️ button. Alternatively, use the Solidity Compiler tab to compile the selected contract.

Interact with Your Deployed Contract​

  1. Interact with Deployed Contracts.

    Once deployed, your contract will appear in the Deployed/Unpinned Contracts section of the Deploy & Run tab. To keep your contract visible after reloading Remix, pin it to the workspace. Pinning a contract moves it to the Pinned Contracts section, ensuring it won't disappear upon reload. When pinned, Remix will save both the contract’s address and its ABI for easy access.

    You can interact with your contract by calling its methods from this section, with all transactions routed through MetaMask.

  2. Run Tests.

    Currently, REMIX supports JavaScript tests only. To run tests, navigate to the File Explorer and select any JavaScript test file in the tests directory.

    Run it by clicking the ▶️ button.

How to Interact with Already Deployed Contracts​

If you need to interact with already deployed contracts, make sure to note down their addresses beforehand so you can load them later using the At Address button.
