# Using Remix IDE

## Deploying a Smart Contract on Bitcichain with Remix and MetaMask

### Introduction

This guide will walk you through the process of connecting to Bitcichain, deploying a smart contract using Remix, and interacting with MetaMask for transaction signing.

#### Prerequisites

* [ ] Installed [MetaMask](https://metamask.io/download/) extension in your browser.
* [ ] MetaMask wallet funded with BITCI tokens.

{% hint style="info" %}
**For mainnet**: If you do not have BITCI tokens in your wallet, you can withdraw BITCI to your Metamask wallet using a CEX such as [bitci.com](https://bitci.com/).
{% endhint %}

### Step 1: Connect to Bitcichain

1. Open [Remix](https://remix.ethereum.org/): Visit Remix in your browser.
2. Connect to Bitcichain: In the Remix interface, select "Solidity" on the left sidebar. Click on the "Deploy & Run Transactions" tab, and choose "Injected Web3" as the environment. This connects Remix to your MetaMask wallet.

### Step 2: Write or Import Smart Contract Code

1. Write or Import: Write your smart contract code in the Remix editor or import an existing one.
2. Compile: Click on the "Solidity Compiler" tab, and compile your smart contract code.

### Step 3: Deploy Smart Contract

1. Deploy: Go back to the "Deploy & Run Transactions" tab.
2. Select Contract: Choose the smart contract you want to deploy from the dropdown.
3. Deploy: Click on the "Deploy" button. MetaMask will prompt you to confirm the transaction.

### Step 4: Confirm Transaction in MetaMask

1. MetaMask Prompt: MetaMask will open, showing details of the transaction. Confirm the gas fees and click "Confirm."
2. Wait for Confirmation: Wait for the transaction to be confirmed on Bitcichain.

### Step 5: Interact with Deployed Smart Contract

1. Contract Interaction: Once the contract is deployed, you can interact with it using Remix or other tools.
2. MetaMask Interaction: Use MetaMask for any subsequent transactions related to the smart contract.

Congratulations! You have successfully deployed a smart contract on Bitcichain using Remix and MetaMask. Feel free to explore additional features, and refer to Bitcichain documentation for advanced functionalities.
