## Remix Contract Verification Plugin

Remix IDE offers an automated contract verification solution through its Contract Verification plugin, which integrates with both Sourcify and Etherscan verification services.

### Setup and Configuration

1. **Activate the Plugin**: In Remix IDE, navigate to the Plugin Manager and activate the **Contract Verification** plugin.

2. **Configure Network Settings**:

- Search for and select **Sei** as your blockchain
- Choose your deployment environment:
- **Testnet** (1328) for development
- **Mainnet** (1329) for production

3. **Enable Verification Services**: Activate both verification methods:

- ✅ **Sourcify**
- ✅ **Etherscan**

4. **Etherscan Configuration**: Configure the following settings:
- **API Key**: Obtain from [seiscan.io](https://seiscan.io)
- **URL**: `https://seiscan.io`

### Deploy and Verify

Once configured, deploy your contract through Remix as usual. The Contract Verification plugin will automatically verify your contract upon successful deployment, submitting to both Sourcify and Seiscan simultaneously.

Verification status will be displayed in the plugin interface, and your verified contract will be publicly viewable on Seiscan explorer.

## Verify via 0xngmi Etherscan Verification (third‑party)

You can batch‑verify a contract that is already verified on another chain using the community tool [Etherscan Verification by 0xngmi](https://etherscan-verification.0xngmi.com/). This copies the verified source from a “source chain” and submits it to [Seiscan](https://seiscan.io), as long as the bytecode and compiler settings match.
