# Web Interface

Deploy SRC20 tokens from a browser using the SRC20 Factory web interface

The SRC20 Factory ships a React web GUI (`packages/web`) for deploying tokens directly from a browser wallet, no CLI or code required.

## Running the web app

Clone the repo and start the dev server:

```bash
bun install
bun run dev:web
```

## Deploying a token

1. Open the web app and connect MetaMask
2. Switch to the Seismic testnet (chain ID 5124)
3. Fill in the token name, symbol, and initial supply
4. Click **Deploy** and confirm the transaction in your wallet
5. The deployed token address and transaction hash appear on success

{% hint style="info" %}
Supply is entered in whole tokens. Entering `1000000` mints `1,000,000 × 10¹⁸` base units.
{% endhint %}

## Wagmi configuration

The web app connects MetaMask to Seismic testnet via wagmi:

```typescript
import { createConfig, http } from "wagmi";
import { injected } from "wagmi/connectors";
import { seismicTestnet } from "seismic-viem";

export const wagmiConfig = createConfig({
  chains: [seismicTestnet],
  connectors: [injected({ target: "metaMask" })],
  transports: {
    [seismicTestnet.id]: http(),
  },
});
```

Other wallet connectors (WalletConnect, Coinbase, etc.) are not configured by default but can be added following the [wallet guides](/clients/typescript/react/wallet-guides.md).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.seismic.systems/getting-started/src20-factory/web.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
