# ÆRC Bridge

The æternity Bridge enables seamless asset transfer between æternity and EVM-compatible blockchains through contracts provided by Acurast. This documentation covers the setup, deployment, and usage of the Bridge interface.

Installation and Setup

Prerequisites • Node.js • npm • yarn

Local Development Setup

1. Install dependencies:

```bash
yarn
```

2. Start development server:

```bash
yarn start
```

Production Build

1. Build the application:

Self-Hosting Guide

Cloud Deployment You can deploy your own instance of the Bridge interface using various cloud services:

1. Fork the repository from GitHub
2. Create an account on your preferred cloud platform: • Vercel • Netlify • AWS • Others
3. Connect your GitHub account to the cloud platform
4. Create a new application
5. Configure using standard Node.js deployment settings
6. Deploy your instance

### Understanding Bridge Mechanics

#### Token Bridging Process

```mermaid
graph LR
    A[Source Chain] -->|Lock Tokens| B[Bridge Contract]
    B -->|Notify| C[Bridge Service]
    C -->|Release| D[Target Chain]
```

The bridge operates through a lock-and-mint mechanism:

1. Tokens are locked in the source chain's bridge contract
2. Bridge service verifies the lock transaction
3. Equivalent tokens are released on the target chain

#### Native Currency Bridging

When bridging native currencies:

* ETH → æternity: Receives wETH (AEX-9 token)
* AE → Ethereum: Receives wAE (ERC-20 token)

### Security and Verification

The bridge maintains a 1:1 ratio between locked and released assets. You can verify this through:

* Smart contract inspection on both chains
* Public contract addresses
* Real-time bridge statistics
