+title: RLC Bridge
+description:
+  Bridge RLC tokens between networks to interact with the iExec protocol.
+  Transfer RLC to Bellecour (xRLC) and Arbitrum networks using dedicated bridges
+---
+
+# 🌉 RLC Bridge
+
+**RLC** (RLC Token) is the essential cryptocurrency for interacting with the iExec protocol. Whether you are executing tasks, accessing protected data, or participating in the iExec decentralized confidential computing network, you will need RLC tokens on the appropriate network.
+
+This guide helps you bridge RLC tokens to **Bellecour** (becoming xRLC) and **Arbitrum** networks using dedicated bridge solutions.
+
+## 🎯 Why Bridge RLC?
+
+RLC tokens are required for various iExec protocol interactions:
+
+- **Task Execution**: Pay for confidential computing tasks
+- **Data Access**: Purchase access to protected datasets
+- **Protocol Participation**: Stake tokens for workerpool operations
+- **Application Usage**: Pay for iApp executions
+- **Data Protection**: Cover costs for data encryption and storage
+
+### Network-Specific Requirements
+
+- **Bellecour Network**: Uses **xRLC** (bridged RLC) for gasless transactions
+- **Arbitrum Network**: Uses **RLC** for mainnet operations with lower gas fees
+
+## 🗂️ Available Bridges
+
+iExec provides dedicated bridge solutions for seamless token transfers across networks:

+## 🔄 Bellecour Bridge (RLC → xRLC)
+
+The **Bellecour Bridge** enables seamless transfer of RLC tokens from Ethereum mainnet to the Bellecour sidechain, where they become **xRLC** tokens.
+
+### Key Features
+
+- **Gasless Transactions**: Bellecour is a gasless blockchain
+- **Instant Transfers**: Quick bridge operations with minimal waiting time
+- **Native Integration**: Fully integrated with iExec protocol
+- **User-Friendly Interface**: Simple and intuitive bridge interface
+
+### How to Bridge to Bellecour
+
+1. **Connect Wallet**: Visit [Bellecour Bridge](https://bridge-bellecour.iex.ec/) and connect your wallet
+2. **Select Amount**: Choose the amount of RLC you want to bridge
+3. **Confirm Transaction**: Approve the bridge transaction on Ethereum mainnet
+4. **Receive xRLC**: Your xRLC tokens will be available on Bellecour network

+  image-alt="Bellecour Bridge Process"
+  link-url="https://bridge-bellecour.iex.ec/"
+  caption="🔗 Start Bridging to Bellecour"
+/>
+
+### Bridge Process Details
+
+The Bellecour bridge operates on a **lock & mint / burn & unlock** principle:
+
+- **Ethereum → Bellecour**: RLC tokens are locked on Ethereum mainnet, and equivalent xRLC tokens are minted on Bellecour
+- **Bellecour → Ethereum**: xRLC tokens are burned on Bellecour, and equivalent RLC tokens are unlocked on Ethereum mainnet
+
+### Using xRLC on Bellecour
+
+Once you have xRLC on Bellecour, you can:
+
+```javascript
+// Deposit xRLC into your iExec account
+iexec.account.deposit(xRLC_amount);
+
+// Check your sRLC balance
+iexec.account.show();
+
+// Use sRLC for task execution
+// Your tasks will automatically use sRLC for payments
+```
+
+## 🌉 Stargate Bridge (RLC → Arbitrum)
+
+The **Stargate Bridge** powered by LayerZero enables cross-chain transfers of RLC tokens to Arbitrum mainnet.
+
+### Key Features
+
+- **Cross-Chain Protocol**: Powered by LayerZero's Stargate protocol
+- **Arbitrum Integration**: Native support for Arbitrum mainnet
+- **Fast Transfers**: Optimized for cross-chain efficiency
+- **Security**: Audited and secure bridge infrastructure
+
+### How to Bridge to Arbitrum
+
+1. **Visit Stargate**: Go to [Stargate Protocol](https://stargateprotocol.com/)
+2. **Connect Wallet**: Connect your wallet to the Stargate interface
+3. **Select Networks**: Choose Ethereum as source and Arbitrum as destination
+4. **Select Token**: Choose RLC as the token to bridge
+5. **Enter Amount**: Specify the amount of RLC to transfer
+6. **Confirm Transaction**: Approve the bridge transaction

+  caption="🔗 Access Stargate Bridge"
+/>
+
+### Bridge Process Details
+
+Stargate uses LayerZero's cross-chain messaging protocol:
+
+- **Source Chain**: RLC tokens are locked/burned on the source chain
+- **Cross-Chain Message**: LayerZero relays the transfer message
+- **Destination Chain**: Equivalent RLC tokens are minted/unlocked on Arbitrum
