RLC Bridge

RLC (RLC Token) powers all iExec protocol interactions. You need RLC tokens whether you're executing tasks, accessing protected data, or participating in the iExec confidential computing network.

This guide helps you bridge RLC tokens to Bellecour (becoming xRLC) and Arbitrum networks using the Bellecour Bridge and Stargate Bridge.

🗂️ Available Bridges

iExec provides officially supported bridges for seamless token transfer across networks:

Bellecour Bridge

Live

Bridge RLC tokens between Ethereum mainnet and Bellecour sidechain

Access Bridge

Stargate Bridge

Live

Bridge RLC tokens between Ethereum and Arbitrum using LayerZero protocol

Access Bridge

⚡ Stargate Bridge

The Stargate Bridge powered by LayerZero enables cross-chain transfers of RLC tokens between Ethereum and Arbitrum mainnet in both directions.

Ethereum <> Arbitrum (RLC <> RLC)

1. Visit Stargate: Go to Stargate UI
2. Connect Wallet: Connect your wallet to the Stargate interface
3. Select Networks: Choose your source network (Ethereum or Arbitrum) and destination network
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 and wait for confirmation

🔄 Bidirectional Bridge

The Stargate bridge interface automatically detects your wallet's network and available RLC tokens. The process is similar in both directions - simply select the appropriate source and destination networks to transfer RLC between Ethereum and Arbitrum seamlessly.

🔄 Bellecour Bridge

The Bellecour Bridge enables seamless transfer of RLC tokens between Ethereum mainnet and the Bellecour sidechain in both directions. When bridged to Bellecour, RLC becomes xRLC, the native asset of the Bellecour network.

Ethereum <> Bellecour (RLC <> xRLC)

1. Connect Wallet: Visit Bellecour Bridge UI and connect your wallet
2. Select Source Network: The bridge automatically detects your current network and available tokens (RLC on Ethereum or xRLC on Bellecour)
3. Choose Destination: The bridge will show the opposite network as destination automatically
4. Select Amount: Choose the amount of tokens you want to bridge
5. Confirm Transaction: Approve the bridge transaction and wait for confirmation
6. Receive Tokens: Your tokens will be available on the destination network

🔄 Bidirectional Bridge

The bridge interface automatically detects your wallet's network and available tokens. The process is similar in both directions - simply switch to the appropriate network (source chain) in your wallet and refresh the page to update the bridge direction, then the bridge will handle the conversion between RLC and xRLC seamlessly.

🔒 Security & Audits

The Stargate Bridge uses the LayerZero protocol under the hood, which provides secure cross-chain communication infrastructure. LayerZero is a decentralized protocol that enables trustless cross-chain messaging without requiring intermediate chains or wrapped tokens.

The RLC multichain bridge implementation has been thoroughly audited by Halborn, a leading blockchain security firm. The audit report is accessible at halborn.com/audits.
