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 Arbitrum using the Stargate Bridge.

🧪 Testing on Arbitrum Sepolia

For development and testing purposes, you can get free RLC tokens on Arbitrum Sepolia testnet using the iExec RLC Faucet. This allows you to test your iApps, pay for workerpool executions, and access protected datasets without spending real tokens.

Available Bridges

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

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

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.
