How to Bridge to Unichain

To bridge assets to Unichain’s Sepolia testnet, you’ll need to use a cross-chain platform like Superbridge and transfer testnet ETH. As of now, Unichain only supports the testnet bridging, with the mainnet launch pending. Once assets are bridged, you can test transactions and deploy smart contracts on Unichain’s OP Stack-based Layer 2.

Here’s how to bridge to Unichain:

1. Connect Wallet: Go to Superbridge and link your MetaMask or any EVM-compatible wallet.
2. Select Asset: Choose testnet ETH for the transfer.
3. Enter Amount: Specify the amount to bridge and click ‘Bridge.’ Start with a small test amount.
4. Finalize Transfer: Confirm the transaction in your wallet and complete the bridge.

What are the Fees?

When bridging to Unichain's Sepolia testnet from Ethereum Sepolia, you'll need testnet ETH to cover gas fees. These fees are minimal and required to process transactions. 

Testnet ETH can be obtained from Unichain faucets for free, ensuring you have enough to complete the transfer.

Alternative Unichain Bridges 

The only other officially recommended bridge for Unichain, aside from Superbridge, is Brid.gg. It supports ETH transfers to Unichain from Ethereum Sepolia, OP Sepolia, Base Sepolia, and Lisk Sepolia. 

Brid.gg is recommended by the Unichain team as a reliable option for developers and users needing to bridge testnet ETH across these networks.
