How to Bridge to Unichain

Can I Bridge to Unichain?

Yes, you can bridge assets to Unichain using crypto bridges that support OP Stack rollups. These enable direct transfers of ETH, USDC, and other tokens from Ethereum-compatible networks.

To bridge, connect an Ethereum wallet to a supported bridge, select Unichain as the destination, and confirm the transaction. As part of the Optimism Superchain, Unichain uses shared sequencing and native interoperability for fast, low-cost transfers.

How to Bridge to Unichain

The easiest way to transfer assets to Unichain is through Rhino.fi, a cross-chain bridge supporting Ethereum Layer 2s. With $4 billion+ in volume and 5 million transfers, Rhino.fi enables fast, low-cost swaps of ETH, USDC, and other tokens across 25+ networks.

Steps to Bridge to Unichain:

1. Connect Your Wallet: Go to Rhino.fi and link an Ethereum-compatible wallet such as MetaMask or Rabby.
2. Select Unichain as the Destination: Choose your source network (e.g., Ethereum or Base) and set Unichain as the target. Pick the token you want to transfer.
3. Enter Amount & Approve: Input the amount, approve the transaction in your wallet, and confirm.
4. Finalize the Transfer: Your assets will arrive on Unichain in seconds, ready to use across its DeFi ecosystem.

Unichain Bridging Fees

Bridging to Unichain via Rhino.fi incurs a 0.19% transaction fee, plus gas fees that vary by source network:

• Ethereum Mainnet: Typically $5–$10, depending on congestion.
• Layer 2 Networks (e.g. Base): Usually under $1, benefiting from L2 cost efficiency.
• Other Layer 1 Networks: Generally less than $1, but fees fluctuate with demand.

Bridging from a Layer 2 network is the most cost-effective option, minimizing gas and transaction costs.

Best Alternative Unichain Bridges

In addition to Rhino.fi, several other bridges support asset tranrs to Unichain:

• Superbridge: Designed for Optimism’s Superchain, enabling direct transfers between all Superchain Layer 2s, including Unichain.
• Across Protocol: Specializes in L2-to-L2 transfers, allowing capital-efficient movement of assets between Unichain, Optimism, Arbitrum and 20 other networks.
• Brid.gg: Another purpose-built bridge for Optimism Superchain layer 2’s that supports Unichain bridges with zero fees (but higher slippage on large orders).

Each option provides low-cost, efficient bridging based on your source network and transfer needs.
