Summary: The Sei Network, a new Layer 1 blockchain optimized for DeFi applications, can be accessed via Ethereum, Polygon, Avalanche, BNB Chain, and other Layer 2 networks using the Vortex Protocol bridge. This decentralized exchange (DEX) provides a cross-chain bridge to transfer assets like USDC and ETH onto the protocol. The fees for such transfers depend on the originating network, with costs ranging between $5 to $25.
Can I Bridge to Sei?
Yes, you can bridge to the Sei Network from Ethereum, Polygon, Avalanche, BNB Chain, and other Layer 2 networks using the Vortex Protocol bridge. This platform is a decentralized exchange (DEX) on the Sei Network and offers a cross-chain bridge enabling users to transfer assets such as USDC and ETH to the protocol.
How to Bridge to Sei Network
As outline above, the only method to bridge to Sei Network from Ethereum, Polygon, Avalanche, BNB Chain and other Layer 2 networks is with the Vortex Protocol bridge. This platform is the largest DEX on Sei that also offers a cross-chain bridge that enables users to transfer assets like USDC and ETH onto the protocol.
You can follow this simple guide to get started:
- Visit Vortex Protocol and connect your wallet.
- Select the network you want to bridge from and Sei Network as your destination.
- Select the token you want to transfer and the amount.
- Review and confirm your transaction.

Fees to Bridge to Sei
The fees to bridge to the Sei Network will depend on which network you are transferring assets from. For example, if you are bridging from Ethereum mainnet, fees will likely be between $15 and $25 depending on gas fees at the time. If you are bridging from an alternative layer 1 like BNB or Avalanche, fees will be slightly cheaper and between $5-$10 to move assets in either direction.
What is Sei?
Sei is another new Layer 1 blockchain that leverages the Cosmos SDK to create an environment for app-chains to build highly performant DeFi applications. Their network comes with an in-built order book for DeFi developers to easily build and deploy financial applications like decentralized exchanges, perpetual swap platforms, options protocols and much more.
Final Thoughts
In conclusion, the Vortex Protocol bridge is the only way to transfer assets to the Sei Network from other Layer 1 and Layer 2 networks. The process is straightforward, but fees will depend on the network used to transfer the assets. Sei is a Layer 1 blockchain that offers a high-performance environment for developers to create DeFi applications with an in-built order book.
