# Bridges (/docs/unichain/tools/bridges)

Bridge assets from Ethereum and other networks to Unichain mainnet and Sepolia.

## Superbridge
[Superbridge](https://superbridge.app) enables you to bridge ETH and other supported assets from Ethereum (L1) to Unichain (L2).

## Supported networks
* [Unichain Mainnet](https://superbridge.app/unichain)
* [Unichain Sepolia Testnet](https://superbridge.app/unichain-sepolia)

## Across
[Across](https://across.to/) is an interoperability protocol powered by intents, enabling fast, low-cost value transfer with different security tradeoffs compared with traditional bridge designs. It uses an intent-based architecture that decouples user experience from settlement, allowing instant transfers while maintaining security.

## Supported networks
* [Unichain Mainnet](https://app.across.to/)

## Brid.gg
Use [Brid.gg](https://brid.gg) to bring assets from L1 onto Unichain.

## Supported networks
* [Unichain Mainnet](https://brid.gg/unichain)
* [Unichain Sepolia Testnet](https://testnet.brid.gg/unichain-sepolia)

## Allbridge
[Allbridge](https://allbridge.io/) Core enables the transfer of value between blockchains by offering cross-chain swaps of native stablecoins. Being messaging protocol agnostic, Allbridge Core connects a variety of EVM and non-EVM networks.

## Supported networks
* [Unichain Mainnet](https://core.allbridge.io)
* [Unichain Sepolia Testnet](https://core.allbridge.io)

## Synapse
[Synapse Protocol](https://synapseprotocol.com/) allows you to bridge between 8 different EVM and blockchains with zero-slippage and in under 5 seconds.

## Supported networks
* [Unichain Mainnet](https://synapseprotocol.com)
* [Unichain Sepolia Testnet](https://synapseprotocol.com)

## Thirdweb
Use thirdweb to swap and bridge assets from ETH to Unichain!

## Supported networks
* [Unichain Mainnet](https://thirdweb.com/unichain)
* [Unichain Sepolia Testnet](https://thirdweb.com/unichain-sepolia-testnet)

## Relay
[Relay](https://relay.link/bridge/base?fromChainId=130) is a cross-chain payments system that enables fast, affordable bridging and cross-chain execution by connecting users with relayers, financial agents that act on users' behalf across chains for a small fee. It minimizes gas costs and execution latency, making it useful for payments, bridging, NFT minting, and gas abstraction.

## Supported networks
* [Unichain Mainnet](https://relay.link/bridge/base?fromChainId=130)

## Orbiter Finance
[Orbiter Finance](https://www.orbiter.finance) is a decentralized cross-rollup bridge that offers fast, secure, and cost-efficient asset transfers. It supports near-instant bridging between Ethereum and emerging Layer 2 networks. Orbiter enables seamless user experience with minimal fees by optimizing rollup infrastructure.

## Supported networks
* [Unichain Mainnet](https://www.orbiter.finance/bridge/Ethereum/Unichain?token=ETH)
