Uniswap, one of the most popular decentralized exchanges (DEX) built on the Ethereum (ETH) network, launched today, October 23, 2024, a permissionless bridge that allows users to make cross-chain transactions directly from its interface and wallet.
This multi-chain bridge is available in beta versionas does Uniswap’s recently created network, Unichain. This chain was launched in testnet format and the main network will be open “soon” according to its roadmap.
The new feature of this DEX is initially enabled for nine networks: EthereumBase, Arbitrum, Polygon, OP Mainnet, Zora, Blast, World Chain and ZKsync.
Furthermore, in the advertisement They explained that only the native tokens of these networks (such as Ethereum’s ether or Arbitrum’s ARB) and stablecoins will be compatible with the connection of this multi-chain bridge.
Thus, the integration of this bridge means that users can interact with different networks, move assets, carry out exchanges and add liquidity to the pools. without leaving the interface of Uniswap.
This functionality would facilitate interoperability between different chains. For example, a user could exchange Ethereum tokens for another token from one of the eight networks that include this permissionless bridge, all directly from Uniswap. This saves time and reduces technical friction.
To use this function, users must, after choosing the asset they wish to link between these networks and then enter the new section of the DEX “swap across networks”.
Uniswap users can now swap tokens between 9 chains without leaving this app. Fountain: Uniswap.
On the other hand, if you wanted to use this bridge on Uniswap To make a transfer of 1 ether from the Ethereum Sepolia (Ethereum test network) to Base Sepolia, no commission fees would be applied to the service.
However, you would have to pay a gas commission cost. In this case it would be 0.0002472 ETH, which at the time of writing this is equivalent to 0.62 dollars. These fees are used to pay validators for their computational effort. Additionally, it would take 3 minutes for the transfer to complete.
Uniswap users can nowThe Uniswap feature of the new multi-chain bridge is in its beta version. Fountain: Superbridge.
To build this solution, from the DEX they point out that the Across protocol is a multi-chain bridging solution that enables “fast and secure” cross-chain transactions.
One of the biggest concerns with multi-chain bridges is security when transferring assets.
In this sense, according to their documentsAcross uses a security mechanism based on a modular architecture divided into three layers: “Intents” layer, the relay layer and the settlement layer.
This modular system segment responsibilities security in the three separate layers, which would help reduce the risk of failures or vulnerabilities, and allows for more efficient and scalable management of the protocol.
These layers fulfill specific functions that together form a complete system of cross-chain interoperability.
This is how the Across three-layer system works
In the Intents Layer, users express their intentions or desires. For example, a user may want to transfer USDC from Ethereum to a second layer (L2) network or perform a token swap on the destination network.
The user deposits the assets on the source network and specifies what they want to happen on the destination network.
On the other hand, the second layer is designed to ensure that the transactions, which have been recorded and sent by the previous layer, are correct and valid.
Here relays (also known as “solvers”) play a key role. They compete to fulfill users’ intentions. These relayers, individuals or entities, must advance their own capital to complete the transactions and in exchange receive rewards in Across’s native token, ACX.
Due to competition between relays, users get their orders fulfilled “quickly and at low cost.”
Ultimately, once the relay has fulfilled the user’s intent, the Settlement Layer ensures that the assets reach their final destination, be it the destination Blockchain or the user’s wallet.
Settlement is carried out using the data verification protocol Optimistic Oracle (OO) of UMA, which would minimize chain actions and reduce costs.
Thus, Uniswap is committed to offering a unified experience, where users do not have to interact directly with multiple bridges or interfaces.
