🐸zkPepe Bridge

For blockchains to join a network of other blockchains, they must have interoperability, which is the capacity to share information with other blockchains. There have been several interoperability solutions developed, each with its benefits and drawbacks. ​

The zkPepe Bridge, a component that enables asset transfer and communication between the zkPepe network and other networks, such as the BNB Chain Mainnet (L1) or any L2 constructed on top of the BNB Chain, is one of these solutions. ​

​From the user's point of view, an asset must be able to be moved between networks without losing any of its original value or usefulness. Additionally, cross-chain messaging is supported, allowing the transfer of payloads between networks. ​

Features

A crucial component of the zkPepe Bridge smart contract depends on exit trees and the global exit tree. The network's main source of truth for the state is the Global Exit Tree Root. With independent logic, the Bridge SC and the two different Global Exit Root administrators for L1 and L2 provide significant network compatibility. ​

​Exit trees and global exit trees are utilized because they allow any L1 and L2 node to validate asset transfers owing to data availability. Because all necessary information is readily available, any node can verify the legitimacy of an asset transfer. Overall, these capabilities enable easy asset movement between various networks while upholding the safety and reliability of the network. ​

​Smart Contract

The Bridge (or deposit) and Claim (or withdrawal) functions are carried out via the zkPepe Bridge Smart Contract (zkPepeBridge.sol). It makes it possible to claim assets that are received in the destination network as well as bridge assets from one network to another. ​
