Blockchain bridge (blockchain switch, blockchain gateway) is a mechanism that facilitates interaction and data transfer between different blockchain networks. It allows for the transfer of assets, information, or the execution of smart contracts between different blockchains that would otherwise be isolated from each other.

Blockchain bridges play an important role in establishing connectivity between different blockchain networks and enable the exchange of data and assets between them. They can be used to implement cross-chain operations, such as cryptocurrency exchange between different blockchains, transfer of assets from one network to another, or the execution of smart contracts using data from multiple blockchains.

Thanks to blockchain bridges, users can benefit from different blockchain networks and utilize their interoperability for various purposes.
