Cross Bridges

In crypto technology a cross bridge is a combination of smart-contracts across multiple blockchain networks that facilitate interoperability and transactions across different cryptoassets.

Cross bridges are commonly used for money laundering transactions in which multiple cryptoassets are swapped in a method called chain-hopping which is used to obscure the provenance of funds associated with illicit financing.
