Q: How does AmaraLink work?

A: Two contracts of one asset are deployed respectively on two target chains A and B. After depositing the asset into the contract on chain A, the contract on chain A confirms and locks the asset. Receiving the news, the contract on chain B maps the corresponding asset which is also valuable and recognized by chain B. Therefore, it's not a real asset transfer but a mapping on another chain. This is how AmaraLink works.
