What Is the Concept of “Bridging” Assets between Layer-1 and Layer-2?

Bridging is the process of moving a token from the main Layer-1 blockchain to a Layer-2 scaling solution. This typically involves locking the asset in a smart contract on Layer-1 and minting an equivalent "wrapped" representation on Layer-2.

This allows the asset to benefit from Layer-2's speed and low cost, while the original asset remains secured on Layer-1.
