Hop is a scalable, rollup-to–rollup general token bridge. It allows users to send tokens quickly from one rollup to another without waiting for the networks challenge period. It works by involving marketmakers (known as Bonder), who pay a small fee to facilitate liquidity at the destination chain. Bonder extends this credit in the form of hTokens, which can then be swapped for their native counterpart in an AMM. Although it is difficult to quantify security, the Hop core team has been working diligently on the protocol for more than a year before it was released to the public. The Hop core team has extensive knowledge in smart contract development. They were smart contract auditors for many years before building Hop.
