What Is Hop Exchange(HOP)?
Hop Exchange is a multichain bridge connecting Ethereum with Layer-2 networks. Using Hop, users can send tokens almost instantly across networks instead of having to wait multiple days. There are two core pieces to the Hop protocol architecture that make this possible. A cross-network Hop bridge token that can be quickly and economically moved between L2’s or claimed on layer-1 for its underlying asset. Automated Market Makers to swap between each Hop bridge token and its corresponding Canonical Token on each rollup in order to dynamically price liquidity and incentivize the rebalancing of liquidity across the network.

Prior Work
Bridging assets across blockchain networks is not a new problem. Solutions used to bridge various layer-1 networks and variants thereof may be useful for bridging rollups as well.
Proof of Authority Bridges
Proof of Authority (PoA) bridges rely on a set of authorities to attest that a token has been locked up in its native environment and then mint a representation of that token in the destination environment. This method is efficient but introduces a new trust assumption: the authorities will remain honest. A dishonest majority of the authorities can steal the locked funds and flood the destination environment with tokens that are no longer collateralized.
Hop Protocol
The Hop protocol provides a scalable rollup-to-rollup General Token Bridge using a two-pronged approach:
- Create a cross-network bridge token that can be quickly and economically moved from rollup to rollup or claimed on layer-1 for its underlying asset.
- Use Automated Market Makers to swap between each bridge token and its corresponding Canonical Tokens on each rollup in order to dynamically price liquidity and incentivize the rebalancing of liquidity across the
network. - The combined approach allows users to quickly and restlessly swap between layer-2 Canonical Tokens using the specialized bridge token as an intermediary asset.
Hop Bridge Tokens
Hop Bridge Tokens (e.g., ”Hop ETH”, ”Hop DAI” with symbols ”hETH”, ”hDAI” respectively) are specialized layer-2 tokens that can be transferred rollup-to-rollup in batches and act as intermediary assets in the Hop protocol. Each Hop Bridge Token represents a deposit in the layer-1 Hop Bridge contract. For example, if 4 ETH are deposited into the layer-1 Hop Bridge contract, 4 Hop ETH can be minted from a layer-2 Hop Bridge contract.
Hop Bridge token can be redeemed for its underlying asset on layer-1, which burns the Hop Bridge Token being redeemed on layer-2. When a Hop Bridge Token is transferred from rollup to rollup, it is burned on the origin rollup and minted on the destination rollup. As explained below, these immediate transfers are accomplished by allowing a ”Bonder” to front liquidity on the destination in exchange for a small fee. The Bonder’s liquidity is returned.
Automated Market Makers
Each Hop Bridge Token represents a layer-1 token and can be quickly and economically moved from rollup to rollup. Under normal network conditions, each Hop Bridge Token is worth exactly 1 of its L1 counterpart because it can be redeemed on layer-1 at any time. However, third parties on each rollup are not likely to adopt Hop Bridge Tokens directly. It is more likely that the Canonical Tokens they adopt are produced by the rollup’s Native Token Bridge or an Application-Specific Token Bridge as previously discussed. To complete the bridge between the layer-1 token and its Canonical layer-2 counterpart, an Automated Market Maker (AMM) can be deployed to enable swaps between each Hop Bridge Token and its corresponding Canonical Token (e.g., Hop ETH – Canonical L2 ETH).
