Vertex Edge - The Concept

Edge functions like a virtual market maker between exchange venues on different chains. The state of the sequencer is split (e.g., sharded) between supported chains concurrently, intaking and cloning inbound orders from each chain. Independent orders from one chain are then matched against liquidity from multiple chains. Both sides of the trade are filled out, and the sequencer (Edge) takes the opposite side of the inbound trades — automatically hedging and rebalancing liquidity on the back-end between chains. Notably, the sequencer only mirrors resting liquidity (e.g., maker orders) across the sharded states of the Vertex instances on different base layers. Taker orders remain unchanged, and are submitted directly from an independent Vertex instance, such as the DEX Blitz, to the sequencer’s unified liquidity layer — Edge. Order matching between chains occurs concurrently, with the state of the sequencer’s consolidated liquidity profile across all of the supported base layers sharded and propagated to each Vertex instance. As a result, Edge is capable of matching inbound orders from one chain with the combined orderbook liquidity of all of the base layers plugged into the Vertex sequencer.
