The main concern when using a DEX is the speed. Users that have interacted with a DEX before, will remark the uncomfortable experience of waiting for their trade to confirm on the blockchain or having the trade fail because someone else has traded the order and losing the gas fees.
FINN solves this problem by employing a Hybrid DEX model, where the order book and matching engine is stored on a centralized server while the funds and transactions are recorded on the blockchain. This allows for instant order execution (no need to wait blockchain transaction confirmations) and prevents front-running as all trades are pushed through FIFO (first-in-first-out) orders to the blockchain by the matching engine.
Another advantage to using the hybrid approach is the free order cancellation. On a traditional DEX to cancel an order you would have to send a transaction and pay the gas fee.
The matching engine also tracks the order fills and will not match orders that are already filled and awaiting to be recorded. The user receives instant trade confirmation.
To feel the speed of FiNN Exchange, we encourage you to try out a trade in the DEMO version of the exchange. The DEMO version runs on the Rinkeby Ethereum testnet and performs all the same operations as it would on the mainnet.
