OpenBook
How has Solana defi responded to the risks that Serum suddenly presented and has there been any traction on Openbook so far? How has liquidity flowed through Solana defi? What programs seemed to be most affected by the replacement of Serum? Does it seem like defi on Solana is becoming more decentralized?
What is Serum?
Serum is a decentralized exchange software built on Solana where cryptocurrencies can be bought and sold by traders.
Solana is a blockchain platform that aims to increase user scalability through faster transaction settlement times. By being deployed on Solana, Serum can fully benefit from the speed and cost effectiveness of transactions settled on its blockchain.
Central to Serum’s design is a decentralized orderbook run by smart contracts that aims to mirror traditional exchanges by matching buyers and sellers. This gives participants flexibility with pricing and order sizes when they submit orders to Serum, giving them full control over their trading.
Serum’s utility token, SRM, enables holders to receive up to a 50 percent discount on their trade fees and stakers to vote and participate in the platform’s governance mechanism.
How Does Serum Work?
Serum’s network and design is meant to facilitate transactions in a way that feels similar to that of traditional exchanges.
By being integrated within the Solana network, Serum benefits from the speed and cost effectiveness of transactions, and allows for them to be settled on its blockchain.
Openbook
One of the aftereffects of the FTX meltdown for Solana was the need to fork (replace) Serum, the OG order book on Solana due to key control risk.
The Solana defi community worked together to create OpenBook.
