4. Pyth , a blockchain oracle protocol , has officially launched its newest product, Express Relay , on mainnet, according to the team: “The launch introduces a novel decentralized solution to the long-standing problem of MEV in processing liquidations and market-efficiency enhancing transactions in DeFi – once thought to be an inevitable characteristic of on-chain finance. The primitive connects DeFi protocols directly with a network of established searchers through protocol-controlled auctions for events like liquidations. Searchers who have already integrated include Flow Traders, Wintermute, Auros, Flowdesk, Caladan, Tokka Labs and Swaap Finance.”
