Metronome

Metronome is continuing its journey by relaunching and innovating for DeFi in 2022. Metronome was a pioneer in the DeFi space when it was launched in June 2018. With an elegant system of four smart contracts, Metronome has had success with its daily auctions and DEX functionality. Since Metronome’s launch, DeFi has evolved due to the composable nature of protocols.
