The Argentina-born Exactly protocol passed a testnet at ETHLatam. It is a decentralized, non-custodial, open source protocol providing an autonomous interest rate market to lenders and borrowers. Gabriel Gruber, Exactly co-founder and CEO, told CoinDesk that the protocol, setting interest rates based on credit supply and demand, will allow the users to frictionlessly exchange the time value of their assets at both variable and fixed interest rates for the first time in DeFi.
