  Exactly Protocol is a decentralized, non-custodial, open-source protocol providing
  autonomous fixed and variable interest rate credit markets on Ethereum, Optimism,
  and Base. It enables users to deposit and borrow crypto assets at both variable
  rates and fixed rates through maturity pools, using a continuous non-linear interest
  rate model, dynamic close factor liquidations, and a rewards distribution system
  with the EXA governance token.
