Racer.loans is a protocol that's all about getting exposure on friend.tech keys in a capital efficient way. Racer is currently in "borrow-only mode" where users can purchase a vaulted key for a fraction of the full key price. E.g. assuming the value of a key is 5 ETH and the margin is set at 30%. User only have to pay an upfront cost of 3.5 ETH (borrowing 1.5 ETH) in order to get exposure to the key -saving yourself 1.5 ETH upfront.
