A Hedgey Puts Smart Contract is a protocol for peer to peer put options trading. Each pairs contract is unique for a single asset currency and payment currency. The Asset currency is the underlying asset that the options are written against, and the payment currency is the currency for which premiums are paid, and the strike is based on. Once a pair has been created by the factory, then anyone may create options on the contract. Hedgey Puts deal almost exclusively with the payment currency for escrow, unlike their calls counterpart.
