Putty

Putty is an exotic options market for NFTs and ERC20s

Links:

Note:

These contracts are very simple. All logic is contained in the single contracts/Putty.sol file.

Flow:

A buyer creates an off-chain option order, signs it and then a seller fills that option order on-chain. The only data stored on-chain is the hash of option details (strike, duration, etc.). When an option is exercised/expired, the user submits all of the order details and the hash is then derived and verified on-chain.

Installation
