LooksRareProtocol
This contract is the core smart contract of the LooksRare protocol ("v2"). It is the main entry point for users to initiate transactions with taker orders and manage the cancellation of maker orders, which exist off-chain. ~~~~~~ ~~~~ ~~~~ ~~~ ~~~ ~~~ ~~~ ~~~ ~~~ ~~~~~~~~~ ~~~ ~~~ ~~~~~~~~~ ~~~ ~~~~~~~~~ ~~~~ ~~~~ ~~~~~~~~~ ~~~ ~~~ ~~~~~~~ ~~~~~~~ ~~~ ~~~- ~~~~~~~~ ~~~~ ~~~ ~~~~ ~~~~ ~~~ ~~~ ~~~~~~~~~~~~ ~~~~~~~~~~~~ ~~~ ~~~ ~~~~~~~~~~~ ~~~~~~~~~~~ ~~~ ~~~ ~~~ ~~~ ~~~ ~~~ ~~~ ~~~~~~~~~~ ~~~ ~~~ ~~~~~ ~~~ ~~~~~~ ~~~~~~ ~~~ ~~~~~ ~~~~~~~ ~~~ ~~~ ~~~ ~~~ ~~~~~~~ ~~~~~~ ~~~~ ~~~ ~~~ ~~~~ ~~~~~~ ~~~~ ~~~ ~~~ ~~~ ~~~ ~~~~ ~~~ ~~~ ~~~ ~~~ ~~~ ~~~ ~~~~ ~~~ ~~~ ~~~ ~~~ ~~~~ ~~~~~~ ~~~~ ~~~ ~~~ ~~~~~ ~~~~~~ ~~~~~~~ ~~~ ~~~ ~~~ ~~~ ~~~~~~~ ~~~~~ ~~~ ~~~~~~ ~~~~~~ ~~~ ~~~~~ ~~~ ~~~ ~~~~~~~~~~ ~~~ ~~~ ~~ ~~~ ~~~ ~~~ ~~~ ~~~~~~~~~~~ ~~~~~~~~~~~ ~~~ ~~~ ~~~~~~~~~~~~ ~~~~~~~~~~~~ ~~~ ~~~ ~~~~ ~~~~ ~~~ ~~~~ ~~~~~~~~ ~~~~ ~~~ ~~~~~~~ ~~~~~~~ ~~~ ~~~ ~~~~~~~~ ~~~~ ~~~~ ~~~~~~~~ ~~~ ~~~~~~~~~ ~~~ ~~~ ~~~~~~~~~ ~~~ ~~~ ~~~ ~~~ ~~~ ~~~ ~~~~ ~~~~ ~~~~~~

incrementBidAskNonces​
function incrementBidAskNonces(bool bid, bool ask) external nonpayable
This function increments a user's bid/ask nonces.
The logic for computing the quasi-random number is inspired by Seaport v1.2. The pseudo-randomness allows non-deterministic computation of the next ask/bid nonce. A deterministic increment would make the cancel-all process non-effective in certain cases (orders signed with a greater ask/bid nonce). The same quasi-random number is used for incrementing both the bid and ask nonces if both values are incremented in the same transaction. If this function is used twice in the same block, it will return the same quasiRandomNumber but this will not impact the overall business logic.
Parameters​

|---|---|---|
| bid | bool | Whether to increment the user bid nonce |
| ask | bool | Whether to increment the user ask nonce |
