Ajna RFQ orders for secondary lenders LP position market

DISCLAIMER: This smart contract is provided "as is" and has not undergone a formal security audit. Use at your own risk. The developers are not liable for any losses, damages, or vulnerabilities that may arise from using this contract. Users are advised to review the code and perform their own security assessments before interacting with the contract.

How it works

Whenever Ajna lenders can't or don't want to use the primary market for exiting their LP positions, they can instead set up an RFQ order for selling their position with a small discount to the primary market.

Setting up an order involves few steps:

1. Approve an RFQ contract to transfer LP on behalf of the maker.
2. Sign an EIP-712 order message with ECDSA/ERC-1271 signature.
3. Send the order information to the off-chain order book.
4. Wait for takers to come and fill the order.

Protocol also support inverse orders, where maker sets an RFQ order to buy Ajna LP in the particular pool with discount using their quote tokens. In such orders, takers will be the ones selling their Ajna LP shares.

Ajna LP approval

Approving Ajna LP shares involves two steps:

1. Call approveLPTransferors (required once for Ajna pool)
2. Call increaseLPAllowance (required after each LP transfer, e.g. after each partial fill)
