The 1inch Limit Order Protocol allows for conditional execution of orders based on price discovery formulas, with arbitrary callbacks that can execute actions before funds are debited. It defines an order structure with a signature, amounts, and a threshold. Orders are executed by first validating the signature and checking if the timestamp and nonce conditions are met, then calling getMakerAmount/getTakerAmount and executing any callbacks before transferring funds from the maker's account. The protocol interacts with smart contracts to validate signatures and execute the order.

1. 1inch Limit Order Protocol
- conditional execution (valid / invalid)
- arbitrary price discovery (you can use any formula for exchange)
- custom callback during the execution (perform any actions before debiting
funds from your account)

2. Order structure

3. Order execution
order: filled order structure
signature: signedTypedData_v4 signature for makerAddress = wallet (and any data for makerAddress = smart contract)
makingAmount: amount of makerAsset that you want to buy from maker (if > 0 then takingAmount should be 0)
takingAmount: amount of takerAsset that you want to sell to maker (if > 0 then makingAmount should be 0)
thresholdAmount: min return

4. Predicate - condition
nonceEquals and timestampBelow

5. getMakerAmount / getTakerAmount
Default functions:
Execution:

6. Execute predicate / getMakerAmount / getTakerAmount on a separate contract

7. makerAddress == smart contract
In the case of makerAddress = = smart contract address (your strategy), you should implement isValidSignature function
signature can be any data (not necessarily a real signature)
Example:

8. Interaction - any action before transferFrom maker funds
