This contract stores updates of different values, that are updated by keeper bots, who are incetivized to do this based on the reward assigned by the person who requested the updates.

Basic Concept:

• The main contract stores the updates, requests and the logic around it.
• To update value, you need to launch the second contract, which basically acts as a middleware, that will contain the function get_new_value that will be called by the updaters through the main contract.
• Then call the register_request function in the main contract, which'll create the request that updaters can read and decide whether they want to keep updating this value(based on the reward amount).

Usage

• Look into template_exmaple.cairo in current directory
• Create contract that contains get_new_value function which returns single felt
• Launch the contract you just created and store it's address
• Call register_request in main contract with following arguments:
  • maturity -> by what block timestamp do you need the terminal value
  • requested_address -> address of your middleware contract containig get_new_value function
  • reward_token_address -> address of the token which'll be used for reward paid to the keeper
  • reward_amount -> amount of said token
• Wait for expiration and read the terminal value
