Fetching Bet Limits

The getBetLimits method retrieves the minimum and maximum odds, as well as the minimum and maximum amounts allowed for Combo bets. By querying the blockchain, this method fetches the configuration values that define the limits for Combo bets, ensuring that users can only place bets within the allowed parameters.
This is particularly useful for ensuring compliance with system constraints and providing users with up-to-date bet limits before they place a Combo bet. The method ensures the integrity and validity of the betting process by enforcing these predefined limits.

Usage

import kohin from "./kohinInstance";

const betLimits = await kohin.getBetLimits({
  betType: "Combo", // Type of bet: "Combo" for express bet, "Single" for ordinar bet
});

if (betLimits.success) {
  console.log("Combo Bet Limits:", betLimits);
  toastify(
    `Combo Bet Limits:
    Min Odds: ${betLimits.minOdds},
    Max Odds: ${betLimits.maxOdds},
    Min Amount: ${betLimits.minAmount} USDT,
    Max Amount: ${betLimits.maxAmount} USDT`,
    "autoSuccess" // Display success message in the toast notification
  );
} else {
  console.error("Error fetching Combo Bet Limits:", betLimits.error);
  toastify(`Error: ${betLimits.error}`, "autoError"); // Display error message in the toast notification
}

The getBetLimits method returns an object with the following structure:
