​
Overview

You can set purchase limits for specific wallet addresses. These are included as fields in the purchase permit, and must be validated by your contract. See the Smart Contract Guide for implementation details.

​
Purchase Limits

  • minAmount: Minimum purchase amount per wallet.
  • maxAmount: Total purchase limit per wallet.
You can set a default minimum and maximum as well as per-wallet minimum and maximums in the Echo Founder Dashboard.

​
Price Limits

For sales with a dynamic pricing model where the user can commit with a requested price (e.g. auctions), you might want to set a minimum and/or maximum bid price.
  • minPrice: Minimum bid price per wallet.
  • maxPrice: Maximum bid price per wallet.
You will need to contact the Sonar team if you want to use this feature.
