The method sets prices for the sale of ERC-20 tokens that will be sold through wNFT placed on the Kiosk. Multiple types of ERC-20 tokens can be simultaneously sold on the Kiosk. They just need to be added to the wNFT Collateral and placed on the Kiosk. Only the Kiosk owner can invoke this method.

IMPORTANT: In this example contract model, only the ERC-20 tokens that were added to wNFT first (the 1st token record in the wNFT Collateral array) are considered as the ones being sold with prices and discounts.

The method emits a CollateralPriceChanged event for each record in the provided array of prices, with the following details:

• The SHA-256 hash of the Kiosk name on which the wNFT is placed.

• The address of the smart-contract of the ERC-20 token being sold.
