You can monetize trading by implementing blockchain-enforced trading fees.
Trading fees are charged in Enjin Coin (ENJ), set up during the asset minting process, and can be designated per item or per transfer.
Types of Trading Fees
Per Transfer: A flat fee per transaction, payable by sender to the creator. With this type of fee, you could send a million FISH for a fee of 0.1 ENJ.
Per Item: A fee per item being transferred, payable by sender to the creator. Watch out when sending APPLES. Sending 10 will cost you 10 ENJ.
Ratio Cut: A percentage of items is taken from the total being transferred from the sender and given to the creator. The number of items for the fee is rounded down. If the fee is < 1 item, the fee is 0.
Ratio Extra: A percentage of items is taken from the sender in addition to the items being traded and is given to the creator. The number of items for the fee is rounded down. If the fee is < 1 item, the fee is 0.
