I would like to suggest a Dexkit Soulbound NFT (Non transferable after the purchase) to unlock all features. This NFT should give to Marketplace owners that are not interested in re-sell the tokens, the possibility to unlock all the features and all the fees in any chain, in a cheaper price. For Dexkit, the funds will go directly to the Devs and will not worry of people re selling and cashing back the tokens in future.
