Hello, I would like to suggest a "Fee" Extension in the Fabric Contracts, for the marketplaces, that could apply: (1:) to the Constructor, when a user deploys the Contracts, the fee is sent to the wallet adress of marketplace owner (Example 0.1 matic). (2:) Also a Recurrent Fee (Example: 0.01 Matic)for every transaction done to that contract when a users mint, or re -sale the tokens. The fee amount should go directly to the Wallet adress of the Marketplace owner, so there is no need to "Withdraw" from each contract 1 per 1, and should not be editable for the deployer of the contract, at least in the deployer dashboard. Also, the fee should be charged on top of the final Buyer, so the "user deployer" continues to receive 100% of his expected revenue/royalty and fee is charged to the buyer. This will help marketplaces monetize when users deploy tokens from their platforms.
