Developers integrate an Invo SDK (Unreal Engine, Unity, Godot, a Web SDK on npm, or a Python SDK on PyPI) and users carry spending power between connected experiences. Invo is not a crypto or blockchain platform: it is conventional financial infrastructure with a centrally operated ledger. Revenue model, with no upfront or setup fee: every card payment Invo processes (coin purchases, card sales, subscription charges) carries a card fee paid by the partner and never added to the player's price, 4.5% + $0.30 on the Open tier or 5.5% + $0.50 on the Merchant of Record tier, plus 1.5% of the listed price for cards issued outside the US, with fraud screening and a chargeback guarantee included; a 10% fee per cross-network transfer, split 3.5% to the origin, 3.5% to the destination, and 3% to Invo; and 10% of item purchases made with coins. On Open the partner is the seller and handles its own tax; on Merchant of Record (on approval) Invo is the seller and handles tax.
