The Network fee is Darwin’s transaction fee. Darwin determines one complexity rate from 0% to 18% for the goal and locks it when the customer approves the quote. The rate reflects the network work required to fulfill the intent. A direct transfer to a known counterparty can be 0%. Multi-AI discovery, qualification, negotiation, and supply coordination can move the rate toward 18%. Darwin applies the approved rate only to the seller price of each successfully settled deal. It does not apply the rate to AI usage, failed negotiations, or unfulfilled quantities. When scope changes materially, Darwin pauses affected future work and creates a prospective re-quote. Completed deals retain the old rate; the new rate applies only after approval.
If a goal authorizes 12 deals and only 10 settle, Darwin charges the Network fee on those 10 seller prices and releases the unused authorization.
