Agentic Payments / Facilitator: The AllUnity Facilitator does not hold or take possession of user funds and does not have access to users’ private keys. It cannot independently initiate a transfer or modify the amount, recipient or other parameters of a payment authorization already signed by the user. The Facilitator technically verifies the signed authorization and, following successful verification, submits it unchanged to the relevant smart contract for execution.

The White Papers under Art. 51 MiCAR have been published with all material information, including the EMT holders’ redemption right, information on the risks and the mandatory information on principal adverse impacts on the climate and other environmental-related adverse impacts of the consensus mechanism.

The White Papers are available at: allunity.com/whitepapers.

In the event of any inconsistency or discrepancy between the PDF and XHTML formats in AllUnity White Papers, the PDF versions shall prevail.

Redemption Right: Pursuant to Article 49 MiCAR, the holders of EMTs have a statutory right of redemption against AllUnity at any time and at par value.
