Figures supplied by Mes Potos, September 2026. A social result is assessed through a method, on a given population and period.
Context
A solidarity contribution raises three questions: what is it used for, how does it reach the person concerned, and what can be said about it afterwards to the contributor? Cash moves without a trace, a transfer leaves the funds at the free disposal of whoever receives them, and the record of a prepaid voucher remains the one declared by its issuer. The earmarked account seeks both at once: value that can be used with dignity, framed by rules written before the spend, and immutable proof of the payment.
The roles stay distinct. MAP issues the earmarkable digital euro, holds the digital euro account rules, checks every operation before execution and records the payments on the blockchain. The organisations that follow the people assess their situation, decide whether they join and what budget they receive, and support them. The journey is in service, public since November 2024.
The journey, from contribution to payment
The contributor pays in funds in euros for a specific use, through a donation, a fundraising pot or corporate giving. MAP issues the matching earmarkable digital euro, one for one. The organisation allocates an account and means of payment to the user, card and QR code. The user pays at an authorised supplier, and the accepted payment is recorded on the blockchain with its amount, its supplier, its date and the rule applied, for every party, MAP included.
-
Contribution
A contributor pays in funds in euros for the defined use: a donation, a contribution to a fundraising pot, a corporate giving budget.
Role: funder or contributor.
-
Issuance
MAP issues the matching earmarkable digital euro, one for one, and allocates it to the digital euro account. Issuance follows receipt of the funds.
Role: MAP.
-
Allocation
The organisation supporting the person decides whether they join and what budget they receive. They get an account with an IBAN and their means of payment, activated immediately.
Role: the organisation supporting the person.
-
Payment
The person pays a selected supplier, in store, online or by QR code, within the area, period and ceilings provided for. The operation is checked before execution; a refusal keeps its reason, given straight away.
Role: user, then supplier.
What each role sees
| Role | What they are shown |
|---|---|
| Contributor | The use of their contribution, payment by payment. |
| Organisation | The budgets allocated, the payments, the statuses and the reasons for refusal of the people it supports. |
| User | Their balance, their payments and the reason for a refusal concerning them. They pay like anybody else, with an account, a payment card and a QR code. |
| Supplier | The payments they have taken. |
Conditions of transposition
What transposes
- Issuing an earmarkable digital euro from funds received, one for one.
- Writing the rules before the first payment, and checking them before every operation.
- Equipping a user with an account and means of payment: card, transfer, QR code.
- Recording every payment on the blockchain and showing it to each role.
What has to be re-examined
- The origin of the funds and the collection set-up, which differ from one digital euro account to the next.
- The obligations to account for the money, specific to your organisation.
- The volumes, the rhythms and the suppliers expected.
- The systems to be integrated, and the rules your digital euro account will call for.
