Our principles
The solidarity lottery is a fundraising tool for the association, never a commercial gambling product. Tickets are paid in time and the whole contribution is reinvested in our missions.
Solidarity lottery
Verify the draw
The draw seed is sealed before the first participation and revealed afterwards. Every ticket is fingerprinted in a public Merkle tree, so you can recompute the result yourself.

Principles, conditions and fairness
Conditions of participation
Open to adults according to the rules of the selected country. Tickets per person are capped, tickets are personal and non-refundable.
Fairness of the draw
A random seed is sealed before sales open and we publish its SHA-256 fingerprint. At closing, all tickets are aggregated into a published Merkle root. Anyone can recompute the result.
Nobody can influence the outcome
Neither the association, nor the author of the platform, nor a partner can alter the sealed seed, remove a sold ticket or pick a winner. Every action is timestamped in the public audit log.
