Blockchain Protocol Warning
Important warning to the user: Our technical architecture relies on distributed ledger technologies (Blockchain). The user is informed that:
  • Their Public Key (Wallet Address) is considered pseudonymous data (indirect personal data).
  • When a transaction is executed on a public (e.g., Polygon, Ethereum) or permissioned blockchain, the recorded data (sender address, recipient address, timestamp, amount/quantity of energy) becomes technically unerasable and immutable.

By using our Web3 services, the user expressly consents to the data strictly necessary for the operation of the "Smart Contract" being permanently recorded on the blockchain.

Impact RGPD :Consequence on the Right to be Forgotten: The right to erasure (Art. 17 GDPR) can only apply to data stored on our centralized servers ("Off-chain" SQL databases). It cannot technically apply to data anchored on the blockchain ("On-chain").

| 5. Data Recipients

Your data is transmitted exclusively to the following recipients:

  • •Internal: Authorized SNXT INFRASTRUCTURES personnel.
  • •Technical Subcontractors: Hosts (e.g., AWS, OVH), identity verification providers, Smart Contract auditors.

Regarding your private keys (access to your digital assets): SNXT INFRASTRUCTURES never stores your private keys (default "Non-Custodial" mode), unless explicitly stated otherwise in the context of a mandated custody service.
