Tersign Sub-processors
Last updated 12 October 2026. This list is incorporated into the Data Processing Addendum. We update it before adding a sub-processor; material changes are announced per DPA Section 6.
| Sub-processor | Purpose | Location of processing |
|---|---|---|
| Cloudflare, Inc. | Hosting and edge infrastructure for the ledger, storage (Workers, D1, R2), network security | Global edge network (EU/US data-center processing; Cloudflare DPA with SCCs) |
| Stripe, Inc. / Stripe Payments Company | Fiat payment processing and billing (acts as an independent controller/processor for payment data under its own terms) | US / global |
| AI model providers (currently: Anthropic, PBC) | Operating the service: support correspondence and operational tasks, such as answering a support request or investigating an incident. Never the ledger's code path: no model writes, counter-signs or adjudicates a Record, and dispute triage is deterministic (Terms §12.1) | US |
No other third party receives Customer personal data. On-chain anchors contain cryptographic digests only — never personal data.
