The exact direction and scope of each exchange depend on the specific integration.

Integration-ready, not one-size-fits-all

Integrations depend on available APIs, institutional agreements, technical compatibility, and applicable legislation. Each connection is scoped and agreed with the institutions involved; listing a category here does not mean an integration is already operational in a given jurisdiction.

Privacy and security

Institutional integrations must use:

  • Appropriate authorization
  • Access controls
  • Secure transport
  • Audit logging
  • Data minimization
