Identity, control, and evidence. Independently verifiable.
DinClient supports identity registration/lifecycle, organizations, support, developer applications/keys/webhooks, credential issuance/presentation and audit checkpoints. Server callers must provide their authenticated cookie and CSRF token; Node does not maintain a browser cookie jar.
Use viem for Ethereum EIP-712 wallet approvals. Credential helpers use WebCrypto Ed25519 with client-held JWKs. Never send a private JWK to the API.
Use verifyAnchoredEvidence, verifyAuditCheckpoint and verifyWebhookSignature. A webhook receiver must implement durable delivery-ID deduplication in its own transaction.

// Owner reads require your session; do not place server credentials in a bundle.
