Authentication

Blockspace is not a single-key gateway. Each product has its own access model — pick the one you're using and follow that quickstart.

ProductHow you authenticateProvisioned in
ShredStreamgRPC x-token metadata, per subscriptionDashboard, self-serve
Direct ShredsSource-IP allowlist on a dedicated linkDashboard, ~30 min provisioning
SWQOSNo token — open endpoint; tip transfer in the tx (HTTP) or QUIC keypair allowlistDashboard, self-serve (both HTTP and QUIC)
Relayer/TPUToken + signing-pubkey allowlist, application-basedApplication review

There is no single account-level "API key" that unlocks every product. Tokens and allowlists live next to the product they govern.

Where to get credentials

  1. Sign in to the dashboard.
  2. Subscribe (or apply, for application-gated products).
  3. Open the product page — the connection details (endpoint, token, region, allowlist form) are on that page.

Rotating credentials

Each product page has its own rotate flow. For token-based products, generate a new token, deploy it, then revoke the old one — both remain valid during the swap so there's no downtime.
