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.
| Product | How you authenticate | Provisioned in |
|---|---|---|
| ShredStream | gRPC x-token metadata, per subscription | Dashboard, self-serve |
| Direct Shreds | Source-IP allowlist on a dedicated link | Dashboard, ~30 min provisioning |
| SWQOS | No token — open endpoint; tip transfer in the tx (HTTP) or QUIC keypair allowlist | Dashboard, self-serve (both HTTP and QUIC) |
| Relayer/TPU | Token + signing-pubkey allowlist, application-based | Application 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
- Sign in to the dashboard.
- Subscribe (or apply, for application-gated products).
- 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.
