Your First Request
Blockspace isn't a single subscription. Each product has its own access model, timeline, and entry point. Pick the row that matches your situation.
| Product | What it is | How to start | Time to first call |
|---|---|---|---|
| ShredStream | Stream Solana shreds before slot confirmation | Start free → self-serve | minutes |
| Direct Shreds | Dedicated IP, your bandwidth alone | Provision → — provisioning ~30 min | ~30 min |
| SWQOS | Stake-weighted priority lane (HTTP RPC) | Enable → — public endpoint, no key | minutes |
| SWQOS QUIC | Stake-weighted priority lane (QUIC, signed) | Subscribe or trial → — self-serve, add pubkey in dashboard | minutes |
| Relayer/TPU | MEV mempool + bundle relay, pay-on-profit | Apply → | days (application review) |
Self-serve products (ShredStream, SWQOS HTTP, SWQOS QUIC, Direct Shreds onboarding) provision in the dashboard. Application-gated products start with an email to support-blockspace@everstake.one.
After provisioning
The product page in the dashboard shows the connection details — endpoint URL, region, and the authentication method that product uses (token / source-IP allowlist / signing-pubkey allowlist / on-chain tip). See Authentication for the full matrix.
Then jump straight to the product quickstart with copy-paste examples:
- ShredStream Quickstart — gRPC client, x-token metadata
- Direct Shreds Quickstart — UDP receiver against your allowlisted IP
- SWQOS Quickstart — HTTP send with tip instruction (or QUIC with signing keypair)
- Relayer/TPU Quickstart — gRPC push to a Block Engine you operate, plus TPU-direct bundle submission
