Geyser gRPC / Fastlane
100% compatible with standard Yellowstone Geyser gRPC — Regular Geyser and Fastlane
Shreder Geyser gRPC / Fastlane is 100% compatible with standard Yellowstone Geyser gRPC (same protocol, protos, filters, and clients).
Point any Yellowstone gRPC client at a Shreder endpoint and keep your existing subscription logic. You get structured Solana updates for transactions, accounts, slots, blocks, and metadata.
Regular Geyser vs Fastlane
| Mode | What it is |
|---|---|
| Regular Geyser | Standard Yellowstone Geyser gRPC for reliable production streaming |
| Fastlane | Shreder’s accelerated implementation of the same Yellowstone Geyser gRPC interface — typically 2× faster delivery, no client changes |
Fastlane is not a separate data format. Change endpoint (and token) only — filters, protos, and stream types stay the same.
In GeyserBench Fastlane uses kind = "yellowstone".
What you can subscribe to
Standard Yellowstone stream types, including:
- Transactions
- Accounts (exact account, owner, memcmp, data-size, optional data slices)
- Slots
- Blocks and metadata
Keep subscriptions focused on the data your backend needs.
Usage
- Get a Shreder Geyser gRPC / Fastlane endpoint from the console or contact.
- Use any standard Yellowstone gRPC client.
- Keep your existing
SubscribeRequestfilters.
When to use it
- You already run Yellowstone gRPC clients
- You need post-execution context (state, logs, balances, outcomes)
- You want structured multi-stream subscriptions (accounts + slots + transactions)
For earlier pre-execution Shred Streams, see Decoded Shreds or Binary.
