gRPC
Real-time Yellowstone gRPC streaming with rich filters. The recommended interface for trading bots, indexers, and any high-throughput workload.
// updated 2026-08-26
Real-time streaming of Solana blockchain data via the standard Yellowstone gRPC interface.
Region: gRPC is served from Frankfurt (FRA) only - the gRPC endpoint has no other region.
Running an automated trading strategy? gRPC is almost certainly what you need - higher throughput, more granular filtering, and lower per-event latency than WebSocket.
What it's for
Trading bots, market makers, indexers, and analytics systems use gRPC to react to on-chain events with minimal latency.
When should I use gRPC instead of WebSocket?
| You need... | Use this |
|---|---|
| Real-time streams of on-chain events | gRPC (this product) |
| On-demand queries (balances, transaction history) | RPC |
| Lightweight subscriptions for browser apps | WebSocket |
| Entire blocks streamed (HFT, MEV) | gRPC + unfiltered block streaming |
Endpoints
| Type | URL |
|---|---|
| gRPC | fra.sol.supanode.xyz:10010 |
Frankfurt region. Authenticate with your token in the x-token header (or Authorization: Bearer) - see Authentication.
What's included
- Standard interface: Yellowstone gRPC - the open-source streaming standard maintained by Triton One.
- Subscription types: accounts, transactions, slots, blocks, blocks_meta, entries.
- Commitment levels: processed, confirmed, finalized.
- Token auth - the same token as RPC and WebSocket, sent as
x-tokenon the connection. - Unlimited, unmetered throughput - no per-MB or per-credit billing on the data your streams deliver, on every gRPC tier.
Throughput is unlimited and unmetered. Supanode bills by plan tier, so stream data carries no per-MB or per-GB charge. What scales by plan is your concurrent subscription count and the total addresses you can watch - see Limits.
For the full list of streams and parameters, see What's available.
Pricing
gRPC is included in 4 of the 5 Bundle plans. What scales by tier is how many subscriptions you can hold at once and how many addresses you can watch in total. Separately, the node caps every filter at 2 000 addresses and every subscription at 10 filters, so a large address budget has to be spread across several filters and subscriptions - Limits shows the layout for each plan.
| Plan | Concurrent subscriptions | Max accounts watched |
|---|---|---|
| STARTER | not included | — |
| FOCUS | 1 | up to 100 |
| BUILD | 10 | up to 5,000 |
| GROW | 20 | up to 24,000 |
| PROFESSIONAL | 50 | up to 100,000 |
STARTER ($40/mo) is WebSocket-first - no gRPC. For gRPC start at FOCUS ($99/mo).
Throughput on every gRPC tier is unlimited and unmetered. For full per-stream caps see Limits; for the full plan comparison see Plans.
