How many concurrent Yellowstone gRPC streams do I get?

The Pro plan ($249/mo) includes 8 concurrent gRPC streams; higher limits are available on Business and Enterprise. Platform-wide capacity is 100+ concurrent streams.

Is Yellowstone gRPC traffic metered or billed per GB?

No. Triport plans are flat monthly subscriptions — streaming traffic is not billed per gigabyte and does not consume credits, unlike usage-billed providers that meter gRPC by traffic volume.

Which subscriptions does the stream support?

Standard Yellowstone (Dragon's Mouth) subscribe requests: accounts (with owner/account filters), transactions (by account include/exclude), blocks, block metadata, slots and entries, each with configurable commitment levels.

What you can subscribe to

Yellowstone gRPC (also known as Dragon's Mouth) is the de-facto standard for low-latency Solana data. A single bidirectional stream carries your subscribe request and delivers typed updates: account writes filtered by owner or address, transactions filtered by involved accounts, full blocks, block metadata and slot progression at processed, confirmed or finalized commitment. Existing Yellowstone clients work unchanged — point the channel at the Triport endpoint and pass your API key.

Why flat pricing matters for gRPC

Streaming is the workload where usage-billed providers get expensive fastest: a busy account stream can move gigabytes per day, and per-GB or per-credit metering turns that into an unpredictable bill. Triport meters plans by RPS and stream count only — a stream that runs 24/7 costs the same flat monthly price. See the provider comparisons for how credit-based billing models price the same workload.
