A Helius Alternative for Unmetered Yellowstone gRPC

Helius is excellent for a deep dApp API layer. But if all you need is a raw, unthrottled Yellowstone gRPC firehose and you keep hitting credit limits, a flat-rate unmetered endpoint can be a simpler, cheaper fit.

When to switch

Switch when your usage is dominated by streaming, when credit accounting is making your bill unpredictable, or when you are rate-limiting your own bot to stay under a plan. The Yellowstone protocol is identical, so switching is a one-line endpoint change.

What you keep, what you drop

You keep the standard gRPC interface, the same client code, the same filters. You drop the credit meter and the per-request caps. You also drop the richer enhanced-API layer — if you rely on parsed transactions or webhooks, keep those on a specialist provider and use the unmetered endpoint just for the raw stream.

Migrating in one line

Point your existing client at the new endpoint and swap the token. No SDK migration, no rewrite:

let channel = Channel::from_shared("http://YOUR_ENDPOINT:10000")?
    .connect().await?;
// x-token interceptor stays the same; only the URL and token change

FAQ

Is my client code compatible?

Yes. Any standard Yellowstone gRPC client (Rust, Python, TypeScript) works by changing the endpoint URL and x-token.

Can I run both in parallel?

Yes. Many teams keep an enhanced-API provider for parsed data and add an unmetered endpoint for the raw high-volume stream.
