Unfiltered block streaming

Full Solana blocks over gRPC - every transaction, every block, no filter. Included in the PROFESSIONAL Bundle.

What it is

Standard gRPC blocks subscriptions require a non-empty account_include filter on shared plans. Unfiltered block streaming lifts that requirement: you subscribe to blocks with an empty account_include and receive every transaction in every block.

This is roughly 3,000 transactions per block, every ~400ms. Bandwidth is high - typically megabytes per block.

When to use this

Use case	Why unfiltered block streaming
HFT and MEV	You need to see every transaction to find opportunities, not just the ones matching a known filter.
Full-state indexers	You're rebuilding ledger state and can't predict which programs will be relevant.
Market-wide analytics	You're computing aggregate metrics across all activity.

If you only need transactions involving a specific program or account, regular gRPC with filters is cheaper and lighter.

What's included

• Full blocks stream with empty account_include filter, returning every transaction in every block.
• All commitment levels - processed, confirmed, finalized.
• Standard Yellowstone gRPC interface, same as the regular gRPC product.
• Authentication via the same Bundle IP allowlist as regular gRPC.

Availability

Unfiltered block streaming is included in the PROFESSIONAL Bundle - it is not a paid add-on and not sold separately. Lower tiers use regular filtered gRPC.
