What is CoreCast and how is it different from raw gRPC?

CoreCast is Bitquery's low-latency binary Protobuf gRPC stream for Solana. Unlike raw Geyser or JSON-RPC feeds that hand you undecoded account updates, CoreCast delivers parsed, structured events — DEX trades, token launches, transfers and balance updates — already decoded across every Solana program.

How fast are CoreCast Solana streams?

CoreCast delivers events in under 100ms end-to-end — faster than WebSocket or Kafka feeds — because it streams binary Protobuf over gRPC straight from the head of the chain, with no JSON parsing in the path.

How does CoreCast compare to Geyser / Yellowstone gRPC?

Geyser and Yellowstone gRPC require you to run a validator and a Geyser plugin, then decode raw account and slot updates yourself. CoreCast is a hosted stream that already decodes every program into structured DEX trades, transfers and instructions — you subscribe and act, with no node to operate.

Which Solana data can I stream with CoreCast?

DEX trades (Raydium, Orca, Meteora, Pump.fun, Jupiter), new token launches, SPL and SOL transfers, balance updates, decoded program instructions, and slot / block headers — all on the Solana V2 schema (DEXTrades, Transfers, Instructions, TokenSupplyUpdates).

Do I need to run a validator or RPC node?

No. CoreCast is fully hosted — there is no validator, Geyser plugin or RPC node to operate. You connect to the gRPC endpoint with an API key and subscribe to the streams you need.

How do I set up a CoreCast gRPC stream?

Create a free API key at account.bitquery.io, then connect your gRPC client to the CoreCast endpoint and subscribe with a Protobuf message. The introduction guide has copy-paste examples in Go, Python and TypeScript.

Solana gRPC Streams via CoreCast Protobuf

The lowest-latency way to read Solana. CoreCast streams every program — Raydium, Pump.fun, Orca, Meteora, Jupiter — as binary Protobuf over gRPC, so trades, launches and transfers hit your bot in milliseconds. No validator, no Geyser plugin, no JSON tax.

Forget the validator

Running your own Solana stream is a second full-time job.

A Geyser/Yellowstone plugin means a voting validator, hundreds of GB of state and a decoder per program — just to see the data. CoreCast hands you decoded events.

Bitquery does the hard work of parsing blockchain transaction data into a usable form so that we don't have to. We use their interface to diagnose issues with complex transactions and their analytics as a starting point for our own.

They proved they had the technology to deliver sophisticated data solutions. We extended our support through the Binance X fellowship — building an open-source library of visualization widgets on their blockchain data.

The complex raw data is available at different levels of detail and from different viewpoints — whether we need simple aggregated transfers or parameters for failed contract calls. The support is responsive, friendly and quick.

Backend Developer, Blockpit

Partnering with Bitquery has been highly cost-effective — leveraging their established infrastructure rather than building our own let us rapidly expand our blockchain support and reach a much broader segment of on-chain users.

Nick Christie

Co-Founder, Syla

Bitquery's products are very intuitive and easy to use. We currently use their products to obtain DEX-related trading and liquidity information, which saves us the manpower and tedious technical details required to develop our own system. Their excellent technical team deserves special praise; they provide near-24/7 support and resolve issues quickly. I greatly appreciate their products and work ethic.

What is CoreCast?

CoreCast is Bitquery's low-latency Solana stream — decoded on-chain events delivered as binary Protobuf over gRPC, so you read trades, launches, transfers and balances in milliseconds without running a validator.

How low is the latency?

CoreCast targets sub-100ms from slot to your socket. Binary Protobuf avoids the JSON serialization overhead that slows other feeds.

How is this different from Geyser / Yellowstone?

Geyser plugins require you to run and vote a validator and decode each program yourself. CoreCast is fully managed and hands you already-decoded, typed events — no node, no parsers.

Which programs and data are covered?

Raydium, Pump.fun, PumpSwap, Orca, Meteora and Jupiter trades, plus new token launches, transfers, balance updates and slot/block data — all decoded.

Can I replay missed data?

Yes. Use the Kafka channel for guaranteed delivery and offset replay, and GraphQL for historical backfills on the same schema.

How do I get started?

Grab a free API key at account.bitquery.io, then connect to corecast.bitquery.io with the Protobuf schema from the docs.

Stream Solana in milliseconds.

Free API key, every program decoded, no validator to run. Connect to CoreCast and react to the next slot.
