CoreCast is Bitquery's ultra-low-latency multi-chain gRPC stream. It delivers parsed, structured on-chain events — DEX trades, new token launches, transfers and balance updates — as binary Protobuf over gRPC across Solana, Ethereum, BSC, Base and Tron, with no JSON parsing in the path.

How fast are CoreCast streams?

CoreCast delivers events in under 100ms end-to-end on every chain — 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 running my own validators and nodes?

Reading several chains yourself means running a voting validator and Geyser plugin for Solana plus a synced archive node and decoders for each EVM chain. CoreCast is a hosted stream that already decodes every chain into structured DEX trades, transfers and instructions — you subscribe and act, with no nodes to operate.

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 on any chain. 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.

CoreCast gRPC Streams across Solana & EVM

CoreCast is Bitquery's ultra-low-latency gRPC stream for multiple chains. Decoded DEX trades, new tokens, transfers and balances stream as binary Protobuf over gRPC across Solana, Ethereum, BSC, Base and Tron — so your bot reacts in milliseconds. No validator, no node, no Geyser plugin, no JSON tax.

CoreCast gRPC is the fastest feed we ship — binary Protobuf, no serialization overhead, the same across Solana and every EVM chain. Step down to Kafka, WebSocket or GraphQL when durability or history matters more than raw speed.

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.

Jan Dreske

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 ultra-low-latency multi-chain stream — decoded on-chain events delivered as binary Protobuf over gRPC, so you read trades, new tokens, transfers and balances in milliseconds across Solana, Ethereum, BSC, Base and Tron without running a validator or node.

Which chains does CoreCast support?

CoreCast streams Solana plus EVM chains including Ethereum, BSC and Base, and Tron — all on the same Protobuf schema and the same gRPC endpoint. The Solana-only feed is also available at Solana gRPC Streams.

How low is the latency?

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

How is this different from Geyser / Yellowstone or running your own nodes?

Running your own infrastructure means a voting validator for Solana and a synced archive node plus decoders for each EVM chain. CoreCast is fully managed and hands you already-decoded, typed events across every chain — no nodes, no parsers, no per-chain ops.

Which data is covered?

DEX trades (Raydium, Pump.fun, Orca, Meteora, Uniswap, PancakeSwap, Aerodrome, SunSwap), new token launches, transfers, balance updates and block headers — all decoded on the V2 schema (DEXTrades, Transfers, Instructions, TokenSupplyUpdates).

Can I replay missed data?

Yes. Use the Kafka channel for guaranteed delivery and offset replay, and GraphQL for historical backfills on the same V2 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.
