CoreCast : Smart Solana gRPC
CoreCast delivers ultra-low latency Solana gRPC streams with parsed, filterable events for real-time trading apps.
What is CoreCast?
CoreCast is Bitquery’s Smart gRPC stream for Solana, delivering ultra-low latency, parsed, and filterable events. Get trades, transfers, balances, and liquidity updates enriched with context — ready to power real-time trading, DeFi apps, terminals, and bots without parsing overhead
Why Smart gRPC Streams?
Ultra-low latency
Lightning-fast event delivery.
Context-aware
Each event comes enriched with token, balance, and program metadata.
Efficient
Subscribe only to the events you need.
Simple integration
Strong Protobuf contracts, stable schemas.
Broad protocol coverage
All major Solana protocols supported, with new ones added continuously.
Topics You Can Stream
Transactions
- Finalized transactions with parsed instructions, logs, and status
Transfers
- All token transfers with token context and instruction logs
Balances
- Balance and balance updates for tracked accounts and mints
DEX Trades
- Swaps and trades across supported protocols with token balance post swap
DEX Orders
- Order lifecycle events including order book data, pool balance across Serum, Openbook, and other DEXs
DEX Pools
- Pool creation, updates, liquidity changes, and pool balance
Context-Aware Filtering
Filters are required to subscribe — ensuring your stream is lightweight and preciseYou can filter by :
- addresses (senders, receivers, owners, program IDs)
- tokens (mints like WSOL, USDC, SPL standards)
- value thresholds (min amounts in native or token units)
- markets/pools (DEX protocols, pool IDs, markets)
Filtering is applied server-side, reducing bandwidth and speeding up processing.

Trusted by the leading organizations in Web3
Low Latency Data Streams through Kafka and CoreCast
Feature / Stream
Websocket
Kafka
CoreCast (Smart gRPC)
Latency
~1 second (network + parsing overhead)
< 500 ms (sub-second)
< 100 ms (ultra-low latency)
Filtering
Most powerful: addresses, tokens, pools, value thresholds, USD
Available: addresses, tokens, pools, thresholds (not as rich as WebSocket)
USD Values
Built-in
(Available in different topic)
(planned)
Reliability
Auto-reconnect via GraphQL, but no replay
Retention available, replay from checkpoints
Query GraphQL, no replay support
Retention / Replay
Yes, configurable retention window
Schema / Data Format
JSON over WebSocket
Avro/Protobuf over Kafka
Protobuf (typed contracts)
Delivery Guarantees
At-most-once
At-least-once (can configure exactly-once)
At-most-once
Integration Complexity
Easiest for frontends, explorers, bots
Requires infra (Kafka cluster, consumers)
Lightweight, good for backend apps and trading engines
Bandwidth Efficiency
Medium (JSON, more verbose)
High (binary encoding, batching)
Medium (binary Protobuf, direct streams)
Use Case Fit
Dashboards, explorers, analytics needing USD values & rich filters
Mission-critical infra: indexing, ETL pipelines, archival, guaranteed delivery
Ultra-low latency trading, real-time DeFi apps, terminals, Telegram bots

FAQ
Raw gRPC delivers unparsed transaction data. CoreCast delivers parsed, enriched, filtered events.
Comparable to leading Solana streaming providers, but with parsed events.
Yes. Filters are mandatory and server-side applied for efficiency.
