WebSocket Streams — Zero Infrastructure, Instant Data


Subscribe to live blockchain events via WebSocket — no infrastructure needed. ~1 second latency. Track DEX trades, token prices, wallet transfers, and new token launches across Solana, Ethereum, BSC, and 40+ chains. JSON over WebSocket, browser-compatible.

Why WebSocket Streams

Zero Infrastructure

Required

JSON over

WebSocket

Filter by Token,

Wallet or Protocol

40+ Chains,

Sub-Second Latency

WebSocket vs Kafka vs RPC — Choose the Right Protocol

Feature

RPC Websocket /Geyser Plugin

Bitquery GraphQL Subscriptions

Bitquery Kafka Stream

Node/Infra Required

Yes (self-managed node)

No (cloud-managed by Bitquery)

No (cloud-managed by Bitquery)

Setup Time

High (node setup, sync, maintain)

Very Low (register & query)

Low (register, integrate Kafka client)

Data Format

Raw, binary, or gRPC

Structured, JSON (GraphQL)

Structured, Protocol Buffers

Filtering

Limited (basic filters)

Advanced (GraphQL-level filtering)

By stream/topic and schema

Data Coverage

Raw Onchain data

All Onchain data parsed (DEX, pools, etc.)

All Onchain data parsed (DEX, pools, etc.)

Unconfirmed Transactions

Limited

Yes

Yes (unconfirmed)

Historical Data

No

Yes (queryable)

No (stream only)

Latency

Low (depends on your infra)

<1s (cloud-optimized)

Sub-second, ultra-low latency

Scalability

You must scale/monitor infra

Scales automatically (SaaS)

Enterprise-grade, scales automatically

Maintenance

High (updates, patches, uptime)

None (managed by Bitquery)

None (managed by Bitquery)

Data Parsing

Developer must parse raw data

Pre-parsed & enriched (USD values, etc.)

Pre-parsed & enriched

DEX/Protocol Support

Needs custom parsing per DEX/protocol

Supported out-of-the-box

Supported out-of-the-box

Reliability/Failover

Developer’s responsibility

Managed by Bitquery

Kafka’s built-in resilience + Bitquery

Best Use Cases

Deep custom infra, full control needed

Fast prototyping, dashboards, bots

HFT, enterprise, large-scale real-time apps

Use Cases

Real-Time Price Monitoring


  • Subscribe to live token price updates across Solana, Ethereum, BSC, and 40+ chains. Power price bots and dashboards without any server infrastructure.

Wallet Activity Alerts


  • Track transfers, trades, and balance changes for any wallet address in real time. Build Telegram or Discord bots that alert on whale movements.

DEX Trade Feeds


  • Subscribe to live DEX swaps on Uniswap, Raydium, PancakeSwap, and 100+ protocols. Get structured, parsed trade data as JSON the moment it happens.

New Token Launch Alerts


  • Receive instant WebSocket notifications when new tokens launch on Pump.fun, Raydium, or any supported DEX. React faster than polling-based solutions.
