Welcome to Surflux

Surflux is a reliable, high-performance, developer-first infrastructure platform for Sui. It's the only infrastructure service you need to deliver complete user experiences on Sui — the world's global coordination layer.

Surflux removes the pain of raw RPCs, indexing, and off-chain data plumbing, letting developers ship faster.

Developers use Surflux to build:

  • DeFi protocols that need reliable pricing and liquidity data
  • NFT-powered experiences with instant metadata and ownership tracking
  • Real-world asset (RWA) solutions that bridge on-chain and off-chain worlds
  • Real-time applications powered by instant blockchain event streams
  • Innovative new primitives that push the Sui ecosystem forward

Surflux provides the tools to do all of this faster and smarter.

1. Flux Streams​

Real-time events streaming directly from the Sui blockchain. Powers numerous use-cases without relying on RPCs — build reactive apps, track specific on-chain activity, and automate workflows based on blockchain state changes.

Package Events

Track events from specific Sui packages for protocol monitoring and analytics

Address Events

Monitor events and activities for specific Sui addresses in real-time

Object Changes

Track changes to specific Sui objects and their properties as they happen

2. Deepbook Flux Stream​

Real-time events streaming directly from DeepBook pools. Stream live trades and order book updates as they happen on-chain, powering trading dashboards, data analytics, and real-time market monitoring.

Live Trades

Stream real-time trade executions with price, quantities, fees, and order IDs

Order Book Depth

Receive live bid and ask levels with quantities and order counts for depth charts

3. Deepbook Indexing API​

The Deepbook Indexing API provides read access to DeepBook, a decentralized Central Limit Order Book (CLOB) built natively on Sui. Query pool metadata, order book depth, historical trades, and OHLCV data to power trading interfaces, analytics dashboards, and market-making strategies.

Get Pools

Retrieve all Deepbook pool metadata including base/quote assets and pool parameters

Order Book Depth

Get current bids and asks with quantities and price levels for any pool

Recent Trades

Access historical trade data with price, quantity, and timestamp information

OHLCV

Fetch candlestick data for charting and technical analysis across multiple timeframes

4. NFT Indexing API​

The NFT Indexing API exposes indexed on-chain data for the Sui network. It provides reliable, queryable access to ownership, object state, and storage relationships, covering NFT balances, Kiosk ownership, and holder data.

Address NFTs

Query all NFTs owned by a specific address with metadata and traits

NFT by Object ID

Retrieve a single NFT by its object ID with complete metadata

Collection Snapshot

Get real-time stats for any NFT collection including supply and floor price

Collection Holders

Retrieve holder distribution and ownership analytics for collections

Kiosks NFTs

Access NFTs listed in Sui Kiosks with pricing and royalty information

5. gRPC API​

Surflux supports gRPC for high-performance, type-safe communication with the Sui blockchain. Built on Protocol Buffers, gRPC enables efficient data serialization and low-latency access to blockchain data through strongly typed interfaces. It's ideal for building indexers, explorers, and applications that require real-time streaming and cross-language client development.
