What is ChainStream
ChainStream is AI-Native infrastructure built for the Web3 era. Unlike traditional Web3 data APIs, ChainStream was designed from day one for AI Agents and automation scenarios, providing:- Unified Data Layer: One API to access multi-chain data, no need to integrate multiple vendors
- Built-in Compliance: Native KYT/KYA integration, no third-party risk control services needed
- AI Execution Layer: Let AI Agents directly operate in the on-chain world through MCP protocol
Core Capabilities
ChainStream provides three core capabilities, covering the complete chain of Web3 data acquisition, security compliance, and AI execution:Data — Real-time On-chain Data
Access multi-chain real-time data through a unified API, supporting WebSocket real-time push and historical data queries.Multi-chain Data Aggregation
Multi-chain Data Aggregation
One API endpoint to access data from Solana, Ethereum, and BSC without connecting to multiple data sources separately. Supports cross-chain queries and data standardization.
Real-time Price & Trading Data
Real-time Price & Trading Data
Millisecond-level price updates, supporting DEX/CEX aggregated prices, trading pair depth, and candlestick data. WebSocket real-time push with <2ms latency.
Smart Money Wallet Tracking
Smart Money Wallet Tracking
Track on-chain smart money movements, including whale wallets, institutional addresses, and KOL wallets. Provides wallet labels, position changes, and trading behavior analysis.
Historical Data Queries
Historical Data Queries
Supports historical data queries for any time range, including historical prices, positions, and transaction records. Data retention period varies by plan.
Security — Security & Compliance
Built-in enterprise-grade security compliance capabilities to meet the risk control needs of exchanges, wallets, and DeFi protocols.KYT (Know Your Transaction) Transaction Risk Assessment
KYT (Know Your Transaction) Transaction Risk Assessment
Real-time transaction risk level analysis, identifying suspicious fund flows. Supports OFAC sanctions list checks, mixer identification, and darknet association detection. Returns risk scores (0-100) and detailed risk labels.
KYA (Know Your Address) Address Profiling
KYA (Know Your Address) Address Profiling
Comprehensive address profiling analysis, including address type identification (EOA/contract/multisig), historical behavior analysis, fund source tracing, and associated address mapping.
Compliance Audit Support
Compliance Audit Support
Complete audit logs to meet regulatory reporting requirements. Supports exporting FATF Travel Rule format reports, integrates with mainstream compliance tools (Chainalysis, Elliptic format compatible).
AI Execution — AI Execution Layer
Let AI Agents safely interact with blockchain through MCP (Model Context Protocol).MCP Server Support
MCP Server Support
Native support for Anthropic MCP protocol, allowing Claude and other AI models to directly call ChainStream capabilities. No adapter code needed, works out of the box.
AI Agent Friendly Toolset
AI Agent Friendly Toolset
Tool interfaces designed specifically for AI Agents, including structured output, error self-healing, and context preservation. Supports mainstream frameworks like LangChain, AutoGPT, and CrewAI.
Natural Language to On-chain Operations
Natural Language to On-chain Operations
AI can complete on-chain queries and operations through natural language commands, such as “Query transactions for address 0x… in the last 7 days” or “Alert me when PEPE price exceeds $0.00001”.
Architecture
ChainStream adopts a three-layer architecture design, with each layer providing independent yet complementary capabilities:LAYER 3
AI Execution Layer
MCP Server · AI Tools · Natural Language API
LAYER 2
Security & Compliance
KYT · KYA · Audit · Risk Scoring
LAYER 1
Data Layer
Multi-chain Data · Real-time Stream · Smart Money
Each layer can be used independently or combined. For example, you can use only the Data layer to get price data, or combine Data + Security to implement deposit detection with risk control.
Why ChainStream
Built-in Compliance
Native KYT/KYA capabilities without third-party risk control services like Chainalysis. Reduce integration costs and data transmission risks.
AI-Native Design
MCP Server enables AI Agents to directly call on-chain capabilities. The first Web3 infrastructure designed for the AI era.
One-Stop Service
Data + Security + AI Execution unified API. One integration meets all data, risk control, and AI needs.
