ChainStream’s On-Chain Data API is your gateway to actionable token, pool, contract, and address data across major networks. Whether you’re building a DEX, wallet, risk engine, or analytics platform, this API gives you the foundational layer needed to power intelligent decisions and in-app insights.

​
Why Use ChainStream On-Chain Data?

Blockchain data is powerful, but it’s messy. Developers are often left parsing raw logs or writing custom indexers just to answer simple questions—What is this token’s price? Is this address suspicious? Does this pool have liquidity?

ChainStream solves this with a clean, query-ready interface to the core objects that define on-chain behavior. You get structured data, optimized for performance and clarity, without needing to decode contracts or chase chain-specific formats.

​
What You Can Query

Token Data

Get detailed token-level insights, including metadata, real-time price, liquidity, trading volume, and market activity over the past 24 hours.

DEX Pair & Pool Info

Discover active liquidity pools and trading pairs across multiple chains. Surface top pairs, track real swap activity, and assess pool-level TVL, token composition, and price impact data.

Address Intelligence

Enrich user and contract addresses with behavioral tags. Identify centralized exchanges, smart contracts, MEV bots, attackers, or newly created wallets to build safer user flows and security triggers.

Smart Contract Metadata

Retrieve source info, verification status, and relationships between contracts and token ownership. Useful for contract monitoring, token discovery, and audit tooling.

Cross-Chain Pool Lookup

Access pool-level data across EVM chains and Solana. Filter by token, liquidity depth, or protocol to monitor the current state of DEX liquidity globally.

​
Common Use Cases

Wallet Applications

Display token price, liquidity profile, and risk labels directly in asset views.

DEX & Aggregator Platforms

Query active pools and pairs to surface the best routes and minimize slippage.

On-Chain Risk Engines

Flag suspicious addresses or low-liquidity tokens before a transaction is signed.

Analytics Dashboards

Power dashboards with up-to-date token and DEX activity, address classification, and protocol stats.
