What does Chainstream do?
Chainstream is a real-time on-chain data and execution platform built for Web3 AI agents, trading bots, and dApps. It gives developers a single API to stream decoded blockchain events, query token intelligence, track smart money movements, and execute transactions across multiple chains including EVM and Solana. The platform also includes built-in compliance tools like KYT (Know Your Transaction) and OFAC screening, so you can check addresses and transactions for risk without leaving your data pipeline.
What makes Chainstream different is how it connects AI agents to blockchain data. You can add on-chain capabilities to any agent with a single CLI command, or use its MCP server to let tools like Claude and Cursor call over 30 on-chain functions directly. The platform supports pre-consensus streaming — meaning you can see pending transactions before they're finalized — and auto-decodes raw hex into structured events like Swap, Mint, or Transfer without needing ABIs. For execution, Chainstream provides an agentic wallet, DEX routing, and a micropayment system where programs pay per API call in USDC.
Chainstream is most useful for developers building AI agents that need to interact with blockchain data in real time — whether that's a trading bot that snipes new token listings, a portfolio risk monitor that scans wallets, or a compliance tool that screens transactions before execution. The pricing is usage-based with a free tier (30K compute units per month) and paid plans starting at $199/month for heavier workloads.
