Barzakh is positioned as an AI-first tool for automating blockchain data workflows. It analyzes on-chain activity and helps users move seamlessly from insight to action.
Barzakh is a next-generation AI-powered blockchain intelligence and automation platform engineered to redefine how blockchain data is processed, understood, and acted upon via programmatic payments. By seamlessly blending real-time, verifiable on-chain data with context-aware AI agents and x402-powered settlement rails, Barzakh eliminates the manual friction between insight discovery and on-chain execution, allowing users to operate at the speed of blockchain itself.
Barzakh's architecture is designed for multi-chain dominance — aggregating intelligence from EVM-compatible networks (including Ethereum Mainnet, Cronos EVM, Cronos zkEVM, Mantle, Polygon, Arbitrum, Optimism, Base, and other Layer-2s) alongside non-EVM ecosystems like Sei Native, Aptos, Flow, Wormhole, Zeta, and more. Deep integration with the Crypto.com ecosystem — including the Crypto.com AI Agent SDK and Market Data MCP Server — positions Barzakh as a universal blockchain intelligence layer with native AI-to-commerce capabilities.
In a blockchain landscape where speed, accuracy, and actionable intelligence determine competitive edge, Barzakh's mission is clear:
Deliver instant, AI-curated intelligence across multiple blockchain networks
Integrate on-chain and off-chain data into a single coherent view
Enable AI agents to autonomously trigger x402 gasless payments based on market conditions, user intent, or automated workflows
Empower developers, traders, enterprises, and protocols to automate decision-making without sacrificing accuracy or context
Where other platforms stop at analytics, Barzakh executes — turning market shifts, wallet behaviors, and sentiment changes into triggered, automated actions settled on-chain via x402 protocol.
