Cambrian raises $6 million seed round to build blockchain data oracle network

Cambrian, a U.S.-based startup building blockchain data infrastructure for institutions and AI agents, has raised $6 million in a seed round co-led by Franklin Templeton and Polychain Capital. The financing brings Cambrian’s total funding to $11.9 million, following a $5.9 million pre-seed round led by a16z Crypto Startup Accelerator (CSX) last year. Founder and CEO Sam Green said the round was structured as a SAFE (simple agreement for future equity) with token warrants, and that Franklin Templeton and Polychain took board observer seats. Founded in 2024, Cambrian provides an API for real-time and historical blockchain data, including yield, risk, lending rates, trading activity, liquidity positions, and market sentiment. The company plans to extend that product into a verifiable oracle network, aimed at institutions and AI agents that need dependable data to allocate capital onchain. Unlike many crypto oracle networks that focus mainly on price feeds, Cambrian says it combines lending protocol data, decentralized exchange liquidity, social sentiment, developer activity, and historical market information on one platform. Green said the platform is still in private beta, with TrueNorth using it in production as a design partner for trading data. Cambrian currently supports Base and Solana in production and plans to add Ethereum mainnet next, followed by several more blockchains. The company said the alpha version of its oracle network has already been completed in collaboration with researchers from a16z crypto, with integrations with blockchain and decentralized finance partners expected in the coming months. Cambrian plans to use the new capital to broaden blockchain and protocol coverage and accelerate oracle network development.
