Cambrian Raises $6M to Build Verifiable Blockchain Oracle

Cambrian, a U.S.-based startup founded in 2024, closed a $6 million seed round last month co-led by Franklin Templeton and Polychain Capital. The seed brings the company's total funding to $11.9 million after a $5.9 million pre-seed led by a16z's Crypto Startup Accelerator in 2025. Sam Green is the company's chief executive.

The startup currently provides an API that delivers real-time and historical blockchain data on yield, risk, lending rates, trading activity, liquidity positions and market sentiment. The firm plans to extend that API into a verifiable oracle network aimed at institutional finance teams and autonomous AI agents that require auditable data to move and allocate capital onchain.

The seed was structured as a simple agreement for future equity with token warrants. Franklin Templeton and Polychain took board observer seats. Other investors included Flow Traders, Selini Capital, Paper Ventures, Nomad Capital and angel backers Jason Mo, Avi Felman, Alex Lee and Willy Chuang. Green declined to disclose a valuation.

Cambrian aggregates lending protocol metrics, decentralized exchange liquidity, social sentiment, developer activity and historical market data into a single feed. The company reports it has processed millions of API calls, indexes about $4.5 billion in lending total value locked across the four largest lending protocols, tracks 1,789 vaults across 895 curators and monitors more than 320,000 decentralized exchange pools across Base and Solana.

Production support currently covers Base and Solana. The team plans to add Ethereum mainnet next and to expand support for other blockchains. Cambrian is preparing expanded trading coverage, including integrations for Hyperliquid and broader perpetuals data.

An alpha version of the verifiable oracle network is complete, developed with input from researchers at a16z crypto, and Cambrian plans integrations with blockchain and decentralized finance partners in the coming months. TrueNorth, an agentic brokerage, has been a close design partner and uses Cambrian's data in production.

The company intends to generate revenue through software-as-a-service subscriptions, enterprise contracts and support for agent-based payment systems such as x402. Cambrian employs 10 people and is hiring a blockchain infrastructure engineer and a sales lead.

Several members of Cambrian's team previously worked at Edge & Node or Semiotic Labs, teams connected to The Graph indexing network.

“We are the only data provider designed from the outset to support both centralized and verifiable network modes,” Sam Green, CEO, stated.
