Cambrian raises $6M for blockchain oracle

Highlights

Cambrian closes $6 million seed round co-led by Franklin Templeton and Polychain Capital, raising total funding to $11.9 million as of last month.
Cambrian expands blockchain data API into a verifiable oracle network targeting institutional finance and AI agents seeking onchain capital allocation data.
The platform indexes $4.5 billion in lending TVL, monitors 1,789 vaults and 320,000+ DEX pools, and aims to monetize via SaaS, enterprise contracts, and agent payments.

Seed financing and expansion plans

As reported by The Block, Cambrian says Franklin Templeton and Polychain Capital co-lead its $6 million seed round, with participation from Flow Traders, Selini Capital, Paper Ventures, Nomad Capital and other investors. Angel investors including Jason Mo, Avi Felman, and TrueNorth co-founders Alex Lee and Willy Chuang also join the financing.

Founder and CEO Sam Green says Cambrian begins fundraising toward the end of last year and formally closes the round last month. He says the financing is structured as a SAFE with token warrants, while Franklin Templeton and Polychain take board observer seats; Green declines to disclose the valuation.

The seed financing brings Cambrian's total funding to $11.9 million, including a $5.9 million pre-seed round led by a16z Crypto Startup Accelerator, or CSX, last year.

Institutional and AI demand shapes product strategy

Founded in 2024, Cambrian offers an API for real-time and historical blockchain data spanning 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.

Green says Cambrian is built to support both centralized and verifiable network modes, which he says helps it serve institutional finance customers as well as agent builders and protocols that require verifiable data. The company says its platform goes beyond standard crypto price feeds by aggregating lending protocol data, decentralized exchange liquidity, social sentiment, developer activity and historical market data in one system.

Cambrian says it has processed millions of API calls, indexes $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. The startup plans to generate revenue through SaaS subscriptions, enterprise contracts and support for agent-based payment systems such as x402, and Green says the 10-person U.S. team plans to hire a blockchain infrastructure engineer and a sales lead.

We noted the focus on modernizing and harmonizing oversight frameworks to keep pace with rapid technological change while protecting resilience, governance and financial stability.
