Cambrian, a startup building blockchain data infrastructure for institutions and AI agents, has raised $6 million in a seed funding round.

Franklin Templeton and Polychain Capital co-led the round, with participation from Flow Traders, Selini Capital, Paper Ventures, Nomad Capital, and others, Cambrian said Wednesday. Angel investors, including Jason Mo, Avi Felman, and TrueNorth co-founders Alex Lee and Willy Chuang, also joined the round.

Cambrian began fundraising toward the end of last year and formally closed the round last month, founder and CEO Sam Green told The Block. The round was structured as a simple agreement for future equity (SAFE) with token warrants, Green said, declining to disclose valuation. Franklin Templeton and Polychain took board observer seats as part of the round, Green said.

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

Building a blockchain data oracle network

Founded in 2024, Cambrian currently offers an API that provides real-time and historical blockchain data covering yield, risk, lending rates, trading activity, liquidity positions, and market sentiment. The startup plans to expand that offering into a "verifiable" oracle network designed for institutions and AI agents that need reliable data to allocate capital onchain.

"We are the only data provider designed from the outset to support both centralized and verifiable network modes," Green claimed. "This enables us to serve institutional finance customers who are early adopters of crypto and DeFi, as well as agent builders and protocols that require verifiability to safely control capital within their products."

Unlike traditional crypto oracle networks that primarily provide price feeds, Cambrian said it aggregates lending protocol data, decentralized exchange liquidity, social sentiment, developer activity, and historical market data into a single platform. The platform said it has already processed millions of API calls, currently 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.

"We cover a broad range of financial data, both onchain and offchain, and are preparing to expand our trading support by adding Hyperliquid and extensive perp data," Green said.

When asked how institutions specifically use the platform, Green said an institution or AI agent seeking yield opportunities, for instance, can use Cambrian's API to compare lending markets and supply rates across protocols and blockchains. The platform also tracks social media sentiment around onchain assets and analyzes how that sentiment correlates with subsequent price movements.

"We are still in private beta," Green said. "TrueNorth, an agentic brokerage, has been our closest design partner for trading data, and they use us in production. We are actively engaging leading institutional asset managers on several product designs and have an extensive list of agentic projects on the waitlist for our API."

Cambrian currently supports Base and Solana in production. Green said the Ethereum mainnet will be added next, with several additional blockchains expected to follow. Cambrian plans to use the new funding to expand blockchain and protocol coverage and speed up development of its oracle network.

Green said the alpha version of Cambrian's oracle network has already been completed and was designed in collaboration with researchers from a16z crypto. Cambrian plans to begin integrations with blockchain and decentralized finance partners in the coming months.

As for its business model, Cambrian plans to generate revenue through software-as-a-service (SaaS) subscriptions, enterprise contracts, and supporting agent-based payment systems such as x402, according to Green.

U.S.-based Cambrian currently employs 10 people and plans to hire a blockchain infrastructure engineer and a sales lead, Green said. Notably, Cambrian's team members previously worked at Edge & Node, which founded blockchain data indexing network The Graph, or at Semiotic Labs, a core development team for The Graph.
