Uniblock raises $5.2M to simplify multi-chain blockchain development
Uniblock closed a $5.2M round as investors bet on tools that help developers work across hundreds of blockchains without the usual infrastructure headaches.
UniblockTL;DR:
- Uniblock raised $5.2M from backers across Asia, the US, and Europe to build out its multi-chain API platform.
- Investors are betting on middleware that makes blockchain development less painful for enterprises and AI applications.
- The company is leaning into AI tooling—MCP servers, documentation built for LLMs, agent integrations—as a way to stand out.
- Next up: more chain support, better orchestration, and new APIs for stablecoins, wallets, and prediction markets.
- Customers report meaningful cost savings by consolidating their blockchain infrastructure onto a single platform.
A Single API for 300+ Blockchains
Uniblock, a Toronto-based Web3 infrastructure company, announced a $5.2 million funding round on March 31, 2026. The company built a managed layer that connects applications to over 300 blockchains and 55 data providers through one interface, handling the messy work of routing, failover, and data normalization.
CEO Kevin Callahan previously worked at Coinbase and Twitter. He founded the company with CTO David Liu and VP of Engineering James Liu. The platform now supports more than 3,000 projects, including Plume Network, Stellar Blockchain, and Apechain, with about 4,000 developers using tools like intelligent routing and AI integrations.
This round brings total funding to $7.5 million, following a $2.3 million pre-seed in November 2023 from Blockchain Founders Fund, Cadenza, Side Door Ventures, and others. The new round drew a geographically diverse group of investors.

The funding comes alongside new AI developer tools: an MCP server for agents to query blockchain data directly, documentation formatted for LLMs, and integrations with coding environments like Claude and Cursor. The pitch is that AI agents need to transact across multiple chains, and no single provider covers everything reliably. Oku Trade says it cut costs by 30% after moving its RPC traffic to the platform.
What Investors Are Betting On
Backers pointed to the fragmentation problem as the main draw. Developers often spend months just managing RPC providers and integrations across different chains. Uniblock gives them one API key for over 3,000 APIs.
The money will go toward adding more chains, scaling the orchestration engine, and building APIs for stablecoins, wallets, and prediction markets. The company is also investing in AI tooling and enterprise features.
- SBI Digital Asset Holdings and AllianceDAO anchor the round, connecting Uniblock to Japan and the Solana ecosystem.
- Alchemy and MoonPay's participation points to interest in developer tools and payments.
- Blockchain Founders Fund invested again after the pre-seed.
- NGC Ventures and Hustle Fund add reach across Asia, India, and early-stage networks.
- The investor mix suggests broad confidence that multi-chain tooling has legs.
Recent moves include a public MCP endpoint that works without an API key, letting AI agents pull token balances, transaction history, NFTs, and market data. Partnerships with Stellar and Apechain for managed RPC services show the platform gaining traction with established projects.
The timing matters. Blockchain adoption is picking up with tokenized assets hitting regulated exchanges and AI agents starting to interact with on-chain data. Infrastructure that actually works across chains becomes more valuable as applications outgrow single-chain setups.
Bottom line: Investors keep funding tools that make multi-chain development less of a nightmare.
