Uniblock, a managed infrastructure layer for blockchain applications, announced it has raised $5.2 million in new funding, bringing its total funding to $7.5 million. The round included a global group of investors spanning the U.S., Japan, India, Singapore, and the Solana ecosystem, along with participation from executives affiliated with major crypto and technology companies.
The company is focused on solving a growing challenge in blockchain development, fragmentation across data providers and networks. As blockchain adoption expands and artificial intelligence agents increasingly interact with onchain data, developers face complexity in accessing reliable infrastructure across multiple chains.
Uniblock addresses this by offering a unified API layer that connects applications to more than 300 blockchains and over 3,000 APIs through a single integration. Its platform includes automated routing, failover systems, and data normalization, reducing the need for developers to build their own infrastructure orchestration.
The company reports that more than 3,000 projects and 4,000 developers are already using its platform in production. Customers include blockchain networks and applications that rely on consistent, multi-chain data access.
Alongside the funding, Uniblock introduced a suite of AI-native developer tools designed to align with modern development workflows. These include tools that allow AI agents to directly interact with blockchain APIs, structured documentation optimized for large language models, and pre-built integration prompts for AI coding environments.
The company plans to use the new capital to expand its platform capabilities, increase blockchain coverage, enhance its orchestration engine, and develop new API categories such as stablecoins, wallets, and prediction markets. It will also continue investing in AI tooling and scaling its engineering and operations teams.
Uniblock is headquartered in Canada and positions itself as a foundational infrastructure provider for both traditional enterprises entering blockchain and AI-driven applications requiring reliable, multi-chain access.
KEY QUOTES:
“Two shifts are happening at once. Mainstream companies are bringing production workloads to blockchain, and AI agents are starting to read and write chain data autonomously. Both need the same thing: reliable infrastructure across hundreds of chains. That’s what Uniblock runs.”
Kevin Callahan, CEO And Co-Founder, Uniblock
“The next wave of blockchain adoption will depend on infrastructure that simplifies an increasingly complex ecosystem while maintaining dependable performance. Uniblock is building exactly that through a single API layer that simplifies multi-chain access for developers, enterprises, and AI-driven applications, and we are pleased to support the team as it enters this next phase of growth.”
Eiichiro So, CEO And Managing Director, SBI Ven Capital
“Stripe bought Bridge for $1.1B. Visa is embracing onchain. AI agents are transacting autonomously. All of them need reliable multi-chain infrastructure. Uniblock built it. 3,000 projects already run on the platform and that number only grows from here.”
Aly Madhavji, Managing Partner, Blockchain Founders Fund
