Uniblock, a blockchain infrastructure provider, has secured $5.2 million in new funding to operate what it describes as a managed infrastructure layer across more than 300 blockchains. The raise brings the company’s total capital to $7.5 million. Chief Executive Kevin Callahan said the routing and failover problem the platform addresses is one that “should be solved once, not rebuilt by every team.”
The funding round drew participation from SBI, AllianceDAO, CoinSwitch, Blockchain Founders Fund, Hustle Fund, AAF Management, and NGC Ventures, alongside strategic investors Alchemy and MoonPay. The company shared details of the round in an announcement provided to Decrypt. The breadth of investors reflects growing institutional interest in multi-chain developer tooling.
Uniblock’s platform offers access to more than 3,000 APIs through a single connection. A patented auto-routing system manages provider selection, failover handling, and data normalization across 55 data partners. The design is intended to reduce the complexity developers face when building applications that span multiple blockchain networks.
Named customers running production workloads on the platform include Plume Network, Stellar Blockchain, Hypernative, Oku Trade, nReach, and Apechain. Both Plume and Apechain use Uniblock as their managed RPC infrastructure through ecosystem partnerships. The company reports that 3,000 projects and 4,000 developers are currently active on the platform.
Uniblock has also launched a set of AI-native developer tools, including an MCP server, documentation optimized for large language models, and agent skills compatible with Cursor, GitHub Copilot, and other AI coding environments. Callahan described two simultaneous industry shifts driving demand: Fortune 500 companies moving production workloads onto blockchain networks, and AI agents beginning to read and write chain data autonomously. The announcement cited mainstream adoption signals such as Stripe‘s $1.1 billion acquisition of Bridge for stablecoins and prediction market data appearing on legacy media broadcasts.
The raise arrives as the broader industry works to address fragmentation across multi-chain ecosystems. The Ethereum Foundation backed an initiative called the “Economic Zone” in February, aimed at resolving fragmentation issues across its growing number of Layer-2 networks. Uniblock’s approach positions it within this wider effort to simplify infrastructure management as the number of active blockchains continues to expand.
