Uniblock has closed a $5.2 million funding round to scale a managed infrastructure layer that connects applications to more than 300 blockchains, aiming to solve the repeated headaches of routing, provider selection and failover that teams currently rebuild project-by-project.
The raise — which brings Uniblock’s total capital to $7.5 million — included participation from SBI, AllianceDAO, CoinSwitch, Blockchain Founders Fund, Hustle Fund, AAF Management, NGC Ventures, and strategic backers Alchemy and MoonPay, the company said in an announcement shared with Decrypt.
Uniblock offers a single connection to more than 3,000 APIs and uses patented auto-routing to pick providers, handle failover and normalize data across 55 data partners. The platform is already running production workloads for customers including Plume Network, Stellar Blockchain, Hypernative, Oku Trade, nReach and Apechain — with Plume and Apechain using Uniblock as their managed RPC infrastructure via ecosystem partnerships.
The company reports 3,000 projects and 4,000 developers on the platform. It has also launched AI-native developer tools: an MCP server, LLM-optimized documentation, and agent skills that integrate with AI coding environments such as Cursor and GitHub Copilot, positioning its stack for applications where AI agents read and write on-chain data.
“We think this routing and failover problem should be solved once, not rebuilt by every team,” CEO Kevin Callahan said. He added that Uniblock is timing product development to two converging shifts: Fortune 500 companies putting production workloads on-chain, and AI agents autonomously interacting with blockchain data.
Uniblock’s fundraise comes as the broader ecosystem tackles multi-chain fragmentation. In February the Ethereum Foundation backed an “Economic Zone” initiative to address fragmentation across the growing number of Layer-2 networks — a sign that multi-chain infrastructure is becoming a central industry focus.
