Uniblock Raises $5.2M to Unify Blockchain Infrastructure

Blockchain infrastructure provider Uniblock has raised $5.2 million to operate a “managed infrastructure layer” across more than 300 blockchains, addressing a routing and failover problem that CEO Kevin Callahan said “should be solved once, not rebuilt by every team.”

The funding round, which brings total capital raised to $7.5 million, included participation from SBI, AllianceDAO, CoinSwitch, Blockchain Founders Fund, Hustle Fund, AAF Management, NGC Ventures, and strategic investors Alchemy and MoonPay, according to a company announcement shared with Decrypt.

The platform provides access to over 3,000 APIs through a single connection, with patented auto-routing handling provider selection, failover, and data normalization across 55 data partners.

Named customers running production workloads include Plume Network, Stellar Blockchain, Hypernative, Oku Trade, nReach, and Apechain, with Plume and Apechain operating Uniblock as their managed RPC infrastructure through ecosystem partnerships. The company reports 3,000 projects and 4,000 developers currently using the platform, which launched AI-native developer tools including an MCP server, LLM-optimized documentation, and agent skills for Cursor, GitHub Copilot and other AI coding environments.

“We’re watching two shifts happen at once. Fortune 500 companies are bringing production workloads to blockchain, and AI agents are starting to read and write chain data autonomously,” Callahan said in the announcement, which noted mainstream adoption signals including Stripe’s $1.1 billion acquisition of Bridge for stablecoins and prediction market odds appearing on legacy media broadcasts.

Uniblocks fundraise comes amid broader industry efforts to address multi-chain infrastructure challenges, with the Ethereum Foundation backing an “Economic Zone” initiative in February to solve fragmentation issues across the ecosystem’s growing number of Layer-2 networks.
