Toronto-based blockchain infrastructure startup Uniblock has successfully closed a $5.2 million seed funding round, bringing its total capital raised to approximately $7.5 million since its founding. The oversubscribed round attracted a global consortium of investors from the United States, Japan, India, Singapore, and the Solana ecosystem.
Key investors in the round include SBI, AllianceDAO, CoinSwitch, Blockchain Founders Fund, Hustle Fund, AAF Management, and NGC Ventures. Strategic investments also came from major industry players Alchemy and MoonPay. The round was further bolstered by angel investors with backgrounds at prominent companies like Kraken, Uber, and CoinList.
Uniblock's core value proposition addresses a critical fragmentation issue in multichain development. No single blockchain data provider covers every network an application may need or guarantees constant availability. To solve this, Uniblock operates a managed infrastructure layer that sits between applications and over 55 underlying data providers. Its platform offers developers access to more than 300 blockchains and over 3,000 APIs through a single integration key.
The company's patented automatic routing technology handles provider selection, failover, and data normalization automatically, eliminating the need for each development team to build and maintain its own complex routing systems. The platform currently supports more than 3,000 active projects and 4,000 developers. Notable production clients relying on Uniblock for managed RPC infrastructure include Plume Network, Stellar Blockchain, Hypernative, Oku Trade, and Apechain.
Concurrent with the funding announcement, Uniblock launched a suite of AI-native developer tools. This includes an MCP (Model Context Protocol) server that allows AI agents to call unified APIs directly, structured documentation in an `llms.txt` format optimized for language models, and ready-to-use context snippets for environments like Claude, Cursor, and GitHub Copilot.
"Two shifts are happening at the same time. Traditional enterprises are bringing productive workloads onto blockchain, and AI agents are beginning to read and write on-chain data autonomously," said Kevin Callahan, CEO and co-founder of Uniblock. The newly raised capital will be used to expand chain coverage, scale the intelligent orchestration engine, and incorporate new API categories, including stablecoins, wallets, and prediction markets.
