Uniblock

Uniblock is a Web3 infrastructure platform that provides a standardized API aggregating data from hundreds of DEXs and cross-chain bridges, abstracting the complexity of multi-chain development into a single endpoint. The platform completed $5.2 million in financing with $7.5 million in total funding.

Uniblock publishes 7 APIs on the APIs.io network, including JSON-RPC API, Direct Pass-Through API, Market Data API, and 4 more. Tagged areas include Blockchain and Web3.

The Uniblock catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 3 Spectral governance rulesets.

Uniblock’s developer surface includes authentication, developer portal, documentation, getting-started guide, engineering blog, and 15 more developer resources.

  description: The Uniblock JSON-RPC API provides a single endpoint for standard JSON-RPC calls across hundreds of blockchain
    networks. Rather than managing individual node provider connections for each chain, developers can send JSON-RPC requests
    through Uniblock which automatically selects the best upstream node provider. This supports standard Ethereum and EVM-compatible
    JSON-RPC methods, as well as Solana and other chain-specific RPC interfaces, with built-in failover and automatic retries.
