Injective
Injective (INJ) is a Cosmos SDK Layer 1 secured by proof-of-stake validators, with its MultiVM architecture supporting native modules, CosmWasm, and EVM execution on one shared state machine. CosmWasm contracts commonly compile from Rust and EVM applications use Solidity, while full nodes execute transactions across modules and virtual machines and maintain account, market, staking, and contract state. This combination connects Cosmos transaction conventions with Ethereum-compatible execution, so integrations can span both native Injective and EVM-facing interfaces.
Injective API Methods and Endpoints
NOWNodes exposes Injective's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions, and WSS (WebSocket) for real-time subscriptions and events.
Browse the interfaces below for endpoint details, request parameters, response formats, and integration examples. Create an API key, select Mainnet or Testnet, choose the required interface, and start sending requests from your application.
