QIE Blockchain
QIE Blockchain (QIE) is a Layer 1 using delegated proof of stake, with the QIE V3 architecture combining EVM compatibility and Cosmos-oriented infrastructure. Solidity contracts execute through an EVM environment against account-based state, while full nodes validate blocks and transactions and maintain balances, contract storage, validator information, and consensus state. This combination exposes familiar Ethereum contract semantics alongside Cosmos-style network components, so integrations can rely on EVM transaction conventions while also accounting for QIE-specific consensus.
QIE Blockchain API Methods and Endpoints
NOWNodes exposes QIE Blockchain's interface, plus a few others, depending on what your integration needs: JSON-RPC for reading chain state and broadcasting transactions. Archive mode extends any of these to historical states and data beyond standard retention.
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.
