Injective RPC
What is Injective?
Injective is a Layer 1 blockchain built for decentralized finance (DeFi). It provides core financial features like exchanges, derivatives, lending, staking, and oracles directly on-chain, so developers don’t need to build everything from scratch with complex smart contracts. Injective is built with the Cosmos SDK, giving it fast transaction finality and interoperability with other blockchains in the Cosmos ecosystem. It also offers a smooth, gas-free user experience, a built-in decentralized order book, support for smart contracts through CosmWasm, and tools for creating specialized blockchains tailored to unique applications.
Interacting With Injective’s APIs
Injective endpoints expose several interfaces, including Cosmos REST and gRPC, Tendermint RPC, and an Ethereum-compatible JSON-RPC API. The JSON-RPC interface enables developers to use Ethereum tools such as Foundry, Hardhat, and popular Web3 libraries without modification.
Quicknode also provides the Injective Indexer gRPC API, which offers indexed blockchain data and transaction utilities through Explorer and Exchange services. Use it to query blocks, transactions, validators, contracts, bridge activity, and statistics, stream blocks and transactions, or prepare and broadcast transactions.
However, due to Injective’s architectural differences, some RPC methods may behave differently from those on Ethereum. The Quicknode Injective documentation is continuously evolving as the chain undergoes upgrades and changes, so we highly recommend cross-referencing with the official Injective documentation for the latest updates and RPC differences.
Make Injective API Calls
The quickest way to start building on Injective is to create a Quicknode endpoint and send your first request.
Quicknode provides managed Injective endpoints, offering:
- High reliability — globally distributed infrastructure designed to minimize downtime
- Enhanced performance — optimized latency and request handling for production-grade apps
Visit the QuickStart page to create your endpoint and send your first request.
Supported Networks
Quicknode provides access to multiple Injective networks.
Injective endpoints on Quicknode do not currently offer archive data. Nodes are configured with pruning, retaining approximately the most recent 1,832,727 blocks of state history. Queries for blocks or state outside the retained range will return an error.
To query data within the available range, use the x-cosmos-block-height header with REST API requests or specify the height parameter with Tendermint API requests. Ensure the block height used is within the recent pruning window.
Cosmos REST API Example:
curl --location 'https://docs-demo.injective-mainnet.quiknode.pro/cosmos/distribution/v1beta1/delegators/inj1jclptl8mx6vtc4l6mjv5smwdpxmc2pp3kelmjr/rewards' \
--header 'x-cosmos-block-height: 113823949'
Tendermint API Example:
curl --location 'https://docs-demo.injective-mainnet.quiknode.pro/block?height=113823949'
