Starknet RPC
Starknet Overview
Starknet is a Layer 2 zero-knowledge rollup (zkRollup) built on Ethereum. It uses zk-STARKs to generate and verify proofs, enabling efficient transaction settlement on Ethereum with lower gas costs compared to zk-SNARKs.
Starknet runs on CairoVM, a custom virtual machine, and uses the Cairo programming language for smart contracts. Cairo is designed to produce proofs efficiently while offering developers a Solidity-like experience with stronger security guarantees, influenced by Rust.
Transactions on Starknet can be paid in STRK (its native token), ETH, or USDC.
Interacting with Starknet’s APIs
Starknet exposes a JSON-RPC interface that enables programmatic access to incoming block and transaction data. Use this interface to read chain state, submit transactions, and interact with contracts. The QuickNode Starknet documentation is continuously evolving as the chain undergoes upgrades and changes, so we highly recommend cross-referencing with the official Starknet documentation for the latest updates on its RPC methods.
Make Starknet API Calls
The quickest way to start building on Starknet is to create a QuickNode endpoint and send your first JSON-RPC request.
QuickNode provides managed Starknet endpoints, giving you immediate access to the Starknet Mainnet and Sepolia Testnet without the overhead of running infrastructure. These endpoints offer:
- High reliability – globally distributed infrastructure designed to minimize downtime
- Archive data – full historical state for in-depth queries
- Enhanced performance – optimized latency and request handling for production-grade apps
- Integrated ecosystem – additional functionality through specialized APIs (add-ons) on the QuickNode Marketplace
Visit the QuickStart page to create your endpoint and send your first request.
