Welcome to Pathfinder

Pathfinder is a Rust implementation of a Starknet full node that provides a secure view into the Starknet blockchain. As a full node, Pathfinder provides access to Starknet's entire state history, allowing users to query contract code, storage, and transactions.

Key features​

  • Full Starknet State Access: Retrieve the full history, including contracts, transactions, and storage.
  • Verification via Ethereum: Verifies the state of Starknet using Ethereum, calculating Patricia-Merkle Trie roots to ensure the correctness of data.
  • JSON-RPC Support: Implements the Starknet JSON-RPC API, providing full support for interacting with the blockchain through tools like starknet.js and starknet.py.
  • State Functionality without Transactions: Execute Starknet functions locally without requiring an actual transaction on the network.
  • Transaction Fee Estimation: Estimate the gas fees for a transaction before submitting it to the network.
