Pathfinder
Pathfinder is a Starknet full node implementation in Rust - built by a team from Equilibrium Labs. Pathfinder allows users to run a node and query their own data, rather than trusting information provided by others.
Go to GitHub, run the node, and query your own data.
Pathfinder gives you access to the full Starknet state history, including contract code, storage, and transactions. Pathfinder calculates the Starknet state's Patricia-Merkle Trie root on a block-by-block basis and confirms it against L1. This means the contract code and storage are locally verified.
You can call StarkNet contract functions against the local state using the Ethereum-like RPC API. This avoids incurring the cost of a StarkNet transaction as the call is performed locally only.
Pathfinder is authored and maintained by the team at Equilibrium Labs.
