# Neo N3 Real-World Reference Data

This file provides essential reference data for working with Neo N3 mainnet and testnet, including contract addresses, RPC endpoints, and NeoFS endpoints.

## Native Contract Addresses

Native contracts are the built-in contracts that provide core functionality to the Neo N3 blockchain. These addresses are consistent across both mainnet and testnet:
