Starknet Testnets

Starknet Sepolia is the primary testnet environment for Starknet, built to closely replicate the behavior of the Starknet Mainnet. It is connected to the Ethereum Sepolia testnet, enabling developers to test cross-layer interactions and smart contracts in a realistic, low-risk setting.

This environment is ideal for:

• Debugging and refining Cairo-based smart contracts

• Testing dApp functionality under near-mainnet conditions

• Validating Ethereum–Starknet interactions using Sepolia ETH

Starknet Sepolia offers developers a reliable staging ground before deploying to Mainnet.
