Can I Get zkSync Testnet Tokens?
Yes, you can get zkSync Sepolia testnet tokens from official faucets. First, connect your wallet (e.g. MetaMask) to the zkSync Sepolia testnet. Then, visit a compatible crypto faucet, enter your wallet address, and request test tokens.
These tokens are only for testing and allow developers to deploy zkSync smart contracts, interact with dApps, and experiment with zkChain deployments without using real ETH.
How to Get zkSync Testnet Tokens from a Faucet
Developers can obtain free zkSync Sepolia testnet ETH from trusted faucets, including QuickNode, a widely used provider for EVM-compatible networks. These tokens enable smart contract deployment, dApp testing, and zkChain experimentation on zkSync without using real funds.
Steps to Get zkSync Testnet Tokens:
- Connect Your Wallet: Open the QuickNode Faucet and connect an EVM wallet (e.g. MetaMask).

About zkSync
zkSync is a Layer 2 zk-rollup that scales Ethereum by executing transactions off-chain and verifying them on-chain with cryptographic validity proofs. It supports EVM-compatible smart contracts, compiled with zksolc and zkvyper, and features native account abstraction for flexible gas payments.
zkSync’s modular architecture enables developers to deploy custom zkChains using the ZK Stack, ensuring interoperability, shared liquidity, and Ethereum settlement for finality.
Final Thoughts
For developers testing zkSync smart contracts and dApps, accessing testnet ETH is straightforward through trusted faucets like QuickNode, Alchemy, and Chainstack.
Always verify faucet sources to avoid scams, and ensure your wallet is correctly set to zkSync Sepolia before requesting funds.
