## What is the Optimism Sepolia Faucet?

Native ETH and USDT for the OP Stack

Optimism Sepolia is the official testnet for Optimism Mainnet and the broader Superchain ecosystem (Base, Mode, Zora, World Chain and other OP Stack networks). It settles to Ethereum Sepolia and uses the same bedrock client as production.

The Crypto Chief faucet drips native L2 ETH for gas and a test ERC-20 USDT for stablecoin scenarios — straight on the L2, no L1 bridging required.

Because OP Sepolia matches mainnet byte-for-byte, anything you build here transfers cleanly to Optimism, Base and the rest of the Superchain.

## How to claim OP Sepolia ETH & USDT

From sign-in to first drip in under a minute

1. Sign in to your Crypto Chief dashboard.
2. Open Faucet → **Optimism Sepolia**.
3. Paste the destination EVM wallet address.
4. Select ETH for gas or USDT for stablecoin tests.
5. Submit — tokens arrive in roughly two seconds.

## Got questions?  
we are here to help

## Is Optimism Sepolia the same as Goerli OP? 

No — Goerli OP was deprecated in 2024\. Optimism Sepolia (chain ID 11155420) is the current official testnet.

## Does this faucet drip on L1 or L2? 

Directly on the L2 — no need to bridge from Ethereum Sepolia.

## Can I reuse this for Base Sepolia? 

No, Base Sepolia is a separate network with its own chain ID. The faucet token amounts are similar, but you need to claim from the right network.

## Why does my L2 transaction take a few seconds longer? 

Optimism Sepolia targets \~2-second block times, but during network upgrades or chain reorganisations confirmation can briefly slow down. Drips are usually settled before the next refresh.

## What's the gas fee on OP Sepolia? 

Gas is virtually free in test ETH terms — typically less than 0.00001 ETH per transaction — so 0.05 ETH funds thousands of operations.
