If you are developing smart contracts, testing decentralized applications, or farming airdrops on Arbitrum’s Layer 2 ecosystem, you need Arbitrum Sepolia ETH to cover your transaction gas fees.

Method 2: Get Ethereum Sepolia & Bridge to Arbitrum Sepolia
If direct L2 faucets are congested or temporarily empty, the most bulletproof pro-method is getting standard Ethereum Sepolia ETH and bridging it directly to Arbitrum.
Step 1: Claim Ethereum Sepolia ETH
First, grab your base testnet tokens using a reliable source like the Alchemy Sepolia Faucet (alchemy.com/faucets/ethereum-sepolia).
Step 2: Use the Official Arbitrum Bridge
1. Go to the official Arbitrum Bridge Portal (https://bridge.arbitrum.io/).
2. Connect your Web3 wallet and set the source network to Ethereum Sepolia and destination to Arbitrum Sepolia.
3. Enter the amount of Sepolia ETH you wish to transfer and click Move funds to Arbitrum Sepolia.
4. Confirm the transaction in your wallet. The tokens will reflect in your Arbitrum Sepolia address shortly.
Pro-Tips for Airdrop Hunters
– Keep Extra Gas: Always leave a small amount of Arb-Sepolia ETH unspent so your subsequent testnet transactions don’t fail due to insufficient gas.
– Stay Safe: Never interact with random links promising “paid” testnet tokens. Arbitrum testnet funds are always 100% free.
