Test tokens for the leading Ethereum rollup Arbitrum Sepolia is the official testnet for Arbitrum One — the largest optimistic rollup on Ethereum. It settles to the Ethereum Sepolia network and uses the same Nitro tech stack as mainnet, which makes it the gold standard for testing rollup-aware dApps. The Crypto Chief Arbitrum Sepolia faucet drips both native L2 ETH and a test ERC-20 USDT. Both tokens live entirely on the L2 — no bridging required to start building. If your app interacts with the Arbitrum bridge, you can combine this faucet with the Ethereum Sepolia faucet to fund both layers in a single workflow. ## How to get Arbitrum Sepolia ETH & USDT From sign-in to first drip in under a minute 1. Sign in to your Crypto Chief dashboard or create a free account. 2. Open the Faucet page and choose **Arbitrum Sepolia**. 3. Enter the destination EVM wallet address. 4. Select ETH for L2 gas or USDT for stablecoin testing. 5. Submit — most drips land within a single Arbitrum block (sub-second). ## Examples of Use What developers build with free Arbitrum Sepolia tokens #### Rollup-native dApps Test contracts on a real optimistic rollup with realistic gas economics before deploying to Arbitrum One. #### Bridging flows Combine with Ethereum Sepolia to debug deposits, withdrawals and message passing across L1 and L2. #### Gas optimization Profile call data size and L1 batch costs — the biggest contributors to L2 fees — using realistic testnet conditions. #### Stablecoin integrations Wire up payments, swaps, perps and lending markets with a test USDT that mimics the mainnet interface. #### On-chain gaming Validate high-throughput interactions and meta-transactions where L2 fees actually matter. #### Pre-mainnet audits Replay incident scenarios and security tests in an environment that matches Arbitrum One byte-for-byte. ## Got questions? we are here to help ## Is the Arbitrum Sepolia faucet free? Yes — Arbitrum Sepolia ETH and test USDT have no monetary value and are free for any signed-in Crypto Chief user. ## How fast does the faucet send tokens? Arbitrum Sepolia has sub-second block times, so most drips appear in the destination wallet within 1–2 seconds. ## Do I need Ethereum Sepolia ETH first? No. Our faucet drips ETH directly on the L2, so you can start using Arbitrum Sepolia without bridging from L1. ## Can I bridge faucet USDT to other chains? No — the test USDT lives only on Arbitrum Sepolia. To test bridging you need to use the production bridge contracts with separate faucet balances on each side. ## Is this the same network as Arbitrum Nova testnet? No. Arbitrum Sepolia is the testnet for Arbitrum One. Arbitrum Nova has a separate, less commonly used testnet. ## Pricing that grows with your needs. ### Free Start building on Web3 — no credit card. ##### $0 - 5 reqs/sec RPC - 5 reqs/min Unified API - 1 req/day AML - Ultimate chains - WSS, Statistics - Community support [Get started ](https://auth.crypto-chief.com/registration) ### Pay for use Flexible pay-as-you-go for any workload. ##### From $10 - 400 reqs/sec RPC - 300 reqs/min Unified API - 5 reqs/sec AML - EventStream - Ultimate chains - WSS, Whitelists, Statistics - Support portal [Get started](https://auth.crypto-chief.com/registration) ### Subscription From $500 monthly plus 20% extra value. ##### From $500 - 400 reqs/sec RPC - 300 reqs/min Unified API - 5 reqs/sec AML - EventStream - Ultimate chains - WSS, Whitelists, Statistics - Support portal [Get started ](https://auth.crypto-chief.com/registration) ### Enterprise Tailored solution for expert builders ##### Custom terms All Subscription features plus: - Flexible rate limits - Engineering team support - Custom SLA - Personal manager [Contact Sales ](/contact/) #### Fund your Arbitrum Sepolia wallet in a single click [Claim ETH & USDT](https://auth.crypto-chief.com/registration)
