What is Sepolia ETH used for?

Use Ethereum Sepolia for deploying and testing smart contracts and dapps. Ethereum Sepolia ETH is distinct from Base Sepolia, OP Sepolia, and Arbitrum Sepolia ETH; this service delivers only to Ethereum Sepolia.

How to buy Sepolia ETH

  1. Choose a whole-number amount between 1 and 100 and an EVM recipient address on the quote form.

  2. Review the free quote and copy the purchase URL. Send that URL through an x402 client supporting Base or Solana mainnet USDC. Solana payments require an explicit EVM recipient.

  3. After payment settlement, use the order status URL returned by the API to follow the queued payout. The eventual testnet transaction can be checked on the network explorer.

Delivery depends on service availability, available inventory, and network processing. A quote is not a reservation or a completed purchase.

Free faucets or paid delivery?

If a small free allocation meets your needs, start with a public faucet. This service charges for automated delivery from privately controlled inventory and payment handling, with a requested amount and an order status API.

Testnet ETH has no monetary value and is not mainnet ETH. The USDC payment is real mainnet money for the delivery service.

See Ethereum’s network documentation for testnet context and resources.

Before you order

Can I buy a fraction of one ETH?

No. Orders use whole numbers within the 1–100 ETH range.

Can I pay with testnet USDC?

No. Payment uses mainnet USDC on a supported Base or Solana x402 payment rail.

Where will my tokens be sent?

To the specified EVM address on Ethereum Sepolia. For Base payments, the verified payer address is used if no recipient is supplied.

How do I track the delivery?

Use the order status URL in the purchase response. It reports the payout status and the testnet transaction when available.
