Buy Claude Pro with Ethereum

Which ETH network to use

Network choice decides most of what you pay in fees, and getting it wrong is the one mistake that loses funds outright. Match the network shown on the private payment page exactly.

The case for paying with ETH

• Gas is no longer the objection it was — a mainnet ETH transfer in normal conditions costs cents rather than the double-digit dollars people remember from 2021.
• The most widely held asset after Bitcoin, so many buyers already have ETH and would rather spend it than sell it first.
• Every exchange, wallet and on-ramp supports it, so acquiring it is never the hard part.
• Settlement is quick enough at subscription size that price drift during confirmation is rarely material.

The case against

• The address format is identical across Ethereum mainnet and every EVM layer 2, so the one visual check that catches most wrong-network errors — TRON addresses start with T, Ethereum with 0x — does nothing for you here.
• Volatile. On a fixed-price purchase you are carrying price risk for no benefit, and a stablecoin gives you the same rails without it.
• Gas is variable rather than fixed. It is cheap most of the time and it is not always cheap, so the cost has to be checked rather than assumed.
• If you hold ETH on an L2, you have to bridge or withdraw to Ethereum mainnet before paying, which costs time and another transaction.

Where to get ETH

• Any exchange lists ETH. Withdraw specifically on Ethereum mainnet, which is the step people rush.
• Wallet on-ramps in MetaMask, Rainbow or Coinbase Wallet buy ETH directly with a card where cards work — though if your card works, you probably do not need to pay in crypto at all.
• If you already hold ETH on an L2, bridge to mainnet before paying or choose another supported checkout method.

ETH or an accepted stablecoin?

Paying a fixed dollar price with a volatile asset means the real cost is whatever ETH does next — if it rises after you spend it, the subscription quietly cost you more than the sticker price.

If ETH is simply what you have, spending it is reasonable. If you are acquiring something only to pay, an accepted stablecoin method — USDT on TRON or BSC, or USDC on BSC — removes the price question. This checkout does not accept USDC on Ethereum mainnet.

Why the old advice about Ethereum is out of date

For several years the standard guidance was to avoid Ethereum for small payments, and it was correct: at the peak of the 2021 cycle a simple transfer could cost more than a month of a subscription. A great deal of writing on this topic still reflects that period, including an earlier assumption on our own planning list, which is worth admitting because it is the sort of stale fact that quietly misleads people.

Fee reform and the migration of activity to layer 2s changed the picture. A basic mainnet transfer in ordinary conditions now costs cents. It is still a variable cost — congestion pushes it up, and a busy day is a different number from a quiet one — so the correct habit is to check a gas tracker before sending rather than to assume either the old figure or the new one.

• Check the current gas price before you send, the same way you would check a fee on any other network.
• A quoted fee is for the moment you looked. It can change between checking and sending.
• The exact payment amount and the gas fee are separate: the fee comes out of the rest of your wallet balance, not out of what the merchant receives.

Layer 2s, and the trap that comes with them

Most ETH activity now happens on layer 2 networks — Base, Arbitrum, Optimism and others — which settle to Ethereum but are separate chains for the purposes of sending money. If you have bought ETH in the last couple of years through a consumer app, there is a real chance it is sitting on one of them rather than on mainnet.

This matters more than it sounds. With USDT, the classic error is sending TRC-20 to an 0x address, and the mismatched address format gives you a fighting chance of noticing. Between EVM chains there is no such signal: the same address string is valid on all of them. The wallet will not warn you, the transaction will confirm, and the only indication that anything went wrong is that the payment never appears.

So the check is procedural rather than visual. Before sending, read the network named on the payment page, open your wallet, confirm it says Ethereum mainnet, and only then paste the address.

What to do if you have already sent to the wrong chain

Do not send a second transaction until the first is understood, and do not pay anyone offering to recover it — recovery services for this are almost entirely fraudulent, and a second loss on top of the first is a common outcome.

Find the transaction hash and check it on the explorer for the chain you actually sent on. If the funds arrived at an address the recipient controls on that chain, recovery is a support conversation rather than a technical problem. If they went to a contract or to an address nobody holds keys for on that chain, they are not retrievable, and no amount of effort changes that.

• Keep the transaction hash. Every useful conversation about this starts with it.
• Identify which chain the transaction actually landed on before contacting anyone.
• Nobody can reverse a confirmed transaction. Any service claiming otherwise is taking a second payment from you.

Paying with ETH, step by step

1. Choose your plan, term and exact asset/network method on the checkout page — the price is itemised so you can see the gift cost, our markup and the quote/payment handling reserve separately.
2. Enter the email address where you want the redemption code sent. It does not have to match your Claude account.
3. Select the supported ETH method. The private payment page shows the exact amount, QR, receiving address and network.
4. Send the full recipient amount from your wallet or exchange on the exact network displayed.
5. Paste the public transaction ID into the payment page. Submission starts a manual on-chain review and does not mark the order paid.
6. After verification, an operator buys the official gift subscription by hand and emails you the code within 12 hours, usually much sooner.
7. Redeem the code at claude.ai/gift/redeem on the account you want upgraded.
