A dash means we found no evidence of support, not that support is impossible. Coin availability at checkout can differ by country and product.
Payment networks
Which network each coin is accepted on, exactly as Unstoppable Domains documents it. A coin and a network appearing in the same record does not by itself mean the two go together.
Each pairing above is taken from Unstoppable Domains’s own documentation or its named gateway’s. Absence means we found no evidence, not that a chain will fail.
Pay on the cheapest network offered — Unstoppable Domains receives the same amount either way, so the fee comes out of your side. Our network comparison covers which to pick.

Payment notes
The support article "How to Buy a Domain" is specific about the crypto route. "For crypto payments, Unstoppable Domains uses the Coinbase Onchain Payment Protocol. If you choose to pay with Coinbase Exchange, you'll have access to hundreds of supported currencies, including ETH, MATIC, USDC, USDT, DAI, ADA, SOL, and more." From your own wallet — WalletConnect, MetaMask, Coinbase Wallet and others — "only Base, Ethereum, and Polygon are currently accepted", which is the network list recorded for the Coinbase route. Helio is offered as a separate method with "similar steps"; Helio's Solana Pay checkout settles in USDC on Solana by default, which is why Solana appears in the network list, attributed to the gateway rather than to a statement by Unstoppable Domains. Crypto.com is listed as a further method without detail. Card payments run through Stripe with a country list; crypto has none. The article notes a two-hour lock on a domain after a failed crypto payment before you can try again.
Refunds
Not documented for crypto specifically in the payment article. Domain registrations are generally final once processed; Unstoppable Domains' terms govern refunds, and a Coinbase or Helio payment would be refunded by the merchant rather than reversed on chain.
Stablecoin refunds are outbound payments a merchant chooses to send, not automatic reversals. There is no chargeback.
Unstoppable Domains is best known for names that end in .crypto, which this directory does not cover. It is here because the same checkout now sells ordinary .com-style domains, and the support article documents the stablecoin route better than most registrars document anything.
What the merchant says
Payment methods: card, PayPal, cryptocurrency, Crypto.com, Helio. Crypto runs through Coinbase’s Onchain Payment Protocol; through a Coinbase account you can use “hundreds of supported currencies, including ETH, MATIC, USDC, USDT, DAI”; from your own wallet, “only Base, Ethereum, and Polygon are currently accepted”, and Bitcoin-family coins are no longer taken that way. You pay your own gas. That is a coin list and a network list from the merchant, which is rarer in the domains category than it should be.
Two crypto doors
Coinbase for the EVM chains — Base is the cheap choice for a $10 domain — and Helio for Solana. The merchant names Helio but not what it carries; Helio’s own documentation settles to USDC on Solana by default, and the record attributes Solana to the gateway on that basis.
The two-hour lock
If a crypto payment fails, the domain can show as taken for up to two hours before you can try again. On a name you care about that is worth knowing before you send from a chain that might be congested.

Verification
Verified Verified September 2026
An editor confirmed these payment options against the sources listed below.
The merchant's own support article, modified 12 September 2025, names USDC, USDT and DAI among the assets accepted through the Coinbase Onchain Payment Protocol and names Base, Ethereum and Polygon as the only networks accepted from a self-custodial wallet. That is merchant documentation naming coin and network, sufficient for a verified status without a live purchase, which we did not make. Solana is recorded on the strength of the merchant naming Helio as a payment method and Helio's documented USDC-on-Solana default; the merchant does not say which coins the Helio route carries, and the record says so. The processor is mapped to our Coinbase Commerce profile, Coinbase Business being its successor. The operating company is from the terms of service. StablecoinSpend has no relationship with Unstoppable Domains, Coinbase or Circle.

Added after reading the merchant's own support article naming USDC, USDT and DAI via the Coinbase Onchain Payment Protocol and Base, Ethereum and Polygon for self-custodial wallets.
Limitations
- From your own wallet, only Base, Ethereum and Polygon are accepted; Bitcoin, Dogecoin, Litecoin and Bitcoin Cash are no longer accepted from self-custodial wallets.
- You pay the gas on your own transaction "on both Coinbase Exchange and your own personal wallet", per the support article.
- Solana is reached through the Helio option, whose default settlement is USDC; the merchant names Helio but not the coins it carries.
- A failed crypto purchase can leave the domain showing as taken for up to two hours before you can retry.
