Buy a domain with USDC
Buying a domain with USDC means settling a registrar invoice or prepaid account balance in USD Coin (USDC), a US-dollar–pegged stablecoin issued by regulated entities on multiple blockchains. Like USDT payments, the domain registered is a standard DNS name; only the payment rail differs.[1]

What USDC is
USDC is a stablecoin intended to remain close to one US dollar. It is issued as separate tokens on different networks. Sending USDC on Base to an Ethereum-only invoice, or confusing USDC with USDT, are common failure modes.
Networks
As of November 2026, domain checkouts commonly mention some combination of:
- Base — used by Porkbun’s Coinbase Business / x402 USDC flow and by StableDomains.[2][3]
- Ethereum (ERC-20) — widely supported in wallet software.
- Solana, Polygon, Arbitrum, BNB Smart Chain — listed by multi-chain account-funding desks such as NiceNIC; StableDomains also lists Solana and several EVM chains for USDC/USDT.[4][3]
- Tron (TRC-20) — NiceNIC documents USDC on Tron among other networks; not every registrar offers it.[4]
Gas and bridging costs differ sharply between chains. Prefer the network printed on the live invoice rather than moving funds through an unnecessary bridge.
How checkout usually works
Two patterns appear:
- Direct invoice — the order quotes an exact USDC amount and address (or an x402 / Coinbase payment URL). After confirmations, the domain registers.
- Account credit — USDC tops up a prepaid balance (Porkbun credit, NiceNIC funds, Dynadot balance), which is then spent on registrations and renewals.[2][4]
Dynadot’s help centre states that crypto payments (BTC, USDC, USDT) may take up to two hours to confirm, that the payment network must be correct, and that crypto refunds are issued as account credit.[5]
Pitfalls
- Wrong chain or wrong stablecoin (USDC versus USDT).
- Exchange withdrawal fees reducing the amount received.
- Assuming renewals can auto-charge a wallet — many shops require a fresh invoice or prepaid credit for each renewal.
- Processor KYC thresholds on hosted checkouts (for example BitPay-style flows at other registrars) even when the asset is a stablecoin.
Providers that accept USDC for domains
| Provider | What was verified | Source note |
|---|---|---|
| Dynadot | Supports USDC (with BTC and USDT) at crypto checkout; select the network shown by the processor. | [5] |
| NiceNIC | USDC account funding on Ethereum, Tron, Polygon, Solana, Arbitrum One and BNB Smart Chain; balance buys domains. | [4] |
| Porkbun↗ | USDC on Base via Coinbase Business / x402 for account credit or direct API purchases; free WHOIS privacy on supported TLDs. | [2] |
| StableDomains↗ | USDC (and USDT) on Base, Ethereum, Arbitrum, Polygon, HyperEVM, BNB Chain or Solana; card via Stripe; free WHOIS privacy advertised. | [3] |
Namecheap’s BitPay top-up path is Bitcoin-oriented account credit rather than a documented USDC domain checkout, so it is covered under general crypto guides instead of this USDC list.[6]
