Sirdio

Domain registration, paid in crypto

Register a domain. Nothing else attached.

No social logins, no linked accounts, no card on file. Sirdio asks only for what the registry needs, takes payment in crypto, and gets your registration moving as soon as the payment confirms.

Three steps. No detours.

  1. Find a name

    Search above to see what a name costs per year and whether it’s free. For .ax names, our team confirms availability with the registry before registering.

  2. Create an account

    An email address and a password, then the contact details a registry needs to put the domain in your name. A few minutes, start to finish.

  3. Pay in crypto

    Pick a coin and send the exact amount shown. Once the payment is confirmed on-chain, .st domains are registered automatically; .ax registrations are completed by our team.

Private by default

We keep the list short on purpose.

What we ask for

  • An email address and a password
  • Registrant contact details, because registries require them
  • A crypto payment for each order

What we don’t

  • Sign-in through Google, Apple or Facebook
  • Connections to your other accounts or apps
  • Card numbers or bank details
  • Ad trackers or analytics on this site

Your account is protected with two-factor sign-in through any authenticator app. On .st domains, WHOIS privacy keeps your contact details out of public lookups.

Payment

Pay from the wallet you already use.

  • BTC Bitcoin
  • LTC Litecoin
  • ETH Ethereum
  • USDT Tether
  • USDC USD Coin

Exact amount, locked rate

Every invoice shows exactly what to send. The exchange rate holds for 30 minutes.

Matched automatically

We confirm each payment on-chain and check it against two independent sources before it’s booked.

Nothing to connect

No payment accounts, no stored cards. Send from any wallet or exchange that can pay to an address.
