A domain registrar built for stablecoins and AI agents

StableDomains.net lets people and software buy domain names with crypto stablecoins. Pay in USDC or USDT on Base, Ethereum, Arbitrum, Polygon, HyperEVM, BNB Chain or Solana, and the domain is registered as soon as the payment confirms. There are no card forms and no account to create: buy as a guest, or sign in with your wallet.

It is built agent-first. Every action on this page is also available to AI agents through a documented REST API, the x402 payment protocol for pay-per-request access in USDC, and a Model Context Protocol (MCP) server that agents can connect to in one step. An agent can search for a name, get a quote, pay and receive the domain without a human in the loop.

Alongside registration you get free tools: a name generator, a domain value estimator, WHOIS lookup, a DNS and email checker, and a list of expiring domains with backlinks. See the agent and API docs to get started.

Frequently asked questions

Can I buy a domain with USDC or USDT?

Yes. StableDomains.net sells and renews domains for USDC and USDT stablecoins. Search a name, pick a chain and token, and pay from any wallet app, by QR code, or by card through Coinbase Onramp. Registration starts automatically once the payment confirms on-chain.

Which blockchains are supported?

Seven: Base, Ethereum, Arbitrum, Polygon, HyperEVM, BNB Chain (BSC) and Solana. USDC works on all of them and USDT where the token exists. Gasless x402 payments use USDC on Base.

Do I need an account?

No. You can buy as a guest and add an email for your receipt. You can also sign in with an Ethereum wallet (SIWE), and recover past orders by email at any time.

How do AI agents buy domains here?

Agents can use the REST API (OpenAPI spec at /api/openapi.json), pay per request with the x402 protocol (HTTP 402 Payment Required), or connect to our MCP server at /api/mcp to search, quote and register domains as tool calls.

What is the MCP server?

The Model Context Protocol server exposes tools such as domain search, quotes, order creation, name suggestions and expiring-domain lookups, so assistants like Claude or Cursor can buy a domain without custom code.

Is WHOIS privacy included?

Yes, WHOIS privacy is free on every domain where the registry allows it.
