Doma FAQ

Welcome to the Doma FAQ! This guide will help you understand how D3, Doma, and the Doma Protocol work together to power domain tokenization, management, and trading in Web3.

D3 is where you buy or reserve domains (including Expressions of Interest for future TLDs like .ape, .doge, or .magic). You can then tokenize these domains to unlock Web3 capabilities.

Doma is where you manage your tokenized domains across registrars — you can list them, place and accept offers, bridge them across chains, detokenize them, and monitor ownership status. Doma acts as your domain wallet and portfolio hub.

All flows are currently on Testnet, meaning no real funds are involved, and data may be reset at any time. Once Mainnet launches, you’ll use the exact same flows with real registrars, real domains, and real payments.

This FAQ is designed for developers, domainers, and early partners exploring the future of tokenized domains. If you have questions beyond this FAQ, please reach out to [email protected] or join our Discord.

TestNet D3

What is Testnet.D3.app?

Testnet D3.app is a registrar created to test and prove out the Doma Protocol. You can think of it as a real working sandbox where you can experiment with tokenizing domains. It is designed for early users and developers to test flows, provide feedback, and contribute to building the ecosystem.

What is an EOI domain on D3?

EOI stands for Expression of Interest. On D3, you can reserve domains in future top-level domains (TLDs) that have not yet launched — for example, .ape, .doge, or .magic. These TLDs are expected to go live in Summer 2026, pending ICANN approval. When the registry for these TLDs gets approved, folks who have placed an EOI will get first dibs on claiming those domains. What happens after I buy or reserve a domain on D3? After you purchase a domain on D3, you have the option to tokenize it. Tokenization involves transforming your domain into an NFT representation, making it tradable and manageable on Web3 marketplaces and systems.

Where does my tokenized domain go after D3?

Once tokenized on D3, the domain is automatically made available in Doma, a separate platform built for managing, claiming, bridging, and listing tokenized domains across the ecosystem. Doma acts as an aggregator, showing tokenized domains from any registrar that supports Doma Protocol.

Is Testnet.D3.app Testnet chains and currency?

Yes, D3 is currently running on Testnet. That means domain purchases, tokenizations, and payments are all test transactions, no real money is exchanged, and domains on Testnet are not production domains.

Why does D3 exist?

The D3 registrar was created as a way to "dogfood" Doma Protocol and get a head start on onboarding real registrars by demonstrating how domain tokenization can work. It is a working playground, but one with a purpose: to make sure the experience is smooth before going to the Mainnet with other partners.

Who is D3 for?

Right now, D3 is focused on:

  • Developers building on Doma Protocol

  • Domainers who want to explore tokenization

  • Partners who want to test integrations before going live

Remember: D3 is Testnet, so it’s perfect for experimentation.

Doma and Differences with D3

What is Doma?

Doma is your universal domain management hub designed specifically for tokenized domains across various registrars. You cannot directly buy or register new domains on Doma. Instead, it serves as a portfolio manager and Web3 domain wallet, allowing you to list domains for sale, place offers, accept offers, claim ownership, bridge domains to other chains, detokenize them, and track their activity and status in one place.

How does Doma get tokenized domains?

Doma receives tokenized domains from registrars that integrate with the Doma Protocol — for example, registrars like D3, Encirca, Nicnames, and others. Once a domain is tokenized with any of these registrars, it automatically appears on Doma and becomes available for further actions, such as listing on a marketplace or claiming it under your wallet.

What is the difference between D3 and Doma?

Think of D3 as the platform where you can buy or reserve a domain name — especially for domains launching under Expressions of Interest (EOI) programs targeted around Summer 2026. After you tokenize the domain through D3, you can then manage it on Doma. That means you can list it for sale, bridge it across chains, claim it, or monitor its analytics and ownership status from within Doma.

How does multi-wallet and multi-chain support work?

Doma allows you to link multiple wallets to a single email address, making it simple to manage your entire domain portfolio from one unified account. With this feature, you can control domains across supported blockchains, including Base, the Doma chain, and soon Solana. The same Doma account gives you seamless oversight of your domains no matter which wallet or chain they reside on.

What if I lose my wallet or change my email?

If you ever lose access to your wallet, you can reconnect a new one after verifying ownership of your linked email address, which ensures the security of your domain portfolio. Similarly, if you change your email address, you will be prompted to verify the new email before regaining access to manage your domains.

Do I pay gas fees?

Yes, when operating on Mainnet, you will be responsible for covering standard blockchain gas fees, just like with most decentralized services. On Testnet, however, you can use faucet tokens to simulate transactions without spending real crypto. There are future plans under consideration for D3 to potentially subsidize these gas fees, though nothing has been confirmed yet.

Is Doma secure?

Doma is built with a strong focus on security. No one can list, transfer, or bridge your domain without you signing the relevant transaction through your connected wallet. In addition, Doma follows robust compliance frameworks and uses secure wallet-based authentication to protect your assets.

How is the registrar notified after a claim?

When you claim a domain on Doma, the platform automatically communicates with the registrar, for example, D3, to update their records, ensuring you are listed as the official owner of the domain. This process guarantees compliance with ICANN rules and helps maintain accuracy in the registrar’s ownership records.

What happens during Mainnet migration?

When Doma transitions from Testnet to Mainnet, all data and domains on the Testnet will stay on the Testnet. Your user flows — like listing or claiming domains — will continue to work the same way on Mainnet, but with real registrars and live production data. Testnet domains and balances will not transfer to Mainnet.

Who owns my data on Doma?

You are the owner of your domain data. Doma and the integrated registrars only store data that is strictly necessary for compliance, domain transfers, and user support. This information is never sold to third parties, preserving your data privacy.

Can I withdraw real funds?

No, you cannot withdraw or move real funds while on Testnet because all balances and domains are strictly for testing. Once Doma goes live on Mainnet, standard crypto withdrawal options will be available depending on the supported marketplace integrations.

Which chains does Doma prioritize?

Currently, Doma fully supports both the Doma chain and Base. Solana is prioritized next for bridging and future integrations. Beyond that, other EVM-compatible chains could be added over time as Doma continues to expand its ecosystem.

Doma Testnet

Is Doma on Testnet or Mainnet?

At the moment, Doma is operating on Testnet. This means that any domains you buy, tokenize, bridge, or claim within the platform are purely for testing and learning purposes. These domains are not real production domains and cannot be used on the global internet. They serve as a way for users to practice and familiarize themselves with the system before the full Mainnet launch.

Is the money real?

No, there is no real money involved on Testnet. Instead, Doma uses test currencies, such as Test ETH or Test USDC, which you can receive through faucets. These tokens are only for simulating transactions and have no actual monetary value or exchangeability.

Will my Testnet domains carry over to Mainnet?

No, your Testnet domains will not transfer to Mainnet. Once Doma goes live on Mainnet, you will start with a clean slate, working with actual registrars and authentic domains. Think of Testnet domains as a safe playground or temporary “training wheels” to help you get comfortable with the process before handling real assets.

Why do I see faucets mentioned in the dashboard?

You may see references to faucets on the Doma dashboard. Faucets are tools that provide you with free Testnet tokens so you can pay for simulated gas fees during testing. These faucet tokens have zero monetary value and are strictly for use in the Testnet environment.

Could D3 cover gas fees in the future?

D3 is actively exploring options to potentially subsidize gas fees for end users once the platform is in production on Mainnet. However, during Testnet, you will still need to use faucet tokens to cover any simulated gas fees. No final decision has been made yet for Mainnet regarding fee subsidies.

Are EOI (Expression of Interest) domains real?

No, EOI domains that you see on Testnet are not real. They serve only as placeholders and do not carry any legal standing today. These domains will remain in placeholder status until the related registry is fully approved by ICANN, which is expected around Summer 2026.

Any legal disclaimers I should know?

Yes — it is important to understand that any domains, balances, offers, or listings on Testnet are strictly for development, quality assurance, and demonstration purposes only. There is no warranty, no transfer of actual ownership, and no financial settlement tied to Testnet assets. You should always treat Testnet activities and assets as purely experimental.

Buying, Selling, Bridging and Multi-Chain

How do I buy a tokenized domain?

To buy a tokenized domain, you start by purchasing a domain through a participating registrar such as D3, Encirca, or Nicnames. Once the domain is tokenized, you can list it on marketplaces, including Doma, OpenSea, or Magic Eden. Other users interested in your domain can then buy it directly from these marketplaces, giving you options to sell or trade.

How to buy and tokenize domains on Testnet

  1. Go to testnet d3.app at https://testnet.d3.app/

  • Create an account (or log in)

  • Link your wallet

  1. Use the search bar to find a domain

  • Search for domains ending in: .com, .ai, .io, .xyz, .shib, .core, .ape, .vic

  • At this moment, only Web2 domains (like .com, .ai, .io, .xyz) can interact with the Doma Testnet.

  1. Buy with test credit card

  1. Tokenize your domain

  • After buying, choose where to tokenize:

    • Doma Testnet

    • Sepolia Testnet

    • Base Testnet

  • This turns your domain into an NFT linked to your wallet

Note: Easiest method is to tokenize directly to the Doma Testnet. This will require no bridging.

  1. See it on Doma Testnet

ALTERNATIVE: Buy with Sepolia ETH

  • Mine Sepolia ETH

  • Bridge Sepolia ETH to Doma Testnet

  • Use it to buy domains

Tip: Use the same wallet across D3 and Doma so everything appears correctly.

What happens after I buy a tokenized domain?

After purchasing a tokenized domain NFT on a marketplace, you will need to claim it on Doma. The claim process links your wallet to the domain and requires you to provide your email address. This allows the registrar to finalize the ownership records and ensures that the domain is properly attributed to you on-chain and in registrar systems.

Can I place or accept offers?

Absolutely — you can place offers or bids on tokenized domains through Doma. If you are the owner of a tokenized domain, you can also accept offers directly from your Doma dashboard. Once an offer is accepted, the transaction is confirmed and finalized on-chain, ensuring a secure and transparent transfer of ownership.

How do I detokenize a domain?

Detokenizing a domain means you remove the token from the blockchain, reverting the ownership record back to a traditional registrar-only state. After you detokenize, your domain cannot be listed or traded on Web3 marketplaces until you choose to re-tokenize it again. This provides flexibility if you wish to keep the domain purely within the traditional domain system.

What happens if my claim fails?

If a claim fails because of a wrong email, wallet mismatch, or other issues, you can always restart the claim process directly on Doma. In certain situations, the registrar may ask you to go through manual verification steps to confirm your ownership before finalizing the claim.

What is bridging in Doma?

Bridging in Doma allows you to move your domain token from one blockchain network to another. For example, you might bridge a domain token from the Doma chain to Base or to Solana. Bridging gives you access to different liquidity pools and marketplaces on those networks, expanding your trading and ownership opportunities.

How do I bridge a tokenized domain?

To bridge a tokenized domain, go to your Doma Dashboard, select the domain you wish to bridge, click the Bridge option, then choose your target chain and target wallet. After confirming the transaction, you’ll wait for the bridge to finalize. If you are on Testnet, you can use faucet tokens to pay for the necessary gas fees, making it simple to experiment before moving to Mainnet.

Which chains are supported for bridging?

Today, Doma supports bridging across the Doma chain and Base. Solana is the next chain prioritized for full bridging support, with other EVM-compatible chains also being evaluated for future integrations.

Do I pay gas fees when bridging?

Yes, you do pay network gas fees when bridging your domain. On Testnet, faucet tokens are provided for free to cover these simulated gas fees. For Mainnet, D3 is exploring the possibility of subsidizing user gas fees, although this is not yet confirmed.

Can I bridge directly after buying on OpenSea or Magic Eden?

Yes, you can bridge your domain to another supported chain at any time after you claim it on Doma. This flexibility unlocks broader liquidity and trading opportunities across supported blockchain networks, giving you more ways to manage and profit from your tokenized domains.

Who do I contact for partnerships?

If you are interested in registrar integrations or exploring enterprise-level collaboration opportunities, you can email [email protected]. The partnerships team will be happy to discuss opportunities with you.

Is Doma on Mainnet?

Currently, Doma is only on Testnet. All data and funds within the platform are simulated and can be reset or refreshed at any time as part of the testing environment.

Are Testnet funds real?

No, Testnet funds are not real. Testnet uses faucet-based tokens with no monetary value, so you cannot withdraw or convert them to actual funds. They are intended purely for testing and learning.

Are EOI domains guaranteed?

No, EOI (Expression of Interest) domains, such as those ending in .ape, are not guaranteed. These domains are still pending ICANN approval, with a target timeline around Summer 2026, but there is no legal guarantee until final approval is in place.

Can I move my Testnet domains to Mainnet?

No, domains on Testnet will remain on Testnet. When Doma transitions to Mainnet, you will need to re-tokenize your domains with real registrars and production-ready domain names.

Who owns my data on Doma?

You own your data on Doma. Both registrars and Doma only store the data needed to support claims, transfers, and compliance. They do not sell or share user data with third parties.

Can I withdraw from Doma?

Withdrawals are not available on Testnet since it uses purely simulated assets. When Doma is live on Mainnet, withdrawals will follow standard crypto marketplace protocols.

Is my domain secure on Doma?

Yes, Doma is built with a strong focus on security. Only your connected wallet can sign transactions, ensuring you are in control of listing, bridging, and claiming your domains. In addition, Doma uses strict compliance frameworks to protect your assets.

What if Testnet resets?

Since Testnet is a developer sandbox, all assets there are temporary and data loss is possible if the network resets. You should treat anything on Testnet as experimental and not permanent.

Will there be gas subsidies on Mainnet?

It is possible that D3 may subsidize gas fees in the future once Mainnet is live, but this has not yet been confirmed. For now, on Testnet, you will continue to use faucet-supplied tokens to cover gas fees.
