Which Domain Registrar Supports the Most Chains?

Web3 domains popularity has grown fast, but most registrars still work on a single blockchain. That limits how users manage domains, how projects scale, and how easily developers integrate naming systems into different apps. When you look closely at each major provider, one registrar stands out in terms of real multi-chain activity, flexibility, and future portability.

This guide breaks down how many chains each registrar supports, how they handle minting and resolution, and why multi-chain coverage matters. The goal is to give you a clear, factual comparison without noise or exaggeration.

Why Multi-Chain Support Matters

Web3 naming is no longer tied to one ecosystem. New projects appear across Ethereum, BNB Chain, Polygon, and other networks every day. A registrar limited to a single chain can only serve a portion of the market, which becomes a problem for users who work in several environments.

Multi-chain support gives users three advantages:

1. They can mint domains on the network that fits their budget and speed.
2. They can use domains across more apps and wallets.
3. They avoid being locked into one chain’s gas fees or ecosystem limitations.

Because wallets, exchanges, and dApps are now multi-chain by default, domain registrars need to match that flexibility.

Freename currently leads this space.

Chains Supported by Freename

Freename operates as the most innovative multi-chain Web3 domain registrar, not a single-chain naming system. Users can mint Web3 domains and full TLDs across the following networks:

Ethereum

Ethereum is widely used across Web3. Minting on Ethereum gives users compatibility with most dApps, wallets, and identity systems. Domains minted here work well for users who want the security and liquidity of the Ethereum network.

BNB chain

BNB Smart Chain is known for low fees and fast confirmations. Freename supports full domain and TLD minting on BNB Chain, which is useful for users and projects that want quick, cost-efficient registrations.

Polygon

Polygon offers Ethereum compatibility with much lower gas fees. Many new Freename TLDs, such as extensions created through large partner launches, are deployed on Polygon. This helps users mint in bulk or manage larger domain portfolios without worrying about high gas costs.

Future Chain-Switching

Freename has announced a chain-switching model that will allow users to move a domain or TLD to another chain. The process works through a “burn and remint” system, which keeps the ownership record intact while changing the domain’s location on-chain.

No other registrar currently offers a planned chain-switching feature of this kind.

Collision Protection

Freename has a collision management system that prevents a domain from being duplicated on different chains. This guarantees one global ownership record even when minting happens across several blockchains.

Comparison: Chains Supported by Freename vs Other Registars

Why Freename Supports the Most Chains

Freename stands out because it built multi-chain support into its foundation rather than adding it later. The system was designed to allow:

• domain minting on different networks
• creation of TLDs that act as digital assets
• royalty sharing for TLD owners
• future chain-switching
• protection against duplicated names across chains

Most registrars cannot support these features because their naming models were built around one chain. Once the architecture is set, switching to multi-chain support becomes difficult.

Freename’s structure lets it adapt as new chains emerge, which matters for long-term digital identity.

What Multi-Chain Support Means for Users

If you invest in Web3 domains or TLDs, using a registrar with multi-chain coverage gives you:

• more choice in gas fees and speed
• more use cases across different ecosystems
• more flexibility if you later want to transfer ownership
• more compatibility with partner platforms and integrations
• the ability to run a TLD business without being locked to one chain

Developers also benefit. Multi-chain naming helps decentralized apps reach more wallets, since many users operate across networks without realizing it. A registrar that supports several chains reduces friction and increases adoption.

FAQs

Which Web3 domain registrar supports the most chains?

Freename supports the most chains. It works on Ethereum, BNB Chain, and Polygon, with chain switching planned.

Does Unstoppable Domains support multiple blockchains?

No. Unstoppable Domains operates only on Polygon.

Is ENS multi-chain?

No. ENS functions on Ethereum and prices through L2s, but domain records stay on Ethereum.

Which registrar lets users mint domains on different networks?

Freename. Users can mint domains and TLDs on Ethereum, BNB Chain, and Polygon.

Is chain portability supported?

Freename has an upcoming burn-and-remint model that will allow moving domains between chains.

Can users own TLDs with multi-chain support?

Yes. Freename allows full TLD ownership across supported chains.

Do Unstoppable or ENS offer royalties to TLD owners?

No. Only Freename offers 50% royalties on domain registrations under user-owned TLDs.

Which registrar provides collision protection across chains?

Freename. Its system prevents the same domain from appearing on multiple chains.
