D3

D3 is converting the internet's domain name system into a financial layer. By wrapping traditional domains—.com, .xyz, .ai, and hundreds more—as on-chain assets, D3 lets anyone trade, stake, fractionalize, and lend against domain names the same way DeFi protocols handle tokens. The infrastructure center of gravity is Doma Protocol, a blockchain D3 describes as the first purpose-built for DNS compliance, which launched on mainnet in November 2025. Solana is a primary settlement layer: D3's partnership with InterNetX brings over 46 million registered domains to Solana as tokenized RWAs, and the team has applied with ICANN for the .SOL and .SOLANA top-level domains in partnership with the Solana Foundation.

The Problem D3 Is Solving

The global domain market is estimated at $360 billion—roughly the size of a mid-cap asset class—yet domains trade like it's 2005. Aftermarket transactions clear through escrow intermediaries with multi-day settlement windows, 15–20% platform fees, and no native financial composability. Buyers cannot fractionally own a premium domain or collateralize one for a loan. Ownership is a registry database entry, not a bearer asset. D3's thesis is that domains are the internet's underlying real estate, and that layer should be programmable, liquid, and accessible to anyone with a wallet.

Core Mechanism: Doma Protocol and Name Tokens

Doma Protocol is D3's first-party blockchain layer that acts as the authoritative bridge between ICANN-regulated DNS and on-chain finance. When a registrar or registry partner integrates with Doma, domain ownership records are mirrored as Name Tokens—on-chain representations of the underlying DNS registration that move in lockstep with the off-chain record. The protocol is designed to be ICANN-compliant from the ground up, which matters: traditional domain registries operate under strict contractual obligations to ICANN, and any blockchain layer that ignores those requirements cannot scale through institutional channels.

Name Tokens are not separate speculative assets grafted onto domains. They are representations of live, DNS-functional domain registrations. A domain that resolves in a browser continues to resolve; the Name Token simply adds transferability, composability, and financial programmability on top.

Doma Protocol's mainnet launched in November 2025. Since then the platform has processed more than $120 million in trading volume across 16 million transactions and attracted more than 50,000 wallets. Over 600 domains have been fractionalized.

Solana as Settlement and Marketplace Layer

D3's deepest blockchain integration is with Solana. The company's December 2025 partnership with InterNetX—a domain infrastructure group within IONOS that manages 22 million active domains and 24 million premium listings across 30,000 global partners—routes tokenized domain assets specifically to Solana. The integration uses the Solana Record Service (SRS), which was on devnet as of late 2025 with mainnet launch targeted for early 2026.

Once live, Solana users can hold and transfer domain NFTs directly from Solana-native wallets, trade premium domains on Solana NFT marketplaces, issue domain-backed tokens structured through transparent bonding curves, and access domain-collateralized lending and fractional co-ownership via DeFi protocols.

D3 and the Solana Foundation have also jointly applied for the .SOL and .SOLANA generic top-level domains through ICANN's delegated TLD process. If approved, these would make .sol domain registrations part of the global DNS root—resolvable in any browser without a plugin—while remaining tokenized on Solana.

Features and Products

Interstellar.xyz is D3's consumer-facing marketplace and identity platform, powered by Doma Protocol. It supports both traditional TLDs (.com, .ai, .xyz) and Web3 extensions (.sol, .avax, .shib, .ape) with instant settlement and trading fees approximately 60% lower than the traditional domain aftermarket.

The DNS Connect SDK is a developer toolkit offering unified name resolution across DNS and ENS in a single interface. It supports forward and reverse resolution, wallet-to-name mapping, and works across Node.js 18+ and modern browsers.

The D3 API gives third-party applications full access to domain search, AI-powered name recommendations, Name Token minting, pricing data, and reverse resolution. Partners can integrate domain sales directly into their products through three channels: a simple affiliate redirect (D3 Link), an embeddable widget (D3 Embed), or full API integration.

In June 2025, D3 launched a $1M USDC Developer Fund to accelerate ecosystem builders on the Doma testnet, targeting the $360 billion domain sector's potential for on-chain innovation.

Tokens and Assets

D3's primary on-chain assets are Name Tokens—fungible or non-fungible representations of specific domain registrations. Premium domains can be fractionalized into smaller tradable units via bonding curves, enabling collective ownership of high-value names that would otherwise be inaccessible to most participants. The protocol also supports domain-backed liquidity pools, automated yield for liquidity providers, and domain bundling into structured products. There is no disclosed native governance or utility token as of mid-2026.

Audits and Security

The Doma Protocol uses EIP-712 signatures for wallet mapping operations, expiring signatures with a default 5-minute validity window, and on-chain settlement to eliminate custodial risk. No third-party smart contract audits have been publicly disclosed in available documentation.

Team

D3 was co-founded by Fred Hsu (CEO) and Michael Ho (CBO), who lead strategy and business development respectively. Inder Singh (VP Product) leads product development; Mark Trang (CMO) runs marketing. In January 2026, Bob Mountain joined as Chief Commercial and Revenue Officer, bringing nearly 20 years of domain aftermarket experience from GoDaddy. The team claims 30+ years of combined domain industry expertise.

Solana Fit

Domains are one of the few genuinely large real-world asset classes not yet on-chain at scale. D3's Solana strategy targets three distinct opportunities: settlement throughput (Solana's speed and fee structure suit high-frequency domain microtrading), RWA composability (domain-backed lending and fractional ownership plug directly into Solana DeFi), and identity infrastructure (an ICANN-approved .SOLANA TLD would make blockchain-native domains browser-resolvable globally). The InterNetX partnership alone represents 46 million domains in the potential pipeline—if even a fraction of those are actively tokenized on Solana, it would represent one of the largest RWA deployments on any chain by asset count.

D3's $25 million Series A, led by Paradigm and joined by Coinbase Ventures, Sandeep Nailwal (Polygon Labs co-founder), Dharmesh Shah (HubSpot founder), and Richard Kirkendall (Namecheap CEO), positions it as the best-capitalized team attempting to bring traditional domain infrastructure on-chain at institutional scale.
