D3

D3 is building the financial infrastructure layer for internet domains — transforming what has historically been a static, illiquid asset class into programmable, tradeable onchain collateral. Founded in August 2023 and operating under the tagline "The Internet's Domain Layer, Tokenized," D3 is the company behind Doma Protocol, the first DNS-compliant blockchain purpose-built for domain tokenization at internet scale.

The core idea behind DomainFi — D3's term for this emerging category — is straightforward: the internet's 362 million+ registered domains represent hundreds of billions of dollars in locked value, yet they remain nearly impossible to trade quickly, fractionalize, or use as productive financial instruments. Premium domains worth millions can take months to transact through traditional escrow channels. Owners have no mechanism to access liquidity without an outright sale. D3 is building the infrastructure to change that.

Doma Protocol

Doma Protocol is D3's flagship product and the core of its DomainFi infrastructure thesis. The protocol functions as the authoritative record layer for tokenized domains, maintaining synchronized state across multiple blockchains while remaining ICANN-compliant — meaning tokenized domains retain their real DNS functionality and continue to resolve as ordinary .com, .ai, or .xyz addresses.

The protocol employs a three-layer architecture. A Registrar Bridge and Toolkit gives traditional domain registrars APIs to connect their existing systems to Doma Chain, synchronizing events bidirectionally between onchain state and registrar infrastructure. Doma Chain itself serves as the canonical onchain record for all tokenized domains and coordinates state across supported blockchains using ERC7786 cross-chain messaging. On-Chain Domain Capabilities — smart contracts on Solana, Base, Ethereum, and Avalanche — then enable DomainFi applications including fractionalization, DEX trading, collateralization, and yield generation.

The protocol's cross-chain layer uses LayerZero for messaging and Celestia for data availability, allowing a domain tokenized on one chain to remain accessible across others without wrapped asset risk.

Mainnet Launch and Growth

Doma Protocol's mainnet went live on November 25, 2025, with an initial validator set comprising D3, Conduit, and early registrar partners. The Asset Origination phase — during which the first premium domain tokens were minted — began December 1, 2025.

Registrar adoption was significant from launch. Partners including InterNetX, NicNames, Rumahweb, and EnCirca collectively provide access to over 30 million domains eligible for tokenization. The protocol processed more than $76 million in trading volume across 10 million transactions in its first weeks, supported by 46,000 unique wallets and 425+ fractionalized domain launches. By mid-2026 those figures had grown to over $120 million in cumulative volume across 16 million transactions, with more than 600 fractionalized domains and 50,000 active wallets.

Solana at the Center

Solana is one of D3's primary blockchain partners and a first-class deployment chain for Doma Protocol. In January 2025, D3 and the Solana Foundation announced they are collaborating on infrastructure to bridge Web2 and Web3 domains on Solana's network, including joint applications for the .SOL and .SOLANA ICANN top-level domains. The relationship positions Solana as a primary venue for domain tokenization given its throughput characteristics and its existing name service ecosystem.

That partnership deepened in December 2025, when D3 and European domain registrar InterNetX unveiled at Solana Breakpoint 2025 a deal to bridge over 46 million domains to Solana as tokenized real-world assets via Doma Protocol — placing one of the largest single-registrar domain migrations in crypto history squarely on Solana.

Funding and Backers

D3 closed a $25 million Series A in January 2025, led by Paradigm. The round included Coinbase Ventures, Polygon Labs co-founder Sandeep Nailwal, HubSpot founder Dharmesh Shah, and Namecheap CEO Richard Kirkendall — a combination of crypto-native and Web2 domain industry credibility that reflects D3's positioning as a crossover infrastructure play rather than a purely crypto-native project.

Expanding the Product Suite

D3 has continued building beyond the core protocol. At its Dominion 2026 conference in Las Vegas in April 2026, the company announced two new products targeting institutional and AI-era use cases.

Domain Asset Vehicles (DAVs) bundle institutional domain portfolios into a single tokenized instrument, enabling shared onchain ownership of a portfolio without requiring individual domain sales. Revenue from domain sales within the portfolio flows through to token holders, giving large registrars and portfolio holders a mechanism to unlock liquidity at scale without divesting core assets. CEO Fred Hsu framed the product directly: "DAVs give institutional portfolio owners a way to access liquidity at scale without giving up control of the assets that define their business."

The Doma Agentic Engine is a complementary AI product that provides domain owners with real-time analysis of how AI agents interpret and interact with their domains, identifying content gaps and offering automated remediation tools. The product targets domain owners looking to improve their assets' discoverability as AI agents increasingly serve as the primary discovery layer for web content.

D3 has also integrated with ENS (Ethereum Name Service), allowing domain owners to use tokenized DNS domains as ENS names without DNSSEC setup — initially available on Ethereum testnet with mainnet deployment planned following further testing rounds.

Why It Matters

The global domain aftermarket carries an estimated $340–360 billion in notional value, but historical infrastructure has made trading slow, opaque, and capital-inefficient. D3 is building the full stack — chain, registrar APIs, cross-chain bridges, DeFi primitives, and institutional products — to make that value composable and liquid without breaking the DNS infrastructure the internet runs on.

For Solana specifically, D3's traction represents one of the largest real-world asset tokenization efforts deployed on the network, bringing institutional-grade domain portfolios into direct contact with Solana's DeFi rails and broader token ecosystem.
