Domain Name Services & SNS

Solana Name Service (SNS) is a leading domain name system on Solana that allows users to register and manage human-readable .sol domains. As one of the pioneering domain platforms on Solana, SNS offers comprehensive features for replacing complex wallet addresses with memorable domain names, enabling easier transactions and digital identity management. The platform includes robust domain management tools, allowing users to associate wallet addresses, social media profiles, and other digital assets with their domains.SNS stands out for its integration capabilities across the Solana ecosystem, supporting decentralized website hosting through IPFS and Arweave integration. The platform's domains are implemented as NFTs, enabling trading on secondary markets and creating a vibrant domain name economy. With features like Twitter verification and profile customization, SNS has established itself as a cornerstone of digital identity infrastructure on Solana.

AllDomains stands out as a revolutionary domain name service on Solana, allowing users to create and manage custom Top Level Domains (TLDs) directly on-chain. Unlike traditional domain services, AllDomains enables communities, DAOs, and individuals to establish their own unique TLDs, creating a more decentralized and personalized naming ecosystem.The platform bridges Web2 and Web3 functionality by supporting traditional domain registration (starting with .ID domains) while adding NFT capabilities, making domains tradeable assets. With features like renewable registrations to prevent squatting, multi-chain support, and flexible claiming options using SOL or ALLDOMAINS tokens, AllDomains is revolutionizing how we approach domain ownership and digital identity in the Web3 era.

Web3.bio indexes domain names across the major Web3 naming systems — ENS, Basenames on Base, Linea Name Service, and Solana Name Service — and resolves any supported domain to a full identity profile through a unified search interface. As of February 2025, the platform's database covered 3.47 million ENS names, 614,000 Basenames, and 568,000 Linea Name Service entries. A Domain Availability Checker lets users enter keywords and see which Web3 domain names remain available for registration across all supported naming services. This tooling connects directly to the identity graph, so a domain search surfaces not just the domain record but the full web of linked identities — bridging domain discovery and identity exploration in a single query.

3NS is a domain naming protocol that registers .Web3 domains as AI-enabled, tokenized entities across multiple blockchains including Solana, Ethereum, Polygon, and Base. Each domain stores embedded AI logic, workflow definitions, and on-chain governance metadata, allowing it to function as an autonomous agent identity rather than a passive address resolver. Users manage domains through the web3names-app dApp and can publish profile pages tied to the domain's on-chain identity. The protocol positions itself as a distinct alternative to naming services like Solana Name Service or Unstoppable Domains by targeting AI agent discovery rather than human-readable name resolution. Domains build reputation scores and verifiable credentials over time, which counterpart agents use as trust signals before initiating transactions. A MetaMask Snap plugin enables wallet-based domain interaction, and a subgraph indexing layer supports cross-chain domain discovery across supported networks.
