What is Lime.dev?
Web3 identity infrastructure on Ethereum Name Service. Free names for everyone—enterprise infrastructure for companies.
Lime.dev is a Web3 identity infrastructure provider built on the Ethereum Name Service (ENS) ecosystem. We design and operate a hybrid ENS resolver that enables projects, companies, L2 networks, exchanges, and Web3 platforms to issue and manage ENS-compatible identities at scale—without gas costs for end users.
At the same time, Lime offers a fully free Web3 identity service for individual users, allowing anyone to get an ENS-compatible subname instantly—no transactions, no fees, no blockchain friction.
Lime is an infrastructure layer that uses ENS standards and extends ENS capabilities, making it more accessible—effectively free.
Why Lime exists
Web3 identity must become universal. If every user must pay gas and complete transactions before getting a readable name, mass adoption slows down. Lime solves this by removing gas from the identity issuance process and enabling mass issuance of ENS-compatible names.
Our goal is to make Web3 identity accessible to everyone while maintaining ENS compatibility.
Hybrid (Lime) vs Onchain
Hybrid (Lime)
- ✓Free to claim and manage fully
- ✓No gas for updates—signature only
- ✓You choose what to write onchain
- ✓Update via API
Onchain
- •Paid registration fee + gas
- •Gas per any action, including updates
- •Annual Renewal fee + gas required
- •No API only onchain updates
Get, update, modify your Web3 name without paying gas and fully free. When you want a permanent record on Ethereum, you can write onchain. That's the power of hybrid resolution.
Web3 identity does not scale
Ethereum addresses are unreadable to humans. ENS solves this with readable names like name.eth. However, the traditional ENS model has limitations:
- •Registration requires gas payment
- •Onchain updates are expensive
- •Mass issuance is operationally complex
- •UX friction complicates onboarding
- •Companies need namespace management tools
For mass adoption, Web3 identity must be:
- ✓ Free, instant, scalable, ENS-compatible
- ✓ Protected against spoofing and phishing
This is exactly where Lime.dev operates.
What Lime.dev provides
Lime.dev is SaaS infrastructure for hybrid ENS resolution. We use ENS standards to build a system where:
- •Full ENS subnames are issued offchain
- •Records are updated via signatures (EIP-712)
- •Replay attacks are prevented via nonce
- •Signature expiry is controlled via timestamp
- •Resolution via CCIP-Read (EIP-3668)
- •Optional onchain record publishing
This enables:
- ✓ Instant, gas-free ENS-compatible Web3 identity issuance
- ✓ Mass issuance, gas-free updates
- ✓ Deterministic ownership verification
- ✓ Full ENS compatibility
Web3 identity infrastructure for companies
Beyond the free service for users, Lime targets Web3 companies. We provide SaaS infrastructure with API access that enables:
- •Namespace management
- •Automated subname issuance
- •Mass identity creation
- •Identity lifecycle management
- •Zero-gas onboarding
- •Protection against address spoofing
Especially relevant for:
- •Web3 startups
- •L2 networks
- •Exchanges
- •Wallet providers
- •NFT platforms
- •DAOs
Companies can issue Web3 identities directly to users—no need for users to register ENS names themselves. This reduces friction and eliminates gas costs.
For Teams & BusinessesENS, traditional domains & light-by-default
ENS and traditional domains
Lime supports hybrid resolution for both ENS first-level names (e.g. name.eth) and traditional domains (e.g. lime.dev), using them as ENS-compatible identity namespaces. For traditional domains, Lime leverages the ENS DNS Registrar—allowing existing Web2 domains to be used as ENS-compatible namespaces and to issue subnames under them.
- ✓ Use existing brand domain
- ✓ Issue sub-identities
- ✓ Provide ENS-compatible Web3 names
- ✓ Manage offchain at scale
Light by default, permanent when needed
Identities start lightweight: offchain storage, gasless updates, instant acquisition. When needed, they can be migrated to permanent onchain records. Two-stage model: free frictionless onboarding, optional onchain fixation. This balances scalability and decentralization.
Lime.dev builds on the Ethereum Name Service (ENS) protocol. We issue free ENS-compatible subnames under lime.dev. Our hybrid resolver combines onchain and offchain data via CCIP-Read (EIP-3668). Offchain updates require no gas—only EIP-712 signature. Onchain writes are optional and permanent.
