The naming layer for the Sui economy.
From simple .sui domains to a rich identity, social, and discovery protocol — and the $NS token that powers it.
Why SuiNS — the default identity layer of Sui
A blockchain wants exactly one answer to “who is alex.sui?”. Built by Mysten — the same team behind Sui and the Slush wallet — SuiNS is the default wherever users already are, with no clash between the protocol and the wallet. Once a naming service is everywhere and most users hold a name, network effects lock it in: more names make it more worth integrating, and more apps make every name more useful. That is how a naming service becomes a monopoly — and SuiNS owns the .sui suffix itself. It is becoming the identity and social layer of the whole chain, not just a place to register domains.
The flywheel is about to turn
The triggers are arriving now. Sui already has free peer-to-peer transfers, and Hashi lets holders post native Bitcoin as collateral to borrow stablecoins — pulling dormant BTC and fresh stablecoin liquidity onto the cheapest money rail on earth. When people pay each other every day, they need a handle to be paid — you cannot send money to a 64-character address. That demand shows up as .sui registrations and renewals, which are what generate SuiNS protocol fees. 80% of every fee buys back and burns $NS; the rest funds the DAO treasury. More users → more names → more fees → a scarcer token.
Three sources of unstoppable demand for names
Payments
Free P2P transfers, plus Hashi unlocking native BTC as collateral to borrow stablecoins, pull real money onto Sui. You cannot send money to a 64-character address — so people register a name to be found and paid. Each new payer is a new name, and names are what SuiNS charges for.
Websites
A .sui name is the human-readable URL for a Walrus Site — a fully decentralized website whose files live on Walrus storage and whose ownership lives on Sui. Buy a name, link it, and your site is live at name.wal.app. No host, no server, nothing to take down.
Build with AI → WAL-0Agents
As AI agents get their own on-chain wallets and pay each other in stablecoins (x402, ERC-8004), every agent needs a discoverable, human-readable identity. The agent economy is a naming land-grab — millions of named, addressable, payable agents.
- ◆Free P2P transfers — Sui is the only chain where sending is free; value drifts to the cheapest rail.
- ◆Securely borrow stablecoins against native Bitcoin.
- ◆Websites: every .sui name is a decentralized Walrus Site URL (name.wal.app).
- ◆Agents: the AI agent economy needs millions of named, payable identities.
- ◆Payments need human-readable addresses — driving organic demand for names.
- ◆Built by Mysten and owner of the .sui suffix — the default names of Sui.
- ◆Network effects: integrated everywhere, held by everyone — a naming monopoly.
- ◆Deflationary by design — 80% of protocol fees are burned, sending the Sui System account rising in the $NS holder ranks.
- ◆A clear path from on-chain names to global DNS (.sui at ICANN).
What is SuiNS?
The Sui Name Service (SuiNS) is a distributed, open, and extensible naming system on the Sui blockchain. It maps human-readable names like alex.sui to machine-readable identifiers such as Sui addresses, IPFS content hashes, and other metadata.
Simplified Payments

Digital Identity
Use your .sui name across the metaverse and DeFi protocols.
Decentralized Profiles
Link avatars, socials, and bios to your name.
