What you can do
Multi-chain address records, a primary name, a profile, subnames, verified records, permanent ownership, recovery and locks, agent records — everything an ArcNS name gives you, and what is not live yet.
Your name is the starting point. Here's everything you can do with it — use as much or as little as you like. Two features the app is built for are not live yet on Arc testnet and are marked as such below, so nothing on this page is a promise dressed up as a fact.
Receive on any chain
Point @you at your addresses on Arc, Ethereum, Bitcoin and Solana. Each is a separate address record with its own ENSIP-11 coin type and its own verification flag. When someone sends to @you, a name-aware wallet reads the record for the chain they're paying from — no more copy-pasting a raw 0x… string. You hand out one name; it works everywhere you hold funds.
Your home chain (coin type 2152525650). @you resolves to your Arc address so anyone can pay you on Arc by name — this is the record the payment QR and link use.
You choose which chains to add — one or all four. Add more later at any time; your name stays the same. A chain with no record answers an explicit no-record-for-chain, never the wrong address on the wrong chain.
Get paid with a QR code and a link
Every name with an Arc record comes with a QR code and a shareable payment link, so people can pay @you by scanning or tapping instead of copying an address. Show the QR in person, or drop the link in a bio, a message, or an invoice.
Be shown as @you everywhere
Set @you as your primary name and explorers and apps that integrate ArcNS display your wallet as @you instead of a long address — in transaction histories, profiles, and anywhere your wallet appears. There is exactly one primary per address across all three namespaces, and it is shown only while it forward-confirms: a @handle primary must still be owned by the address, a .arc / .circle primary must still resolve back to it. A stale primary is never shown.
Build a profile
Behind your name sit text records you control — the same ENSIP-5 records ENS-aware wallets already read:
Avatar & description
A picture and a line of text that make @you recognizable at a glance.
Website & socials
Link your site and social accounts so people can find the real you.
Agent records
agent.manifest, agent.x402, agent.mcp, agent.a2a, agent.erc8004 — the endpoints and identity of an agent, on its name. See below.
All in one place
Everything lives under @you, so your identity travels with your name — and is cleared automatically when the name changes hands.
Subnames
One name can branch into purpose-built names — pay.you.arc, docs.you.arc, shop.you.arc — all under the name you already own, at no extra registration fee. A @handle gets sub-handles the same way (pay.@you). Each one can carry its own records, so you can keep your money and your projects neatly separated under a single identity.
Separate your money
Give out pay.you.arc for payments and keep you.arc for your identity, so a public payment name never exposes your main wallet.
Organize a project
docs.you.arc, app.you.arc, shop.you.arc — one name per purpose, all clearly yours.
Onboard a team
Hand teammates or departments their own subname without giving up control of the parent.
Prove it's really you
Anyone can set an address on a name. Verification lets you prove it: for each record, prove control of that address for that chain and it shows as verified. Senders can tell a proven record from an unproven one before they send a single coin.
Verified records
A signature from the address (or an on-chain call for a contract wallet) on a challenge bound to your name's current version. Any later change to the record clears the flag.
Honest by default
An unverified record is shown as unverified so no one mistakes an unproven claim for a confirmed one — the API, the SDK and the app all carry the flag.
Verified records are the ones others should trust. The full mechanics — the challenge format and what each proof type checks — are on Verified records. Signing in to third-party apps with a name is not a feature ArcNS offers today.
Own it permanently
You register a name once and it's yours to keep. There's no renewal to remember and no expiry date that could hand your name to a stranger. This is a deliberate choice: a name people send money to must never quietly change owners because a payment was missed. See Fees for how one-time pricing works.
A safety net
Losing access to a wallet is the nightmare scenario in crypto. A @handle gives you two on-chain tools for it:
.arc and .circle names use the verbatim ENS registrar, which has no recovery or lock: protect the wallet that owns them, or hold them from a smart-contract wallet with its own recovery.
Agents
An ArcNS name is the naming layer Arc's agent stack lacks: ERC-8004 gives an agent a numeric id, ArcNS gives it @payday-bot. A name carries the agent's endpoints and identity as text records (agent.manifest, agent.x402, agent.mcp, agent.a2a, agent.erc8004), while the payment address stays the on-chain Arc record with its verified flag — the one pay-to fact that is proved rather than asserted.
MCP server
Resolve names, check availability, read agent records and prepare registrations from Claude Code, Cursor or VS Code — no key, no auth for reads.
Pay per read with x402
Agents read the resolver API for $0.001 a call, settled in USDC from a Circle Gateway balance — no gas, no key.
Register without a wallet on Arc
POST /raas/register: pay once over x402 and receive the name minted to your own address in about two minutes.
The Agent handle type exists on chain and the API and SDK report it (handleType), but the app does not offer it at registration yet. An agent name is recognised by its records (agent.manifest / agent.erc8004) as well as by its type — see the verification ladder on the MCP page.
Not live yet
Two features the app is built around are switched off in the app today, even though their contracts are already deployed on Arc testnet. They are listed here so the docs never describe something you cannot do today.
