What you can do
Your handle is the starting point. Here's everything you can do with it — use as much or as little as you like.
Receive on any chain
Point @you at your addresses on X1, Solana, Ethereum, and Bitcoin. When someone sends to @you, their wallet looks up the correct address for the chain they're paying from — no more copy-pasting a raw base58 string (the long run of letters and numbers a wallet address is made of, e.g. 7Np1jK…pQ4mZ). You hand out one name; it works everywhere you hold funds.
Your home chain. @you resolves to your X1 address so anyone can pay you on X1 by name.
Add your Solana address and receive there too. On X1 and Solana the same wallet key works, so this usually needs no new setup.
Add your Ethereum address so people on Ethereum can send to @you instead of a 0x… string.
Add your Bitcoin address and collect BTC under the same handle as everything else.
You choose which chains to add — one or all four. Add more later at any time; your handle stays the same.
Get paid with a QR code and a link
Every handle 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 apps that support X1ID display your wallet as @you instead of a long address — in transaction histories, profiles, and anywhere your wallet appears. It's the difference between being 7Np1jK…pQ4mZ and being a name people recognize.
Build a web3 profile
Behind your handle sits a profile you control:
Avatar & display
A picture and details that make @you recognizable at a glance.
Website & socials
Link your site and social accounts so people can find the real you.
Decentralized site
Attach a link to your decentralized website, tied to your handle.
All in one place
Everything lives under @you, so your identity travels with your name.
Subnames
One handle can branch into purpose-built names — pay.you, docs.you, shop.you — all under the handle you already own, at no extra registration fee. Each one can carry its own addresses, so you can keep your money and your projects neatly separated under a single identity.
Subnames go a second level deep, too: pay.you can have its own deep.pay.you sub-subname, for whoever needs to split a subname further (a payments subname handing out per-client or per-project addresses, say) without touching the parent handle.
Separate your money
Give out pay.you for payments and keep @you for your identity, so a public payment name never exposes your main wallet.
Organize a project
docs.you, app.you, shop.you — 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 claim to be @you. Verification lets you prove it — two ways:
Verified addresses
Prove you control each address on your handle and it shows as verified. Senders can tell a confirmed address from an unproven one before they send a single coin.
Prove you own @you
Any app can challenge you to prove ownership of your handle with one signature — the registry is the source of truth, so a copycat can't fake it. Try the live proof demo in the app under Verify.
Verified records are the ones others should trust. An unverified address is shown as unverified so no one mistakes an unproven claim for a confirmed one — honesty is built in, not bolted on.
Own it permanently
Register a handle the standard way — the default — and it's yours to keep for a single, one-time payment. 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.
Or lease-to-own it. At registration you can instead pay a fraction of the price up front — about a quarter, by default — and build equity toward that same permanent price over time. Pay it off in full at any point and it converts to permanent immediately, no more payments. Miss a payment and you still have a 30-day grace period before the handle becomes reclaimable — the same anti-inaction protection standard registration is built on, just with a lower bar to get started. See the FAQ for the mechanics.
A safety net
Losing access to a wallet is the nightmare scenario in crypto. X1ID gives you two tools for it:
Gift a handle
You can pre-pay a handle for someone else — a great way to bring a friend onto X1. You cover the registration price up front; when they claim, the expensive part is already paid, and all they need is a tiny amount of XNT for the claim transaction's fee and the handle account's rent (unless someone relays the claim for them).
Pick a name and pre-pay it
Choose the handle you want to give and pay its registration fee up front. The amount is set aside for that specific name.
Send the gift
Send it to a friend to claim. You can tie the gift to a specific wallet so the handle lands there no matter who opens it.
They claim it — registration prepaid
Your friend claims the handle without paying any registration fee — just the transaction fee and account rent, a tiny amount of XNT. It becomes theirs, fully owned, from that moment.
A gift is set aside for the name you chose, and it has an expiry of at most 366 days. If it's never claimed, the amount you pre-paid comes back to you — you're not out anything for an unclaimed gift.
Send XNT by email
Send XNT to someone who's never used crypto — no wallet address, no app, no seed phrase. Enter their email and an amount; we set up their x1id wallet, you send to it from your own wallet, and they sign in at app.x1id.io with that email to find the funds already there.
Enter an email and an amount
On the Send page, type the recipient's email and how much XNT to send. We pregenerate their x1id wallet for that email (or reuse it if they already have one).
Send from your own wallet
Your wallet signs a normal transfer to that address — X1ID never holds the funds. No escrow, no claim link.
They sign in and it's there
Whenever the recipient signs in at app.x1id.io with that email, their wallet appears automatically with the XNT already in it — a non-custodial wallet in their own name, no claim transaction needed.
Because the recipient never submits a transaction to receive, this works even for a brand-new wallet with no XNT of its own — it costs the recipient 0 XNT to receive, so the "empty wallet can't pay its own fee" problem simply doesn't arise.
Treat it like any crypto transfer. The send is a real, non-custodial, on-chain transfer to a real address — there's no escrow, no claim link, and no way to reverse it. The email controls a genuine wallet holding genuine funds, so double-check the address you're sending to exactly as you would for any crypto payment.
Buy and sell handles
X1ID has a built-in marketplace at app.x1id.io/marketplace — no third-party site needed. Handles change hands right inside X1ID, so a sale is as safe and final as any on-chain payment.
Registrations and marketplace actions may be paused. The registry has an emergency lockdown, used for example during a security audit. While it's on, the program rejects new registrations, NFT mints, reserved-name and gift claims, TLD creation, and new listings, offers and auctions (ProtocolLockedDown / MarketPaused). Resolution, transfers, set_primary and records keep working, as do exits such as cancelling a listing, completing an existing sale, and lease renewal. Check the banner on app.x1id.io, or read the flag from the Config account with the SDK's readPauseState.
List a handle you own at a fixed price. When someone buys it, it's theirs and the proceeds come to you, minus the fee. A tokenized handle (the default) changes hands as an NFT transfer; a name-only handle transfers directly within X1ID. While a tokenized handle is listed, its NFT is frozen — you can't send it to someone else until you cancel the listing first.
Buy a listed handle outright at its asking price and it's yours immediately — the perfect way to get a name someone else already registered. Select several listings at once and buy them all in a single transaction and signature; if one has changed or sold since you selected it, that row is dropped and named before you sign, and the rest still go through.
Make an offer on a handle that isn't a capability NFT — a name-only handle (lease-to-own), a plain un-minted registration, or a treasury-held name. The owner can accept whenever they like; your offer is held safely until then. Offers (and auctions) are not available on tokenized handles — the default for a standard registration — which sell only by fixed-price listing or by a direct NFT transfer.
Bid in an auction for a sought-after name (a name-only or treasury-held name — auctions, like offers, don't apply to tokenized handles). The rules the program enforces: a run lasts between 10 minutes and 30 days; each bid must clear the reserve and beat the current high bid by at least 5%; the seller can't bid on their own auction; and once it has bids it can't be cancelled, and the name can't be transferred, released or recovered until the auction settles (likewise, no bid lands while a recovery is pending). If the seller no longer owns the name (it was transferred, released or tokenized), anyone can close that seller's stale auction as long as it has no bids; the rent goes back to the seller. Anti-sniping: a bid in the final 5 minutes pushes the end out to 5 minutes from that bid (end = max(end, now + 5 min)), so a last-second snipe can't win uncontested.
Premium and reserved names — short names, brands, and well-known words — are released through the marketplace rather than by ordinary registration. A 2% marketplace fee applies to name-only sales; a tokenized handle carries a 2.5% on-chain royalty instead (it replaces the fee). Details are on Fees.
Your handle is a tradeable NFT — a standard registration includes it, minted in the same transaction — so you can sell it on the X1ID marketplace or on standard Solana NFT marketplaces (it's Metaplex-compatible), with nothing extra to do. One thing to know: while a handle is listed on the X1ID marketplace its NFT is frozen, so cancel the listing before sending or re-listing it elsewhere. Name-only handles (from lease-to-own) trade on the X1ID marketplace and can be minted into an NFT anytime. See the FAQ.
