Send money to a name. Not a string you could get wrong forever.
A wallet address is 30-plus random characters. Get even one wrong and the money doesn’t bounce back — it’s just gone, sent to nobody. X1ID gives you a name instead: claim @yournameonce, and anyone can send to it the way they’d send to a Venmo username or an email address.
@handles work today on X1 testnet (an early preview network). X1NS domain names — .x1 / .xnt / .xen — already work on mainnet, the live network.
@jack and jack.x1 can belong to two different people. Watch X1ID refuse to guess which one you meant:
Illustrative — real lookups on X1ID work exactly like this. Try a real lookup.
One registry. Three different reasons to care.
Claim your name in under a minute.
Search @yournameor a domain name and verify you own the wallet — it’s yours right away, for good, priced by length. It’s not just for individuals: merchant and organization handles work the same way, for a business or a group. Transfer it whenever you want, and if you ever lose your key, an optional recovery address can reclaim it after an on-chain waiting period — seven days today, set by the registry — that you can cancel at any time. Attach addresses for X1, Solana, Ethereum and Bitcoin, each one proven on chain; wallets look up the X1 and Solana ones today, and Ethereum and Bitcoin lookups are next on the SDK roadmap.
Search & claim a handleYour name is reserved, not blocked.
19,571 names are held by the registry treasury so a stranger can’t impersonate you. Prove the name is yours — a DNS TXT record on the matching domain for a company; social-account proof for people is coming — and after verification we transfer it to your wallet, free, always. You’re never charged for a name that’s already yours.
Add handle resolution to your app.
Three ways in, same source of truth: the @x1id/resolve SDK (TypeScript, MIT-licensed), a read-only REST API you can self-host, or derive the account and read it yourself in any language. None of them depend on an X1ID server being up.
Check if your name is still there.
Search, verify, and claim a handle on X1 testnet today. Mainnet names are registered fresh at launch — testnet names don’t carry over.
