·One signature. No password. No email.

How it works

From wallet address to @yourname in about 30 seconds.

Pick a name

Type the @name you want. Live availability checks tell you instantly if it’s free, with smart suggestions when it isn’t.

Sign once

A single message signature proves the wallet is yours. No transaction. No gas. No password to forget later.

Get paid

Share paytag.io/yourname. Anyone can send you crypto with one link — no install, no extension, no copy-paste.

For developers

Resolve a name. One call.

A predictable JSON API with stable error codes and a 30-second edge cache. Drop it into a wallet, payment app, or invoice tool — anywhere a wallet address would otherwise be.

Why paytag

Designed to disappear behind the experience.

@01

One name across chains

Map @yourname to your Ethereum, Solana, and Bitcoin wallets. Senders pick the chain — you keep one identity.

@02

No custody, no keys held

Paytag never touches your private keys. Authentication is a single message signature; payments stay in your wallet.

@03

Built for builders

A clean JSON resolver behind a stable contract. Drop it into wallets, payment flows, or invoice tools in minutes.
