About three minutes. Generate a fresh nym, save its 12 words, describe your character, and sign one avatar request. Your secret key stays in this browser.

Before you start · protect your key

The nihao generator creates a fresh key locally in this tab. The key and its 12 words never leave your browser; we cannot see, store, or recover them. Write the words down before registering.

Never paste a personal or existing account key here. This nym is isolated to this demo street and is only for your Street of SEC character.

Create your request

This is the only place this key exists. It never leaves your browser and we cannot recover it. Copy the words, download the key file, or write them on paper — then guard them like money. The nsec and the key file are secrets: import them only into a signer you trust and delete the file afterwards. The SEC experts on site can help you set up a proper backup.

2–32 letters or numbers; spaces, hyphens, and underscores are allowed. The name must be unique. Optional visual reference for your avatar — a sketch, a photo of a drawing, a moodboard. PNG, JPEG, or WebP up to 2 MB. It travels only in the private request to the avatar pipeline and is never part of the published Nostr event.

The signed public Nostr event contains the character name, dedicated nym pubkey/npub, culture-and-tools text, derived tagline and traits, appearance direction, timestamp, and MIT license. The optional reference image is sent only in the private request to the join API and is not included in the signed event. Do not enter personal information. Using a dedicated nym key reduces cross-linking; it is not a promise of anonymity.

What happens after I send?

The accepted request enters the avatar pipeline for concept and quality review. Paid 3D generation is never automatic. Keep your 12 words safe: your npub is the identity of this character.
