Search without connecting
Look up a public Fast ID by its given.family name or by its Fast address. Public profiles and their evidence can be read without a wallet.
How Fast ID works
Fast ID gives a Fast address a memorable public name and profile. It helps people connect an address to public evidence, but it does not automatically prove that the address belongs to a particular legal person.
The process
From a Fast address to a public Fast ID
- 1
Connect your address
Choose Fast App or Fast Wallet Extension and select the address that will own the name.
- 2
Choose a name
Search for a canonical given.family name. The availability check is helpful, but the settled Fast claim is authoritative.
- 3
Review and claim
Confirm the name, public URL, signing address, network, permanence notice, and any fee. Your wallet then signs the claim.
- 4
Use the public page
After settlement and registration, the name resolves to the address. You can add a profile, share the page, and show supported evidence.

What you can do today
Connect in two ways
Use Fast App or Fast Wallet Extension. Fast App users can switch addresses from the header, and disconnecting clears the saved connection before the next connection.
Claim a public name
Choose an available given.family name, review the exact address, network, public page, and any network fee, then approve the claim in your wallet.
Create a simple profile
Add a display name, bio, and avatar. Profile changes are authorized with the wallet that controls the address.
Read evidence without a generic badge
A public page separates property control, address signatures, imported claims, and self-reported profile information. Each item says what it proves and what it does not.
Share and reuse the identity
Share the public profile link. The connected owner can also copy social, email, and website-badge snippets. Compact and full JSON identity documents are available for other apps.

What a Fast ID is
- Is it an account?
- No. The Fast address is the account and signing key. Fast ID is the public name, profile, and evidence connected to that address.
- Can one address have several Fast IDs?
- Not today. On a network, one Fast address can hold one active Fast ID name, and one name can be held by one address at a time.
- What if a person has several addresses?
- Fast ID does not assume those addresses belong to the same person. They remain separate until an explicit, verifiable multi-address or address-rotation flow is added.
- Can a name be changed or transferred?
- The current web app has no direct transfer control. The model is release and later reclaim, with the old record kept permanently so history is not rewritten.
The important boundary
What the evidence means
- Name bindingA settled Fast claim connects the name to the signing address.
- Control provenA website or supported account proof shows control of that property—not legal identity.
- Signature provenA Fast address signed the shown bytes—not automatically that it authored them.
- Self-asserted or self-reportedImported work, display name, and bio are claims from the address, not independent verification.

Coming next
These are the next capabilities in the current product and architecture plan.
Self-service proof management
Add, refresh, and remove website and GitHub control proofs from the web app, and manage imported academic work without an operator-assisted flow.
Complete name and address lifecycle
Add clear controls for releasing a name, reclaiming it later, and moving to a new address while keeping the historical record understandable. Direct transfer is not the model.
Historical checks inside Fast Sign
Fast Sign will be able to check whether an address was bound to a Fast ID when a document attestation settled, including honest pending and indeterminate results.
More evidence and credentials
Later versions can add more social-account proofs, issuer credentials, organization roles, and delegated signing relationships without treating every proof as legal identity.
