Check ID: ownership-pseudonym Claim a portable handle with a wallet signature. A public name, not a legal identity.

Use cases

Instant. The user signs once and the pseudonym binding is created.

Field	Required	Notes
`pseudonymId`	Yes	Handle, 3–32 chars, pattern `^[a-z0-9][a-z0-9._-]{1,30}[a-z0-9]$`
`namespace`	No	Defaults to `neus`
`displayName`	No	Human-readable label
`metadata`	No	Optional object for app-specific attributes

{
  "pseudonymId": "alice123",
  "displayName": "Alice"
}

Pseudonym proofs are time-bound: the receipt includes an expiresAt. Re-verify to refresh before it lapses. Full schema: ownership-pseudonym.json.
