01 · The challenge
A trading community needed to admit only members with genuine, active brokerage accounts - manual vetting did not scale and was easy to game.
02 · What I built
A bot that verifies a user's live broker account in real time against the broker's systems and, only on success, issues a single-use, one-time invite to the private community - with no admin involvement.
03 · The hard part
Abuse prevention without standing infrastructure. A lightweight conversational state machine guides each user, duplicate-claim detection is delegated to the broker layer, and every invite is cryptographically unique and expires after a single use - so even a leaked link cannot be reused.
04 · The outcome
Fully automated member onboarding with zero admin effort. Every member is a verified live account holder. Leaked invites are worthless by design.
