The stock sleeps. The token doesn't.
AFTERBELL is a deterministic safety agent for AI agents trading Binance bStocks. It compares the always-open token with the underlying U.S. market and returns the largest defensible order size before execution.
1 · Observe autonomouslyMarket, reference age, liquidity and venue changes are recorded without a request.
2 · Decide deterministicallySeven checks produce a ceiling and a hash-linked receipt. A model cannot raise it.
3 · Hand off safelyPublic tools advise any agent; the demonstrated governed path binds a supported client to a signed authorization.
Why the public result may be $0Public visitors do not provide authenticated account positions. Missing exposure evidence is intentionally blocked, rather than treated as an empty account. The recorded order path below proves a signed authorization was redeemed for 4.86192 USDT—never more than permitted.
