Gapline judge walkthrough

The working core

Monitor NVDA, TSLA, AAPL and SPY bStock markets, value manually entered holdings and save your portfolio privately. Quotes and signing permissions remain separate.

1. Open the product and add a small manual NVDA holding. This tracks an existing holding; it does not buy stock.
2. Open Gap Monitor. Inspect the source label, current price and reference provenance. Live public prices are not executable quotes.
3. Sign up to save privately, refresh and confirm the holding remains.
4. Open Wallets to connect a browser BSC wallet or inspect the separate private Guardian preparation path.
5. For a real mainnet demonstration, attach a genuinely completed bStock transaction and verify its receipt below.

What is verified—and what is not

• bStocks is central: NVDAB, TSLAB, AAPLB and SPYB on BSC.
• Public market prices and persisted observations are live; the signed Web3 API can return a compliance restriction.
• The current fallback reference is a Friday UTC token-market close, not the underlying stock's Friday New York close. This is a token-market change monitor, not a verified TradFi arbitrage signal.
• The local Binance Agentic Wallet service obtained a real 1-USDT bStock quote. A quote is not a trade or a transaction simulation.
• Trading, Guardian automation, gifts, salary allocation and vault rebalances are not live. Money screens save plans only.
• Ondo/xStocks are not verified live integrations. Agent Studio is optional and not integrated.

Verify a bStock transaction

No transaction is attached to this submission yet. A quote or local-chain test does not replace a live BSC-mainnet demonstration.

Submission checklist

Do not mark the entry fully compliant until the real mainnet demonstration, required API evidence, your personally written developer-experience report and submission are complete.

• Public source repository
• Judge instructions and implementation evidence
• Questions for the developer's own report
• Official project submission
• Official developer-experience report form

Submission lock: October 11, 2026, 12:00 UTC / 13:00 Lagos. A video of four minutes or less is recommended, not mandatory. Verify eligibility personally before submitting.
