TL;DR

• $20,000 prize pool, funded by BNB Chain and W3W.
• One track: tokenized stock products and agents on BSC.
• Build September 16 to October 11. Winners announced the week of October 26.
• Your developer feedback report is worth 25% of the score.

Friday, 4pm, New York. The closing bell rings and every stock price in the country freezes until Monday. But, onchain, nothing stops. The tokenized version trades straight through the weekend, priced off a reference that hasn't updated in two days. Anyone can see the gap, and almost nobody has built anything that acts on it.

That's most of this asset class right now. Tokenized equities landed onchain faster than the tooling did, so the agents, baskets, rebalancers and onboarding flows that'll decide how people actually trade them mostly haven't been written yet. Whoever writes them first sets the standard, and the bar is high: tokenized stocks are the first asset class where your onchain product goes head to head with a Web2 product people already use and already like. You're building against a brokerage app that works.

So we're putting $20,000 behind whoever takes it on. BNB Chain and Binance Web3 Wallet are running BNB Hack: Tokenized Stocks Edition, three and a half weeks, one track, and the full stack to do it with.

What to Build

Everything lives under a single track and you can attack it from whatever angle suits you. An autonomous agent, a trading interface, a portfolio tool, a dashboard, a Telegram bot, an MCP server, an SDK. But the rules matter:

• At least one of bStocks, Ondo or xStocks has to be central to what you submit.
• Cross-asset products are in scope, including pairing a tokenized equity leg with crypto or stablecoins.
• Spot only. Perps are out.
• BSC mainnet only. Dry-run with the Transaction API while you build, then demo with small live amounts. Teams fund their own wallets.

Some directions we'd love to see someone take:

• An LLM agent that reads a strategy in plain English, something like "rotate into defensives when volatility spikes", then writes and executes the rules itself.
• Market-hours arbitrage. Tokenized equities trade around the clock while the underlying market's shut, and an agent that prices that gap properly is genuinely new work.
• Cross-protocol arbitrage between the bSTOCKS and Ondo representations of the same underlying.
• Auto-DCA and rebalancing into a tokenized stock basket on a schedule, with drift thresholds.
• An earnings-calendar agent that positions ahead of scheduled events and flattens afterwards.
• A "buy your first stock onchain" flow. Card to tokenized equity in under a minute, no seed phrase in sight.
• One-tap thematic baskets across AI, semis or energy, with transparent onchain composition.
• An MCP server or SDK wrapper that makes the Binance Web3 API one-line callable from any agent framework, or straight from Agent Studio.

Combining API modules in a way that looks like it shouldn't work but does is exactly what we're hoping to see.

The Stack: Binance Web3 API, Agentic Wallet, BNB Agent Studio

Binance Web3 Wallet brings the full surface. The Binance Web3 API is your single point of aggregation across bStocks, Ondo or xStocks, covering market data, quotes, swaps and transaction handling, so you're not writing three integrations to price one underlying. Agentic Wallet and Wallet Skills handle the AI execution layer.

From the BNB Chain side, BNB Agent Studio gives your agent an identity, an autonomous runtime and self-funding via x402, which is what turns a script into something that stays alive without you babysitting it.

Simply register for the API service using a Binance account or an external wallet address to get free API access for the whole hackathon, and winners keep elevated rate limits afterwards. 

What to Submit

Both are mandatory. Miss either one and you don't get scored.

Your project

A public repo, a demo video of four minutes or less, and a deployed link or instructions someone can follow. Judges need to run it. If they can't, you're scored on the video alone. Already have a product? You can enter a new integration into it, with a before and after.

A Developer Experience Report

Most hackathons don't ask for one. This one does, and it's worth a quarter of your score.

We want to know how long it took from opening the docs to your first successful API call, and where you got stuck. Which page had the error, and where on it. Which error messages made no sense, which edge cases bit you, what the latency looked like. How the assets actually behaved: liquidity depth, slippage, what happens outside traditional market hours, how the bStocks, Ondo or xStocks versions of the same thing differ in practice. And the one we care about most: if you were the engineer behind the developer platform, how would you rebuild it so someone can make a call the moment they land?

Specific and honest beats polite. Vague feedback doesn't count, and perfunctory or AI-generated reports won't be accepted. AI-assisted code is fine.

How It’s Scored

Scores get pooled after each judge has worked through every project on their own.

• Technical implementation, 30%. Does it run, and how deep does the integration go? Modules used, error handling, how it holds up.
• Creativity and originality, 25%. Were the APIs used in ways nobody expected? Does this already exist five times over?
• Developer Experience Report, 25%. Specific, actionable, honest, no fluff. Includes the AI stack section.
• Product quality and UX, 20%. Is it usable by the people it's for? Would it bring non-crypto-native users onchain?

There's no live PnL scoring. Doing it fairly over one week would need a slippage model, standardised capital, held-out snapshots and wash-trading review, which is more ops than the signal's worth.

Screening comes first, on completeness and eligibility. Tie-breaks go on depth of W3W API usage first, then the quality of your feedback report.

Prizes

Main placements:

• 1st: $6,000
• 2nd: $4,000
• 3rd: $3,000

• 5th: $1,000

Two stack specials at $2,000 each, awarded across every submission with no separate entry needed. You can win a main placement and a special:

• Best Use of Agentic Wallet / Wallet Skills - funded by Binance Web3 Wallet. Deepest, most credible use of the AI execution layer.
• Best Use of BNB Agent Studio - funded by BNB Chain. Deepest use of BNB Agent Studio: agent identity, autonomous runtime, self-funding via x402.

On top of the cash, enjoy free API access during the event and elevated limits afterwards if you win, a mentor for every finalist team from across both partners, eligibility for the BNB Chain Kickstart Package if you place near the top, and winner spotlights on X and bnbchain.org.
