What Nina does

• Answers crypto-market questions — prices, sentiment, fund flows, on-chain data, project background; answers what you asked, conclusion first.
• Predicts sports and markets — World Cup and other sports events plus crypto markets; predict alongside Nina and share the result.
• Trades in-product, non-custodially — token swaps, Polymarket predictions, and Hyperliquid perpetuals, each signed by you.
• Produces structured analysis reports — fixed, visualized frameworks via Skills.
• Plugs into your workflow — pipe Nina’s data and analysis into the tools you already use via MCP.

Nina vs generic chatbots

What Nina is not

Nina does not custody your funds, trade on your behalf, or take a cut of your principal or profits (only a transparent routing fee on execution), and has zero conflict with exchanges (CEXs). She’s a non-custodial AI assistant — she has a built-in wallet and trading, but your assets and private keys always stay in your own hands, and every transaction is signed by you.

Who Nina is for

Crypto users, active investors, and anyone who wants to decide faster and with more evidence. Whether you’re reading BTC/ETH sentiment, predicting the odds of a World Cup match, or trying to understand a crypto project fast — Nina gives you a structured, data-backed answer rather than vague prose.

Real-time, accurate, unique data

Nina runs on institutional-grade real-time data (via Antalpha), not second-hand data stitched from public APIs. A meaningful share of Nina’s data comes from unique sources others can’t access. For crypto users, that means the sentiment, fund-flow, and on-chain signals you get are timelier and more trustworthy.

Conclusion-first, visualized output

Generic chatbots hand you a wall of text and make you find the point. Nina uses fixed analysis-report frameworks (Skills): conclusion first, then evidence, with charts. Ask A and you get A. This is the biggest felt difference between Nina and generic AI.

Predictions you can co-play and share

Nina is a prediction product. She doesn’t just give you a prediction — she lets you predict together with her, add your own judgment, and generate a shareable prediction card. You move from passively receiving a conclusion to co-deciding with Nina — an interaction generic AI doesn’t offer.

Zero conflict with exchanges; never touches your money

Nina doesn’t custody funds or operate your accounts — your assets always stay in your own wallets and exchanges, and every trade is signed and authorized by you. She isn’t another wallet or exchange that holds your funds; she’s your crypto-intelligence officer and a neutral routing layer that aggregates multiple venues, compares prices, and finds the best route. To execute, you can place an order in one tap right in the Nina app/web, or connect your own tools and exchanges via MCP; both paths are fully non-custodial, and Nina only charges a transparent routing fee on the execution path — never handling your principal.

Sign-up steps

1. Open Nina (antalpha.com, or download the ‘Antalpha AI’ app on Google Play / App Store).
2. Choose a sign-in method (Email / Google / Apple on iOS) to register.
3. If invite-only, enter your invite code.
4. You’re ready to ask Nina your first question.

Supported languages

Nina’s interface and content support five languages: Traditional Chinese, Simplified Chinese, English, Japanese, and Korean.

Ask Nina your first question

The fastest way to get Nina is to simply ask her a crypto question you actually care about.

Try these questions

• “Analyze BTC’s current market sentiment — should I chase it?”
• “How are ETH’s recent on-chain fund flows? Is smart money buying or selling?”
• “World Cup quarterfinals: Argentina vs France, who has better odds? Let’s predict together.”
• “Compare the on-chain data and recent performance of these three coins in one table.”
• “Explain quickly what this project does, who backed it, and what the risks are.”

What you get

Nina won’t hand you vague prose. She will:

1. Lead with the conclusion — answer what you actually asked.
2. Back it with evidence — data, on-chain metrics, sources.
3. Visualize — key points in tables or charts.
4. Offer follow-ups — related questions and directions to go deeper.

How to ask better

• Name the asset and timeframe — “BTC over the last 7 days” beats “how’s BTC.”
• Ask for comparisons directly — request a table, a ranking, or a what-if.
• Want a full report? Invoke a Skill for fixed-framework deep analysis.
• Want to predict? See “Sports & Market Predictions.”

Interface tour

Nina’s main areas:

Suggested path for new users: ask your first question → try a prediction → share a prediction card.

How it works

Just type your question in the chat box. Nina will:

1. Understand your intent — whether you’re asking about prices, on-chain data, a project, or a prediction.
2. Fetch data automatically — pulling relevant data from institutional-grade real-time sources.
3. Output to a framework — invoking a Skill when needed to produce a structured, visualized report.

Questions Nina is good at

• Market & sentiment: BTC/ETH price action, Fear & Greed, social sentiment, KOL moves.
• On-chain analysis: Smart Money flows, whale positions, DEX volume, TVL changes.
• Project research: Token fundamentals, funding background, team, competitive landscape.
• Predictions: match win probabilities, market direction, and crypto-market predictions (all tradable).
• Open-ended: Any crypto question you have — Nina will do her best.

Answer principles

1. Answers what you asked: Focused on your question — no deflection, no non-answers.
2. Conclusion first: The most important conclusion comes first so you can decide fast.
3. Sources & data: Every conclusion is backed by data with transparent sourcing.
4. Extensible: After each answer, Nina suggests directions to dig deeper.

Tips

• Name the asset and timeframe for sharper answers.
• For a full deep report, invoke a Skill.
• Models/Skills depth differs by plan — see “Subscription & Rewards.”

Why you need a sentinel

• Opportunity doesn’t wait — prediction-market odds, match status, and news shift around the clock; you can’t stare at a screen all day.
• Seeing it isn’t understanding it — a plain price alert only says “it moved,” not “why, and whether it matters.”
• Information is scattered — matches, news, on-chain and market data live in different places, and looking them up on the spot is already a step behind.

How a sentinel works

1. Deploy — pick the prediction event or asset to watch and turn on a sentinel in one tap; it starts watching within seconds, no setup.
2. Watch — the sentinel monitors probability shifts, key levels, and related news 24/7, with no need to keep the app open.
3. Explain — on a key change, Nina cross-checks news, match status, and major events to reconstruct what happened and why.
4. Notify— she pushes “change + reason + impact” to you, and reminds you again at milestones (24H and 2H before an event ends, and when it closes).

What a sentinel does for you

Typical watches

For now sentinels focus on prediction markets — e.g. odds on major matches, political and event-driven predictions, and popular crypto-related predictions. Set the events you care about and leave the rest to the sentinel: it stays up so you can step in only at the decisive moment.

How to try it

Update the app to V1.1. The Sentinel entry is right on the home screen — set your first sentinel and let Nina take the watch.

For now sentinels focus on prediction markets (BETA); more domains are on the way.

Live Skills

What she can predict

• Sports — win odds and score leanings for events like the World Cup.
• Crypto markets — price direction, event outcomes, and other market-type predictions (Polymarket, live and tradable).

Trade predictions on Polymarket 【App+Web】

When you like an outcome, you can back it directly: on first use, activate a prediction account with one tap (handled gas-free by the Polymarket relayer — you sign a single authorization), then buy and sell event shares, sell after fills, and redeem after settlement. It’s fully non-custodial, signed by you, and settled on Polygon.

Depending on your region’s regulations, prediction-market orders may be unavailable in some regions (e.g. mainland China); market data and Nina analysis remain fully accessible.

How to use

1. Pick a topic in chat or the predictions entry (e.g. a specific World Cup match).
2. Nina gives her prediction and the basis for it (data, odds, sentiment).
3. View it as-is, or predict together with Nina.
4. Generate a shareable prediction card.

Predict together with Nina (co-play)

1. On a match/market page, tap ‘Predict together with Nina’.
2. Enter your judgment or choice (your lean, your confidence).
3. Submit; Nina combines her data with your input to generate a prediction card.
4. Download or share the card, and invite friends to view and predict too.

Why it’s fun

You move from passively receiving a conclusion to co-deciding; the card is shareable so friends can join; predict together before the match and watch the result together after — a return-visit loop.

Match notifications

Turn on match notifications and Nina will remind you before matches you follow, then send a recap plus the next match afterward, so you never miss out.

The card includes

• The prediction topic (match/market)
• Nina’s judgment and yours
• Visual design (with Nina’s character)

Ways to share

• Download — save as an image and post anywhere.

Why it’s useful

Share your prediction and friends can tap in to predict alongside you. Pair it with an invite code and you can earn referral rewards — turning one prediction into one new user.

What you can see

• Market pulse: BTC/ETH price, Fear & Greed, BTC dominance.
• Cycle position: ahr999, moving-average deviation, RSI, Puell and more — where BTC sits in its cycle.
• Macro backdrop: rates, the dollar, gold and other macro signals at a glance.
• BTC price-distribution forecast: the market’s probability distribution and key percentiles for BTC.

A Nina summary on every block

Each data block carries a Nina read — conclusion first (be optimistic or cautious now), then the key points. Even if the numbers are opaque, the takeaway is instant, and you can “Ask Nina” to go deeper in one tap.

What you can trade

• Token swaps: aggregated quotes across Solana and EVM chains, auto-routed to the best price.
• Polymarket predictions: back an outcome directly — buy/sell event shares and redeem after settlement (settled on Polygon).
• Hyperliquid perpetuals: place and manage on-chain perps (rolling out).

How it works

1. Activate once on first use (e.g. Polymarket is gas-free via a relayer — you sign a single authorization).
2. Nina drafts the transaction and finds the best route; you sign in your own wallet.
3. After it fills you can view, sell, and redeem; your assets and keys always stay with you.

Two ways to use it

• Scheduled reports: describe the analysis you want in plain language, set a frequency (daily/weekly/…), and Nina generates and pushes it on time.
• Price alerts: set a condition on an asset (above/below a price); when it hits, you get notified with Nina’s instant read.

How it differs from Sentinel Mode

Scheduled tasks are your own recurring jobs and price alerts; Sentinel Mode (App) watches the prediction events you follow 24/7 and pings you with the reason the moment something material changes. They’re complementary — use them together.

Integration info

Nina doesn’t custody, trade for you, or take a cut of your funds (only a transparent routing fee on execution). Over MCP, Nina provides data and analysis; order placement and fund operations happen in the tools/exchanges you connect. (To trade directly inside the Antalpha product, see the swap and prediction-trading sections above — also non-custodial and signed by you.)

Who gets access

Lab features are experimental and may change, iterate, or be pulled at any time; they only graduate into the product once stable. Members who stay active and contribute in the community earn early-access eligibility.

US-stock discovery radar

Want to buy US stocks but don’t know where to start? Nina’s quant-signal engine scans the whole pool daily and surfaces opportunities to you:

• Reversal radar — oversold names bottoming and poised to turn up float to the top.
• Coiling detector — names building up for an imminent breakout reach you proactively.
• Fund flows — which sectors and names money is flowing into, so you can follow it.

Single-stock deep dive — analysis to trade

Price momentum, technicals, fund flows, and smart money in one view (Overview / Financials / Valuation / Smart Money / Full chip intel / Events); go deeper anytime with “Ask Nina.”

Tokenized US-stock trading

Connect your wallet and settle with an on-chain signature — fully on-chain, self-custodied (trade tokenized US-stock spot “xStock” via a Solana DEX). Same as crypto and predictions: non-custodial, Nina never touches your money.

This feature is coming soon; actual assets and scope follow the live release.

Subscription plans (coming soon)

Nina’s business model centers on subscription-based intelligence: you pay for Nina’s views, signals, and advanced analysis. On trading, Nina doesn’t custody funds, trade for you, or take a cut of your principal or profits — only a transparent routing fee on execution.

• Free — basic Q&A, try predictions.
• Paid — advanced models, full Skills and deep reports, higher usage limits.

Final plans, pricing, billing cycles, and payment methods are coming soon.

Referral & Invite Codes

Share Nina with an invite code and both you and your friends earn rewards. Get your personal invite code/link, share it with friends — pair it with your prediction card for a stronger hook.

Data types

• Market data — prices, depth, trades, derivatives.
• On-chain data — fund flows, smart money, entity labels, protocol data.
• Sentiment data — Fear & Greed index, social sentiment, prediction markets.
• Security data — address risk, compliance and risk-control signals.

Data providers

Refresh frequency

• Market data/prices/depth, on-chain flow, derivatives: Real-time / on-demand
• Smart Money / Arkham entity snapshot: Continuously updated server-side
• Macroeconomic data (CPI/NFP/Unemployment): Monthly (updated with official release)
• Macroeconomic data (M2/rates/yields): Daily
• Fear & Greed, Social Sentiment: Daily

Why the data is unique

Nina runs on Antalpha’s institutional-grade data flow. Beyond the public data everyone can get, it includes sources ordinary retail users can’t reach — smart-money entity labels, deep derivatives indicators, institutional risk-control signals. That gives Nina an information edge over analysis built on public market data alone.

Institutional-grade data scope

• Asset-class breadth: spot, derivatives, on-chain, macro, sentiment, sports.
• Data depth: down to the L2 order-book level.
• Data coverage across 50+ chains (this is market / on-chain data coverage; swap execution is single-chain — 0x on EVM, Jupiter on Solana — not general cross-chain).
• Data governance: traceable sources, consistent definitions.
• Reliability: 99.9% availability target.

Core design

• LangGraph orchestration: breaks one question into steps — deciding what to fetch first, what to compute next, and when to converge.
• Skills as a framework: each Skill is a reusable analysis workflow, not just a single tool call.
• Skills calling Skills: one Skill can invoke others, composing complex tasks from simpler pieces.
• Conclusion first: you get the judgment and key points first, then the basis and data, then directions to dig deeper.

Why it’s built this way

This structure makes Nina’s answers explainable, reproducible, and extensible — you can see how a conclusion was reached and follow up on it. It also lets capabilities grow like building blocks: add a Skill, gain an analysis capability.

What Nina will never do

• Never custodies your funds — Nina doesn’t hold your assets.
• Never trades for you automatically — every order/transfer is signed by you in-product; keys never leave your wallet.
• Never asks for your private key/seed phrase — any ‘Nina’ that does is fake.

Anti-fraud reminders

• Use Nina only through official links.
• Official staff never DM you first to request sensitive info or transfers.

Your data

Nina stores your conversations and preferences to provide and improve the service. You can request an export or deletion of your data.

Policies

Official Nina staff will never DM you first to ask for your private key or seed phrase, or ask you to transfer funds. Any account that does is an impersonator.

Channels

Security reminder

These are the only official channels. Official staff never DM you first to request your private key or seed phrase, or ask you to transfer funds. Ignore and report any suspicious account.
