The Antalpha behind Nina

Behind Nina is Antalpha (NASDAQ: ANTA)— a Singapore-headquartered Bitcoin-mining fintech and a key financial bridge in the Bitmain ecosystem, long providing the world’s miners, mining pools, and mining farms with mining-rig collateral loans, staking loans, and financial derivatives that hedge coin-price risk. Nina is its first public product after entering AI infrastructure.

What Nina can do

Through a single conversation, Nina gets you actionable insight and professional analysis — conclusion first, evidence attached, visualized, then directions to go deeper. No switching between a handful of apps and websites: one chat entry to ask about predictions, check crypto, and watch US stocks, all at once.

Three markets you care about

One chat entry covers all three markets; every trading action is non-custodial and signed by you.

Nina’s four features

• Structured analysis reports: fixed frameworks via Skills output conclusion-first, visualized deep research.
• Sentinel mode: Nina watches the prediction events and assets you follow 24/7 and proactively notifies you — with the reason — the moment something key changes.
• Scheduled tasks: set recurring reports and price alerts; Nina works proactively on your schedule.
• MCP workflow: pipe Nina’s data and analysis into the tools you already use via MCP.

Nina’s five-step flow for one answer

From one plain-language sentence to an actionable brief, Nina runs five internal steps; control of your assets always stops at step 4 — in your own wallet.

Nina’s boundaries

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.

Verifiable & disclaimer

Every Nina conclusion carries source and freshness badges — the Run Card names the specific provider and update cadence, so you can judge at a glance how much to trust it; when data is insufficient, Nina simply says “I don’t know” rather than padding the answer. Everything is for information and analysis purposes and is not investment advice.

Every conclusion names the specific provider and update cadence in the Run Card — how much to trust it, judged at a glance.

Nina for you

Standing in your shoes, understanding your preferences, helping you Understand, Discover, and Explore the investment opportunities of the blockchain world.

Most tools stand on the data side, piling charts and metrics in front of you; Nina stands on your side. She remembers your interaction habits, frequent addresses, and risk preferences — no need to retrain her over and over; the more you ask, the better she knows what you want.

Understand: New to crypto? Ask anything in plain language — what a token is, how a protocol works, what a piece of news means. Nina translates prices, on-chain data, and project background into words you understand — conclusion first, sources you can check.

Discover: Already surfing on-chain? Let Nina watch the market for you — smart-money moves, fund-flow anomalies, social-sentiment turns, prediction-market odds shifts. Turn on Sentinel Mode and scheduled tasks, and key signals come to you with the reason attached, instead of you chasing ten websites.

Explore: Want to turn judgment into action? Nina compares prices, calculates costs, checks risk, and drafts the transaction — from swaps across chains to one-tap prediction-market orders. And the last step is always yours: non-custodial, signed by you. She finds the opportunity; the decision is always your own.

Whether you’re a first-time buyer, a seasoned trader watching the market all day, or a busy person who just wants ten minutes a day to grasp the big picture — Nina works from your side, in your language, at your pace.

Real-time, accurate, unique data

Nina runs on institutional-grade real-time data flows from 9 named data sources — Hyperliquid, Nansen, DeBank, FMP, and more (provided by Antalpha) — with intelligence and data covering 50+ chains, not second-hand data stitched from public APIs. A meaningful share of Nina’s data comes from unique sources others can’t access, not the commodity feeds everyone can look up, and every conclusion tags its source and freshness. 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.

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.

How Nina differs from data tools & general AI

Data tools stop at data, and general AI stops at an answer; Nina joins up the whole loop — intelligence → decision → execution you sign. The differences come down to five points:

• Non-custodial execution loop: from intelligence to a transaction draft to your own signature, the whole loop is closed — data platforms stop at “data,” while Nina carries you all the way to the point where you can sign.
• Proactivity: Sentinel Mode and scheduled tasks watch the market 24/7, and key signals come to you with the reason attached — you don’t have to chase them.
• Memory: she remembers your interaction habits, frequent addresses, and risk preferences, getting to know you the more you use her.
• Publicly-listed backing: built by Antalpha (NASDAQ: ANTA) — a verifiable, real-world signal.
• Transparent & verifiable: every reply carries trust badges and data sources you can check back against.

Sign-up steps

1. Open Nina (antalpha.com, or download the ‘Nina APP’ app on Google Play / App Store).
2. Choose a sign-in method (Email / Google / Apple) to register.
3. 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?”
• “In this prediction event, which outcome has better odds?”
• “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? Go to the Skills directory for fixed-framework deep analysis.
• Want to predict? See “Sports & Market Predictions.”

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

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 — going to the Skills directory 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, go to the Skills directory.
• Models/Skills depth differs by plan — see “Subscription & Rewards.”

A Nina summary card on every page

Each data page carries a Nina summary card — 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 she can predict

• Sports — win odds and score leanings for major matches.
• 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

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.
• Steady trend — names whose structure is still intact get their own list.

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” on Solana, plus US-stock spot and limit orders on Robinhood Chain. Same as crypto and predictions: non-custodial, Nina never touches your money.

Tradable assets and scope vary with local regulation.

US-stock analysis frameworks

Beyond the radar and the single-stock page, Nina has five US-stock analysis frameworks you can call directly: single-stock analysis, the daily US-stock digest, intrinsic-value estimation, quality scoring, and sector overview.

What you can trade

• Token swaps: same-chain swaps across five EVM chains (Ethereum / Base / Arbitrum / Polygon / Optimism) and Solana, with cross-chain routed through LI.FI — auto-compared for the best price.
• Tokenized US stocks (xStock): buy and sell tokenized US-stock spot on Solana and Robinhood Chain, limit orders supported.
• Polymarket predictions: back an outcome directly — buy/sell event shares and redeem after settlement (settled on Polygon).

How it works

Why trading is safe

Safety rests on one rule: analysis in the cloud, signing in your hands. Antalpha only analyzes, finds routes, and drafts transactions; your private key, signatures, and funds stay in your own wallet — only an unsigned draft ever crosses between them, never a key.

Trust boundary: what’s yours vs. what’s in the cloud

Only the unsigned draft flows between them; the signature always happens on your side — that’s what “non-custodial” means.

Lifecycle of a transaction

Control always stops at step 4 in your wallet — nothing runs unless you sign.

Defense in depth

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 key moments as an event nears its close.

What a sentinel does for you

Typical watches

Sentinels currently watch two kinds of target: prediction-market events — odds on major matches, political and event-driven predictions, popular crypto-related predictions — and individual US stocks. Set the events or tickers 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.

Sentinels currently watch prediction-market events and US stocks (BETA); more domains are on the way.

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.

Skill-package panorama (18 skill packages · 120+ tools)

Nina’s capabilities are made up of 18 skill packages and 120+ built-in tools, covering the full path from intelligence to execution:

18 skill packages and 120+ tools, covering the full path from intelligence to execution.

Live skills

The above are the skill packages Nina / MCP has opened up (reconciled with llms.txt §6, 18 skill packages, 120+ tools); the live tools/list is the source of truth for the exact tool inventory. Every trading action is non-custodial and signed by you.

Analysis-report Skills (fixed frameworks)

Beyond single-purpose tools, Nina also turns professional crypto analysis into fixed, repeatable, structured report frameworks, invoked on demand — like giving an analyst a standard operating procedure:

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.

Subscription plans

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.

Subscriptions are currently purchased in the app (iOS App Store / Google Play) across three tiers — Free, Pro, and Elite — with a 7-day free trial for eligible new subscribers. Prices are shown by the store for your region; web plans are still to be announced.

Referrals & points

Share Nina with your personal invite code and both you and your friends earn points (⬡). Once a friend signs up and activates, you and your friend each receive 100 points. Points are platform activity reward credits and may be used for membership benefits, cash and other reward activities; what each activity actually offers takes precedence.

Activation must be completed within 7 days of sign-up: at least 3 conversations with Nina across at least 2 separate sessions, or at least one use of a Sentinel or scheduled task. Sign-up alone does not qualify, and rewards are granted once our checks pass. Points are valid for 180 days from the date they are issued and expire automatically if unused. We verify abnormal or duplicate participation and may revoke or claw back points that do not meet the reward conditions; partnership and ambassador programmes follow their own terms.

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 supports five EVM chains and Solana, with cross-chain routed through LI.FI).
• 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.
