What Defined.fi is

Defined.fi started in 2021 as a charting platform for on-chain tokens, the corner of crypto that mainstream charting sites covered badly. The team ended up building its own data engine to feed it, and that engine became Codex, the API now used by products across the industry. Defined is the consumer face of that data: a trading terminal that pairs real-time charts for more than 50 million tokens across 67 chains with built-in trading, wallet tracking, and alerts. A Codex case study puts Defined at more than 250,000 users a month, and the project is backed by firms including Version One, Alliance, Compound, and Mark Cuban Companies.

The pitch is consolidation. Instead of one tab for charts, another for a DEX, a third for perps, and a Telegram group for alerts, Defined puts spot tokens, Hyperliquid perpetual futures, and Polymarket prediction markets behind one account and one balance, on the web, iOS, Android, and Telegram. You can also explore as a guest without signing up.

Core features

Token discovery. Search any token, contract, or wallet across every supported chain, filter by gains, volume, or activity, and watch new launches as they happen, including launchpad migrations with reminders before a token graduates. Crucially, trending cannot be bought: Defined states that projects cannot pay or sponsor their way onto its trending lists, and its stats block advertises zero paid trending spots.

Multicharts and watchlists. The web terminal runs multiple live charts in one grid, with watchlists, advanced filters, and heavy layout customization. For anyone who tracks a basket of small caps, this is the feature that replaces a wall of browser tabs.

Wallet tracking and alerts. Watch any wallet and get real-time trade alerts across Solana, Ethereum, and Base, delivered in the browser, the mobile apps, or Telegram. The Telegram bot also answers token lookups inside group chats with instant token cards.

An AI companion. Defined includes an assistant that turns a plain-language question into a trading plan across spot, perps, and prediction markets. Treat its output as a starting point for your own checks, not as advice.

Trading and fees

Research is free and there is no subscription tier at all: Defined says plainly that it offers no paid plan, discounts, or trials. It makes money only when you trade. Spot trading covers Solana and the main EVM chains with market, limit, stop, and recurring orders, including cross-chain swaps, so there is no manual bridging step. Perpetuals run on Hyperliquid, long or short with leverage, from the same balance. Prediction markets run on Polymarket, with charts and a leaderboard of top prediction traders next to your other positions.

ActivityCost
Charts, data, wallet tracking, watchlists, alertsFree
Spot trades0.50% per trade, $0.25 minimum
Perpetual futures0.05% per trade, plus Hyperliquid fees
Prediction markets0.50% per trade
SubscriptionNone, there is no paid tier

Fees as published on Defined's About page, checked 12 November 2026. One honest wrinkle: Defined's own developer documentation lists lower fees for perps (0.025%) and prediction markets (0.25%) than its About page does. Until the two agree, treat the fee shown in the app at order time as the real one. A 0.50% spot fee is also worth weighing against trading the same token directly through a DEX aggregator: you are paying for the terminal, the routing, and the convenience.

Token safety: the risk verdicts

The feature that matters most for beginners is the quietest one. Every token on Defined, in search results, trending lists, and new launch feeds, carries a risk verdict from the Codex risk engine: a label (NEUTRAL, CAUTION, HIGH_RISK, or SCAM, with VERIFIED for established tokens) and a score from 0 to 100. Behind the label sit reason codes for proven honeypots detected by trade simulation, holder concentration, sniper and bundler wallets in the early buys, wash trading, unlocked or thin liquidity, and the creator wallet's track record. The Telegram card above shows the same idea in miniature, flagging an active mint authority before you ever open the chart.

Two limits to keep in mind. The score is a heuristic, not a probability and not an audit: a token can score clean and still collapse when a team wallet sells. And brand-new tokens may show as not yet analyzed until the engine has enough trades to judge. Used properly, the verdict is a fast first filter, not a buy signal. If you want to scan a contract before trading it, our free Token Safety Checker runs the same Codex engine alongside GoPlus contract checks.

Getting started

Open Defined.fi and explore as a guest first: search a few tokens you already know, check their risk verdicts, and build a watchlist. When you are ready, create a free account to sync watchlists and alerts across web and mobile, and set Telegram alerts for the wallets you follow. Fund a balance only when you intend to trade, compare the in-app fee quote on your first small trade against the table above, and size new-token trades as if they could go to zero, because many do.

Pros and cons

What stands out

  • Research is genuinely free, with no subscription tier at all
  • 50M+ tokens across 67 chains in one terminal
  • A risk verdict on every token, powered by the Codex engine
  • Trending cannot be bought: zero paid placements
  • Spot, Hyperliquid perps, and Polymarket predictions in one account
  • Multicharts, wallet tracking, and alerts on web, mobile, and Telegram

What to watch

  • 0.50% spot fee adds up versus trading directly on a DEX
  • Perps are Hyperliquid only, predictions are Polymarket only
  • Fee figures differ between the About page and the docs
  • Risk scores are heuristics, not audits or guarantees
  • Trading coverage is narrower than data coverage
  • New tokens and leveraged perps remain extremely high risk

Verdict

Defined.fi is the rare trading tool whose free tier is the whole product: serious multi-chain charts, wallet tracking, and alerts with no subscription wall, funded by a clear trading fee instead of paid rankings. The built-in risk verdicts give it an edge over pure charting rivals for anyone wading into new tokens, and having perps and prediction markets in the same terminal is genuinely convenient. Power traders may balk at the 0.50% spot fee on large orders, and the fee discrepancy between its pages needs tidying, but as a research home base it is easy to recommend. Start with the free charts and verdicts; trade small while you learn.

Frequently asked questions

What is Defined.fi?+

Defined.fi is a multi-chain crypto trading terminal built by the team behind the Codex data API. It combines real-time charts and data for more than 50 million tokens across 67 chains with built-in spot trading, Hyperliquid perpetual futures, Polymarket prediction markets, wallet tracking and alerts, on the web, iOS, Android and Telegram.

Is Defined.fi free?+

Yes. Charts, market data, wallet tracking, watchlists and alerts are free, and there is no paid subscription at all. Defined charges only when you trade: 0.50% on spot trades (with a $0.25 minimum), 0.05% on perpetuals plus Hyperliquid's own fees, and 0.50% on prediction markets, per its About page. Its developer docs list lower perps and prediction fees (0.025% and 0.25%), so check the fee shown in the app before you trade.

What are token risk verdicts on Defined.fi?+

Every search result and new launch on Defined carries a risk verdict from the Codex risk engine: a label such as NEUTRAL, CAUTION or HIGH_RISK plus a score from 0 to 100, built from reason codes covering proven honeypots, holder concentration, sniper and bundler wallets, wash trading, liquidity risk and the creator wallet's history. It is a heuristic score, not a guarantee. Our free Token Safety Checker uses the same engine if you want to scan a contract before you trade.

Can projects pay to trend on Defined.fi?+

No. Defined states that projects cannot sponsor or pay to appear on its trending lists: trending is calculated from market activity, and its stats block advertises zero paid trending spots. That matters because paid placement is common on token discovery sites and quietly distorts what looks popular.

Which chains does Defined.fi support?+

Its supported chains list names 67 networks, including Solana, Ethereum, Base, BNB Chain, Polygon, Arbitrum, Optimism, Avalanche, Tron, Aptos and Sui. Trading is narrower than data coverage: spot trading runs on Solana and the main EVM chains, perpetuals run on Hyperliquid, and prediction markets run on Polymarket.

Is Defined.fi safe for beginners?+

Defined itself is a data and trading interface, and the research side is free and beginner-friendly. The risk sits in what you trade through it: brand-new tokens and leveraged perpetuals can go to zero or liquidate you fast. Use the risk verdicts, start with watchlists and alerts rather than trades, and never trade money you cannot afford to lose.
