What is Nansen? Review nansen.ai + promo code 10% off Pro subscription

If you’ve spent any real time onchain, you already know the problem: everything is transparent, but almost nothing is obvious.

Wallets are pseudonymous, flows move fast, and by the time a narrative hits Twitter, the best entries are usually gone. That’s basically why I use Nansen.

What nansen.ai is

Nansen is an onchain analytics platform that takes raw blockchain data and turns it into something you can actually act on.

The core idea is simple: label wallets at scale, track what those wallets do across many chains, and surface the patterns in dashboards, alerts, and search.

Nansen has millions of labeled addresses and supports a wide multichain view, so you can see not just “what happened,” but who is moving and where they’re moving to.

Think of it as the bridge between block explorers and real market insight. Instead of staring at endless tx hashes, you get context like “this wallet belongs to a top fund,” “these are smart money net inflows,” or “this token is getting accumulated by high performing traders.”

How it helps

I use Nansen for three main jobs:

1. Discovery
   I want to know where attention and capital are going before it becomes a headline. Smart Money dashboards and live DEX tracking let me see what consistently profitable wallets are buying in real time, across chains.
2. Due diligence
   When a token starts trending, the first thing I check is holder quality and flow direction. Are good wallets accumulating or are insiders distributing? Nansen’s labeling and wallet profiler makes that fast.
3. Defense
   The market moves brutally fast. Alerts on key wallets, tokens, or protocols help me catch early signs of risk or rotation. That’s been a legit edge in volatile weeks.

In short, Nansen helps me trade with evidence instead of vibes. Not because it predicts the future, but because it shows the present clearly.

What’s unique about Nansen

A bunch of tools show charts. Fewer show flows. Nansen’s edge is turning flows into identity and intent.

• Wallet labels at scale: Nansen is famous for labeling hundreds of millions of addresses and tagging “smart money” cohorts so you can follow the most informed actors, not just price candles.
• Smart money methodology + pnl focus: the Smart Money dashboard doesn’t just list whales, it highlights wallets with proven performance and shows what they’re doing now.
• Multichain, one interface: I don’t want to hop between explorers for every ecosystem. Nansen pulls activity from many major chains into one place.
• AI-assisted search and signals: built-in AI search and market signals help reduce the “needle in a haystack” problem when scanning new trends.

That combination makes it feel less like a data terminal and more like a real-time market map.

Basic (free) vs Pro plan

Basic/free plan
Good for getting oriented and doing light research. You get essentials like smart search, basic dashboards, some AI signals, and baseline wallet or token views, but you’ll hit limits if you’re doing serious daily tracking.

Pro plan
This is what I’d call “full Nansen.” Pro unlocks deeper smart money tooling, more labels, advanced filters, unlimited alerts and watchlists, richer wallet PnL views, and exports for people who like to go spreadsheet-mode.

Pricing as of late 2025 is $49/month on annual billing or $69 month-to-month.

Given what Pro used to cost historically, the new pricing is honestly a steal if you’re an active trader.

If you’re thinking about upgrading, you can use the promo code “kaito” or just sign up through nsn.ai/kaito. It knocks 10% off a Pro subscription on your first checkout.

No pressure, but if you’re already headed that way, might as well save a bit.

That’s the quick tour.

Nansen won’t make decisions for you, but it absolutely makes the market easier to read.

For me, it’s been one of those tools that quietly compounds edge over time: better entries, fewer bad chases, and way more confidence in why I’m in a trade in the first place.

As always, this is just how I use it and not financial advice.
