Best Crypto Wallet Trackers and On-Chain Analytics in 2026
Last verified: November 12, 2026 (Cielo's Ethereum trading and Whale-plan tools added from its announcement channel). October 29, 2026 (Nansen's address count re-read). October 25: Arkham's October 20 changes added from its announcement; Nansen's fee ladder confirmed on its official pricing page (October 11); Arkham's announcements page re-read in full (October 17); GMGN's wallet-analysis filter added (October 15). Referral links marked where present. One structural note before anything: wallet tracking is read-only. You paste public addresses, you connect nothing, you deposit nothing, so this is the rare corner of crypto tooling with no custody risk at all.
Every profitable memecoin trader you follow is being followed too. Wallet trackers are how: paste an address, get alerted when it moves, study its history before you copy anything.
The tools below run from free to $199 a month, and the right one depends on whether you want alerts in Telegram, institution-grade labels, or a bridge straight into trading.
The comparison
 Cielo |  Nansen |  Arkham |  GMGN |   DeBank / Dexscreener | |
|---|---|---|---|---|---|
| Price | Free (250 wallets), Pro $59/mo, Whale $199/mo | Free tier, Pro $49/mo billed annually ($69 monthly). Trades at 0.75% on the entry tier, down to 0.10% by points tier (official pricing page, Oct 11, 2026) | Free labels; full history paid since October 20, 2026 ($1,500/mo) | Free to browse, 1% when you trade | Free |
| Coverage | Tracks 30+ chains | 37 chains, including Robinhood Chain | 16+ chains, entity-level labels | 14 chains (in-app, Oct 29, 2026), trader wallets; its app-store listing still says six | Broad EVM / 60+ chains of charts |
| Alerts | Real-time in Telegram and Discord; in our daily use since August 14, 2026, alerts landed within seconds of the on-chain trade | Smart Alerts, custom triggers | Address and entity alerts | In-platform | Watchlists, no push depth |
| Signature strength | Alert-driven tracking with trading and copy trading in one product (0.6% manual, 1% on agents) | Smart Money labels, 500M+ labeled addresses per Nansen (Oct 29, 2026) | Names the entity behind the address, free; API now also sold as an MCP server (Oct 6) and on Google Cloud Marketplace (Oct 14), prices unpublished | Trader PnL histories feeding copy trading; since Oct 15, 2026 its wallet analysis flags PnL that came from tokens the wallet launched itself | Portfolio view / fastest charts |
| Watch out for | Agent trades cost 1%, not the 0.6% headline (custody is documented: Turnkey) | Price, and most reviews still cite its old higher tiers | The 2023 dox-to-earn history, below | Solana-first bias | No serious alerting |
| Coverage on this site | Cielo Finance review | This page | This page | GMGN review | This page |
Verdicts by what you actually want
More: where Cielo's edge is, and where GMGN closes the same loop
GMGN closes a similar loop for trader wallets; Cielo's edge is the real-time alerting and the agent controls (filters, sizing, backtesting) that GMGN's simpler mirroring does not match. Details, including the custody caveat on its trading side, in the review.
More: what it costs after the 2026 repricing
At $49 a month on the annual plan after the 2026 repricing, it is now within reach for a serious individual, not just funds.
Most competitor reviews still quote the old $99 to $129 tiers; check the current page, not the blogs.
If it is really Cielo or Nansen you are deciding between, the two are compared head to head in Cielo vs Nansen.
More: where its labels draw a blank, and who fills it
Its labels skew toward majors, funds and exchanges; for a memecoin wallet created last week it will often draw a blank, which is where GMGN takes over.
Read its history section below before deciding how you feel about the company; the free tier still costs nothing and asks nothing, and the October 20 limits are in that section.
More: what it finds that Nansen and Arkham have not labeled yet
On its home turf (fresh Solana memecoin wallets) it routinely surfaces what Nansen and Arkham have not labeled yet, and that is not a small thing: it is the discovery end of the whole loop described below.
Since October 15, 2026, its wallet analysis also traces where a wallet's profit came from, a real trade or a token the wallet launched itself; over 50% from its own launches fails the check. That is the first tool here to filter out the launch-and-dump wallets that top a leaderboard.
More: the free stack with Dexscreener, and what you give up
Pair it with Dexscreener for charts and you have a workable free stack that covers most of a beginner's needs; what you give up is real alerting, which is exactly what the paid tools sell.
How to track whale wallets, the working method
The question everyone asks, "how do I find whale wallets?", has an unglamorous answer: you do not find them, you harvest them. Pull the early buyers of a token that pumped, keep the ones that were early more than once, feed them into a tracker, and watch a new wallet for a week before you act on it.
More: the four-step harvest loop, and why it works the same on a brand-new chain
When a token pumps, open its top holders or its early buyers on Dexscreener or GMGN. Pull the addresses that got in before the move.
Check each one's history. A wallet that was early once is luck. A wallet that was early five times is a lead. Feed those into a tracker: Cielo if you want the alert in Telegram within seconds, Nansen if you want to know who the wallet probably is first.
Then let the alerts build your shortlist. Size small when you act. Past earliness is not a promise, as the survivor-bias rule in our copy trading guide explains.
On Solana and for memecoins this loop is the whole game. It works identically on a brand-new chain the day it launches, which is why our day-one method assumes you already have a tracker ready.
Nansen, straight answers
Is Nansen worth it? If you trade on information (following funds and smart wallets into positions), the label database is the moat and $49 a month on the annual plan is defensible.
If you trade memecoin launches on reflex, it is the wrong tool: Cielo or GMGN serve that faster and cheaper.
More: who runs Nansen, and its funding
The company itself is solid by this site's standards: founded 2019, run by Alex Svanevik, $75M Series B led by Accel, no incident on record.
Nansen trades now, and this is what it costs
Since January 2026, Nansen is also a trading venue. Tokens and Hyperliquid perps, from inside the app, gasless, routed through an aggregator (Relay on the quote we pulled). The Nansen Wallet is an embedded wallet with a "View Private Key" button and optional MFA, the same custody model as FOMO: keys yours, on their infrastructure.
The fee depends on your Nansen Points tier, not on your Free or Pro plan. Base rate 0.75%, and the tiers cut it from there:
| Points tier | Fee discount shown in-app | Fee (official pricing page, Oct 11, 2026) |
|---|---|---|
| Standard (start) | none (10% off for referred users) | 0.75%, or 0.675% referred |
| Green (1,000 NXP) | up to 40% off | 0.45% |
| Ice | up to 67% off | 0.25% |
| North | up to 77% off | 0.175% |
| Star | up to 88% off | 0.10% |
Perps pay Hyperliquid's base fee plus a Nansen builder fee, 0.08% at the entry tier down to 0.01% at Star. Gasless applies above a $10 trade. We have not executed a trade yet: the quote screen below is a quote, not a filled order.
More: the quote we pulled on September 5, and how the official pricing page confirmed the ladder
Quote pulled on September 5, 2026, on a 200 USDC buy of SOL: fee line "Standard 0.675%", price impact 0.10%, no gas.
Nansen's own pricing page, read on October 11, 2026, lists the same ladder: 0.75%, 0.45%, 0.25%, 0.175%, 0.10%, with one fee structure and no maker/taker split.
What it means: even at the entry tier, Nansen is cheaper than every Telegram bot on this site (1%) and has no minimum fee, where FOMO charges a $0.95 floor on small Solana orders. The "0.25%" that January press coverage reported is the Ice tier, not what a new account pays. Reaching Green takes 1,000 NXP; the app credits points for trading, staking, subscriptions and referrals.
Nansen alternatives? Honest answer by budget: Arkham free for entity intelligence, Cielo from free to $59 for alert-driven tracking with trading attached, and the DeBank plus Dexscreener stack at zero for portfolio and charts. Nothing free replicates the Smart Money labels; that is what the subscription buys.
Cielo, new since our last pass. Ethereum trading went live on Cielo on October 30, 2026, and on November 7 it added a Related Wallets Visualizer and two research agents (CEX Research, New Wallet) to its Whale plan at $199 a month, which Cielo itself presents as tools "that run into the thousands per month on Arkham and TRM". That price comparison is Cielo's claim; Arkham does not publish an Enterprise price we could read source.
Arkham, including the part its fans skip
The product is excellent and free: entity-labeled exploration that names the fund, exchange or founder behind an address, with flow visualizations.
The history deserves equal billing: in July 2023 Arkham launched a marketplace paying bounties to deanonymize wallet owners, nicknamed dox-to-earn, and the same month its referral links leaked registered users' email addresses.
More: the Intel Exchange, the email leak, and the exchange Arkham closed in 2026
In July 2023 Arkham launched its Intel Exchange, a marketplace paying bounties to deanonymize wallet owners, which the industry promptly nicknamed dox-to-earn.
The same month, its referral links were found leaking registered users' email addresses encoded in the URL. The CEO defended the model and the platform moved on.
Separately, Arkham launched a trading exchange in 2024 and shut it down in February 2026 after thin volume. The analytics platform is unaffected.
From our own use, dated. Since September 11, 2026, Arkham links FOMO usernames and Pump.fun profiles to their wallets source; we typed our own FOMO name on September 12 and got our X account, our wallets and our full history back. Useful for tracking, uncomfortable for the tracked.
What changed on October 20, 2026. Arkham moved part of the free platform behind Arkham Enterprise: free users now see only the 100 most recent transactions of an address or entity, and lose transaction filters, the Tracer, the counterparties section and the creation of new custom labels source. All labels, the Visualizer, the block explorer, tags and prediction markets stay free. Arkham's own guide (October 21) puts it at $1,500 a month after a 14-day free trial, for approved accounts only source; there are grants for independent investigators. We are re-checking which part of the September 12 lookup still works on a free account.
More: no bookmarks in Arkham, and the workaround we use
One thing you will not find: a way to bookmark an entity so you can come back to it without searching again. We looked on September 13 and Arkham's docs confirm there is no favorites feature. The workaround is a Dashboard with the entities you follow, or Tracked Entities, which does the alerting side.
Three dated additions. Robinhood Chain has been live on Arkham since July 22, 2026. Its API became an MCP server on October 6 and a listing on Google Cloud Marketplace on October 14, paid in Google Cloud credits, with no price published in either announcement. And a real use, not a feature: the funds stolen through tampered Ledger devices sold by a reseller were traced publicly with Arkham in October, about $87M by its count on October 10; the case is on our safety page.
Use it for what it is: a free intelligence tool with no paywall on the labels, run by a company whose relationship with privacy you should know before creating an account.

FAQ
What is the best free crypto wallet tracker?
For alerts, Cielo's free tier (250 wallets into Telegram); for who owns an address, Arkham's free labels; for a portfolio view, DeBank. The three together cost nothing, and the comparison table shows what each one does.
How do I track whale wallets on Solana?
Harvest early-buyer addresses from pumping tokens on GMGN or Dexscreener, verify each wallet's repeat performance, then feed the good ones into Cielo for Telegram alerts. The full loop is described above; it takes an evening to set up.
Can a wallet tracker steal my funds?
No. Tracking is read-only on public data: you never connect a wallet or sign anything. The only risk arrives when a tracker also offers trading and you deposit into it; that side is covered in our custody guide.
What is the best memecoin wallet tracker?
GMGN to find fresh Solana memecoin wallets that Nansen and Arkham have not labeled yet, free to browse, and Cielo to get pinged in Telegram when they buy, free for up to 250 wallets. The full loop is in the working method above.
