Crypto portfolio trackers

See every coin you own — in one read-only view.

Holdlens is an independent guide to crypto portfolio trackers: the apps that pull your holdings from every wallet and exchange into a single screen. We judge them on connections, read-only support, DeFi and NFT coverage, privacy and price — and we never tell you what to buy.

What Holdlens is for

Holdlens does one job: it helps you choose and safely use a crypto portfolio tracker — an app that gathers your holdings from every wallet and exchange into a single view. Start with the best crypto portfolio trackers, compared, where each tool is judged on its connections, read-only key support, DeFi and NFT coverage, privacy model and price.

A tracker exists to answer one question — “what do I actually own, and what is it worth right now?” — without logging into five apps. It reads your balances and displays them. It should never be able to move your money, and a good one never asks to. If you are brand new to this, our guide to how to track your crypto portfolio walks through every safe way to connect, step by step.

How we judge a tracker — and what we refuse to do

We rank on what a tracker is actually for: how many exchanges and chains it connects to, whether it supports read-only (view-only) API keys, how honestly it handles DeFi and NFTs, what it does with your data, and what it costs.

What we refuse to do matters just as much. No coin picks. No price predictions. No “next 100x.” A tracker showing a green number is not telling you to buy, and we will not either. Read why read-only API keys are the one setting that matters and what these apps actually know about you before you connect anything.

Straight answers

What is a crypto portfolio tracker?
A crypto portfolio tracker is an app or website that pulls the balances from your wallets and exchange accounts into one screen, so you can see everything you own — and its combined value — in a single place instead of logging into five apps. Most connect either by a read-only exchange API key, by a public wallet address, or by a spreadsheet-style manual entry. A tracker only reads and displays your holdings; it does not, and should not, be able to move them.
Is a portfolio tracker safe to connect to my exchange?
It can be, if you connect it correctly. The one rule that matters: use a read-only (view-only) API key with trading and withdrawals switched off, which most major exchanges let you create in a few clicks. That way, even if the tracker is hacked, an attacker can see your balances but cannot move a cent. Never give a tracker a full-access key, and never type your seed phrase or exchange password into one. The real trade-off is privacy, not theft: you are handing a third party a live map of what you own.
Does a tracker tell me what to buy or sell?
No — and you should be wary of any that claim to. A tracker shows what you already hold and how its value has changed; that is a mirror, not advice. A portfolio being up is not a buy signal and being down is not a sell signal. We rank trackers on how well and how safely they show your holdings, and we never publish coin picks or price predictions. What you do with the numbers is your decision, ideally after your own research.
What is the best free crypto portfolio tracker?
For most people the honest answer is a free tier of a mainstream tracker plus the dashboards you already have. CoinStats and Delta both offer capable free apps; Koinly and CoinLedger track a portfolio free and only charge when you need tax reports; and your exchange (Coinbase, Kraken) and wallet (MetaMask Portfolio) already show their own holdings for nothing. If privacy is the priority, an open-source, local tool like Rotki keeps the data on your own machine. Free tiers usually cap the number of connections or hide some history — not the core tracking.
Tracker or a spreadsheet — which should I use?
A spreadsheet is private, free and fully under your control, and it is genuinely the right tool if you hold a handful of coins and check occasionally — but you update prices and balances by hand, and it will not see DeFi or NFTs on its own. A connected tracker auto-syncs across many exchanges and wallets and handles DeFi and NFTs, at the cost of sharing your holdings with a third party. Many people run both: a tracker for the day-to-day view, a spreadsheet as a private backup of what they actually own.
