Best Crypto Portfolio Tracker in 2025

Keeping track of your crypto portfolio across multiple wallets and exchanges is one of the biggest pain points in the space. A good portfolio tracker saves you hours every week and ensures you never lose track of tokens hiding in forgotten wallets. Here is what to look for in 2025.

What makes a good portfolio tracker?

The essentials are multi-chain support (at minimum Ethereum, Solana, BSC, and major L2s), automatic wallet scanning (paste an address and see everything), real-time price data, profit/loss calculations, and clean UX that doesn't require a finance degree to navigate. Bonus features include tax reporting integration, DeFi position tracking, NFT valuation, and whale alerts.

The main options

CoinGecko and CoinMarketCap offer basic portfolio features, but they are primarily price-tracking sites. You manually add transactions, which is tedious and error-prone. They work fine if you only hold a few tokens on one exchange.

Zerion and Zapper are excellent for DeFi users on EVM chains. They automatically detect LP positions, staking, and lending. However, they have limited support for non-EVM chains and no built-in tax reporting.

Koinly and CoinTracker focus heavily on tax reporting. They connect to exchanges via API and can import wallet data. The downside is pricing — both charge £100+ per year for active traders, and the free tiers are very limited.

DeBank is a strong free option for DeFi tracking across EVM chains. It has deep protocol support and a clean interface. However, it lacks Solana support, tax features, and exchange integration.

What to prioritise based on your situation

If you are a casual holder with tokens on one or two exchanges, a simple tracker like CoinGecko's portfolio is sufficient. If you are active in DeFi across multiple chains, you need something that auto-detects protocol positions — Zerion or DeBank. If tax reporting is your priority (particularly UK-specific rules), you need a tool that understands HMRC share-pooling and the 30-day rule.

The gap in the market

Most trackers force you to choose between good DeFi tracking and good tax reporting. Few handle both well, and even fewer are built specifically for UK users. The UK has unique tax rules (share pooling, the 30-day rule, CGT allowances) that generic international tools often get wrong.

Privacy considerations

Be cautious with trackers that require exchange API keys with trade permissions. A read-only API key is all that is needed for tracking — never grant withdrawal access. For wallet-based tracking, check whether the service stores your addresses or queries them on-demand.

CryptoLens combines multi-chain wallet scanning, DeFi position detection, NFT tracking, and UK-specific tax calculations in one free tool. Just paste any Ethereum, Solana, or BSC wallet address to see your complete portfolio — no sign-up required.
