How to Set Up a Portfolio Tracker
Via Wallet Connection (Read-Only)
- Go to Zerion or Zapper
- Click “Connect Wallet”
- Select “Watch only” or “Read-only” mode
- Enter your wallet address
- The app shows all tokens across all chains
Safety: Read-only mode means the app can only view — it cannot initiate transactions. Your funds are safe.
Via Exchange API
- Go to CoinTracker or Koinly
- Select your exchange (Coinbase, Binance, Kraken)
- Generate API keys on the exchange (enable “Read” only — never enable “Trade” or “Withdraw”)
- Paste the keys into the tracker
- Transactions import automatically
What to Track
| Item | Why |
|---|---|
| Total portfolio value | Know where you stand |
| Asset allocation | Are you too concentrated? |
| Unrealized P&L | How much are you up/down? |
| DeFi positions | Lending, farming, staking balances |
| Transaction history | For tax reporting |
Verdict
For most people: Zerion for daily portfolio tracking (free, connects to wallets, shows everything). CoinTracker or Koinly for tax season (imports from exchanges, calculates gains).
Track your portfolio monthly. Review your allocation quarterly. Rebalance if needed. Don’t check daily — it leads to emotional trading.
