How to track your entire crypto portfolio in one place

The recipe for seeing everything you own in one number has two ingredients: public addresses for everything on-chain, and read-only API keys for everything on exchanges. Feed both into one tracker and the total assembles itself, updating live, without any app ever gaining the power to touch a coin. The rest of this guide is the practical order of operations.

Why portfolios shatter in the first place

Nobody plans to run five venues. It accrues: an exchange for on-ramping, a hot wallet for DeFi, a hardware wallet for savings, an L2 for cheap fees, a perp venue for trading. Each shows its own slice in its own app with its own numbers. The person holding all five slices is the only place the full picture exists, and human memory is a terrible database.

Step one: wallets, by address

Every wallet you own is trackable by pasting its public address, including the hardware wallet you never connect anywhere. Address-based tracking is read-only by nature: no signature, no approval, nothing that lets a site move funds. Add every address you control, including the dusty ones; forgotten wallets are where surprises live.

Step two: exchanges, read-only

Exchange balances sit behind logins, so they need read-only API keys: credentials that can see balances and history but can never trade or withdraw. Create one per exchange, enable nothing beyond reading, and connect. The walkthrough for Binance is here; the pattern is identical everywhere. If your exchanges are OKX, Coinbase and Kraken, the three-exchange setup covers where each one keeps balances its API reports separately. Prediction markets follow the same split: Polymarket is read from a public address, while Kalshi needs a read-only key.

Step three: the parts dashboards forget

• DeFi positions: LP shares, lending deposits and staked assets do not show up as wallet balances; the tracker has to decode the protocols.
• Perps: accounts on Hyperliquid, Lighter, dYdX and GMX carry exposure and funding that belong in the total.
• NFTs: illiquid, but not worthless; they belong in the picture, priced honestly.
• Staked and vesting balances: locked is not gone. A total that skips them undercounts you.

What one view changes

With everything in one place, questions become answerable: what is my real allocation, what changed since yesterday, which slice earned and which quietly bled. TrueHold was built for exactly this assembly job: 180+ chains, exchanges via read keys, DeFi, NFTs and perps, one total with a composition. Long-term holdings and a trading stack can also sit in separate portfolios, each with its own total. Set it up once; the picture stays live.
