How far back we can rebuild your history
How WhereItGoes reconstructs your full transaction history from 11 exchanges and 52 chains, and exactly where each venue's own API stops, which is the real ceiling on any tracker.
How it works
The method, not just the result.
A portfolio tracker is only worth as much as the reasoning behind its numbers. These pages set out exactly how ours are produced, including the parts where we refuse to answer and the parts we have not built yet.
Moving your own coin is not a sale
How WhereItGoes detects that a withdrawal from one account and a deposit into another are the same coin moving, so a transfer between your own wallets is never counted as a sale plus a repurchase.
How we calculate cost basis and profit
WhereItGoes computes realised profit with FIFO on the server and shows average cost on asset pages, values income at its receipt-day price, and refuses to invent a cost basis it does not know.
How we decide what a token is worth
WhereItGoes prices on-chain tokens by their contract address rather than their ticker, falls back across several price sources, and leaves genuinely unpriceable tokens unpriced instead of guessing.
How we handle spam and scam tokens
WhereItGoes classifies junk tokens by contract address rather than by ticker, keeps them out of your totals and lists, and puts them in a recoverable trash instead of deleting them.
What we do with your keys and your data
WhereItGoes reads exchange accounts through read-only API keys and wallets through public addresses only. It never takes custody, never asks for a private key or seed phrase, and has no mechanism to move funds.
What WhereItGoes does not do
The honest limits of WhereItGoes: no downloadable tax reports, no live DeFi position valuation, minimal NFT support, no mobile app, and the per-exchange history ceilings we cannot get around.
Why we publish this
Two reasons. The first is that these decisions are the product: anyone can show you a balance, but the difference between a number you can act on and a number that merely looks confident is the reasoning underneath it.
The second is that it keeps us honest. A method written down in public is one we have to either follow or change, and it makes the limits legible instead of leaving you to discover them at the point they matter.
