What we read, and how
- Exchanges: a read-only API key you create yourself, with no trade or withdraw permission. We read spot trades, converts, deposits, withdrawals, fees and, where the venue exposes them, fiat purchases and Earn balances.
- Wallets: a public address, or a name handle like vitalik.eth. Nothing to create and nothing to store, exactly like looking at a block explorer.
- Coverage is 11 exchanges and 52 chains.
History is reconstructed rather than imported. Where a venue exposes only a ledger rather than a trade list, we rebuild the trades from the ledger, which is how converts, dust conversions and staking movements are recovered.
The ceiling is the venue, not the tracker
This is the number nobody publishes in a comparable place, and it decides how much history any tool can show you, ours included. If an exchange will not serve data older than 30 days through its API, no tracker can reconstruct year-old trades from it, whatever the marketing says.
| Exchange | How far back its API goes |
|---|---|
| MEXC | About 30 days of trades and 90 days of transfers. Older history is not retrievable by anyone, us included. |
| HTX | About 120 days of fills and 12 months of transfers. Older history is not retrievable by anyone, us included. |
Every other exchange we support returns full history with no API window. That is 9 of 11.
If you are choosing a tracker and your history matters, ask this question of every tool you try, and be suspicious of anyone who answers it with a number instead of a per-venue table.
Keeping it current
After the first rebuild, syncing is incremental: we resume from where the last one finished rather than re-reading everything. On Binance, fills arrive in seconds over a live account stream instead of waiting for the next sync.
Free accounts get the complete history for every account they connect. What the free tier limits is how many accounts you connect, never how far back the picture goes.
