Completeness is tested
A partial history can look complete. Every figure in the app depends on having all of the wallet's activity, so completeness is tested rather than assumed.
The nonce test
An externally owned account's nonce increases by exactly one for every transaction it sends — including transactions that revert. Rebuild the sequence, and any gap is a missing record, not a quirk of the history.
This is stronger than trusting a counter from an explorer, which can be stale or wrong, and stronger than comparing totals, which cannot tell you which records are absent.
What the test says now
171,591 transactions are missing from the sequence. Every trade is accounted for — trades move tokens and therefore appear in the logs, which were pulled independently over the full range — so profit and loss is complete. The reverted-attempt count is not.
Balance reconciliation
The second check: ETH in, minus ETH out, minus gas, should equal the on-chain balance at the snapshot block. Public RPC on this chain is not archival and refuses historical balance queries, so this check currently reports not run rather than passing quietly.
The app shows the state of both checks in the snapshot stamp, and in full on the Method tab.
Why one address is not proof
This is the history of one address. It is not proof that the team has no others. Control of this address can be demonstrated by signing a message from it, without revealing any key — until that signature is published, the link between the app and the desk rests on our word, which is weaker.
