interOSObserve EVM and Solana wallets together, identify source funds and compare saved snapshots. Each wallet retains its own funds and signing authority.
Wallet labels and snapshots are stored in this browser. Adding an address does not establish ownership or grant permission to spend.
Capture observations above, then compare any two for the same wallet set. Quantity effects include trades, transfers, fees and other balance changes; they are not classified as profit or loss. No historical balances are invented before your first snapshot.
