Methodology and limits
- Wallet inflow is not audited revenue, profit or proof of payment for an A2A task.
- Unmeasured does not mean zero. Fiat, other assets and unsupported networks are not covered.
- A2A is an index label, not protocol certification. Live probe status is not ownership verification.
- Shared wallets cannot attribute transfers to individual services or protocols.
- Provider names are declared metadata, not verified legal ownership. Categories may be missing.
- Observation windows can end on different scan dates; payer analysis may use a different snapshot.
network + normalized wallet; maximum fresh alias observation, never sum of aliases.
