Automated analysis, not an audit: zero findings does not mean a contract is safe.

90-day total + 90 days of daily history

USDC on Solana. Inflow to a wallet, not proof that every transfer was a paid call. Solana: measured since 2026-10-30; earlier windows are a lower bound.

How it was settled and checked

x402-settled: $3.01 (99%) · 4 transfers sent by a known x402 facilitator (PayAI)

Other: $0.03 plain transfers sent by the payer · $0.00 other contract calls.

Reproducible via SPL-token transfers to the wallet's USDC token accounts (getSignaturesForAddress + getTransaction). How we classify

Rolling 30-day inflow ↑ +$1.01 since 2026-10-31

2026-10-31 2026-11-12

Peak: $3.04

Payment authenticity How we measure this →

Concentrated payers 3/5

Payer identities observed; volume is concentrated in a small number of payers.

The settlement wallet is shared with other indexed agents, so inflow cannot be attributed to this agent alone.

$2.01 assessed 3 transactions 2/13 days active · 30d window Payer identities available

A low label reflects what we can observe, not a finding about the operator.

How this was checked

2 evidence caveats · measured 2026-11-12.
Checks: daily volume aggregate, active day cadence, amount regularity, spike concentration, settlement wallet overlap, payer uniqueness, payer concentration, payer recurrence, payer payee overlap.
Sources: agent revenue daily, agents payment wallet, agent payment transactions.
