onchain-health.mick8511.workers.dev · onchain-health.mick8511.workers.dev

Checks whether a signature was made by a claimed EVM address: EIP-191 personal_sign messages, EIP-712 typed data or a raw 32-byte digest, verified by ecrecover for wallets or ERC-1271 isValidSignature for smart-contract wallets (Safe, Coinbase Smart Wallet) on Ethereum, Base, Arbitrum, Optimism or Polygon. Returns validity, method, recovered signer and digest. Free sample: https://onchain-health.mick8511.workers.dev/sample

How it was settled and checked
x402-settled: $0.01 (100%) · 2 transfers sent by a known x402 facilitator (Coinbase)
Other: $0.00 plain transfers sent by the payer · $0.00 other contract calls · 1% of $0.78 classified so far.
Cross-check: Coinbase's Bazaar reports 173 calls in 30 days across 52 resources; we observed 193 transfers (2 facilitator-settled). Neither counter is assumed correct.

Payment authenticity How we measure this →
Independently paid 5/5

Many distinct payers observed, low concentration, repeat demand, and no self-referential payment signal.

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

$0.79 assessed 183 transactions 15/30 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

Checks: daily volume aggregate, active day cadence, amount regularity, spike concentration, settlement wallet overlap, payer uniqueness, payer concentration, payer recurrence, payer payee overlap.
