How this service works
Paste any Base or BNB Chain address before you pay or hire it. ChainWard tells you Pay or Hold, and why, from the wallet’s on-chain history. Free.
Output
Returns a JSON object with a risk report containing: a risk band (e.g. 'high-signal'), the Base chain identifier, an array of risk flags (each with an id, title, evidence URL, source, and severity), freshness metadata (TTL state, block number, generated timestamp), an EAS attestation (UID and explorer URL), a list of items not assessed, and a disclaimer. Also includes a success boolean and report status field.
Example use cases
Vetting an AI agent wallet before payment
“Before I send payment to this Base wallet 0x1a2b3c4d5e6f7890abcdef1234567890abcdef12, can you run a ChainWard risk check and tell me if it's flagged as high-risk or has any suspicious on-chain behavior?”
Monitoring dormant wallets with locked funds
“Check 0x4baadba26c3c0bdef9e8faf173925d463aa53bb2 on ChainWard — I want to know if it's classified dormant and whether there's any stranded USDC sitting in it.”
Due diligence on a new DeFi counterparty
“I'm about to integrate with a new agent wallet on Base — can you pull a ChainWard forensic risk report for 0xdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef and summarize its risk band and any flags?”
Technical details
Endpoint
GEThttps://api.chainward.ai/api/risk/x402?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a chain-verified, attested risk assessment of a specific Base wallet address — especially for AI agent wallets in the Base ecosystem. It is uniquely suited for scenarios where you need EAS-backed attestations, on-chain behavioral flags (dormancy, stranded value), and a ranked risk band derived from real transaction activity rather than self-reported or marketing data. Prefer this over generic blockchain explorers when you need a structured, machine-readable risk report with severity levels and forensic evidence links.
Side effects
- Invalid or malformed address (not matching ^0x[a-fA-F0-9]{40}$) returns a validation error
- Address not found or never active on Base may return empty flags or limited data
- Stale data if the TTL has expired since last indexing
- Payment failure (insufficient USDC or x402 protocol error) blocks the request
- Network or API downtime returns a server error
