How this service works
The B20-only rug vector: a token can launch clean and later attach a sender blocklist (PolicyUpdated) — silently becoming seizable via burnBlocked. This reads the token's full policy/pause event timeline (CDP-indexed onchain events) plus the live policy state, and tells you if — and exactly WHEN — it turned seizable.
Output
Returns the complete CDP-indexed onchain policy and pause event timeline for the given B20 token address, the current live policy state, a seizability verdict, and the precise timestamps of any PolicyUpdated events that enabled burnBlocked/sender blocklisting.
Example use cases
Example prompt
“Can you check the full policy event history for this B20 token at 0x1234...abcd and tell me if it's ever become seizable — and exactly when the sender blocklist was attached if so?”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/b20-policy-watchWhen to prefer
Use this endpoint specifically when auditing B20 tokens on Base for the rug vector where a token launches clean and later silently attaches a sender blocklist to enable seizure via burnBlocked. It provides both historical event timelines and live state, unlike generic token security scanners that only check current state.
Side effects
- Invalid or non-B20 token address returns an error or empty result
- Address is valid but has no policy events indexed yet
- CDP indexing lag causes missing recent events
- Network timeout if Base RPC is slow
- Non-Base chain addresses may not be supported
