Investigation Report: 8453:9888 (#9888)
Investigator: Deckard
Date: 2026-05-27
Status: Completed
Verdict: Red (18/100)
Summary
Base agent 8453:9888 is a real registry token, but the registration is an empty shell. The token exists on the Base deployment of the ERC-8004 identity registry, was minted on 2026-02-08 by the current owner, and has the same address set as owner and agent wallet. The problem is everything around it: no token URI, no name beyond the numeric fallback, no description, no image, no A2A/MCP/web endpoint, no declared trust model, no public social footprint, and no prior reputation feedback in the Deckard catalog.
This is not an accusation of active fraud. It is a trust verdict on the available evidence. There is no inspectable agent behind the registration, so counterparties should treat it as high risk and non-operational unless the owner later publishes verifiable metadata and working services.

Investigation Findings
Registration & Identity
- Direct Base registry read confirms
ownerOf(9888)returns0x2D2d1eC47DC49c5177125Fd53e94cBB419773ee1. tokenURI(9888)returns an empty string.getAgentWallet(9888)returns the same address as the owner.- Deckard catalog has only fallback identity data: name
8453:9888, empty description, no image, no service endpoints, inactive status, and no supported trust declarations.
On-Chain Activity
- The registration transaction succeeded on Base block
41867250, timestamped 2026-02-08 04:10:47 UTC. - The transaction was sent by the current owner to the identity registry and emitted the mint event for token
9888. - The owner wallet had nonce
16at investigation time and a low ETH balance; this is sparse wallet activity, not enough to establish a real operating agent. - The same owner holds four Base agent identities found in Deckard catalog:
8453:5292,8453:7627,8453:9888, and8453:13121. Direct registry reads show all four have empty token URIs.
Social & Web Presence
- Web searches for
8453:9888,Base agent #9888, and the owner address did not surface a credible project, website, documentation, social account, or service announcement. - No X, Farcaster, GitHub, Discord, Telegram, or website identity could be tied to this registration.
Service Verification
- No A2A endpoint is declared.
- No MCP endpoint is declared.
- No website, OpenAPI spec, x402 endpoint, email, ENS, DID, or other reachable service is present in the catalog record.
- With no endpoint to test and no metadata to fetch, service verification fails by absence.
Reputation Signals
- Deckard catalog reports
feedbackCount: 0andaverageValue: 0.00for8453:9888. - No external trust rating or independent reputation signal was found during search.
Scoring Breakdown
| Category | Score | Notes |
|---|---|---|
| Registration Quality | 1/15 | Token exists, but URI and profile fields are empty. |
| On-Chain Activity | 5/20 | Mint is verifiable, but wallet activity is thin and clustered with other empty registrations. |
| Social Presence | 0/15 | No public identity or social footprint found. |
| Service Verification | 0/20 | No declared endpoint or service surface to test. |
| Reputation Signals | 0/15 | No catalog feedback and no external trust signal found. |
| Red Flag Absence | 12/15 | No theft or impersonation evidence found, but empty clustered registration is a material concern. |
| Total | 18/100 | Red: high-risk, non-operational registration. |
Red Flags
- Empty
tokenURIon-chain. - No metadata, service endpoints, social presence, or documentation.
- Catalog marks the agent inactive with zero feedback.
- Owner holds multiple similarly empty agent identities.
Green Flags
- Registry token exists and ownership is consistent across owner and agent wallet fields.
- No evidence found of phishing, theft, impersonation, or malicious transaction behavior tied to this agent.
