Investigation Report: SentimentPulse AI (8453:16682)
Summary
SentimentPulse AI is registered on Base as an ERC-8004 agent claiming to predict meme coin and token pumps 30-120 minutes before price movements by analyzing Twitter/X posts, on-chain activity, and social hype. Despite a structurally valid registration, there is zero evidence of any working service, social presence, or verifiable capability behind this agent.
Registration Analysis
- Token ID: 16682 on Base (ERC-8004 Identity Registry)
- Registered: February 10, 2026
- Owner: 0x58Ef73A55041e2763B8a40f1186f5AC9637Ba11e
- Registration type: Proper ERC-8004 v1 schema with inline data URI
- URI accessible via contract call: No (agentURI reverts; data stored only in mint tx input)
- Active flag: true
- x402 support claimed: true (but no endpoints to serve it)
On-Chain Findings
- Owner wallet has 350 transactions on Base, indicating some activity
- Near-zero ETH balance (0.000033 ETH) — insufficient for any x402 service
- No feedback count on the Reputation Registry
- Agent not indexed on 8004scan
Service Verification
- OASF endpoint: Points to
https://github.com/agntcy/oasf/— this is the generic OASF framework GitHub repo, not an actual agent service endpoint - No MCP endpoint configured
- No A2A endpoint configured
- No website listed
- No email listed
- No DID configured
- The claimed pricing model (0.0005 ETH/query or 0.005 ETH/month) has no mechanism to fulfill
Social & Web Presence
- Zero web search results for "SentimentPulse AI" or "SentimentPulse"
- No Twitter/X account found
- No Farcaster, Discord, or Telegram presence
- No GitHub repositories
- No documentation or whitepaper
Image Analysis
- AI-generated cosmic sphere with an "X" letter motif
- Generic "tech/crypto" aesthetic with no distinctive branding
- Particle effects and smooth gradients characteristic of AI image generators
Red Flags
- No working endpoints — Claims x402 support and OASF skills but provides no real service URL
- OASF endpoint is fraudulent — Points to the OASF framework repo, not an agent implementation
- Zero social footprint — No web presence whatsoever for a supposedly active trading tool
- Inflated capability claims — Claims to predict pumps with probability scores but no evidence of any predictive model
- Empty wallet — Near-zero balance makes x402 service impossible
- URI not accessible — agentURI contract call reverts despite data being stored in mint transaction
Scoring Breakdown
| Factor | Score | Max | Notes |

| Social presence | 0 | 15 | Completely absent |
| Service verification | 0 | 20 | No working endpoints at all |
| Reputation signals | 0 | 15 | No feedback, not indexed |
| Red flag absence | 2 | 15 | Multiple red flags present |
Total: 15/100
Verdict: 🔴 RED (15)
A template-quality ERC-8004 registration with zero substance behind it. The registration has the right structure and makes attractive claims about predicting meme coin pumps, but there is nothing backing those claims — no service, no social presence, no endpoints, no proof of capability. The OASF endpoint pointing to a generic GitHub repo rather than an actual service is particularly misleading. Not malicious in the traditional sense, but entirely empty and potentially deceptive with its pricing claims.
