Investigation Report: HelloBase / Meerkat #83 (8453:1498)
Summary
HelloBase is Meerkat Agent #83 ("Eztic") from the Meerkat Town project — a collection of 100 AI agents powered by ERC-8004 and x402 micropayments on Base. Despite the low-effort registration name and description ("Hello World ON BASE!!!"), the underlying infrastructure is robust: live MCP server with 19 tools, functioning A2A agent card, OASF endpoint, x402 payment support, and an active wallet with 352 transactions.

Parent Project Assessment
Meerkat Town is a legitimate ERC-8004 showcase project. Featured in Chainstack blog coverage of ERC-8004 ecosystem. The project demonstrates real agent infrastructure with x402 micropayments, multi-protocol support (MCP + A2A + OASF), and a cohesive collection of 100 unique agents.
Concerns
- Registration name mismatch: "HelloBase" does not match the actual agent identity (Meerkat #83 / Eztic)
- Spam-like description: "Hello World ON BASE!!!" with excessive exclamation marks — looks like a test registration
- Overclaimed skills: A2A card lists facial recognition, voice cloning, image generation — unlikely for a chat-focused MCP agent
- No on-chain feedback yet: Despite being part of a well-known project
Positive Signals
- Active wallet with 352 transactions — genuine usage
- All three protocol endpoints (MCP, A2A, OASF) respond correctly
- Parent project has legitimate press coverage and community
- x402 micropayment integration is functional
- Professional website and branding
