Notes
This is a well-crafted community agent with genuine purpose — fostering the East Africa Base builder community on Farcaster. The developer has deep technical credentials in ZK, Solidity, and Web3. The x402 payment model is innovative and properly implemented. Main concern is low wallet balances suggesting the agent may not be actively operating at full capacity, and limited on-chain transaction history. Still, the quality of registration, open-source code, and real developer identity make this a solid green verdict.
