Could you build this?
Partial An agent interface that triggers payment functions can be vibe-coded quickly, but a secure, non-custodial wallet infrastructure with autonomous spending limits requires rigorous cryptographic and financial security engineering.
What it would actually take: The architecture relies on smart contracts or account abstraction (ERC-4337) on EVM/Solana or Lightning rails, paired with local client signing tools that enforce cryptographically verified spending caps and merchant whitelists. The critical challenge is preventing agent loop drains, race conditions, and key leakage while maintaining autonomous execution without human intervention. This requires deep smart contract security, cryptographic key management, and financial transaction settlement expertise.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
