Devryno Base USDC microtools - share kit

One-line pitch:
No-account Base USDC microtools: transaction receipts, recent wallet statements, and merchant feed audits paid per use with tiny USDC payments.

Short post:
I am building Devryno as a shelf of tiny wallet-native utilities. No account, no subscription: send a small Base USDC payment, paste the payment hash, and get focused JSON back. Current tools: Base USDC Receipt (0.10 USDC), Base USDC Wallet Statement (0.25 USDC), and Merchant Feed Audit (0.25 USDC). Useful for crypto freelancers, DAO ops, bounty/admin records, micro-sellers, commerce operators, and agents that need public evidence before continuing a workflow.
