SOLANA DEVNET

Verifiable Care
On-Chain. Forever.

Privacy-first infrastructure for animal rescue networks in Latin America. Every care event โ€” hashed, attested, and minted on Solana.

The Problem

No proof of care

Animal rescue foundations in LATAM cannot prove to donors that funds reached the right animal. Vaccination records are lost. Care events are unverifiable. Trust breaks down.

The Solution

Verifiable Care Receipts

Every animal care event is hashed with SHA-256, attested by a verified operator, and minted as an NFT on Solana. Immutable. Public. Verifiable by anyone โ€” without exposing private data.
