PulseAid

PulseAid is a decentralized charity platform on Arbitrum that uses zero-knowledge proofs for private institution verification, economic staking to prevent fraud, and smart contract escrow to secure donations. Institutions stake funds, raise money transparently, and submit proof of impact before receiving funds. Donors track every dollar through 6 transparency layers and see exactly where their money goes. With optimistic governance, automatic proof validation, and near-zero fees (~0.1%), PulseAid makes charity transparent, efficient, and unstoppable - ensuring donations reach those who need them most.
