How HUSH Works

Four layers of privacy, one seamless experience

Umbra Protocol

Stealth Deposits

Powered by Umbra SDK, every deposit is routed to a one-time stealth address. Your wallet is never linked to the donation on-chain.

MagicBlock PER

Private Ephemeral Rollups

Grant disbursements execute inside MagicBlock's ephemeral rollup. Sub-second finality with full Solana security. Zero MEV exposure.

AI-Powered

AI Yield Agent

Your shielded balance earns while it waits. An on-chain AI agent continuously rebalances across Kamino, Marginfi, and Solend for optimal APY.

IRS Compliant

ZK-Tax-Receipts

Prove charitable deductions to the IRS without revealing your identity. A ZK proof anchored on-chain satisfies §170 documentation requirements.

Selective Disclosure

Viewing Key Privacy

You control disclosure. Share a viewing key with your accountant for audit access — while keeping the rest of your on-chain history completely private.

More Impact

Yield on Impact

USDC deposited to HUSH generates yield before it's granted. Every dollar gives more than a dollar. Yield accrues to your next grant automatically.

Process

Four steps to silent philanthropy

Connect & Deposit

Connect your Phantom or Solflare wallet. USDC is routed to a stealth address — no on-chain link to your identity.

Earn Yield

Your shielded balance is deployed to the highest-APY DeFi protocols by the on-chain AI agent. Watch it grow.

Advise a Grant

Select a charity from the curated list or enter any wallet address. The grant executes privately inside MagicBlock PER.

Generate Receipt

Use your viewing key to generate a ZK-Tax-Receipt. Share with your accountant. Keep everything else private.
