For crypto infrastructure founders

Cut the noise without cutting off real people.

Founders in crypto infrastructure are targeted by cold outreach, shilling and phishing. zkBounce lets you set a bond that honest senders get back in full.

Join the beta as a founder

On Base, in USDC

One chain and one stablecoin. No new token to hold or trust.

No custody

zkBounce does not hold your funds.

Private settlement

Zero-knowledge proofs settle outcomes without exposing identities.

Early stage: Phase 0 feasibility, pre-beta, contracts unaudited.

These are our public commitments. They are design rules, not marketing.

  • No tokenWe will not sell, airdrop or announce a token.
  • No exchange, no custodyzkBounce does not hold user funds.
  • Base onlyNo custom Layer 1.
  • A bond, not a feeDelivered and ignored mail both refund the sender in full.
  • Payment before emailThe bond is posted before the message is sent. No auto-responders.
  • No admin backdoorDesign goal: no admin key can move user bonds from the vault.
  • Private by designNo server-side matching. Email addresses and message content are never committed on-chain.

What we have not done yet

The smart contracts have not been audited. We have no published Phase 0 results. We will say so here until that changes.

Code will be published openly. A link to the repository will appear here when it is public.

Long-term, we think of zkBounce as a verified consent and attention settlement layer. Email comes first.

Contracts are unaudited. Nothing on this page is a promise of features or dates.
