Build a consumer-facing application where users can send, receive, or manage payments privately on public EVM chains using the Unlink SDK. Think private payroll, peer-to-peer transfers, merchant checkout, tipping, or subscription payments — any flow where sender and/or receiver privacy matters. Unlink handles the ZK proofs and relaying — you focus on the UX. We want to see apps that make private payments feel as simple as Venmo / Revolut / Paypal.

Use the Unlink SDK in a way we didn’t expect. Surprise us! The winning project will demonstrate a novel use of private transactions beyond simple payments. Judging favors originality and real-world relevance over polish.

Add privacy to a DeFi action using the Unlink SDK. Swap, lend, provide liquidity, or claim yield — without exposing your wallet activity on-chain. Today anyone can see what you’re doing and how much you hold. Show us what DeFi looks like when that’s no longer the case. Judged on how smooth the experience feels and how real the privacy benefit is.
