ZKPay

Overview:

ZKPay is a fast-withdrawal bridge on the Aztec Network, enabling users to securely and privately transfer assets like ETH, DAI, USDT, and USDC between Aztec’s Layer 2 and various EVM chains (e.g., Ethereum, Polygon). Unlike standard bridges that take hours, ZKPay completes these withdrawals in seconds, offering seamless, zk-proof–powered privacy transfers.

Designed and deployed zk-powered bridge contracts enabling near-instant withdrawals (~seconds) from Aztec L2, bypassing typical ~6‑hour finality delays.Enabled support for ETH, DAI, USDT, and USDC across both Ethereum mainnet and Polygon, expanding usability and accessibility.Introduced a ZK badge NFT system—users who deposit ≥ 0.1 ETH and interact 3 times earn badges, unlocking future fee discounts.Incorporated a swap feature in v2.0.0 (currently in VIP beta), allowing private swapping of L2 assets before withdrawal.

Outcome:

ZKPay has significantly improved user experience within the Aztec ecosystem, reducing withdrawal times from hours to seconds while preserving transaction privacy. Its badge-based incentive model drives early engagement and deeper platform usage.
