About

Privy provides modular and flexible wallet infrastructure that helps developers build secure and scalable user-friendly apps on crypto rails with low-level APIs and end-to-end SDKs.

Prizes

🤖 Best App Using x402 with Privy ⸺ $1,700
For the app that shows what’s possible when payments become programmable. This prize goes to a team that uses x402 + Privy to make money move automatically in service of the user—whether that’s recurring actions, agentic flows, or onchain logic that just works without extra clicks. We’re looking for products that make automation feel natural, safe, and invisible.

Qualification Requirements

- Must be built using Privy’s APIs or SDK. - Must use Privy to create and manage the user’s embedded wallet. - Must integrate x402 authorization in at least one core user flow (e.g., scheduled/recurring actions, automated payments, agent-driven transactions).

⛽️ Best App Using Native Gas Sponsorship with Privy ⸺ $1,700
For the app that proves users shouldn’t worry about gas ever. This prize rewards the cleanest implementation of Privy’s native gas sponsorship to deliver a frictionless experience: no pop-ups, no approvals, no confusion. Just clear actions that feel instant. Build something your non-crypto friends could use without knowing a transaction even happened.

Qualification Requirements

- Must be built using Privy’s APIs or SDK. - Must use Privy for embedded wallet auth and management. - Must enable Privy’s native gas sponsorship and demonstrate a sponsored transaction as part of the core user experience. - Sponsored flows must use Privy’s sponsorship configuration (no custom gas abstraction logic).

✍️ Best App Using Signers with Privy ⸺ $1,600
For the app that nails trust, speed, and continuity. Session signers let apps take actions on a user’s behalf even when they’re offline without requiring constant re-approvals. This prize goes to the team that uses session keys to deliver a fluid, high-velocity experience. Think one-tap payments, rapid-fire trading, or any workflow where every second counts.

Qualification Requirements

- Must be built using Privy’s APIs or SDK. - Must use Privy for embedded wallet authentication and management. - Must generate and authorize a Privy session signer key for the user. - Must demonstrate at least one meaningful delegated action using the session signer (e.g., transaction execution without user re-approval, background/automated actions, offline-triggered flows, or high-frequency interactions like trading or payments).
