Tracks and Bounties
Best Web3 Onboarding UX using ZKsync Smart Sign-On (SSO) SDK
Signing every tx, dealing with popups, & relying on third-party wallets are some of the worst parts of crypto UX. Build with ZKSync SSO SDK to bring Web2-like UX to your app.
Build an AI Agent on Abstract Chain, Lens, or Sophon
Launch an AI agent on Abstract Chain, Lens, or Sophon ZKsync Era. Your agent should interact with smart contracts, execute onchain actions, or automate tasks. The best usecase or MVP wins!
Best Consumer App Deployed on Abstract Chain, Lens, or Sophon
Build the next generation of products on ZKsync Elastic Network chains to onboard millions of users.
ZK is the Endgame
Build ZK apps on ZKsync Era.
The Tech
What you need to know
ZK technology powers the Elastic Network
A fully realized and integrated L2 ecosystem with shared liquidity and users. The Elastic Network is designed to scale Ethereum without compromising decentralization or security.
ZK Stack
A modular, open source framework used to build ZK chains that are fullv EVM compatible.
Scalability
ZK-rollups bundle thousands of transactions into a single proof, massively increasing the number of transactions Ethereum can handle.
Improved security
ZK ensures transactions are cryptographically valid, enhancing Ethereum's security guarantees.
Performance (high throughput)
Processing transactions off-chain and verifying them with ZK proofs lets networks achieve lightning-fast speeds. ZKsync is aiming for 10,000 TPS in 2025.
Data integrity + privacy
ZK enables users to protect their transaction data while still proving it's valid - a pivotal step for privacy-conscious dApps.
ZKEVM compatibility
By supporting Ethereum-native tools, developers can easily migrate or build applications without friction. It's Ethereum-first while embracing ZK-native innovation.
Low gas fees
With fewer transactions on Ethereum's mainnet, gas fees drop significantly. The current roadmap targets gas fees as low as $0.0001 by end 2025.
