Review and Judging

July 21st 9:30am PST

Winner’s Project Demo/Closing Ceremony


  • Must use Omnichain Smart Contracts/deploy on zEVM and/or Connector API (cross-chain messaging).
  • Projects will be evaluated on:
    • Use of ZetaChain-specific APIs/utility (omnichain smart contracts, ZRC-20, and/or messaging).
    • Potential impact: how big is the need or market for this? Could this become a sustainable application or business?
    • Creativity/novelty: Has this not been done before? What innovation is this introducing to the ecosystem? Why is now the right time for this?
    • Technical expertise/complexity: Is this introducing any new mechanism or technology in a new way? What has prevented this from being created to-date? Is there some technical moat?

Entry is open for ALL projects using or building on ZetaChain. Projects that leverage certain omnichain features will be judged with higher priority for prizes.

To confirm that your project fulfills the requirements above, please provide a short description and evidence of integration in your BUIDL for inspection. The description should explain the usage of the feature(s) or chain. The evidence may include addresses and/or actual contracts deployed.

About ZetaChain

ZetaChain is the foundational, public blockchain enabling omnichain, generic smart contracts and messaging between any blockchain. It solves the problems of “cross-chain” and “multi-chain” and opens the crypto and global financial ecosystem to anyone. ZetaChain supports a truly fluid, multi-chain crypto ecosystem, where users and developers can move between and appreciate the benefits of any blockchain: payments, DeFi, liquidity, games, art, social graphs, performance, security, privacy, and so on. The founding team has previously co-founded Basic Attention Token, has strong crypto product experience since 2013 and academia research backgrounds in top ranked US universities.

Key features

Decentralized and public: ZetaChain is a decentralized and public blockchain network. It is built on Cosmos SDK and Tendermint Consensus. While many cross-chain solutions like bridges have varying, often centralized trust models that have a track record for being susceptible to exploits and hacks, ZetaChain is a Proof-of-Stake blockchain, where all transactions and activity on the platform -- even cross-chain transactions -- are fully transparent, verifiable, and function in a trust-minimized manner.

Hyper-connected nodes: ZetaChain's nodes have observers that monitor transactions on every connected chain. Through ZetaChain's TSS architecture, the network can sign and verify transactions on every connected chain as a wallet can. By being able to read and write to connected chains in a secure, decentralized manner, these hyper-connected nodes provide a seamless omnichain environment for developers to build novel and powerful cross-chain applications on top of.

Omnichain message passing: A developer can pass messages (data + value) between chains and layers with simple function calls. Through message passing, a dApp developer can build powerful cross-chain applications by simply implementing a few functions within their existing smart contracts.

Omnichain smart contracts: Smart contracts can be deployed natively on ZetaChain that can read/write to connected chains. ZetaChain is the only public blockchain to support smart contracts with this capability, enabling a new paradigm of app development.  

Managed external assets: ZetaChain's network and dApps built on top of ZetaChain can manage assets and vaults of external connected chains. This allows assets on any chain to be managed just as a smart contract on a single chain can manage assets on its respective chain. A dApp on ZetaChain can thus orchestrate and bring smart contract logic to any connected chain. This property applies to all chains, including non-smart-contract chains, like Bitcoin and Dogecoin.
