What Is ZetaChain?
ZetaChain is a novel Layer 1 blockchain launched in September 2021. It stands out by offering universal smart contract functionality across all blockchains, allowing developers and users to send tokens, NFTs, and arbitrary messages between chains—without relying on wrapped assets or trust-minimized bridges.
This omnichain capability makes ZetaChain a powerful solution for true cross-chain interoperability, addressing long-standing fragmentation issues in the decentralized ecosystem.
Founded by early Coinbase employees and creators of Basic Attention Token (BAT), ZetaChain brings strong technical expertise and industry credibility. The project has already secured significant funding, including a $27 million equity round in August 2025 from top-tier investors such as Blockchain.com, Human Capital, VY Capital, Sky9 Capital, and Jane Street Capital.
ZetaChain's testnet has progressed to the "Athens-3" phase, with the mainnet expected to launch in Q4 2025. This timeline positions it as one of the most anticipated blockchain rollouts of the year.

Frequently Asked Questions (FAQ)
Q: Do I need real funds to participate?
A: No. All tasks occur on ZetaChain’s testnet. You’ll use free test tokens, so there’s no financial risk involved.
Q: Why isn’t my task showing as completed in OKX?
A: Some verifications take time. Wait several minutes after completing each step before checking back. Avoid refreshing repeatedly.
Q: Can I use MetaMask instead of OKX Wallet?
A: While you can interact with DApps via MetaMask on desktop, only OKX Web3 Wallet allows you to claim rewards and verify completion for this campaign.
