cross-chain smart contracts connecting Bitcoin, Ethereum, and other networks. The protocol has been flagged by community investigators and crypto-security observers following a premeditated $334,000 exploit of its GatewayEVM smart contract in April 2026, which the team's own earlier bug-bounty review had dismissed as intended behavior. Additional concerns include a controversial airdrop policy that rewarded sybil actors, persistent token unlock sell pressure, and structural centralization risks inherent to its Threshold Signature Scheme validator design.","timeline":[{"date":"2021-01-01","event":"ZetaChain founded by Ankur Nandwani and Charlie Pyle in San Francisco.","source":"Crunchbase / CBInsights","source_url":"https://www.crunchbase.com/organization/zetachain"},{"date":"2023-08-01","event":"ZetaChain raises $27 million in Series A from Jane Street Capital, Blockchain.com, Sky9, and others.","source":"TechCrunch","source_url":"https://techcrunch.com/2023/11/16/zetachain-bitcoin-trading/"},{"date":"2023-08-20","event":"Snapshot taken for genesis airdrop eligibility across ZetaLabs testnet participants.","source":"ZetaChain Blog","source_url":"https://www.zetachain.com/blog/the-zetalabs-airdrop-pre-claim"},{"date":"2024-01-01","event":"ZetaChain Mainnet Beta launches; over 900,000 users and 8 million transactions reported in first week.","source":"ZetaChain Blog","source_url":"https://www.zetachain.com/blog/announcing-zetachain-mainnet-beta-launch"},{"date":"2024-02-01","event":"ZETA token begins trading.
