South Korean cryptocurrency exchange Upbit has temporarily suspended ZETA deposits and withdrawals, effective immediately from the time of its notice, citing delays in block production on the Zetachain network. The halt is intended to prevent stuck transactions, failed transfers or potential losses while the network experiences congestion and slower block generation. ZETA trading may continue on Upbit, although the exchange has not confirmed specific trading availability. Users can retain their existing balances on the platform but cannot transfer tokens to external wallets or other exchanges, limiting liquidity and arbitrage opportunities. Zetachain is a blockchain platform designed for cross-chain interoperability, or connections between different blockchain networks. The source notes that the network has faced periodic issues as it scales, with delayed block production potentially linked to validator performance, network upgrades or unexpected technical glitches. Upbit has not set a resumption date and will reopen deposits and withdrawals once block production returns to normal. Users with pending transactions should monitor their status, avoid new transfers until services resume and follow Upbit’s official announcements. Traders should also exercise caution because the suspension may contribute to price volatility. The halt is presented as a precautionary measure reflecting operational and security risks tied to network dependencies.
