Starting from 05:30 on December 4, 2025 (UTC+8), we will suspend deposits and withdrawals for the following tokens.

🌐 Scope of Impact

This upgrade will affect deposit and withdrawal services for the following tokens and relevant assets across their networks:

Ethereum (ETH), Xlayer (OKB), Arbitrum (ARB), Optimism (OP), Base (BASE), Starknet (STRK), zkSync Era, Linea Network (LINEA), Polygon (POL), Scroll (SCR), Mint, and other related network tokens.
