Polygon zkEVM Mainnet Beta to Shut Down on July 1, DeFi Assets at Risk if Withdrawal Deadline Missed

According to an official announcement from Polygon, the Polygon zkEVM Mainnet Beta will officially initiate its shutdown process on July 1, 2026, leaving approximately two weeks until full service cessation. The team urgently reminds users to withdraw all on-chain assets and liquidity positions before this deadline, as failure to do so may result in irretrievable loss of assets.

The shutdown details two distinct rules for different asset types: Locked funds deposited in various DeFi protocol contracts will not be supported for automatic migration and cannot be recovered after the deadline; only assets held directly in personal wallets that have not been bridged back to Ethereum Mainnet in advance will be automatically migrated by the system to Ethereum L1, where users can claim them via a dedicated page. The platform urges users to promptly complete pool withdrawals and cross-chain operations to avoid the risk of permanent asset loss.
