If you use an exchange (such as Coinbase, Kraken, or Binance), a web wallet service (such as Metamask, MyCrypto, or MyEtherWallet), a mobile wallet service (such as Coinbase Wallet, Status.im, or Trust Wallet), or a hardware wallet (such as Ledger, Trezor, or KeepKey) you do not need to do anything unless you are informed to take additional steps by your exchange or wallet service.

Crypto.com is supporting the upcoming Ethereum Berlin Upgrade, which will take place on 15 April 2021. To ensure the safety of users’ funds during and after the upgrade, we will suspend deposits and withdrawals of ETH and all ERC20 tokens (e.g. USDT, USDC, etc.) in the Crypto.com App, Exchange, and DeFi Wallet roughly 1 hour before the target block height 12244000.
After months and months of planning, Berlin is finally here! The upgrade, which follows the Istanbul and Muir Glacier upgrades, is scheduled to go live on the Ethereum mainnet at block 12 244 000. We expect this to happen around Wednesday, April 14, 2021, but because of block time variability, the exact date may change.
Prior to being deployed on mainnet, the upgrade will go live on the Ropsten, Goerli, and Rinkeby testnets. The entire release schedule is as follows:

Ethereum node operators should upgrade their nodes prior to the fork block on the networks they want to participate in. Due to block time variability, it is recommended to update several days before the expected date. See the section below for the appropriate client versions to upgrade to.
