United States-based cryptocurrency exchange Coinbase has announced it will be temporarily suspending certain token deposits and withdrawals when Ethereum’s core developers transition the blockchain to proof-of-stake, or PoS.

In a Tuesday blog post, Coinbase product manager Armin Rezaiean-Asel said that during the Merge event, the crypto exchange will “briefly pause” deposits and withdrawals of Ether (ETH) and ERC-20 tokens “as a precautionary measure” to handle the migration. The exchange also warned users against scammers offering ETH2 tokens, saying crypto users did not need to take additional action to receive staked ETH prior to the Merge.
