Within hours after the hard fork was implemented, Ethereum exchanges have allowed users to once again deposit and withdraw Ether.
Top exchanges Poloniex, GDAX, and Gemini went to Twitter to notify their users of the successful development. These exchanges explained they would pause ETH/DAO deposits and withdrawals in order to prepare their operations for security purposes in light of the hard fork. Their trading platforms were not affected during this process.
