Starting at 04:00 AM UTC (12:00 PM UTC+8) on October 26th, 2021, Binance will begin blocking all access and communication from Singapore. To avoid losing access to your connected Binance account on Fireblocks past this date, you must whitelist the IP address 18.133.153.74 immediately. This new IP address must be added to the original IP address you previously whitelisted.
We will switch to the new IP address on Monday, October 25th at 12:00 PM UTC. You should not remove the original IP address (52.76.208.129) until after this date and time.
Refer to the Binance account article for more information on how to add a new whitelisted IP address to your Binance API key.
