Exchanges Halt Transactions for GRC

Mandatory Releases

As many of you that run Gridcoin wallets have noticed, or hopefully will see now, there was a mandatory update rolled out on the 22nd of August. Since then there has been another Mandatory Update Released. We are now at the latest mandatory release of 3.6.0.2.
You can find a Release note and the source code on the Gridcoin GitHub Repository.

Exchanges halting during this process

An update for exchanges requires at least two weeks’ notice. On August 21st, the day before the new Mandatory was released, all exchanges and services were notified of this. During the process of updating the wallets and rolling out the new mandatory version, most exchanges have halted their wallets.
We’ve had confirmations of the following exchanges or services:

• Cointopay
• C-CEX
• Coinpayments
• Cryptogames
• OpenLedger
• HolyTransactions

Notified exchanges or services without confirmation responses
