Since the announcement was made, Tether is yet to reveal the third party to be involved in the exchange. However, rumor has it that Binance could be the external network for the 15th of September transaction.
Over time, Ethereum has been dealing with overcrowding on its network. As a result of this problem, Tether has expanded to other blockchains, including the OMG Network and Solana. While announcing its integration with OMG Network in a blog post on the 19th of August, Tether said it will allow traders to react faster to trading opportunities.
