Stellar development foundation’s validator nodes temporarily stopped working today at 1PM PST which means transactions could not be done on Stellar network.
This includes public Horizon API instances as well which are used by most of Stellar decentralized exchanges including StellarTerm and StellarPort.
This means you cannot do any trades at all until SDF validator nodes and public Horizon APIs come online again. Most of the small projects built around Stellar, including some Stellar wallets, make use of SDF’s validator nodes instead of running their own validator nodes.
So, if you are using a website or an app that makes use of SDF nodes, you are out of luck and you will have to wait for the Tier 1 validators to again become available to process transactions.
This does not mean that Stellar network is not working. Any app or portal that is running its own validator nodes, for instance, Coinqvest is able to process transactions. Also, any app running its own Horizon instance is able to perform transactions just fine. This includes SDF’s backed Solar wallet as well.
However, major cryptocurrency exchanges, including Binance, are not accepting deposits or performing withdrawals.
Right now, the SDF engineers are still working on fixing this issue. There is no ETA for a fix, so if you were thinking of cashing out your XLM for USD or BTC, you would either have to wait or use a wallet that runs its own Stellar node. One such example is Lobstr wallet.
