We’ll handle your security in case of emergency and fraud, and you can deposit, store, trade, transfer your open.EOS tokens before, during and after the official EOS release moment, without worrying about your ETH wallet, private keys or transferring.
That makes OpenLedger DEX the natural choice to store and trade your EOS tokens safely and securely.
If you have an OpenLedger DEX account, you can just log in and trade as normal.
と言っているので、大丈夫です。
というより、現時点ではもう既にOpenledgerからEOSは引き出せないようになっているはずです。Openledgerが出しているスケジュールは以下の通りです。
1. Starting from May 31 (16:00:00 UTC), OpenLedger DEX will suspend all the EOS and eosDAC deposits and withdrawals.
2. On June 1, EOS and eosDAC trading and transfers will be temporarily unavailable due to technical works from 13:00:00 UTC to 16:00:00 UTC.
3. After the upgrade, the mainnet token swap will be implemented.
4. We will announce later on the exact date when all the deposit and withdrawal operations will resume.
