Import an ETH wallet

Keystore: In the Ethereum wallet, the private key and public key will be encrypted as the Keystore with the password you set when creating the wallet. So if you want to import the wallet in this way, you can enter the Keystore by scanning the QR code and entering the corresponding password. Please note that the corresponding password is the one when you create the wallet. Private key: Private key is generated by a long random number. Holding a private key is holding assets. In this way, you can enter the phrase or scan the QR code of the private key, and then set a new password. Mnemonic: Mnemonic code was proposed by the BIP 39 proposal. The purpose is to randomly generate 12 to 24 words that are easy to remember. So when you remember the Mnemonic, it is equal to remember the private key. If you choose this way to import, please enter the Mnemonic separated by spaces and pay attention to the letter case.

Backup your ETH Wallet

After creating a new ETH wallet, you can choose back up now or later. We highly recommend you to back up the Mnemonic immediately when asked. The system will randomly generate 12 words, please write these down on a piece of paper and store them safely offline. If you do not back up immediately, you also can backup anytime after that however you are strongly advised against this approach. On the other hand, if you import the existing ETH wallet to O3 by private key or Keystore, the Mnemonic will not display on the wallet manage page. This is because the phrase was not originally generated by O3 wallet.

Transfer ETH and other ERC-20 tokens

On the transfer page, you can enter the receipt ERC-20 address which started from ‘0x’ by importing from your address book or scanning QR code. Next column, choose the ERC-20 assets and set the amount you want to send. In addition, the miner fee is customized. You can decide how much Gas price you want to add. The higher the miner fee, the faster the transfer speed. After checking the payment detail, you can confirm the transaction by password, Touch ID, or Face ID.

In addition, if you send more than one transaction continuously, there may still be some transactions that have yet to be confirmed by the network. The system window will pop up and ask if you would like to speed up the previous transaction (by adding some funds to the mining fee) or continue sending the current transaction.

Accelerate or Cancel your transaction

In general, the speed of transaction confirmation depends on the amount of the mining fee and to a lesser extent, the current state of the ETH network. The higher the fee you assign to the transaction, the quicker the confirmation process will be.

What if the transaction stuck? Don’t worry, you can accelerate the transaction after sending by clicking ‘Speed up’ on the transaction details page within the wallet. When a user initiates this feature, O3 Wallet will automatically calculate the best miner fee based on network conditions at that moment. This makes the process very simple and convenient.

In addition to the ‘Speed Up’ feature, O3 has also implemented the option for users to cancel their transaction altogether. If you wish to terminate the transaction, simply click the ‘Cancel’ button.

Of course, only transactions that have yet to be confirmed (still in process) can be canceled. When you cancel the transaction, your wallet actually overwrites the unwanted transaction with a zero amount ETH send to yourself. Due to this, miner fee is assessed and cannot be recovered when cancelling a transaction. Once the cancel process completed, you will see a 0 ETH transaction on the transaction history.
