If you remove the ETH wallet from imToken and re-import the mnemonic or import the mnemonic into another device, the staked ETH will not show up in imToken. The staked ETH is stored on the Beacon Chain, a chain separate from Eth1, so you need to generate the Eth2 public key in the management page first, then you can see your staked ETH.
Please follow the steps below to restore the display.
- Click "..." at the top right corner of the asset page
- Click "Eth2 Management" in the manage page
- Click "Create".
After the Eth2 public key is successfully created, you can see the staked ETH again when you return to the Eth2 staking page.
