RainbowID: Multi-Chain Wallets Management

Rainbow Wallet v3.2.0 provides RainbowID feature. With this new feature, users can utilize one set of Mnemonic to efficiently manage multi-chain wallets.

Through creating RainbowID, there will be addresses and corresponding default wallets automatically generated on each supported chain. Meanwhile, users can choose to further create several custom HD wallets based on RainbowID, so that they are able to use different wallet addresses according to their own needs to better protect the transaction privacy and impove the asset security. All these multi-chain wallets can be efficiently managed with one same set of Mnemonic.

Mnemonic: Flexibly Import and Check

Rainbow Wallet v3.2.0 improves and upgrades functions for Mnemonic. Users can import the pervious wallets into Rainbow Wallet App by entering their 12 or 24 seed phrases, having more flexibility to utilize and manage wallets. In addition, Mnemonic can be viewed now so that users are able to have a more convenient experience.
