Sr25519 ＆ Sd25519 （For Polkadot network only）

Using different Key Pair crypto types will create different addresses under the Polkadot network by using the same seed phrase. Under the Polkadot network, we use Sr25519 as a default. If your tokens disappeared under Polkadot network, try to import the wallet again by using the same seed phrase but choosing the other key pair crypto type.
