Eth2 public key address is the identifier on the Ethereum 2.0 network. Ethereum 2.0 uses a completely different elliptic curve to create the private key and generate a public key address, which is different from Ethereum 1.0. So we need an Eth2 wallet to manage the keys.
Within imToken App, one mnemonic phrase can manage both Eth1 and Eth2 wallet addresses. A wallet’s address can be generated (i.e. seeded) and imported from the mnemonic (i.e. seed phrase)
Generate an Eth2 withdrawal key via path m/12381/3600/0/0 according to the EIP-2334 specification.
