The wallet address is generated by the public key. The public key is derived from the private key through an elliptic curve encryption algorithm. Specifically, the wallet address are a combination of 64 random hex characters. When you are making a transfer, you need to show your address to the other party.
The public key can be deduced by the private key and also used to generate the wallet address (Private Key -> Public Key -> Wallet Address) but cannot be reverse-engineered.
Different public chains have different corresponding asset addresses. The wallet addresses of EVM-compatible chains all start with “0”.
After the O3 cross-chain wallet is successfully created, you can view your wallet address which is a string of numbers and letters starting with “0” embedded in the official background color of the respective EVM-compatible chain at the top of the asset homepage. Alternatively, you can click the [Receive] button to view the wallet address in the form of a QR code.
