# What is My Wallet Address?

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.

{% hint style="info" %}
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.
{% endhint %}

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.
