# To send or receive crypto

To send or receive crypto, all you need to do is **copy and paste your wallet address**—it's that simple! Your wallet address is a unique identifier that allows you to send, receive, and store assets across different blockchain networks like **OptimusZ7**, **BNB**, and **Ethereum**. By sharing this address, others can send you crypto without needing any personal information.

When making a transaction:

1. **Sending crypto**: Paste the recipient's wallet address into the appropriate field when making a transfer.
2. **Receiving crypto**: Share your wallet address with the sender, and they can transfer funds directly to your account.

Always double-check the wallet address before sending or receiving funds, as transactions on blockchain networks are irreversible. With OptimusZ7’s high security, you can be confident in the safety of your transactions.
