Keep it secure and don't share it. 5. **Understand gas costs** - Be aware that blockchain transactions require gas fees. Make sure you have enough ETH to cover these fees. 6. **Verify contract interactions** - When interacting with smart contracts, verify the contract address and function parameters before confirming transactions. 7. **Use onramp responsibly** - When onramping funds, be aware of any fees or limits that may apply.
