Follow these checks in order
Verify the source
Use a source you have checked yourself, review the app identity and permissions, and avoid installer links sent in unsolicited messages.
Create or import
A new wallet generates new recovery credentials. Importing uses existing credentials. Choose the path that matches your situation.
Back up before funding
Record the recovery phrase offline and verify every word and its order before transferring funds.
Test carefully
Check the receiving address and network with a small transfer before moving a larger amount.
Next step
After each step, verify the public address and network before moving assets.
