Separate a legitimate service condition from a request for secret access.
LET’S PICTURE IT
A rehearsal venue may ask who is attending, but it does not need the keys to your home.

From a public address to a verified signatureStep 1 / 4
An address is public receiving information. It is not the private key that authorizes actions.
An address is public receiving information. It is not the private key that authorizes actions.The local signing system uses secret authorization material. It produces a signature; the private key is not sent along with it.A verifier checks the signed request under the account’s rules. A valid signature does not by itself prove that the action is safe.Balances belong to network state. A wallet is an interface and signing system, not a box containing coins.

Know the stated task
A faucet distributes test assets on a specific network under its own rules. It may have rate limits or identity requirements. Read which network and asset it claims to provide and verify the service through trusted references.
A receiving address is public input
A service can send to a public address without knowing its private key or recovery phrase. A field asking for those secrets is not required merely to receive a test transfer.
Examine additional requests
Some services may ask for sign-in or other actions. Evaluate the exact data and permissions requested, and do not assume “testnet” makes every signature, download or payment safe.
Avoid urgency around free practice assets
A shortage of test assets is not a reason to enter a mainnet phrase into an unfamiliar page. EtherTools’ initial experiments avoid faucets altogether, so you can continue learning while investigating a service carefully.
QUICK CHECK · NO PRESSURE
What is sufficient as a basic destination for receiving a test transfer?
Receiving does not require disclosure of secret authorization material.
