Testnet gas is shared infrastructure. Without practical safeguards, automated requests can drain a wallet before developers and learners get a chance to use it. ZalalenA PoW Faucet uses a modest browser puzzle as one signal that a request is coming from an engaged user.

The browser creates candidate work while the server independently verifies every accepted share. Reward accounting, cooldown decisions, and transaction delivery remain on the server. The system does not mine a cryptocurrency and does not create real value.

After a session reaches the configured amount for its network, the same public wallet can claim its testnet reward. The resulting transaction can be checked through that network's explorer.
