Test Wallet Generator — FAQ
Are generated wallets real?
No. Generated wallets are structurally valid but should never be used for real funds. They are intended for development, testing, and educational purposes only.
Where is my data processed?
All generation happens entirely in your browser. No data is sent to any server. Generated private keys and mnemonics never leave your device.
How are wallet addresses generated?
We use the Web Crypto API for cryptographically secure random number generation, combined with elliptic curve cryptography (secp256k1) for public key derivation.
