SECURITY AT ASTER

Paranoid on your behalf, invisible in your way.

Every card, deposit and login runs through systems built to assume the worst — so you never have to think about it.

E

Encrypted end to end

Card numbers are shown to you once over an encrypted channel and stored only in hashed form. TLS 1.3 everywhere, AES-256 at rest.

3D

3-D Secure on every card

Checkout challenges route to your device for biometric approval. Card-not-present attempts you didn't start get blocked, not questioned later.

F

Fraud watch, around the clock

Velocity spikes, odd geographies and retry storms are flagged in seconds and reviewed by humans — median case time 22 minutes.

K

Passkeys & 2FA

Sign in with a passkey, approve transfers with your face or fingerprint, and get plain-language alerts when anything changes.

Found a vulnerability?

We run a responsible-disclosure program and pay for verified reports. Email security@aster.money with steps to reproduce — first response within 24 hours, and we'll never take legal action against good-faith research.
