Free, private, and yours.
No ads. No trackers. Keys in your hands — with a real exit path.
-
No ads or trackers
We don’t sell ads and we don’t track you. Your chats and payments are yours.
-
Open source
Every line is open to inspect and audit. No black boxes, no “just trust us.”

Self-custodial on Ark
Your keys, your coins. The L2 operator can’t steal — you can always exit on-chain.
-
Not trustodial Spark
Radar-smooth UX without parking funds with a custodian. Unilateral exit is the point.
-
Signal encryption
Battle-tested end-to-end messaging. Payments ride as ordinary encrypted messages.
-
