Terms of service.

Hvisk operates a privacy layer for stablecoin payments on Solana. We provide software you can run on a phone, a relayer service that broadcasts your signed payment intents to the network, and an optional SMS gateway. We do not custody your funds.

Your private key is generated and stored on your device. Hvisk cannot recover it on your behalf, freeze your funds, or reverse a transaction once it has settled. Loss of your device or recovery phrase may result in permanent loss of access to your wallet.

You agree not to use Hvisk to facilitate money laundering, terrorist financing, sanctions evasion, fraud, or any activity unlawful in your jurisdiction. We reserve the right to refuse service to addresses associated with such activity.

On-chain settlement fees are paid in SOL. Hvisk may charge a small spread on relayer service or on the privacy pool; these are published in the documentation and shown before each transaction.

Hvisk is provided as is. Privacy guarantees are cryptographic and depend on the correctness of underlying primitives (Groth16 SNARKs, Ed25519 signatures, Solana consensus). No system is perfect. Use sums you can afford to lose while we mature.

We may revise these terms. Material changes will be announced on this page with the date updated above.
