What Ryntra does and does not do
- Ryntra holds no keys and no funds: every payment is signed in the payer's own wallet.
- Checks cover payments prepared in Ryntra. A wallet can still sign anything outside it.
- Arc Mainnet in early access: every payment has a ceiling, and payments can be paused at any time.
- Ryntra does not check who asks to be paid. Pay only people you know.
- A payment request is kept for this browser; there is no team sign-in yet.
- Not audited. Not financial advice.
