// crypto-only billing

Pay in crypto.
No card on file.
No KYC.

TartarusAI is billed entirely in crypto — USDT (TRC20 / ERC20), Bitcoin, and Ethereum. Prepay 1, 3, or 12 months; annual saves ~20%. New periods stack on top of any remaining time on your plan. No recurring charge, no chargeback risk, no card sitting in our database for someone to leak.

// why crypto

Three reasons.
All structural.

No deplatforming risk

Stripe/PayPal can suspend a category overnight if the category looks adversarial. Crypto rails do not have that exposure. Your subscription does not depend on a payment processor agreeing with the category.

No chargeback class

Crypto settlement is final. We do not need fraud-detection middleware, friction-heavy KYC, or invasive 3-D Secure flows because the chargeback vector does not exist. Cleaner UX for everyone who is not committing fraud.

No card-on-file attack surface

We do not store your card because we never see it. The most boring privacy improvement is the one where the data does not exist in the first place. Particularly relevant for an audience that values operational separation.

Common questions.

Which crypto currencies do you accept?+
USDT TRC20 (recommended for low fees), USDT ERC20, Bitcoin, Ethereum. The dashboard generates a fresh address per invoice and confirms automatically once the network settles.
Is there KYC for any tier?+
No KYC for Lite, Pro, or Pro+. Enterprise tier has a light verification step because the contract is bilateral (NDA, SLA, on-prem option). Sub-Enterprise tiers operate purely on email + crypto address.
Can my company expense this?+
Yes. Receipt PDF includes invoice reference, USD amount, crypto amount + currency + transaction hash. Most accounting departments accept this for reimbursement; a few do not — check before subscribing.
