For customers
Cryptocurrency (current)
We accept three rails through NOWPayments, a regulated crypto payment processor. After clicking Place order, you'll be redirected to a NOWPayments-hosted payment page with a QR code, the exact send amount, and a deposit address that locks for 20 minutes.
- Bitcoin (BTC) — 1 confirmation required (~10 minutes average).
- Ethereum (ETH) — on-chain. ~2 minutes for confirmation.
- USDC (USD Coin) — stablecoin on Ethereum. Recommended for predictable pricing.
Quoted price is locked for the full 20-minute window. If the network is congested and confirmation lags past that, the NOWPayments invoice will refresh automatically with a re-quoted rate before you send.
Card and ACH (coming soon)
Credit/debit card (Visa, Mastercard, Amex, Discover) and US ACH bank transfer are on the v2 roadmap and will be enabled by an admin flag when ready. We are not collecting card or ACH details yet.
What we don't accept
- PayPal (their terms prohibit our category)
- Personal checks or money orders
- Cash on delivery
- Buy-now-pay-later services (Affirm, Klarna, etc.)
- Gift cards from third parties (only Peptide.best gift cards work)
Currency & pricing
All product prices are USD. NOWPayments converts to your chosen cryptocurrency at checkout at the spot rate plus a small processor fee.
Security
The NOWPayments invoice is hosted on their domain and we never see your wallet's private key or any sensitive funding source. Read more in our privacy policy.
Refunds
Refunds are paid back in the same cryptocurrency to the wallet you sent from, valued at the USD value of the original charge (not the current crypto price).
For vendors — how you get paid
Vendors are paid in USDC on Ethereum. Set your ERC-20 wallet address in the vendor portal → settings page. The moment you mark a line item shipped, the platform treasury wallet signs and broadcasts a USDC transfer to your address for the line subtotal minus the 15% commission. Typical end-to-end time: 2–5 minutes. Every transfer has a tx hash you can verify on Etherscan; you can see the full history under Payout History.
