Sovereign Settlement Made Simple
New to Bitcoin?
Paying with Bitcoin takes about two minutes. Here's the whole thing, step by step — no jargon.
- 01
Get a Bitcoin wallet
Download a free wallet app — Cash App, Strike, BlueWallet, Exodus, or any wallet you like. Buy a small amount of Bitcoin (BTC) inside the app, or transfer in what you already hold. That is all you need — no special account with us.
- 02
Check out & get your invoice
At checkout we show you an exact Bitcoin amount, a receiving address, and a scannable QR code. The amount is locked to the live USD→BTC rate at that moment, so you always know precisely what to send.
- 03
Scan and send
Open your wallet, tap “Send,” and scan the QR code (or copy-paste the address and the exact amount). Confirm in your wallet — that broadcasts the payment to the Bitcoin network. Sending the exact amount shown matters.
- 04
Confirm & ship
Email a screenshot of your wallet/blockchain confirmation to spartapeps@gmail.com. Once your payment is verified on-chain, your research materials ship within 24 hours.
⚡ Want it faster & cheaper?
When available at checkout, Lightning payments settle in seconds with very low fees — just scan the same way from a Lightning-enabled wallet. Standard on-chain Bitcoin works perfectly too.
Heads up: all payments are made in Bitcoin and are final and non-reversible — there are no chargebacks. Please review your order carefully before paying.
