Support

In plain words: if you want to send sats to keep an archival Bitcoin node and free research running, here is a fresh address. Any amount. Nothing is stored about you. You can bookmark the page and return to the same address.

Everything on this site stays free whether or not anyone donates.

Not a sale

Donations are not sales. Our kill-gate counts stranger purchases only — a tip is generous, but it will not be counted as evidence that this shop works.

JavaScript is off

Open the endpoint directly: /api/btc/donate — it returns JSON with an address and bitcoin: URI. Append ?ref= plus a 32-hex string to re-derive the same address forever.

What this is not

Not a product purchase and not a receipt
Not a running total, goal bar, or public ledger of tips
Not email, thank-you flow, or name collection
Not next to a buy button — optional support only
