Prices and fees
Every cost, what it pays for, and when it can change. All amounts are integer satoshis; the site never uses floating-point Bitcoin values.
The four components of a mint
| Component | Amount | What it pays for |
|---|---|---|
| Collection price | 8,888 sats public, 0 sats with a Knot Heads credit | The Feline itself |
| Bitcoin network fee | live, set by the fee rate you choose | Miners confirming the transactions |
| Inscription delivery | 546 sats per Feline, plus its share of the network fee | The output that carries the inscription to your address, and the transaction that reveals it |
| Service fee | 1,500 sats on a paid mint; 0 sats when every Feline in the order uses a credit | The house constructing, verifying, and shepherding your inscription |
The signed quote lists each component and one exact total before your wallet opens. Nothing is added afterwards.
Two details worth knowing about the parts you do not pay:
- The 546 sats is not a fee. It is the smallest amount Bitcoin will let an output carry, and it is the output that holds your Feline. It arrives at your address with the inscription and stays yours.
- The commit transaction is on the house. Inscribing takes two transactions. You are quoted the reveal; the commit is funded by the house and appears on your bill as zero.
You can order 1 to 20 Felines in a single checkout, and hold up to 3 unpaid orders at a time. Cancelled, expired and failed attempts never count against that limit.
When the service fee applies
The service fee is charged on paid mints only, and it is decided by the whole order, not per Feline:
- An order made entirely of free-mint credits (every Feline at the 0-sat collection price) carries a 0-sat service fee. There is no service-fee output in that payment at all.
- An order with any Feline at the public price pays the flat 1,500 sats once, however many credits the rest of the order uses.
- A signed quote issued before this policy keeps the fee terms frozen into its own pricing version. An old quote still verifies exactly as it was signed; nothing is repriced after the fact.
The signed quote
When you request a quote, the server calculates every component from the live fee market and signs the result. That signature means:
- the total cannot drift between the page and your wallet;
- the quote is valid for 15 minutes, then expires;
- an expired quote is never silently reused. You request a fresh one and every component is recalculated and re-signed.
Prices are server-authoritative. The page displays the quote; it never computes one.
Fee bumps (RBF)
If your payment is stuck below the going fee rate, the app can offer a replacement transaction at a higher rate:
- On a paid or mixed order, each accepted bump adds exactly 1,500 sats to the cumulative service fee, shown before you approve. An all-credit order adds nothing: its service fee is 0 sats before and after any bump.
- The Bitcoin network fee rises with the fee rate you select, disclosed separately.
- A rejected signature, duplicate click, retry, or failed broadcast adds nothing.
- Replacements preserve the mint output and may only add verified asset-free inputs from your wallet, so no inscription you own can be swept in as fee material.
What holders pay
A Knot Heads free-mint credit sets the collection price of one mint to 0 sats. Network and delivery costs remain payable, because those are real Bitcoin costs the house passes through at cost. The service fee follows the whole order: an order made only of credited Felines pays 0 sats service fee, and an order that also includes a Feline at the public price pays the flat 1,500 sats once. See Community credits.
Historical prices
Earlier pricing versions (v1 through v3) posted different rates. They are historical only: already-signed quotes under them remain verifiable, and the remediation program compensates eligible early minters. The only active contract is forked-felines.community-remediation/v4. See Remediation and refunds.
