Create an Offer on Magma

1. Navigate to amboss.space/magma and click “sell channels” to open an offer form.
2. Complete the form with the following details:

   1. Total Size (sats) ≥ 1,000,000 (Don’t worry if you don’t have that many sats! Only 100k sats are needed for this exercise).

   2. Min Size (sats) = 100,000

   3. Max Size (sats) = You decide!

   4. Variable Fee (ppm) = ______________________________________________

      • This is a fee based on the size of the channel, but this is also the “cost of liquidity”. To see the current market price for liquidity, go to the LOOP page on Amboss and find the Incoming Fee Distribution chart. Set a variable fee to match the tallest bar in LOOP’s incoming fee distribution. This is a good market price for liquidity.

   5. Fixed Fee (sats) = _________________________________________________

      • This is a fee that can help you recover the cost of opening and closing a channel (two on-chain transactions). To calculate a simple cost for this, let’s assume simple transactions with 1 input and 2 outputs: 141 bytes of data. Check the current mempool fees to find the sats/vbyte.

      • $141$ bytes $×$ 2 txns $× $ ______________ $\frac{sats}{vbyte}$ $=$ ______________

   6. Channel Duration = 1 week

   7. Max Fee Rate (ppm) = You decide!

   8. Max Base Fee (sats) = You decide!

3. Send your node pubkey or amboss link to @jestopher on Telegram or info@amboss.tech.
