Hi, I did a BTC Swapout with a Peer:
Our channel has more than 5M of outbound liquidity.

Then the code sent this to him.
`⚡️ Sent 17,848 to Tiger 🐯 out Tiger 🐯 - Friendspool⚡🍻 023e2460`

First question: what is this amount? Is it a service fee? If it is, how do I set it?

The peer received:
`💵 Received 17.848 for “peerswap btc fee 811731x986x0 7ba0b4122bb3a9f5e35ac714d89104501fecfa588f354fd2cf4e1515df6ac75a” via Friendspool⚡🍻`

And then sent:
`⛓ (pending) Sent 2.007.985. Paid 7.985 fee. Sent to bc1qaneettmxu5ydrrcf0x6jy33efckdyfay08jxvj, bc1qr2saufdfz92pq62pxf3xtqdhqtqzudnlmg9a7mhsdyqzste6fyhsj68plf`

Then I received:
`⛓ Received 1,991,494`

And Paid:
`⚡️ Sent 2,000,000 to Tiger 🐯 out Tiger 🐯 - Friendspool⚡🍻 023e2460`

Second question: If my peer sent 2,007,985 and I received 1,991,494, on-chain fees were charged twice? Why?

Please help me to understand what happened.

Thanks
