It doesn’t, won’t or can’t? Seems like that would be a good mint business model
Don't use eNuts it isn't maintained. Use cashu.me or nostr:nprofile1qqstxwlea9ah3u6kjjszu6a7lrnhqkfh8eptp2z6v0e9558tlkkl2rgpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsz9mhwden5te0wfjkccte9ec8y6tdv9kzumn9wshszxnhwden5te0wfjkccte9ekkjmnfvf5hguewvdshx6p07xr4s5 . Sounds like you are trying to open a channel with the token. Cashu doesn't take fees to redeem. There are fees to send a lightning transaction however.

cashu mints CAN't take fees to redeem ("swap") tokens, they SHOULD however take fees to melt or mint tokens (i.e. move in and out of the mint).
