Something I just noticed: The fee estimate was slightly higher than the actual fee paid, 896 vs. 888 sats. 
Update:
Sent ~50K sats on-chain to nostr:npub1mutnyacc9uc4t5mmxvpprwsauj5p2qxq95v4a9j0jxl8wnkfvuyque23vg at 6 sat/vB for 884 sats.
Swapped max to Lightning for 888 sats.
Total cost to fund my first channel: 1773 sats.
