We were actually using the last commit tx's size, since we were setting it in lightningd. Instead, hand the min and desired feerates to closingd, and (as it knows the weight of the closing tx), and have it start negotiation from there. This can be significantly less when anchor outputs are enabled: for example in test_closing.py, the commit tx weight is 1124 Sipa, the close is 672 Sipa! Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Changelog-Changed: Protocol: Use a more accurate fee for mutual close negotiation.
