Is 500.14kB really that large? And I thought it's just about the fee rate which is 29.4sat/vB. But looking at the mempool, I see that 29.4sat/vB is not unheard of.

So I guess it makes sense that someone would pay this rate which then results in 3M sats for a transaction this size.

Edit:

Okay, yeah, 500kB _is_ large. It's [half a block](https://mempool.space/block/000000000000000000070742427fa10ec3c66d006160155a704d9f56d090a3ea), lol. (Quarter when accounting for SegWit)

This is the tx that broke lnd today. It was pretty large and they likely contacted the miner out-of-band to get it in, and at that point likely locked in a high fee rate.
