What is this transaction?

https://mempool.space/tx/a364b705609933614debc89deddad1e066188f1626067d676190b6efe438d5d1 I am seeing some transactions I do not understand. This one is stuck in the mempool even though the fee is high. It is not being added to blocks for some reason. The I puts are multisig 1/3, with the text UNKNOWN. It also shows CPFP. What is this transaction? Do other transactions need to be mined, before this one can be mined? submitted by /u/unsettledroell [link] [comments]
