Separated Witness – Why can’t I find my transaction in Mempool?

adminApril 18, 2024

We build a basic segwit raw v2 transaction using the pwpkh address and get the decoded transaction as follows:

I sent a transaction and it returned txid “faf1b468b3f25a8c48deff47be8ab969a638a9e4f3fd618b2d2f37d3f141b90b”. I can’t find it in Mempool or Blockstream’s testnet block explorer, and I’ve checked the transaction format over and over again and haven’t found any problems. Can anyone help me check this?
