I despatched the transaction and return a txid,”faf1b468b3f25a8c48deff47be8ab969a638a9e4f3fd618b2d2f37d3f141b90b”.
My query is: I cannot discover it within the mempool or blockstream(testnet), and I checked my transaction format time and again, however discover no issues, so anybody might help me test this?
