Now I get it... it's maybe other users who transfered their tumbled coins with a CPFP transaction with significantly higher fees and which bumped the effective fee rate of the tumbler's payout transaction from initially way too low 15sat/vB to ~44sat/vB. The tumbler pays the finally mixed coins to various users which used the tumbler.
It's his own transaction from 'Wallet A' to 'Wallet B';
Wallet A used the UTXO from the received txn from the tumbler to send that transaction, effectively bumping their effective fee rate.
I can choose to accelerate it thru mempool.space but will that even work?
What do you think should i give it 1 more day or will this not show up to wallet "A" since it hasnt been confirmed over 2 days?
Dont really care about the fee to pay IF the accelerate option is working, i just need to get this transaction done in one way or another. cost of fee will not be an issue.
mempool.space's accelerator needs an account and it need to be activated by them,
mine which was registered about a month ago is still in their "
waiting list".
They don't usually drop transactions in that online wallet, even after the 14days default nor even after it reached the bottom of a default mempool size.
Don't expect it to be dropped without any intervention from the sender, they'll have to spend its input to effectively "
cancel" it.
You can just create a CPFP to the transaction that's sent to wallet B.
The issue is if Wallet B supports it or if you can at least export its seed phrase (
12/24 words) to be able to import to a wallet that can do it.
Example, if you can a manage to import it to Electrum: all you have to do is to right-click on the unconfirmed transaction and select "
Child pays for parent" to create a children transaction with very high fee rate, then 'sign' and 'broadcast' it.
