Stuck transaction

[hosseinimr93]

Don't worry these low-fee 1sat/byte transactions get confirmed eventually you'll just have to wait.

Transactions are usually confirmed even if the fee rate is too low, but there is no guarantee that your transaction will be finally confirmed.
Your transaction will be removed from the mempool, if it isn't confirmed in 14 days. It's also possible that your transaction is removed from the mempool due to limited capacity of the mempool.

You can use some free tx accelerator to speed things up.

The only working free transaction accelerator I know is ViaBTC which doesn't accept transactions with the fee rate of lower than 10 sat/byte.

Thanks again everyone! Mempool traffic is kinda bonkers lately huh!? Is this mostly from inscriptions/ ordinals?

Correct, the trend continues towards the upside after Luxor, a bitcoin mining pool, mined a record-setting 3.96 MB block (#774,628) on the Bitcoin blockchain[1]. We are witnessing a sharp around 122% increase in btc network fee one week after this[2]. Its mainly caused by ordinals + we got some cpi data yesterday which increased the volatility and maybe transactions increased a bit more causing more congestion.

Hasn't your transaction been removed from the mempool?
Due to big size of unconfirmed transactions and according to mempool.space, transactions with the fee rate of less than 1.41 sat/vbyte are purged from the mempool.
Can you still see your transaction on block explorers?

[khaled0111]

it was a p2p trade on a decentralized bitcoin exchange.
I set the fee for 1 sat /vb when receiving the transaction.

Not sure about this p2p exchanges policy when it comes to canceled transactions, but if I were you and the transaction is still stuck then I would accelerate it immediately by sending the unconfirmed output to one of my addresses (CPFP) to avoid any trouble.
Mempool is so congested right now (>360mb of unconfirmed transactions) and it may take days before it clears up. Your transaction may get purged in the meanwhile!

Not only the wallet support RBF, the transaction itself must have RBF flag enabled.

As I explained above, now that a significant minority of the network is running full RBF, and at least one mining pool is mining full RBF replacements, then this isn't strictly true anymore.

Note that there is actually "only" around 65 vMB of unconfirmed transaction in the mempool. The 360 MB figure you are quoting is the dynamic memory usage (i.e. the RAM usage) of these transactions after they have been deserialized. If no more transactions were added to the mempool, and assuming an average block size of ~2 vMB, then it would take 33 blocks to clear this backlog, and not 180 blocks.

Mempool has 80vMb with higher purging rates than others, make that ~120vMB at 500MB with purging everything under ~1.2sat/b, so one can easily assume that if a bit of it is cleared a lot of the 1sat/b sanctions that have been purged will come back, it's highly unlikely that everyone that had a broadcasted 1sa/b tx just went and upped the fee. Then add the extra 37 blocks we had due to more hashing power and it's a lot worse than just 33 blocks.

3 days till the weekend, although the mess started also during the weekend!
Does anyone have a link, graph or something that counts these "minting' transactions/day?

Sorry   for not mentioning that my 1sat/vb transaction did clear a few days ago . A 3sat/vb cleared pretty quickly a few days ago also. I've heard of 10sat/vb taking over 6 hrs as of yesterday.  

Me personally I wont be setting a 1sat/vb transaction anytime soon. Maybe ever. Those extra sats/vb I pay extra hopefully will save me time and headaches.  

I find those accelerators pretty fishy.

Thanks everyone! I appreciate all of you!

I find those accelerators pretty fishy.

Viabtc worked for years, but only if you pay at least 10 sat/byte. And by the time that's needed, you won't be the only one so it's hard to get into their queue. All the other "free accelerators" are useless.

If you set the fee rate to 8 sat/vbyte, your transaction would be less than 1 vMB from the tip and will be probably confirmed soon.
Note that the required fee is dynamic and it can change over time. If I were in a hurry, I would set the fee rate to 10-12 sat/vbyte.

I also confirm that ViaBTC free accelerator works well.

You can set 1 sat in whatever you want, But 1st, before you set it, just look on mempool 1st and look at how many transactions are at that time. Because, sometimes I ever look at 1 sat that only has under 500 txs unconfirmed, which means with 1 sat you only have to wait about 10 minutes to confirm.

Just save your sat.
why should be more if you can 1

[hosseinimr93]

You can set 1 sat in whatever you want, But 1st, before you set it, just look on mempool 1st and look at how many transactions are at that time.

For estimating the required fee rate, you shouldn't look at the number of unconfirmed transactions. You should look at the size of unconfirmed transactions, considering that each block can include up to 1 vMB of transactions.

Not only the wallet support RBF, the transaction itself must have RBF flag enabled.

As I explained above, now that a significant minority of the network is running full RBF, and at least one mining pool is mining full RBF replacements, then this isn't strictly true anymore.

In other words, it's still generally true. Besides, the wallet software must have feature to create conflicting transaction or at least delete unconfirmed transaction from the wallet itself.

Does anyone have a link, graph or something that counts these "minting' transactions/day?

User @d5000 create one, although it's about size/day rather than TX/day.

I made a little visualization about the size of ordinal inscription transactions, to be able to follow the evolution of their impact in the chain:

Don't worry these low-fee 1sat/byte transactions get confirmed eventually you'll just have to wait.

This isn't accurate. Most node have 300MB mempool size limit (after transaction is deserialized) and currently unconfirmed transaction already surpass the default limit. If you bother visit https://mempool.space/, currently it purge all transaction with fee rate < 1.08 sat/vB from the mempool.

Well, my only source is my experience. And so far every single tx with 1sat/byte fee has been processed eventually just like I mentioned before. Disclaimer: I don't send/receive Bitcoin every single day so perhaps there are periods of time when it won't work. But I've been lucky so far.
