No you can not make transaction, Untill it get confirmed.
Bitcoin transactions are same like bank transfer, In bank transfer if you made a transaction let say your a bank acc. to b bank acc. If it is in pending you wont see the money in b bank acc. But your amount will be deducted from a bank acc. If you want to transact b bank acc. you wont see that money which is pending. Same goes wit crypto transaction.
Topic: Can I use unconfirmed funds? (Read 583 times)
You're fund of creating threads with yes-no question. I guess there's no sense to make this thread open, you may now close this thread since you already get your answers, replies are repetitive already since page 1.
Yes you definitely can use that according to Blockchain wallet but I wouldn't take that risk, better wait for 1 confirmation then cry later sir
I'm not sure about that, and I think you've already got the answer to that question. But I think this will be quite possible in the future, since the speed and number of transactions will be completely different.
So the miner can't mine the child's transaction unless the first one is confirmed?
Absolutely correct, but the other way round is when you're ready to pay additional fee for your transaction to be accelerated. Sometimes I do this when am in haste to make some transaction. Hope you're not a merchant? Kindly don't accept unconfirmed transaction because they can be there for eternity. Its when the parent transaction has been confirmed before the child transaction will be.
I think you can already used your funds or bitcoin, even your bitcoin transaction is uncomfirmed. As long it already passed step 1 because when I deposit my funds in a gambling site using my blockchain wallet, and my transaction is still unconfirmed or pending. I still have been able to spend my bitcoins or able to play slot games.
it may be too difficult to move the funds again because the previous transaction has been recorded and you better try to wait for it first,so that no funds are reduced when you insist on canceling.
I have the same problem with my money. After depositing the ethereum network, my transaction is waiting to be confirmed. In the meantime, I sent another transaction with a higher but unconfirmed gas limit. This means that both transactions are pending. I don't know what other blockchain networks will look like? Right now Ethereum is in severe congestion.
You're right, the Ethereum network is really congested that it takes days to wait before it confirmed. The situation is also being hyped as a lot of people using it due to Defi projects. It might be worsened if the surge continues and fees relatively high as well.And in your case now, all you have to do is to wait. Even you are sending again with high fees still, it takes hours/days and I don't think it is necessary since the result is still the same and pending.
@OP, it is better to wait for the tx to confirmed...though making another transaction is allowed but still nothing to happen if the first tx not done yet.
If I buy crypto for $ 5 but the contract is pending confirmation and their value could go up or down. So who will be responsible for the slippage in the meantime? I am wondering about this?
Any transaction you make with unconfirmed inputs will (ever) get confirmed only after the input(s) get confirmed, [...]
Actually it doesn't have to be only after the first transaction got confirmed, but can be at the same time (i.e. same block) too.
That's how CPFP works, the second transaction pays a fee high enough for both transactions to be included in a timely manner in the same block.
You can and this is what Child-Pays-For-Parent method is. You have to pay enough fee to get your previous transaction to get confirmed. But if the previous tx is sent by someone else, you may face problem if they intend to double spend. For example, sending tx with low fee to you and later using the same input with higher fee to another of their address.
Therefore, if the original sender is you-> no problem; if someone else-> wait for confirmation.
Therefore, if the original sender is you-> no problem; if someone else-> wait for confirmation.
That's a double spend using RBF (Replace-by-Fee), not CPFP.

I always assumed that Electrum required at least one confirmation before you can spend your coins, but I'm a pleb.
You have to turn the option to spend unconfirmed tx. I have the same problem with my money. After depositing the ethereum network, my transaction is waiting to be confirmed. In the meantime, I sent another transaction with a higher but unconfirmed gas limit. This means that both transactions are pending. I don't know what other blockchain networks will look like?

this is the answer that is most simple and easy to understand
so we can only make delivery transactions when the final or incoming balance has been confirmed or speed up the confirmation by using a larger fee to prioritize the incoming balance confirmation
Am I right?

Yes. Any transaction you make with unconfirmed inputs will (ever) get confirmed only after the input(s) get confirmed, so when "the network" "knows" you actually own those coins (with the note that this may happen even in the same block).
I sent some funds from address A to address B .
The transaction is unconfirmed. Can I send from address B to address C some funds?

This might depend on the kinda Bitcoin wallet you are using. Most of the bitcoin wallets require that at least there should be one confirmation in order to use the sent funds.
But with the third party Bitcoin wallets, once the transaction is broadcast on the blockchain network, you can use the funds when there is zero confirmation.
So the miner can't mine the child's transaction unless the first one is confirmed?
That's correct. (You can't spend money you don't actually have, right?)
However, you can use CPFP and pay a bigger fee for the child tx to increase the priority of the parent tx.

If you are talking of sending some or whole part of the money you intend receiving from B then It it impossible. The transaction need to be confirmed and show in your wallet before sending back.
No.
You obviously didn't read the thread and are just here to spam for your sig campaign.
As mentioned by multiple people already, you can indeed create transactions with outputs which aren't confirmed yet.
That's how CPFP basically works: Creating a transaction with unconfirmed inputs using a fee high enough to pay for both transactions.
Sometime unconfirmed transaction might be stall when the gas fee is not enough so it is very important for a transaction to be confirmed before you send money
Gas fee?
You do realize that everyone is talking about bitcoin here, and not about any

Which wallet allows sending without a confirmation?
Lots of them. I do this in Electrum frequently.
It is entirely possible to spend unconfirmed transactions. Spending unconfirmed funds is exactly what a child-pays-for-parent (CPFP) transaction is. Either the first transaction will be confirmed first and the second transaction confirmed in a later block, or both transactions will be confirmed at the same time in the same block.
If you are not in a hurry, you can chain up any number of unconfirmed transactions with any fees you like and simply wait for them all to confirm. If you are in a hurry, then you can effectively "bump" the fee of the initial unconfirmed transaction by paying an excessive fee on a second transaction. If the average fee rate of the two transactions together is high enough, then miners will include the initial low fee transaction so they can also include the second high fee transaction in the same block.
There are uncommon but potential issues with chains of unconfirmed transactions, such as transaction malleability, but that's outside the scope of what OP was asking.
What? UNCONFIRMED? Am I the only person who doesn't know this because I never tried it? Haha.
I always assumed that Electrum required at least one confirmation before you can spend your coins, but I'm a pleb.
I have not use electrum yet, I just use a local wallet, and yes as what the others said you can do it in electrum.
I never tried to spend any of my unconfirmed funds in my wallets but its possible on exchanges and gambling sites I guess, because once I send bitcoin to my exchange wallet which has less confirmations only but still it is showing on the exchange's wallet balance and I can be able to trade with it.
IIRC the limit is 32 transaction depth, so you don't need to worry about the limit unless you make 32 chaining transaction (e.g. address 1 -> address 2 -> .... -> address 33) 
It's actually 25 (https://github.com/bitcoin/bitcoin/blob/cb1ee1551cf39905ccb67e3d07b0e3aaaca18ce3/test/functional/mempool_package_onemore.py#L15). If you try to chain any more, you get the error "too-long-mempool-chain, too many unconfirmed ancestors [limit: 25]" (https://github.com/bitcoin/bitcoin/blob/cb1ee1551cf39905ccb67e3d07b0e3aaaca18ce3/test/functional/mempool_package_onemore.py#L69)I always assumed that Electrum required at least one confirmation before you can spend your coins
Nope. There is an check box under Tools -> Preferences -> Transactions titled "Spend only confirmed coins", but it should be disabled by default.There is risk involved, as if the initial transaction is replaced with RBF or double spent, or is changed via malleability, for example, then any subsequent transaction will become invalid and therefore be rejected from the mempool.
