Topic: Which wallet is working the best in face of malleability ? - page 2. (Read 1783 times)

Just use the Core and don't hurry, so you can afford several confirmations before spending, and you will be safe

i've heard that 1 confirmation, isn't enough to be sure that your transaction was spent, with this fancy attack?

i must wait for six confirmation for the time being? or i can... dunno, goes well with 3?

The best wallet selector website I've found yet, check it out -> https://bitcoin.org/en/choose-your-wallet

These are not all the wallets available, but it's a good start.  Good luck!

I'm the user of Multibit and Electrum. Any user experience with these wallets must be most appreciated. Right now I do not have any need to spend my bitcoin but for the precautious step I need to know how to handle the attack and do not get panic.

I think miltibit should handle it good because it don't let you spend btc who isn't confirmed. That way you will not have problem with double spend like those who blockchain give you when you spend unconfirmed btc and one of the inputs get mutated by the malleability bug.

I only use Mycellium.

First of all, UTXO generally stands for Unspent tx(transaction) Outputs, and you must spend an unspent transaction output in order to create a valid transaction.

Based on the title of this thread, I will assume that you are looking for a wallet that will not attempt to spend an unconfirmed output from a transaction that has not yet confirmed, and will answer accordingly.

First of all, you should be sure not to reuse addresses, and doing this will make it much easier to avoid spending an unconfirmed output.

Once you are following the above rule, you will want to find a wallet that allows for coin control. I would personally recommend using electrum as it is a lightweight client (meaning it takes up very little resources), that will generally be able to validate when you have received a transaction, and is deterministic (so all you need to recover your private key is your recovery seed). You can use the coin control features with electrum (both "freeze" addresses, and "send from") to spend only inputs that are confirmed. You can "freeze" addresses when you do not wish to spend BTC "in" those addresses, and you can "send from" addresses whose inputs have sufficient confirmations (you can even select multiple addresses to "send from").

If you are already running a full node locally (or if you are giving immediate credit to people who send you BTC) then you may want to use armory. Using armory will require you to run a full node locally, so any transactions will be fully validated which requires an incremental lesser amount of trust then using a light weight wallet. Armory has similar coin control features that electrum has, although I believe they are titled something different.

I have used coinbase many times and until now yes.
Here is an article about "Does Coinbase pay bitcoin miner fees?"
https://support.coinbase.com/customer/en/portal/articles/815435-does-coinbase-pay-bitcoin-miner-fees-

Coinbase does not need to pay anything fro their internal settlement. But, Coinbase is paying Tx fee even when the Tx is going out of Coinbase too?

Since coinbase pays the fee for their users i am using it.
The fee that they applies at the time of melleability attack is somewhere at 0.0002-0.0004
But dont consider coinbase as a wallet because they don't give you private key. GL

It seems blockchain.info has shortened their pruning time. Hence, Tx affected by malleability are getting cleared from their nodes sooner and hence users are being able to reuse those UTXO faster.

Bitcoin Core seems the most logical choice, I think. Armory allows you to handle this too, probably Electrum, but don't quote me on that. breadwallet also handles the situation quite well, but I'm not sure if it allows you to spend unconfirmed.

I don't know which one works the best, but I do know which one works the worst definitely.

Stay away from blockchain.info wallet !!!

I think, the one which does not spend UTXO or at least offers a choice not to spend the UTXO, will serve the best...
