If you can't select all the way down to 0 or 1 sat/b (as has gotten nextblock confirms when I looked at recent blocks within the last day), it's not 100% custom.
And they support this. They always had the option to allow you to manually customize the exactly amount you want to pay on fee with a textbox, and they also have a option to enable dynamic fees, where they will give you a few options based on calculations on their side - just like I said above. Tools -> Preferences -> check "Edit fees manually"; ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Ftalkimg.com%2Fimages%2F2023%2F05%2F14%2Fblob4c04622f81282913.png&t=665&c=MxfAqMcE23XZYA)

I'm the only one who can't manage to get the last update? the wallet didn't auto update and when I check for new update through the menu, It says that I'm 2.9.2 and It's up to date while there is clearly a new version out.
I think their "in app" 'check for updates' system is broken... Mine says "you're up to date"... I'm on 2.8.12... and Play Store has 2.9.3 and the "update" button ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif)

Thank you for clarifying this, pardon me earlier. But I much prefer use mycelium for faster confirmations tho, and electrum for multiple sending.

Faster confirmations? I don't understand how the wallet has anything to do with confirmation time... The confirmation time is based on fee rate and the current network conditions. If you send identical transactions from WalletA and WalletB at the same time, both with fee of X sats/byte, they should theoretically confirm at the same time. The network has no idea what wallet they've come from, so saying "WalletA gives faster confirmations than WalletB" is nonsensical.

Please read the later post why I said 'Faster confirmation' using mycelium wallet. We're talking about transaction fee amount here and all you said is right but I'm more convinced that having large fee has the large chance to confirmed first. Since mycelium fee is much higher than electrum, having such 130 sat/byte as lowest fee IIRC (before the recent update) than electrum having 90sat/byte as the lowest fee or even lower base on number as mentioned of tryninja since I never used that number of fee with electrum...

I had 2 incoming transaction yesterday but both have problems: 1st - Unable to broadcast 2nd - Unconfirmed parent On txid they are with 60+ confirmations, so looks like it is mycelium problem. Anyone had similar issues? Do I have to just wait of is there a fix to this?

At the end of the day you are the one choosing how much in fees you want to pay. It doesn't matter which wallet you are using. Both will provide you with the same confirmation time since both wallets let you send a transaction with the same fee. You can't say that X wallet is "faster" because they charge higher fees. That's just dumb.

i had this too. the transactions are valid. what mycelium is displaying to you is wrong. i sent out from the wallet while this was happening and it went through fine despite what the wallet was telling. maybe in retrospect i should've waited for it to sort itself out just in case which it did a couple of hours later.

Hi,
Where can I find out what format my Mycelium hd wallet account's keys are in, when exported to my device screen.
I had a look at 'compressed' and 'uncompressed' but I have a hexadecimal string which is 112 characters, rather than 66 or 130.
Thanks

Mycelium will either let you backup/export your master seed (ie. 12 word seed mnemonic) or a "Master Private Key"... aka "xprv".
I'm fairly certain it doesn't dump the individual keys for each address in your HD account... Does the key you see start with "xprv"? If so, it is a Master Private Key.

Yes. It is a master public/private key pair which it is displaying.
So if I want to back these up manually using the clipboard, then these are the only keys I need to back up for the HD account in question, correct?
It is currently saying '"Contains 3 private keys"
Is there any reason to locate and backup those 3 individually generated key-pairs? Are they forever hidden in the app?

If there's another Bitcoin fork then you might need those individual keys, it depends on how the wallets choose to incorporate it. In almost all cases all you'll need is the seed. If you really need individual keys then this will extract them - https://github.com/iancoleman/bip39 but it doesn't discriminate between used keys and unused ones so you may be in for a lengthy search.

If you really need individual keys then this will extract them - https://github.com/iancoleman/bip39 but it doesn't discriminate between used keys and unused ones so you may be in for a lengthy search. If I understand what's going on here, you're planning in the event of a fork to locate the keys for all the addresses in your wallet that have funds in them. I would start by getting a list of addresses with funds, which you can use to to sort out the keys that are useful. Go to the Accounts tab, click on the HD wallet, click the menu icon on the upper right, and click Show Unspent Outputs (aka UTXO). This will give you a list of all the addresses in your HD wallet that have funds in them. If you then have a long list of keys to sort through to figure out which ones have funds and which ones don't, the logical thing to do is generate the addresses from all those keys, and then sort that address list against your UTXO address list, just keeping the keys to the addresses that are on both lists. If the UTXO list includes addresses that aren't in the mnemonic converter list, then something went wrong, like you used the wrong derivation path or something. Mycelium's UTXO list is the primary reference.

What's wrong with just using Mycelium's 12 word seed as a backup? That is what it is designed for... Why do you want to use the xprv as your backup? ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) The 12 word seed is much easier to write down and type back in should you ever need to restore your wallet... plus, it backs up ALL the different HD "accounts" within Mycelium (if you have created multiple accounts)... Simply click the "3 dot" menu and select backup.

Simply click the "3 dot" menu and select backup. This isn't about backups, it's about how to split coins. If there's a fork, you have to import the private keys into a wallet that supports the forked coin. There are ancillary issues such as replay attacks, but that's not what we're talking about here. If the wallet for the forked coin has full HD functionality, then maybe you could fork your coins by doing a wallet restore on the forkcoin wallet. I haven't seen that, but then I haven't seen everything.

Mycelium uses BIP39 and BIP44... it uses a Derivation Path of m/44'/0'/0'/0 for receive addresses and m/44'/0'/0'/1 for change addresses (for the default account in Mycelium)... - Put 12 word seed into here: https://iancoleman.github.io/bip39/ (<insert standard warning about using offline copy here>) - Click BIP44 tab - See all your receive addresses AND private keys at the bottom at the bottom (generate as many as you need to find all your coins) - Change "External/Internal" value from 0 to 1 for change addresses - See all your change addresses AND private keys for those addresses at the bottom (generate as many as you need to find all your coins) The xprv and xpub are all generated from the seed... the 12 words are a less error prone method for representing the seed... For different "accounts" in Mycelium you can just increment the "account" part of the Derivation Path: m/44'/0'/1'/0 and m/44'/0'/1'/1 - Receive/Change for Account1 m/44'/0'/2'/0 and m/44'/0'/2'/1 - Receive/Change for Account2 etc If the wallet for the forked coin has full HD functionality, then maybe you could fork your coins by doing a wallet restore on the forkcoin wallet. I haven't seen that, but then I haven't seen everything.
You mean like how everyone could just restore their 12 word seed into Electron Cash to regenerate their Mycelium and/or Electrum wallets to access the BCC after the fork? ![Roll Eyes](https://bitcointalk.org/Smileys/default/rolleyes.gif) Personally, I'd rather write down (and double check) 12 words than attempt to make sure that I have transcribed something like: xprv9s21ZrQH143K2EQNBSLkWK1tSFmwprbUHff8sFGVmC4J4qMdJvNR2DVZyaaxA4kHS9hzx4fYtp2 HsXhqFW6UGuB15CotXZrF1uzikqX75nN correctly... but that is just me ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif)
