Frequently asked questions

Blender Wallet – is a cryptocurrency wallet, an interface for interacting with the blockchain. It does not store your funds, but offers an opportunity to manage it along with some useful features.

Yes, Blender Wallet is an HD wallet.

Blender Wallet is a non-custodial wallet. We do not store your mnemonic or your private keys. We do not have access to your funds. That's why if you lose your keys we won't be able to help you restore it.

An account – is your profile. It corresponds to your seed and your settings, not to the account in the HD wallet context.

Yes. Each wallet will have its own pair of extended keys, from which it will derive user's addresses. All of this pairs of keys derive from a master key and can be restored from it. Wallet is a Blender Wallet's implementation of the account in the HD wallet.

The Blender Wallet does not take any hidden fee. Reward is received only by miners for including your transaction to block.

Compatibility и Native SegWit.

To all types of addresses.

This option allows to subtract the amount of fee (network and mixer) from the transaction amount and to send the rest to the receiver.

By default the amount of fee is taken from the wallet balance and the receiver gets exactly how much you’ve specified in the Amount field.

If you mark your address as frozen the funds that lie on it will become unavailable for spending during an automatic transaction completion. You'll still be able to manually choose this address for spending in the Addresses tab but it will be marked with a snowflake label so that you can distinguish it from not frozen ones and not use it accidentally. It is a useful feature if for some reason you need to keep funds on the particular addresses untouchable.

A change address - is an address that is generated automatically for receiving a change when you create a transaction.

Yes, Blender Wallet allows you to manually choose addresses with unconfirmed coins for spend.

When using RBF, the initial transaction is replaced by a transaction with the same inputs and outputs. In order to increase miner’s fee, the amount of some of the outputs is being reduced. If the change amount is sufficient for that, than it’s being used, otherwise the amount of other inputs might decrease also. So, considering that, RBF is used when all of the following conditions are met:

1. Transaction is outgoing.
2. Transaction was marked with the RBF flag before sending.
3. Amount of transaction is sufficient to cover fee delta.

When using CPFP, one of the outputs of the unconfirmed transaction is being spent with high network fee. In order to do so, the transaction must either be incoming or be outgoing and have a change. So, considering that, CPFP is used when all of the following conditions are met:

1. RBF can not be used (conditions for RBF are not met).
2. Transaction has a change(in case it’s outgoing transaction) or it is an incoming transaction.
3. The unspent amount used is sufficient to cover the fee for the new(child) transaction.

Neither RBF nor CPFP can be used if:

1. Transaction is outgoing and
   • it was not marked with RBF flag or it’s amount isn’t sufficient to increase the fee.
   • it has no change or it's amount isn’t sufficient to be sent and pay for the new (child) transaction.
2. Transaction is incoming and it's amount isn’t sufficient to be sent and pay for the new (child) transaction.

You cannot discard a transaction if:
1. The transaction was not initiated by you, including if the transaction is incoming for you.
2. It has already been confirmed (has at least one confirmation).
3. The transaction was not marked with the RBF flag or its amount is not enough to increase the network fee.

Discarding a transaction might not succeed like any other RBF replacement. The initial transaction can be confirmed and the new one be rejected, if, for example, the miner takes the initial transaction into the block before the second appears in the network.

Please note that when a transaction is discarded, the entire amount will be returned to one address (all inputs will be combined).

A mixer - is a service that takes your coins and gives you other ones, unconnected with yours, therefore eliminating the connection between your transactions before and after using mixer.

The coins that you send go to our reserve where they go through the several stages of mixing with other coins. Meanwhile, previously mixed coins from our reserve that are not connected to yours are sent to the receivers you have specified.

A Guarantee Letter - is a text document that contains all the conditions of the mixing and our PGP signature. It is a proof of our obligations and it can’t be forged. You need to download it in order to provide it to us in case of any problems as a proof of our deal.

A delay — is the time by which the transfer of your result coins is deferred. The more time is passed between entering and exiting the mixer, the harder it is to relate your old coins to the new ones. Therefore it makes mixing more effective.

A Mixing Code is used to prevent you from receiving coins which you have sent to the mixer during previous usage(s). In other words, to prevent you from receiving your own coins. First time you use mixer in the wallet you can enter your own Mixing Code if you have one from the Blender.io. If you don’t a new one will be generated. After that code will be saved in your account and used each time you use mixer in the transaction.

Because we don’t keep any data that connects the sender and the receivers after the mixing is done.

No, this option is not supported yet.

For easy tracking of transaction statuses in Blender Wallet you can see next notifications:

- Incoming — appears when a new incoming transaction gets to the mempool.

- Outcoming — appears when a new outcoming transaction gets a first confirmation, i.e. gets into block.

- Rejected — appears when incoming or outcoming transaction gets rejected by the network, for example due to the replace by fee.
