For example, it’ll take 17 years to make 30 guesses. When you enter the PIN code incorrectly, it increases the waiting time by a power of two. Its PIN code system ensures that brute-force entering is impossible. The primary highlight of Trezor One is its security. Some argue it’s the best Ethereum wallet in the market. This means even if you connect it with a compromised computer, you won’t face the risk of compromising your wallet. In terms of security, Trezor is quite advanced as its PIN code never leaves the wallet. It is a product of SatoshiLabs and has a straightforward interface.

In contrast to paper wallets produced by MyEtherWallet, the paper does not contain the unencrypted private key. Such paper wallet is just a backup with same security as backed up keyfiles on a normal USB stick. As shown in the following example, the paper contains the address (to not confuse multiple keyfiles/papers) and the keyfile in both plain JSON and QR-code. !!!And Note i am not responsible for any problems comming from this post!!!īased on Richard's answer I created a bash script to build a more readable paper backup. On the second picture: Search the function storeNewKey and call keyFileNamePlusPK inside the method. Uncomment tx (this is important) and expand the fmt.Sprintf command. On the first picture: Make a Copy of the function keyFileName and name it keyFileNamePlusPK. If the tests succeed, and you have the wallets printed out, erase the VM.Note: The paperwallets are save until the day you used the private key for the first time for a transaction.Test some of the paperwallets **with small amounts of money.

Note: The public key requires the prefix 0x to intend the usage as hex.

To create the paperwallets from the filenames, easily the list of the keystores can be written to a file with ls ~/.ethereum/keystore/ > paperwallet.txt and sent it to a printer.

Add 0x as prefix before the public key, because most programs expect it.

The private key and the public key is written in the filenames of the accounts in the keystore.
