Ethereum Classic is an open, decentralized, and permissionless public blockchain, that aims to fulfill the original promise of Ethereum, as a platform where smart contracts are free from third-party interference. ETC prioritizes trust-minimization, network security, and integrity. All network upgrades are non-contentious with the aim to fix critical issues or to add value with newly proposed features; never to create new tokens, or to bail out flawed smart contracts and their interest groups.
ERC20 Token Holdings Reseting in Trezor Ethereum Wallet
I recognize that Trezor's built-in ethereum wallet is in its beta stage, but I'm having to re-input the token addresses each time I log back in. I would like to have my various ERC20 token holdings saved so that I can monitor my holdings easily via the Trezor wallet. Is anybody else experiencing this issue?
Do I need to have my Trezor one connected to a computer to mine into the Trezor Ethereum Wallet?
Apologies if this is a dumb question, I am new to crypto. I want to use the Trezor Ethereum wallet to receive from ethermine, but do I have to leave the device connected at all times? And if not, do I need to send the ethereum keys from the Trezor ethereum wallet to the device? Does the trezor ethereum wallet function the same as etherwallet or is it just a way to interface with my trezor one? Thanks for any answers, Im a bit confused.
Hi - I have just bought a Trezor Wallet thinking I could store my ether on it and then realised that actually you seem to store it on my ether wallet.com but you use Trezor to log into it. What I wanted to check (and I'm a tech novice) is our my ether now stored physically on my Trezor wallet, as they would be with bitcoins, and I just use the MEW interface to check balances/send etc, or are they physically stored on MEW and I am just using the Trezor wallet as a sort of ultra secure way of signing in? I have no idea, and obviously if they are technically stored on MEW's servers are they less safe than if I had a ledger nano s which apparently stores them physically on the device (like Trezor does with Bitcoin). Any thoughts/advice much appreciated!
I know this may sound stupid but I’m double checking on the Trezor Ethereum wallet message I get when I’m transferring ETH from Coinbase to aTrezor. I just want to confirm that it’s official and correct and not some weird pop up or something. It presents differently then BTC or LTC transferring.
Hello, I am using the trezor ethereum beta wallet. By mistake I sent a transaction where the fee was too low. I read online that I can cancel the transaction by sending another transaction with 0 eth to myself which I did. The original transaction seems to be canceled but now when I try to move my eth, I get an error saying “nonce to low”…How can I fix this?
[How-To] Crafting an offline ERC20 TXN with the trezorlib python API
I've been working through some of the examples of the Trezor python library and finally got around to ERC20 stuff. I know there have been posts in the past asking about this so hopefully this will be useful. This is my third post about the rollout of v0.12.0 of trezorctl, and I know u/Crypto-Guide has done some nice videos as well. Here are the previous posts:
Since these examples cover ethereum, you will want to go through my previous trezorctl posts to ensure you install pip3 install trezor[ethereum]. I'll first show you how to craft the TXN using the console utility. Then we will create one directly in Python. What we will make is simply an exact copy of an existing TXN. Namely txn_id: 0xdcaf3eba...048e395b. This will use a Trezor loaded with the SLIP-0014 seed so you can follow along. ```
trezorctl ethereum sign-tx \
--chain-id 1 \ --address m/44'/60'/0'/0/0 \ --gas-limit 200000 \ --gas-price 5000000000 \ --nonce 11 \ --token 0xa74476443119A942dE498590Fe1f2454d7D4aC0d \ 0xA6ABB480640d6D27D2FB314196D94463ceDcB31e 5000000000000000 ``` You can check the resultant txn_hex with what is found on etherscan.io to ensure you produced the exact transaction. Please note, these input hex strings require EIP-55 compliance, so please don't chance the casing. Also, refer to EIP-155 for the various chain-id choices.
VIA Python API using trezorlib
The lower level python code is a bit more work, but you should only really need to change the block after CHANGE THESE. Just like the trezorctl example, this trezorlib example only produces the txn_hex it doesn't broadcast it. If you want to broadcast, you'll need to use the Etherscan PushTx page. ```
from trezorlib import tools, ui, ethereum from trezorlib import MINIMUMFIRMWARE_VERSION as min_version from trezorlib import __version_ as lib_version from trezorlib.client import TrezorClient from trezorlib.transport import get_transport from sys import version_info as py_ver, exit from rlp import encode as rlp_encode from web3 import Web3 from hashlib import sha256
Tested with SLIP-0014 allallall seed (slip-0014.md)

What if Trezor shuts shop, will we still be able to access our coins. Because we need the website to access the hardware wallet? Trezor has it’s own ethereum wallet, what if it stops supporting MEW, how would you access your coins that are behind the passphrase ?
Step by Step Instructions how to register/claim your EOS Tokens using TREZOR Hardware Wallet
Here it is… a follow-up instruction how I managed to register my EOS via MyEtherWallet and using the Trezor hardware wallet. BTW… EOS I bought from the Binance Exchange (recommended). Here is what you should do:
Buy EOS using different methods/exchanges - if you buy them from exchanges, no need to claim them.
Transfer them to your Trezor Ethereum Account using MyEtherWallet connection
Note: the address where you want to transfer your EOS to, needs to have some Ether on it…
Go to EOS.io and scroll down till you reach the “Get EOS” and click on it
Check all the 5 checkboxes (and read them if you want😊) and then hit “Continue”
Scroll down to “REGISTER” and click on it
Scroll down and choose “MyEtherWallet”
Than click on “GENERATE EOS KEYS”
You will be receiving a Public and a Private Key
Copy them to Notepad/Word for later use... Note: VERY IMPORTANT!!!! The better and safest way is to generate these keys OFFLINE using this site - https://nadejde.github.io/eos-token-sale/ - before you click on "Generate EOS Key" make sure your internet connection is off/down...so no malware/spy/hacker can see your Private Key (because this is what is important for them to have - the Krypto-rule says: who has the private key, has the coins!!). So you generate the keys offline, you write fast your Private key on a piece of paper and delete it right away from the computer! Then make 4-5 duplicates of it (on paper! no photo!) and keep them in 4-5 different locations safely. Before you connect again your computer to the internet, make sure you delete cookies and history files from your browser first!! You'll better use this alternative to be 100% safe. You don't want to put EOS in an address where a hacker has the private key of it and will steal your coins in the future when you expect the less :(.
Login to your Trezor, select Ethereum Account and go to MyEtherWallet site using Trezor
Give in your Passphrase if you have one (or the Trezor PIN code if requested… or both)
Make sure you have at least 0,1 Ether into your Wallet!!! If not… buy them from somewhere.
Go to “Contracts” and select the “EOS Contribution” contract
Hit “ACCESS” button
Scroll Down and go to “Select a function” and choose “Register”
In the KeyString you will have to put in the EOS Public Key you got above from EOS.io
Now you have to access MyEtherWallet again through Trezor – so choose Trezor and give in your PIN/Passphrase like usual
Then hit the “Unlock your Wallet” button
Press the “WRITE” button below
It will popup a Warning Message where you should click on “Generate Transaction”
Be aware: if you cannot go further because of an error message that says “Window blocked”, then you should enable first the PopUp into your Browser (so set it to not block popups!)
Then the Trezor Login will appear and you will have to login again with your Passphrase/PIN
You will have to confirm now 3 times in a row on your physical Trezor Device, using the Trezor right button
Then you will be prompted with another warning message that you will have to confirm “Yes, I am sure!” Notice: the gas should be above 90k and amount should be 0 (zero)!!
Now finally it comes a green message below that is says the transaction was successfully and will be soon confirmed
Then choose “Keys” from the pop-down menu
Give the MyEtherWallet address where you have your EOS tokens
Then hit the “READ” button
…and by the “String” you should see the EOS Public Key you received above from EOS.io / or generated offline yourself. So if you reached that point.. it means your EOS were being successfully registered and you're good! Now you can buy more EOS and send them to this "registered adress" - they will be "registered" automatically.
Hope I was clear and will be helpful for others who had same problem like I had.
How do you import a paper Ethereum address to a Trezor One?
So I have an Ethereum paper wallet, that is I have the address and private key of that Ethereum address written down on paper. I want to cash out the Ether. I am seeking the easiest way to send the Ether to some place to cash it out, like Coinbase. Can I do that, and if so, then how do I enter the private key in the Trezor so that I can then send the Ether?

Can't see ethereum balance for other wallets, if the first wallet has no transactions
I'm trying to use new Trezor Ethereum wallet. But I don't have any transactions or ETH on my first wallet and because of that I can't see next ETH wallets or do any operations with them. Hope you will fix that soon.
I'm wondering if it is still safe and protected to use m.e.w as a interface to buy and send ether to the trezor seeing as though no other coin makes you use third partying a little worried i think its just cause the block chains are different but im not sure and since it says you have to leave the trezor page to access the address I'm worried am I safe using it to buy a coin and send to one of the address on m.e.w and it will be in my trezor in a separate account I only have 1 account and 1 crypto on it rn so I'm wondering if it safe to do and were it will be in my trezor in account 1 or will it make a account 2 or do I just pick ether in the drop down and it be in one account
