Ethereum Classic

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.

Trezor/Ethereum/My Ether Wallet

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.

Recovering ERC-20 Po.et coins on Ethereum Classic Trezor using MEW

Hello, I'm hoping someone can help me. I mistakenly sent po.et erc20 coins to Trezor's Ethereum Classic address.
I tried adding Custom contract address for Po.et coin to Myetherwallet logged in to ETC node and it says invalid erc20. https://steemit.com/cryptocurrency/@niceviewsua/how-to-claim-your-po-et-tokens-29-08-17
I see the coins on the blockchain but I cant seem to access them to send to my Ethereum Wallet. https://etherscan.io/token/0x0e0989b1f9b8a38983c2ba8053269ca62ec9b195?a=0xf2c21c6caf80edabdc0e615e1f5bf6fa8aaff45c
Please help me solve. I will provide a bounty to someone who can help me.
Thanks!

Nonce To Low Error

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:
  1. Intro to trezorctl v0.12.0
  2. Crypto-Guide's Video intro to v0.12.0
  3. Into to Offline TXN signing API

VIA Console using trezorctl

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.
```

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 ?

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

Am I safe to ad ethereum to trezor

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
