Question 1

What is Ethereum Classic (ETC)?

Accepted Answer

Ethereum Classic is the original Ethereum blockchain that maintained the unaltered transaction history after the 2016 DAO fork. It is a decentralized, Proof of Work smart contract platform with a fixed monetary policy capping supply at approximately 210.7 million ETC. ETC runs the Ethereum Virtual Machine (EVM), meaning it supports the same smart contracts and developer tooling as Ethereum and other EVM-compatible chains.

Question 2

How do I add ETC to MetaMask?

Accepted Answer

Open MetaMask, click the network dropdown, then "Add Network." Enter: Network Name: Ethereum Classic, RPC URL: https://etc.rivet.link, Chain ID: 61, Currency Symbol: ETC, Block Explorer: https://etc.blockscout.com. Alternatively, visit chainlist.org/chain/61 and click "Add to MetaMask" for automatic configuration.

Question 3

My transaction is stuck. What do I do?

Accepted Answer

A stuck transaction usually means the gas price was too low or there is a nonce gap. To fix it, send a new transaction with the same nonce but a higher gas price. In MetaMask, you can use the "Speed Up" button on a pending transaction. If that does not work, send a 0 ETC transaction to yourself with the stuck nonce and a higher gas price to clear the queue.

Question 4

How do I view my transactions on the blockchain?

Accepted Answer

Use the Blockscout explorer at etc.blockscout.com. Paste your wallet address in the search bar to see all transactions, token balances, and contract interactions. Each transaction shows the sender, recipient, amount, gas used, and confirmation status.

Question 5

How do I buy ETC?

Accepted Answer

ETC is available on major exchanges including Coinbase, Kraken, Binance, and OKX. You can also use decentralized exchanges like ETCswap directly on the ETC network. For fiat on-ramps, Brale offers ACH bank transfers to purchase ClassicUSD (USC), which you can then swap for ETC on ETCswap.

Question 6

Which wallets support Ethereum Classic?

Accepted Answer

Hardware wallets (Trezor, Ledger, SafePal), browser extensions (MetaMask), and mobile wallets (Trust Wallet, Exodus, Coinomi) all support ETC. MetaMask requires manual network configuration with Chain ID 61 and RPC URL https://etc.rivet.link. Hardware wallets provide the strongest security for long-term storage.

Question 7

What dApps are available on ETC?

Accepted Answer

The ETC ecosystem includes ETCswap (V2 and V3 decentralized exchanges), ETCswap Launchpad (token launch platform), Classic USD (USC stablecoin), WrappedEther.org (WETC), and Classic OS (economic dashboard). All approved dApps are listed on the Apps page at ethereumclassic.com/apps.

Question 8

Is there DeFi on Ethereum Classic?

Accepted Answer

Yes. ETCswap V2 and V3 provide automated market maker (AMM) functionality for token swaps and liquidity provision. Classic USD (USC) is a 1:1 USD-backed stablecoin on ETC. WETC (Wrapped ETC) enables ETC to be used in DeFi protocols that require ERC-20 tokens. Liquidity providers can earn trading fees by depositing assets into ETCswap pools.

Question 9

Can I stake ETC?

Accepted Answer

No. Ethereum Classic uses Proof of Work consensus, not Proof of Stake. There is no native staking mechanism. However, you can earn yield by providing liquidity on ETCswap — depositing token pairs into liquidity pools to earn a share of trading fees. This is sometimes called "liquidity mining" but it is fundamentally different from PoS staking.

Question 10

Has ETC been 51% attacked? Is it safe now?

Accepted Answer

ETC experienced 51% attacks in 2020, which led to the adoption of ECBP-1100 (Modified Exponential Subjective Scoring / MESS) as a temporary defense. MESS was later deprecated as the network hashrate grew significantly after Ethereum miners migrated to ETC following the September 2022 Merge. Current network hashrate makes 51% attacks economically prohibitive.

Question 11

How many confirmations do I need for ETC deposits?

Accepted Answer

Confirmation requirements vary by service. Most exchanges require 40,000+ confirmations for ETC deposits (approximately 6 days) as a security measure. For peer-to-peer transactions with known parties, 20-50 confirmations (~5-12 minutes) provides reasonable security. Higher-value transactions warrant more confirmations.

Question 12

What is gas on Ethereum Classic?

Accepted Answer

Gas is the unit measuring computational work required to execute transactions and smart contract operations on ETC. Every operation (sending ETC, interacting with contracts, deploying code) costs a specific amount of gas. You pay for gas in ETC at a price you set — higher gas prices incentivize miners to include your transaction faster. A simple ETC transfer costs 21,000 gas.

Question 13

What is the difference between ETC and ETH?

Accepted Answer

ETC and ETH share the same origin (the Ethereum launch in 2015) and the same virtual machine (EVM). They diverged in July 2016 over the DAO fork. Key differences: ETC uses Proof of Work, ETH uses Proof of Stake. ETC has a fixed supply cap (~210.7M), ETH has no hard cap. ETC has never performed an irregular state change. Both run the same smart contract languages (Solidity, Vyper) and development tools.
