AML check on Ethereum Classic

Ethereum Classic (ETC) is the original 2015 Ethereum chain, still running on proof of work. Its addresses look exactly like Ethereum addresses, so always check which network you are on.

Address format0x followed by 40 hexadecimal characters — the same format as Ethereum0x85a0f1bb782f4a04a13fa049085c6a66506b56efExample for illustration, not a real address.
Note

An ETC address uses the same 0x format as Ethereum, and the same address can exist on both chains with completely separate balances and histories. Make sure your AML checker is screening the Ethereum Classic chain, not Ethereum.

How to check an Ethereum Classic address

  1. Get the public addressAsk your counterparty for the address they will send from — or copy it from the incoming transaction.
  2. Pick a service that covers Ethereum ClassicChoose one marked “Supported” in the list above. Choose Ethereum Classic (ETC) explicitly in the checker. If it only offers Ethereum, the result describes that address's Ethereum history, not its ETC history.
  3. Run the check and read itCheck the exact address you will send from or receive to. The same seed phrase can produce different ETC addresses in different wallets (derivation path m/44'/61' vs m/44'/60').
A real AML check needs only a public address. Never share a seed phrase or private key.

Ethereum Classic specifics

  • Ethereum Classic is the original Ethereum chain launched in 2015. It kept running unchanged when Ethereum hard-forked in 2016 to reverse The DAO exploit.[1]
  • Ethereum Classic is a proof-of-work blockchain that runs the Ethereum Virtual Machine, uses the ETCHash mining algorithm (a modified Ethash), and has chain ID 61.[2]
  • EIP-155 introduced chain IDs in 2016 specifically so that transactions sent on Ethereum would not also work on Ethereum Classic (replay protection).[3]
  • ETC's total supply is capped at about 210.7 million coins under ECIP-1017, with block rewards reduced every 5 million blocks.[4]
  • The standard ETC wallet derivation path is m/44'/61'/0'/0/0. Wallets that use a different path can show different addresses from the same seed phrase, so ETC created in one wallet may not appear in another.[5]
  • Coinbase reported that from 5 January 2019 it detected repeated deep chain reorganizations of Ethereum Classic: 15 reorganizations, 12 of them containing double spends worth a total of 219,500 ETC (about $1.1 million at the time). Coinbase paused interactions with the ETC blockchain to protect customer funds.[6]
  • Coinbase reported two 51% attacks on Ethereum Classic in 2020: on 31 July (about 800,000 ETC, roughly $5.8 million, double-spent) and on 5 August (about 460,000 ETC, roughly $3.2 million). Coinbase said it was not targeted and lost no funds, because it significantly raised its ETC confirmation requirement so that no double-spend transactions were credited.[7]

FAQ

Is my Ethereum address also an Ethereum Classic address?

The format is identical (0x followed by 40 hexadecimal characters), so the same address can exist on both chains. But Ethereum and Ethereum Classic are separate blockchains, so balances and transaction histories are separate. Chain IDs (1 for Ethereum, 61 for ETC) stop a transaction signed for one chain from being replayed on the other.

What is a 51% attack, and has it happened on Ethereum Classic?

A 51% attack is when someone controls most of a proof-of-work network's mining power and rewrites recent blocks to spend the same coins twice. Coinbase reported about 219,500 ETC (around $1.1 million) double-spent in January 2019, and about 800,000 ETC and 460,000 ETC (around $5.8 million and $3.2 million) in attacks on 31 July and 5 August 2020.

Is there native USDT or USDC on Ethereum Classic?

No. Ethereum Classic does not appear on Tether's list of supported networks or on Circle's list of chains with native USDC (checked October 2026). A token on ETC that calls itself USDT or USDC is not one that Tether or Circle lists as its own.

How do I check a Ethereum Classic address for AML risk?

Copy the public address, open one of the services listed above that supports Ethereum Classic, and run the check. You never need a seed phrase or private key.

What does “Not verified” mean?

The service claims support somewhere — in marketing copy or a third-party page — but its own docs, pricing or FAQ do not list the network. Treat it as unknown.
