AML check on Merlin Chain

Merlin Chain is a Bitcoin layer 2 that runs Ethereum-style smart contracts: addresses look like Ethereum's (0x...) and fees are paid mainly in bridged BTC.

Note

A Merlin 0x address can also exist on Ethereum and other EVM chains, so run the AML check on Merlin Chain itself. The BTC on Merlin is a bridged version of bitcoin, and the USDT and USDC listed in Merlin's docs are Merlin's Seal vouchers, not tokens issued by Tether or Circle.

How to check a Merlin Chain 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 Merlin ChainChoose one marked “Supported” in the list above. Pick Merlin Chain (chain ID 4200) in the checker. A result for the same address on Ethereum does not tell you what it did on Merlin.
  3. Run the check and read itIf funds came over from Bitcoin, check the Bitcoin source address too. Users who connect a Bitcoin wallet get a different 0x smart-account address on Merlin, so the two addresses will not match.
A real AML check needs only a public address. Never share a seed phrase or private key.

Merlin Chain specifics

  • Merlin Chain mainnet uses chain ID 4200, and its official network settings list BTC as the currency symbol.[1]
  • Merlin's docs say fees are paid mainly in bridged BTC (called Merlin_BTC), and MERL can also be used to pay fees from an AA (smart-account) wallet.[2]
  • According to Merlin Chain's milestone page, its mainnet went live on 8 February 2024.[3]
  • The official Merlin Bridge moves BTC, some BRC-20 tokens (such as ordi, sats and rats) and some Bitcoin NFT collections between Bitcoin and Merlin. The docs say a multi-signature wallet controls the bridge's owner role, and the bridge contracts can be upgraded.[4]
  • Custody provider Cobo announced in February 2024 that Bitcoin assets entering the Merlin bridge are held in an MPC wallet (one where the key is split between parties) managed jointly by Cobo and Merlin Chain, and that transactions are signed only after passing risk policies set by Merlin.[5]
  • The USDT and USDC in Merlin's token list are 'Merlin's Seal' vouchers (M-USDT and M-USDC), not tokens issued by Tether or Circle. The docs describe M-Tokens as 1:1 vouchers for assets staked in the Merlin's Seal event.[6]
  • Unstaking BTC from the Merlin's Seal event straight back to a Bitcoin address comes with a 72-hour processing period, according to Merlin's docs. Claiming it as M-BTC on Merlin takes 24 hours.[7]

FAQ

Is a Merlin Chain address the same as an Ethereum address?

It uses the same format: 0x followed by 40 hexadecimal characters. The same string can exist on both networks, but balances and transaction history are separate, so always check the address on Merlin Chain specifically.

What do I pay transaction fees with on Merlin Chain?

Merlin's docs say fees are paid mainly in bridged BTC (Merlin_BTC). MERL can also be used for fees from an AA (smart-account) wallet.

Is USDT on Merlin Chain issued by Tether?

No. Merlin Chain is not on Tether's list of supported networks or on Circle's list of native USDC networks. The USDT and USDC in Merlin's docs are Merlin's Seal vouchers (M-USDT and M-USDC).

How do I check a Merlin Chain address for AML risk?

Copy the public address, open one of the services listed above that supports Merlin Chain, 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.
