What Is Merlin Chain?

Merlin Chain is a Bitcoin layer-2 network that aims to bring smart contracts and decentralized finance, often called BTCFi, to the Bitcoin ecosystem. It launched in early 2024 and was built by the team behind Bitmap Tech, a company associated with founder Jeff Yin. Rather than trying to replace Bitcoin, Merlin positions itself as a second layer that lets Bitcoin-native assets and their holders use faster, cheaper, programmable applications while still settling back toward Bitcoin. MERL is the network's native token, with a reported maximum supply of 2.1 billion tokens.

Technically, Merlin is an EVM-compatible chain that uses ZK-rollup technology. According to its documentation, it combines a ZK-rollup network, a decentralized oracle network, a data availability layer, and on-chain BTC fraud-proof modules. In practice this means transactions are executed off Bitcoin's base layer by Merlin's own sequencer, batched, and then committed with validity proofs, which is what lets the chain offer lower fees and higher throughput than transacting directly on Bitcoin. Because it is EVM-compatible, developers can port Ethereum-style Solidity contracts and tooling over to a Bitcoin-anchored environment.

A large part of Merlin's pitch is support for Bitcoin-native asset standards. The chain is designed to work with BRC-20 tokens, Bitmap, BRC-420, Atomicals, Pipe, Stamps, and other inscription-based protocols that emerged on Bitcoin, alongside native BTC itself. The idea is that assets minted on Bitcoin's Ordinals-era standards can move into a layer-2 setting where they can be traded, lent, or used as collateral, which is difficult or impossible on Bitcoin's base layer. This focus on Bitcoin-native assets is what distinguishes Merlin from general-purpose layer-2 networks that were designed around Ethereum.

To make BTC usable inside its DeFi applications, Merlin uses a wrapped representation of Bitcoin called MBTC. When you bridge BTC into the Merlin ecosystem, you receive MBTC, a token that is meant to be redeemable for the underlying Bitcoin and that can circulate through lending, trading, and yield protocols. This bridging-and-wrapping model is common across Bitcoin layer-2 networks, and it is also the single biggest source of risk to understand, because it introduces a custody and bridge layer between you and your actual Bitcoin. That risk is not hypothetical, and a real incident involving MBTC is covered in the section below.

It is worth being clear-eyed about where Merlin sits today. Total value locked on the chain is well below its 2024 peak, when Bitcoin layer-2 networks attracted a wave of deposits, and MERL trades far below its April 2024 all-time high. As of mid-July 2026, MERL's market capitalization was roughly 22 million dollars, with a circulating supply of around 1.3 billion tokens, according to market trackers. Figures like these move constantly, so treat any specific number as a snapshot rather than a fixed value, and check a live source before acting on it.

A note on terminology: because Merlin settles toward Bitcoin and relies on a ZK-rollup with its own sequencer, oracles, and fraud-proof modules rather than a standalone proof-of-stake validator set, it does not fit neatly into the "proof of stake" bucket that many independent chains use. Its security model is closer to that of other Bitcoin layer-2 designs, which is why this article tags it under a broader consensus category rather than labeling it a proof-of-stake chain.

Getting Started With Merlin Chain

Getting started with Merlin Chain generally means bridging assets in and connecting an EVM-compatible wallet:

  1. Step 1: Install an EVM-compatible wallet such as MetaMask or OKX Wallet, and add the Merlin Chain network using the parameters listed in Merlin's official documentation.
  2. Step 2: Acquire MERL from a cryptocurrency exchange, or bridge BTC and other supported assets into the Merlin ecosystem through the official bridge to receive their wrapped versions, such as MBTC.
  3. Step 3: Transfer your assets to your Merlin wallet and keep a small amount of the network's gas token on hand for transaction fees.
  4. Step 4: Explore the ecosystem cautiously. Understand that bridged assets carry bridge and custody risk, and start with small amounts until you are comfortable with how each application works.

How to Get a Merlin Chain Wallet?

Because Merlin Chain is EVM-compatible, most standard Ethereum-style wallets work once the network is added manually. Always confirm network details against Merlin's official documentation rather than trusting settings copied from third-party sites.

MetaMask

MetaMask is the most widely used EVM wallet and can connect to Merlin Chain once you add the network's RPC details. It works as a browser extension and mobile app, and it is a common starting point for interacting with Merlin's DeFi applications.

OKX Wallet

OKX Wallet is a multichain wallet that has supported Bitcoin layer-2 networks and Bitcoin-native asset standards. It can be a convenient option for users who want to hold both Bitcoin-side assets and EVM-side assets in one place while using Merlin.

Hardware Wallets

For meaningful balances, pairing a hardware wallet such as a Ledger with MetaMask keeps your private keys offline while still letting you sign Merlin transactions. Offline key storage is the sensible choice for anything beyond small, experimental amounts.

How to Buy MERL?

MERL is available on a range of cryptocurrency exchanges. As always, verify the current listings and trading pairs on the exchange itself before trading.

Centralized Exchanges

MERL launched across multiple exchanges in April 2024, including launchpools on Bybit and Bitget alongside listings on OKX, Gate, KuCoin, and HTX. It trades on major centralized exchanges such as OKX, Bitget, and Gate, typically against stablecoins like USDT. Binance offers MERL perpetual futures and an Alpha listing rather than a spot market. Availability and pairs vary by platform and region, so confirm before you buy.

Decentralized Exchanges

Within the Merlin ecosystem, MERL and wrapped assets such as MBTC can be traded on decentralized exchanges that run on the chain. Using a DEX on Merlin requires bridging assets in first and holding the network's gas token, and liquidity for any given pair can be thin compared with large centralized venues, which affects slippage on bigger trades.

Latest Merlin Chain News

The most significant event to understand about Merlin is MBTC's exposure to a third-party exploit in early 2025. In February 2025, an attacker used counterfeit "LBTC" tokens to borrow real assets from Ionic Money, a lending protocol running on the separate Mode Network, in what analysts described as a social-engineering attack that got the fake token listed as collateral. Several assets were affected, and MBTC was among the tokens that could be borrowed against the fake collateral on that platform. This was an exploit of a third-party protocol on another network, not a breach of Merlin Chain's own core infrastructure. Merlin responded by freezing the MBTC bridge on the Mode side, blacklisting the attacker's address, taking a pre-incident snapshot of MBTC holdings to help limit losses, and stating that MBTC collateral itself was safe. The episode is a useful reminder that wrapped Bitcoin assets can be put at risk by the third-party applications they are deposited into, even when the issuing chain is not itself compromised.

More broadly, Merlin sits in a Bitcoin layer-2 sector that has cooled considerably since the 2024 enthusiasm. Total value locked across these networks, Merlin included, is well off its peak, and MERL's market capitalization of roughly 22 million dollars in mid-2026 reflects that retrenchment. The core risks to weigh are the ones common to all bridge-and-wrap Bitcoin layer-2 designs: your BTC becomes a wrapped IOU that depends on the security of a bridge and its custody arrangements, and on the individual applications you use. The takeaway is to treat Merlin as an experimental, higher-risk environment, keep only what you can afford to lose in bridged form, verify every network setting and link against Merlin's official documentation, and check live market data before making any decision.
