Merlin Chain is emerging as a powerful Layer 2 (L2) network designed to extend the capabilities of Bitcoin by integrating cutting-edge technologies such as ZK-Rollup, decentralized oracle networks, data availability layers, and BTC fraud proof modules. By building atop Bitcoin’s secure foundation, Merlin Chain enhances the utility and interoperability of assets, protocols, and decentralized applications (DApps) that originate from Bitcoin’s Layer 1 (L1).
At its core, Merlin Chain leverages zero-knowledge proofs to validate transactions on the Bitcoin blockchain, enabling secure and transparent dispute resolution. This approach not only inherits Bitcoin’s unmatched security but also dramatically improves scalability and efficiency—making Merlin Chain a trusted environment for developers and users alike.
The vision behind Merlin Chain is clear: to bridge Bitcoin’s foundational innovations from Layer 1 to a more dynamic, scalable Layer 2 ecosystem. It supports a wide range of Bitcoin-native assets—including BRC-20 tokens—and fosters the development of fully on-chain decentralized applications in line with Bitcoin’s original ethos. With community-driven asset launches and full Ethereum Virtual Machine (EVM) compatibility, Merlin Chain expands Bitcoin’s use cases into DeFi, gaming, NFTs, and social platforms.
Launched in February 2024, Merlin Chain has rapidly gained traction, achieving over **$3.6 billion in Total Value Locked (TVL)**. It hosts a growing ecosystem of DApps across multiple verticals and introduces $MERL, its native token, which plays a central role in governance, security, and ecosystem incentives.
How Does Merlin Chain Work?
Merlin Chain is built using advanced blockchain infrastructure rooted in Polygon’s proven ZK technology stack. As a Layer 2 scaling solution for Bitcoin, it combines several innovative components to deliver high throughput, low fees, and robust security.
Zero-Knowledge Rollups (ZK-Rollups)
Merlin uses ZK-Rollups to bundle thousands of transactions off-chain and submit compressed cryptographic proofs to the Bitcoin network. These zero-knowledge proofs allow the mainchain to verify transaction validity without processing each one individually—dramatically reducing congestion and costs while maintaining security.
This architecture enables Merlin Chain to inherit Bitcoin’s consensus strength while operating at L2 speeds. Transactions are processed quickly and efficiently, then finalized on Bitcoin through trustless validation.
Decentralized Data Availability and Oracles
To ensure transparency and decentralization, Merlin integrates a decentralized oracle network powered by Celestia for data availability. This means all transaction data is published and accessible off-chain but remains verifiable by any participant. This setup prevents central points of failure and enhances censorship resistance.
Additionally, Lumoz provides decentralized computing power for generating zero-knowledge proofs (zkProver), distributing the computational load across a network of independent nodes. This further strengthens decentralization and reduces reliance on any single entity.
EVM Compatibility for Seamless Integration
One of Merlin Chain’s standout features is its EVM compatibility. Developers can deploy Ethereum-based smart contracts directly onto Merlin with minimal changes, lowering the barrier to entry and accelerating adoption.
This compatibility opens the door for existing DeFi protocols, NFT marketplaces, and Web3 tools to migrate or expand onto Bitcoin’s growing Layer 2 landscape—bringing liquidity, innovation, and user activity to the ecosystem.

MERL Token: Utility and Tokenomics
The native token of Merlin Chain is $MERL, a BRC-20 token with a fixed maximum supply of 2.1 billion units. This hard cap ensures scarcity and long-term value preservation, aligning incentives across the ecosystem.
Core Functions of $MERL
- Governance: Token holders can vote on key protocol upgrades, treasury allocations, and policy changes.
- Staking & Security: Users can stake $MERL to support network integrity and earn rewards.
- Transaction Fees: $MERL is used to pay for gas fees within the ecosystem.
- Collateral & Liquidity: The token serves as collateral in lending protocols and liquidity pools across Merlin-based DApps.
Phased Token Distribution
The $MERL token follows a carefully structured release schedule to ensure sustainable growth:
- A significant portion is allocated to the community through incentives, airdrops, and ecosystem grants.
- Development teams and early contributors receive tokens under multi-year vesting schedules.
- Treasury reserves fund future innovation, partnerships, and marketing initiatives.
This balanced allocation model promotes decentralization, discourages speculative dumping, and encourages long-term participation.
Key Features That Set Merlin Chain Apart
Merlin Chain stands out in the competitive Layer 2 landscape due to several defining characteristics:
✅ EVM Compatibility with Ultra-Low Fees
By combining ZK scaling with EVM support, Merlin delivers fast, low-cost transactions—ideal for microtransactions, gaming economies, and high-frequency DeFi interactions.
✅ Native Support for Bitcoin Protocols
Merlin natively supports popular Bitcoin asset standards like:
- BRC-20
- BRC-420
- Bitmap
- Atomicals
- Pipe
- Stamp
This deep integration empowers developers to build innovative applications leveraging Bitcoin’s expanding token ecosystem.
✅ ZK-Rollup Architecture for Scalability
With ZK-Rollups handling transaction batching and proof generation, Merlin achieves high throughput while minimizing data load on Bitcoin’s mainchain. Sequencer nodes coordinate transaction ordering, while decentralized oracles ensure data transparency.
✅ Community-First Innovation Model
Merlin prioritizes fair launches and community-led development. There are no pre-sales or VC dominance—instead, value flows directly to early adopters, contributors, and builders.
