What is Merlin Chain (MERL)? Learn About the Bitcoin Layer 2 Project Based on the ZK-Rollups Model

In 2024–2025, as Layer 2 solutions gain momentum, it’s not just Ethereum but also Bitcoin that’s being scaled through innovative technologies. One of the standout names catching the crypto community’s attention is Merlin Chain—a Layer 2 project built for Bitcoin that uses ZK-Rollups to take the Bitcoin ecosystem to the next level.
So, what is Merlin Chain, how does it work, and what makes it different? This article will walk you through the essentials of the project, the MERL token, and how it’s paving the way for DeFi, airdrops, and dApps to operate natively on Bitcoin—a capability that was previously limited.
As of now, the MERL token is trading at approximately $0.0944, with daily price fluctuations between $0.0942 and $0.0996. This recent performance reflects growing market interest as Merlin Chain gains traction. With its listing on Gate.io, users can easily track MERL’s real-time price, participate in staking, or explore early airdrop opportunities tied to the Bitcoin Layer 2 ecosystem.

What is Merlin Chain?

Merlin Chain is a Layer 2 scaling solution for Bitcoin, developed by Bitmap Tech (the team behind BRC-420 and Bitmap Protocol). It uses ZK-Rollups technology to compress transaction data on Layer 2 and post it back to Bitcoin’s Layer 1, preserving Bitcoin’s security and decentralization principles.
What makes Merlin Chain unique is its ability to enable Web3 applications, DeFi, NFT, and SocialFi to run on Bitcoin—similar to what Ethereum and Solana have done, but now built atop Bitcoin. This opens a new door for Bitcoin enthusiasts who also want to interact with modern dApps.

How Does Merlin Chain Work?

Merlin Chain leverages ZK-Rollups with three main components:

1. ZK-Rollup: Bundles transactions for lower fees and faster processing using zero-knowledge proofs.
2. Decentralized Oracle Network: A bridge to sync data between Layer 1 and Layer 2.
3. BTC Light Clients & Fraud Proofs: Ensures integrity and security during cross-layer interactions.

This infrastructure allows Merlin Chain to support smart contracts, staking, NFTs, and even airdrops—all on top of Bitcoin, with fast speeds and low costs.

What is the MERL Token?

MERL is the native utility and governance token of the Merlin Chain ecosystem. It is used for:

• Paying gas fees and interacting with smart contracts on Layer 2
• Participating in governance votes for protocol updates
• Staking and earning rewards through community programs

MERL has already been listed on major exchanges, including Gate, where users can buy, sell, stake, or track MERL prices in real time.

Its combination of scalability and Bitcoin’s inherent security makes Merlin Chain a promising foundation for low-cost, high-performance dApps.

Airdrop Opportunities and Early Engagement

With the rise of Layer 2 projects and retroactive airdrops, Merlin Chain is being closely followed by the airdrop hunter community. By interacting with the network early, staking, or using Merlin-based dApps, users may become eligible for potential airdrops.
On Gate, users can easily access Layer 2 tokens like MERL and stay updated on airdrop campaigns, retroactive reward events, and staking opportunities—all in one convenient ecosystem.

Conclusion

Merlin Chain represents a bold step forward in bringing Bitcoin into the era of DeFi and dApps, powered by cutting-edge ZK-Rollups. With strong development, innovative technology, and growing adoption, MERL could become a key player in the Layer 2 landscape of 2025.
