Its architecture is described around ZK-Rollup, a decentralized oracle network, data availability, and Bitcoin-based fraud proofs, and the site also markets MERL and BTC staking programs.","category":"Finance & Markets","decision_record":{"best_for":"Bitcoin native-asset holders who want to use BRC20, Bitmap, Atomicals, Pipe or Stamp assets on an EVM-compatible L2, and EVM developers looking to build low-fee dApps with a grant pathway. Users seeking MERL or BTC-denominated staking yield are also targeted by the site.","not_ideal_for":"Users who need EIP-1559 fee mechanics, since the docs state there is no EIP-1559 support. Users seeking a guaranteed stable yield or maximum risk isolation should note that published yields are variable and that staking vouchers carry a documented approval-theft risk.","problems_solved":["Bitcoin L1 fees and limited scalability, addressed by an EVM-compatible L2 marketed for low fees and high scalability.","Limited utility for Bitcoin native assets, addressed by L2 support for BRC20, BRC420, Bitmap, Atomicals, Pipe and Stamp.","Transparency of L2 data transmission, addressed by a described architecture of sequencer data via decentralized oracles ","Access to BTC-denominated staking yield through phased Merlin BTC Staking programs.","A path for builders through the site's Build on Merlin and Apply for Merlin Grant actions."],"pricing":"Merlin Chain has no published subscription or price list; it earns through gas fees and yield-bearing staking programs. Docs describe two gas components — an L2 execution fee and an L1 security fee — but state that at the time of writing only the L2 execution fee was charged; cost is Gas Cost × Gas ","availability":"Web-based access via merlinchain.io, with Connect Wallet, Bridge, Stake, Unstake, Ecosystem, Agent, Docs and Tools. The organization is listed on LinkedIn as a partnership headquartered in Singapore.

Do not describe the product as free — it monetizes via gas and staking.
