Convert Zenrock BTC ZENBTC to Mantle Restaked Ether CMETH

zenBTC is a fully decentralized wrapped Bitcoin product with built-in native yield, that launched in early 2025. Positioned at the crossroads of two major ecosystems—wrapped Bitcoin solutions and liquid restaking tokens—zenBTC redefines Bitcoin interoperability and utility in DeFi. zenBTC leverages Zenrock’s proprietary distributed MPC (dMPC) technology to eliminate centralized control over locked Bitcoin. dMPC is an advanced security layer that gives users direct, permissionless control over their digital assets. While traditional MPC is a proven, institutional-grade cryptographic standard, dMPC represents the next evolution of this technology. It is fully decentralized and operates on-chain. With dMPC, key shards are distributed across a network of independent third-party node operators, ensuring that no single entity ever holds the complete private key. Only the initial user can make a key request and complete transaction signings. This eliminates risks associated with centralized custody and the need for institutional trust. When minting zenBTC tokens, deposited Bitcoin remains locked on the Bitcoin blockchain, untouched until zenBTC is redeemed. zenBTC’s dMPC security is underpinned by Zenrock’s native utility and governance token, $ROCK, which serves as the foundation of the entire Zenrock ecosystem.

Deployed on Ethereum layer 1 (L1) and governed by Mantle, mETH Protocol has, since late 2023, been providing users with access to $mETH, a value-accumulating receipt token that is highly composable across a range of DeFi applications on Mantle Network L2, offering exposure to additional yield-bearing opportunities. Users stake ETH with mETH Protocol and receive yield-bearing $mETH, and unstake $mETH to receive the underlying principal staked ETH and accumulated rewards. Since the inception of mETH Protocol, Mantle's mission has been to deliver the most user-friendly and rewarding $mETH experience. Thanks to ecosystem-wide adoption, $mETH users are able to trade on Mantle DEXs, earn yield by providing liquidity to $mETH liquidity pools, and generate yield within decentralized money markets. With $mETH's increasing adoption and composability within Mantle Ecosystem dApps, the protocol now ranks as the fourth largest ETH LSP by TVL. The introduction of $cmETH, a permissionless, composable liquid restaking token that unlocks restaking opportunities on Mantle, and $COOK, the protocol's upcoming governance token, mETH Protocol enters its next phase with further enhanced offerings. Through these features, mETH Protocol provides its users with capital efficiency, convenience, and a wide range of yield-bearing opportunities within Mantle Ecosystem dApps, all in a design that has been created to maximize security with non-custodial core smart contracts and off-chain services that enforce sanity bounds and risk limits.
