將 Amnis Staked Aptos coin STAPT 轉換為 Mantle Restaked Ether CMETH

stAPT is a vault designed to accrue the staking yield of the Amnis APT validators. At any time, amAPT can be exchanged for stAPT by depositing it into the stAPT vault, which allows users to earn staking yield on their amAPT. Over time, as validators accrue staking yield, an equivalent amount of amAPT is minted and added to the vault, allowing users to redeem their stAPT for a greater amount of amAPT than they deposited. The exhange rate of amAPT per stAPT increases over time as staking rewards are added to the vault. By holding stATP, you hold a % claim on an increasing amount of the vault's amAPT, splitting staking rewards up among stAPT holders proportional to their share of the total stAPT. This is similar to other autocompounding tokens like Aave's aUSDC and Compound's cUSDC.

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.
