Bybit, the world’s second-largest cryptocurrency exchange by trading volume, has unveiled its mETH Boosted Yield Campaign on Bybit On-Chain Earn, in partnership with Mantle and mETH Protocol. The promotion offers a fixed 3% Bonus APR on newly minted mETH, running from Dec. 16, 2025, to Feb. 15, 2026, coinciding with the rollout of the mETH Buffer Pool Upgrade.

Faster Ethereum Liquid Staking

The upgraded Buffer Pool architecture aims to cut redemption times to roughly 24 hours, making mETH a faster, more flexible Ethereum-native yield instrument. Participants can stake ETH to mint mETH directly on the Bybit platform without external wallets, cross-chain transfers, or manual delegation, streamlining the staking process for retail and institutional users alike.

During the campaign, all new mETH minted through Bybit On-Chain Earn earns the 3% Bonus APR on top of standard staking yields. The Buffer Pool also introduces enhanced liquidity, addressing a common bottleneck in Ethereum staking where unstaking can take days to weeks.

mETH: High-Yield, Flexible Collateral

mETH is the receipt token issued via the Mantle Liquid Staking Program. Its upgraded Buffer Pool leverages a dynamic liquidity model supported by Aave, enabling near-immediate withdrawals under normal conditions. Additionally, mETH can be used as collateral within Bybit Unified Trading Accounts, allowing stakers to continue trading while earning staking rewards.

Eligibility is calculated via hourly balance snapshots, with daily eligible amounts based on the lowest balance within a 24-hour window. Main Accounts and Subaccounts—including Funding, Trading Bot, and Unified Trading Accounts—qualify, while certain uses such as Crypto Loans or Copy Trading Pro Subaccounts are excluded. Bonus rewards are distributed daily to users’ Funding Accounts.

Strategic Implications

The mETH Boosted Yield Campaign signals Bybit’s ongoing push to expand liquid staking offerings and improve capital efficiency and liquidity for Ethereum participants. By integrating institutional-grade on-chain yield solutions with a centralized platform, Bybit continues to blur the line between DeFi-style staking and traditional trading infrastructure, offering both convenience and flexibility for users.
