mETH Protocol, one of the top providers of liquid ETH restaking, has just announced a big upgrade that will make it easier and faster for people to get their ETH back. This upgrade uses Aave’s ETH market to improve how quickly people can redeem mETH. One of the most exciting parts of this update is the creation of a Buffer Pool that will allow people to get their ETH back in just 24 hours, depending on how much space is available in the buffer and the current network conditions. This is a huge improvement compared to Ethereum’s typical 5-20 day wait for people to take their ETH out of staking and for most liquid staking tokens (LSTs).
By adding ETH into Aave’s ETH lending market, the Buffer Pool will always be filled up and ready to go. This makes it possible to process large withdrawals very quickly and without any extra fees. At the same time, the mETH Protocol will still allow users to earn competitive ETH rewards and staking yields.
Ethereum has become a popular choice for companies and individuals who want to store digital assets, with ETH continuing to grow as a key asset. In fact, ETH spot ETFs saw a 65% quarterly growth in 2025, with net inflows rising from $6.2 billion to $10.2 billion. But as Ethereum’s popularity grows, it has caused some issues. For example, people trying to withdraw their ETH from staking have faced long waiting periods, with some withdrawal queues going past 40 days.
The mETH Protocol’s Buffer Pool upgrade solves this problem by offering two different ways to access liquidity:
Instant Buffer Pool: This is for smaller to medium-sized withdrawals.
Direct Access to Aave ETH Market Reserve: This is for larger withdrawals, especially those from big institutions.
This new system helps make sure that the redemptions happen quickly. It combines the liquidity from both systems to keep things flowing smoothly. The goal is for most redemptions to be processed within 24 hours. The mETH Protocol will use around 20% of its total value for the Aave reserve to create a blended yield that combines staking rewards and interest from Aave’s supply market. This means mETH can continue to offer good yields while also giving users a much better redemption experience.
The mETH Protocol’s upgrade shows that the platform is designed for large institutions that need to get their funds quickly, without giving up the ability to earn rewards. This makes mETH Protocol one of the most efficient platforms for institutional exit liquidity. The new system works with three key features:
Institutional-Grade Custody: Trusted partners like Fireblocks, Anchorage, Copper, and OSL provide secure custody to ensure everything is safe for large companies.
Minting mETH: Institutions can mint mETH directly within the custody platform and send it to exchanges like Bybit for trading. This makes it easier to trade and access liquidity.
Tier-1 Custodians and Validators: mETH Protocol also works with well-known custodians and validators to settle transactions smoothly.
These features make it easy for institutions to store their funds securely, access liquidity, and keep their operations running efficiently.
mETH Protocol is already a leader in ETH staking infrastructure, with over 40 Tier-1 DeFi app integrations, including Ethena Labs, Compound, and Pendle. The protocol has also contributed to major restaking networks like EigenLayer and Symbiotic. With this upgrade, mETH Protocol is becoming a more trusted source of ETH yield and continues to play a big part in helping both institutions and retail users get access to better liquidity.
This upgrade shows mETH Protocol’s growing role in the Ethereum staking ecosystem. It allows people to earn ETH rewards more easily while keeping everything secure.
mETH Protocol is a liquid staking and restaking platform built by Mantle, focused on giving institutional access to ETH yields while maintaining DeFi composability. In its first year, mETH Protocol locked $2.19 billion in value and works with top partners like P2P.org, Kraken Staked, OSL, and Copper. The protocol is used on over 40 DeFi platforms and exchanges like Bybit and Ethena, and is integrated into treasury systems for DAOs and large corporations to give them liquidity and yield.
