The blockchain landscape is evolving beyond simple scalability solutions. Layer 2 (L2) platforms are no longer judged solely by transaction speed or cost — they’re now being measured by how effectively they bridge the gap between decentralized finance (DeFi) and traditional finance (TradFi). At the forefront of this transformation stands Mantle, the fourth-largest L2 by Total Value Locked (TVL), which is redefining what it means to be a financial infrastructure layer in Web3.
With the recent unveiling of two groundbreaking products — Mantle Index Four (MI4) and Mantle Banking — Mantle is positioning itself not just as a scaling solution, but as a full-stack financial ecosystem designed to bring crypto into everyday life. This shift marks a pivotal moment in the narrative evolution of L2s, where technology becomes a vehicle for broader financial inclusion and institutional adoption.
The Rise of Mantle: Building a Multi-Chain Liquidity Hub
At its core, finance revolves around liquidity — the ability to move value efficiently. Mantle’s strategy over the past year has been laser-focused on maximizing capital efficiency through innovative yield-bearing assets that serve both retail users and institutional players.
Since its inception, Mantle has launched a suite of native financial instruments that have rapidly gained traction across chains:
- mETH: A liquid staking token introduced in December 2023, offering users over 6% annual yield while maintaining ERC-20 compatibility. Within a week of launch, mETH surpassed $100 million in TVL and peaked at $2.1 billion in 2024.
- cmETH: A liquid restaking token (LRT) launched in October 2024, allowing users to further leverage their mETH positions with native yield and composability across DeFi protocols.
- ƒBTC: Formerly known as FBTC, this fully composable Bitcoin yield asset was rebranded in February 2025 under the Function brand. Anchored 1:1 to BTC, ƒBTC enables seamless participation in cross-chain DeFi opportunities without sacrificing exposure to Bitcoin’s price appreciation.
These assets aren’t standalone experiments — they form the foundation of Mantle’s ambition to become a multi-chain liquidity hub. By designing tokens with built-in yield and high composability, Mantle ensures that value flows naturally across its ecosystem, increasing utility and demand.

Ecosystem Growth: Where Liquidity Meets Utility
Creating powerful assets is only half the battle. To sustain long-term growth, those assets must be embedded in real-use applications. Mantle has excelled here, cultivating an ecosystem of over 230 projects, including major names like Eigenlayer, Pendle, Solv, and Lombard.
Key highlights:
- mETH integrates with 42+ protocols, making it one of the most widely adopted LSDs on Ethereum.
- ƒBTC powers 28+ BTC-Fi integrations, fueling cross-chain liquidity with TVL surging from $270 million to $1.18 billion in just two months.
- The ecosystem also thrives on cultural momentum, with viral Meme projects and games like Catizen — a play-to-earn cat simulator attracting over 20 million registered users.
This blend of financial depth and community engagement has translated into measurable on-chain success:
- TVL grew from $340 million in January 2024** to **$2.36 billion at its peak, now stabilizing around $1.9 billion.
- Daily active users reached a high of 191,000, with total user count expanding nearly tenfold to 5.39 million by year-end.
Such metrics reflect more than speculation — they signal genuine user adoption and sustained activity within Mantle’s DeFi stack.
2025 Vision: Bridging TradFi and DeFi Through Innovation
As we step into 2025, Mantle is shifting from infrastructure builder to financial innovator. With regulatory tailwinds emerging in key markets and growing interest from traditional institutions, the timing couldn’t be better for a platform built on compliance, yield, and interoperability.
Mantle Index Four (MI4): A Gateway for Institutional Capital
One of the most anticipated launches of 2025 is Mantle Index Four (MI4) — an institution-grade, rules-based index fund designed to offer diversified exposure to digital assets including BTC, ETH, SOL, and USD-denominated stablecoins.
What sets MI4 apart?
- Regulatory compliance: Built to meet institutional standards for custody and reporting.
- Transparent rebalancing: Uses algorithmic rules to maintain target allocations, minimizing fees and human bias.
- Yield generation: Unlike passive ETFs, MI4 leverages Mantle’s native yield-bearing assets (like mETH and ƒBTC) to generate returns even during sideways markets.
- Scalable ambitions: Backed by Mantle Treasury — one of the largest in Web3 — MI4 aims to reach $1 billion in AUM shortly after launch.
For traditional investors hesitant about direct crypto exposure, MI4 offers a familiar investment vehicle with the upside of DeFi innovation. For existing crypto natives, it provides secure, diversified access to multi-chain assets within a regulated framework.
Mantle Banking: Your Unified Financial Dashboard
If MI4 opens the door for institutions, Mantle Banking aims to welcome everyday users into the world of on-chain finance.
Imagine a single account where you can:
- Deposit your fiat salary
- Instantly convert it into stablecoins
- Spend globally via a virtual card with sub-market transaction fees
- Earn yield on idle balances through integrated DeFi protocols
This is the promise of Mantle Banking — a DeFi-first banking experience that eliminates friction between fiat and crypto. By tokenizing real-world income streams and embedding them into programmable finance layers, Mantle makes crypto usable beyond trading and speculation.
More than just convenience, this model enhances capital efficiency. Funds that would otherwise sit idle in traditional bank accounts can now generate yield while remaining liquid for daily use.

Why $MNT Is More Than Just a Governance Token
As Mantle expands its financial offerings, attention turns to its native token: **$MNT**. Far from being a mere governance instrument, $MNT plays multiple critical roles across the ecosystem:
1. Native Gas Token
Unlike many L2s that rely on ETH for gas payments, Mantle uses $MNT as its primary transaction fee currency. This creates consistent, organic demand as network activity grows — turning every transaction into a value accrual mechanism for token holders.
2. No Future Token Unlock Schedule
One of the biggest concerns for investors in crypto projects is massive token unlocks that flood the market. $MNT stands out because all non-circulating tokens are held in treasury and managed via community voting, with no future public unlocks planned. This scarcity model supports long-term price stability and reduces sell-side pressure.
3. Mantle Rewards Station: Incentivizing Long-Term Holding
Users who lock $MNT in the **Rewards Station** earn “MNT Power,” which boosts their share of ecosystem incentives across various pools. Over **36,438 users** have already locked approximately **$128 million worth of MNT**, collectively earning over $10 million in rewards.
Crucially, locked tokens retain voting rights — aligning economic incentives with decentralized governance.
4. Backed by One of Web3’s Largest Treasuries
With over $4 billion in assets**, including $1 billion in blue-chip cryptocurrencies and equity stakes in leading protocols like Ethena and mETH, Mantle Treasury is among the most robust in the industry. In 2025 alone, it generated over $50 million in profits**, directly benefiting $MNT holders through buybacks, incentives, and strategic investments.
This treasury isn’t just a war chest — it’s a trustless engine driving sustainable growth.
Technical Foundations: ZK Rollups and Modular Architecture
Underpinning Mantle’s financial ambitions is a technically sophisticated stack designed for scale, security, and low cost.
Modular Design
Mantle separates core blockchain functions — execution, settlement, data availability — into distinct layers. This allows optimization at each level:
- Faster transaction processing
- Lower operational costs
- Enhanced flexibility for upgrades
EigenDA Integration
As the first L2 to adopt EigenDA, Mantle leverages EigenLayer’s restaking network to inherit Ethereum-level security while storing bulk data off-chain. This drastically reduces data publishing costs while ensuring high availability — essential for high-throughput financial applications.
Transition to ZK Rollups via SP1
In Q1 2025, Mantle began migrating from an Optimistic Rollup model to a ZK-based validity rollup using Succinct’s SP1 zkVM. This upgrade brings transformative benefits:
- Finality time reduced from 7 days to under 1 hour
- Near-instant cross-layer asset transfers
- Transaction costs as low as a few cents
- Stronger cryptographic guarantees for institutional trust
Combined with OP Stack modularity, this hybrid architecture positions Mantle as one of the most future-proof L2s for enterprise-grade finance.
