After the Ethereum L2 competition heats up, Mantle is doing something else

From 2023–2024 in the L2 track, the essence is a race of performance and cost.
The differences between Arbitrum and Optimism are narrowing, with TVL relying more on liquidity migration and incentive rotation, and capital staying for shorter periods.
Mantle's choice is not to continue the "scaling race," but to elevate L2 from a "tool layer" to an "on-chain financial hub."
The core of financial competition has never been TPS, but the right to set rules.
Its logic involves three layers of barriers:
▪ Path Locking
▪ Interest Rate Dominance
▪ Settlement Monopoly
The goal is clear—to compete for the benchmark pricing authority of the on-chain financial system.
1⃣ Locking Capital Flows via Super Portal
Super Portal is not a traditional cross-chain bridge but a capital pathway controller.
After launching with Bybit and Byreal in January 2026, it will enable native cross-chain transfers of core assets between Ethereum and Solana, building a "capital tri-connection" network among the EVM ecosystem, high-TPS Solana markets, and CeFi.
It possesses three key capabilities:
1) Traffic Data Rights
Real-time control of cross-chain fund flows and risk preferences, providing foundational data for product design and incentive strategies.
2) Clearing Efficiency Advantage
Based on LayerZero OFT standard architecture, clearing efficiency improves by about 300%, reducing time to minutes.
3) Capital Guidance Ability
By adjusting fee and incentive ratios (e.g., providing 96,000 MNT incentives for the Solana MNT-USDC pool), directly influences supply and demand structures.
More importantly, it connects $4 billion in community assets with Bybit’s centralized liquidity, forming a CeDeFi closed loop.
Once the capital flow path becomes inertial, it becomes a structural advantage.
2⃣ Using Aave to Shift Interest Rate Rights from Protocol to Chain Layer
Aave is essentially an on-chain interest rate generator.
Deep cooperation with Mantle by the end of 2025 means interest rate rights will begin shifting from a single protocol to the chain layer.
Mantle’s approach is clear:
▪ Using mETH ($790 million TVL) and cmETH as underlying collateral
▪ Setting cmETH collateralization at 85% (higher than the usual ETH at 75%)
▪ Directly lowering the overall ecosystem capital cost
Coupled with Super Portal’s cross-chain clearing ability, it reduces liquidation failure risk and stabilizes the interest rate model.
Plus exclusive liquidity incentives, making Mantle a “rate haven.”
So far, Aave’s TVL in the Mantle ecosystem accounts for over half.
Once interest rates become the core attractor of the ecosystem, capital will naturally migrate to the “financial geographic center.”
3⃣ USDT0 + RWA, Competing for Clearing Sovereignty
Stablecoins determine the monetary base.
RWA determines asset growth.
Tether’s USDT0, using LayerZero OFT standard, enables native multi-chain circulation.
After partnering with Bybit for zero-fee deposits and withdrawals, it accounts for over 60% of circulation within the Mantle ecosystem, with 80% of RWA transactions cleared through it.
USDT0 becomes a unified clearing anchor.
Meanwhile, Mantle launched TaaS (Tokenization as a Service) platform, providing RWA on-chain solutions for traditional financial institutions.
Ondo Finance has deployed $29 million USDY (short-term government bond token).
Based on Aave’s interest rate model:
▪ Deposit interest rate 4.2%–4.5%
▪ Building risk hedges with pledged asset pools
The combination of “USDT0 + Aave + RWA” gives Mantle an advantage in on-chain clearing rights competition.
4⃣ Structural Differences Between Mantle and Traditional L2
⦿ Traditional L2:
Core: Scaling
Driven by: Incentive migration
Metrics: TPS, cost, EVM compatibility
Asset types: Native crypto assets
Scope of collaboration: On-chain
⦿ Mantle:
Core: Rule setting
Driven by: Capital sedimentation
Power structure: Path rights, interest rate rights, clearing rights
Asset types: Native assets + RWA + Re-staked assets
Scope of collaboration: CeFi – DeFi – TradFi
Utilizing OP-Succinct ZK Validium architecture and multi-token models, forming a “financial Lego” closed loop, enabling capital to circulate within the ecosystem rather than flowing out unidirectionally.
————————
From this, it’s clear that
Mantle is not competing for L2 market share.
It is competing for the benchmark position in on-chain financial order.
When paths are locked, interest rates are dominated, and clearing is unified, capital will form structural sedimentation.
$4 billion in community assets, $242 million in DeFi TVL, and over $1 billion in RWA assets are building a flywheel.
The real competition, the race for broader entry points, is just beginning.
