The blockchain landscape is evolving rapidly. While Ethereum remains the dominant force in DeFi, a new generation of Layer 1 blockchains is emerging—chains like Reef, Monad, Celo, and others that offer unique value propositions but lack the mature DeFi infrastructure that users have come to expect.

For these emerging ecosystems, the question isn't whether they need lending protocols—it's which ones they should deploy first.

At Mosaic Protocol, we believe the answer is clear: Liquity v1 is the ideal lending primitive for nascent blockchain ecosystems. Here's why.

Every healthy DeFi ecosystem needs a few core primitives to function:

• Decentralized exchanges for token swaps

• Lending protocols for capital efficiency

• Stablecoins for price stability and unit of account

Without lending infrastructure, users can't leverage their assets. They can't access liquidity without selling. They can't participate in sophisticated DeFi strategies. The ecosystem stagnates.

But not all lending protocols are created equal—especially for chains still finding their footing.

Liquity v1's design is elegantly simple: users deposit ETH (or the native chain token) as collateral and borrow a stablecoin against it. That's it.

No multi-collateral complexity. No governance tokens deciding risk parameters. No oracle dependencies beyond price feeds. Just a proven, battle-tested mechanism that works.

For emerging chains, this simplicity is transformative:

Liquity v1 has been live on Ethereum since April 2021, processing billions in volume without a single security incident. The codebase is thoroughly audited, well-documented, and has survived the ultimate stress test: production use during multiple market crashes.

When you're building on a chain with limited developer resources and auditing capacity, starting with proven, minimalist architecture dramatically reduces your attack surface.

Multi-collateral lending protocols require:

• Sophisticated oracle networks for every supported asset

• Governance mechanisms to manage risk parameters

• Complex liquidation systems that can handle diverse collateral types

• Significant computational overhead

Liquity v1 requires:

• A price feed for the native asset

• Smart contracts that have already been tested extensively

For chains still developing their infrastructure, this difference is critical. You don't need a mature oracle ecosystem. You don't need active governance participation. You need something that works, reliably, from day one.

Liquity v1's 110% minimum collateral ratio is the most capital-efficient design in DeFi lending. Users can access up to 90.9% of their collateral's value—far higher than the typical 50-75% offered by other protocols.

For emerging chains trying to bootstrap liquidity, capital efficiency matters. Every dollar of TVL counts. Liquity v1 makes those dollars work harder.

Liquity v1 charges no ongoing interest. Users pay a one-time borrowing fee (typically 0.5%) and that's it. No accruing debt. No surprise liquidations from rate changes. No complex interest rate models to manage.

This creates a frictionless user experience that's easy to understand and easy to adopt—crucial for onboarding users to a new chain.

Liquity's stability pool mechanism for liquidations is genuinely decentralized. There's no reliance on external liquidators or keeper bots that might not exist yet on your chain. The protocol handles liquidations internally, ensuring system stability regardless of ecosystem maturity.

While Liquity v1 originally launched with LUSD (a USD-pegged stablecoin), the architecture is flexible. At Mosaic, we're launching with MEUR—a Euro-pegged stablecoin.

Why?

Because stablecoin markets are dominated by USD, leaving massive opportunities in other currencies. The European market is underserved, yet represents one of the world's largest economic zones. Emerging chains are the perfect place to experiment with non-USD stablecoins because they aren't yet locked into USD-centric DeFi infrastructure.

MEUR gives European users, businesses, and institutions a decentralized way to access EUR-denominated credit without traditional banking intermediaries. It's a natural fit for chains like Reef that are building compliance-ready infrastructure for alternative investments.

Liquity v2 brings exciting innovations: multi-collateral support, interest-bearing assets as collateral, dynamic stability fees, and enhanced liquidation mechanisms.

These are powerful features—for mature ecosystems.

But for emerging chains, v2's complexity creates more problems than it solves:

• Multi-collateral requires diverse, liquid markets that don't exist yet

• Dynamic interest rates add complexity users may not understand

• Additional governance demands active community participation

• Higher computational requirements may strain network capacity

You can always upgrade to v2 features later. But you can't undo a failed launch because you chose complexity over reliability.

Here's our recommendation for emerging chains:

Phase 1: Deploy Liquity v1

• Launch with native token collateral (e.g., REEF → MEUR)

• Establish the lending primitive users need

• Build TVL and user base with proven mechanics

Phase 2: Optimize

• Add staking derivatives (stREEF, etc.) as collateral

• Integrate with other DeFi protocols

• Explore chain-specific optimizations

Phase 3: Expand

• Selectively adopt Liquity v2 features that make sense

• Add multi-collateral support as markets mature

• Evolve based on actual user needs, not theoretical ones

This is exactly the path Mosaic Protocol is taking on Reef Chain.

The next 12-24 months will be critical for emerging L1s. Chains that build robust, reliable DeFi infrastructure will attract users and capital. Chains that over-complicate or launch broken protocols will struggle.

Liquity v1 gives you the foundation to succeed. It's proven, secure, capital-efficient, and simple enough to deploy quickly.

For Mosaic, it's the perfect starting point as we build towards becoming the Alternative Investment L1—bringing tokenized real estate, sports club equity, and other real-world assets on-chain with the compliance and infrastructure these markets demand.

And it all starts with getting the basics right.

Mosaic Protocol is launching on Reef Chain testnet in late February 2026. We'll be the first Euro-pegged stablecoin built on Liquity's battle-tested architecture, deployed on one of the most promising emerging L1s.

The future of DeFi isn't just on Ethereum. It's on every chain that gets the fundamentals right.

Mosaic Protocol is building the lending infrastructure for Reef, the Alternative Investment L1. Starting with MEUR on Reef Chain, we're creating the foundation for compliant, tokenized access to real-world assets.
