Bitcoin, the world’s first and most valuable cryptocurrency, has long been regarded as digital gold—a store of value locked away in cold wallets and long-term holdings. But beneath this static perception lies a transformative shift: Bitcoin is evolving into a dynamic financial asset, fueling a new wave of decentralized finance (DeFi) innovation known as BTCFi.
With over $1 trillion in market capitalization, Bitcoin represents the largest and most secure asset pool in the crypto ecosystem. Yet, an estimated 95% of BTC remains idle, generating no yield and contributing little to on-chain economic activity. That’s beginning to change. Through innovative protocols like Avalon Labs, Bitcoin is being reimagined—not just as a reserve asset, but as the foundation for a global, yield-generating liquidity network.
The Untapped Potential of Bitcoin Liquidity
According to DeFiLlama, Ethereum’s total value locked (TVL) surpassed $64 billion by early 2025—up nearly 180% from 2023. Meanwhile, despite Bitcoin’s superior market performance and growing ecosystem momentum fueled by Ordinals and BRC-20 tokens, its on-chain DeFi activity lags significantly behind.
This gap represents one of the biggest opportunities in crypto today.
Even a 10% release of Bitcoin’s dormant liquidity could unlock $180 billion** in capital. If Bitcoin were to achieve a similar TVL-to-market-cap ratio as Ethereum (~16%), that number jumps to **over $300 billion—potentially making BTCFi the largest DeFi ecosystem by value.

Protocols like Avalon Labs are at the forefront of this transformation. As the largest Bitcoin-native lending platform, Avalon has already achieved over **$2 billion in TVL**, positioning itself just behind DAI and lisUSD in the broader DeFi landscape. Its stablecoin, **USDa**, reached $500 million in locked value within just one week of launch—an unprecedented growth rate in DeFi history.
But what makes Avalon different? It's not just about scale. It's about accessibility.
Unlike traditional DeFi platforms dominated by whales and institutional players, Avalon is designed for retail participation. By offering a fixed 8% yield on BTC-backed loans and infinite supply of USDa, it empowers everyday holders to leverage their assets safely and efficiently.
How BTCFi Is Reshaping Decentralized Finance
The rise of BTCFi marks a paradigm shift: from passive ownership to active financial engagement.
Historically, Bitcoin holders faced a dilemma. To participate in DeFi, they had to wrap their BTC—often through centralized bridges—exposing them to counterparty risk and fragmentation across chains. Now, native Bitcoin lending protocols are enabling non-custodial, chain-agnostic liquidity solutions that keep BTC secure while unlocking its utility.
At the heart of this evolution is the concept of structured yield—turning static BTC into income-generating collateral without sacrificing security.
Avalon exemplifies this model with four core components:
- A Bitcoin-backed stablecoin (USDa)
- A decentralized lending protocol
- A hybrid CeDeFi borrowing platform
- A BTC staking-enabled lending layer
This multi-layered approach bridges CeFi efficiency with DeFi transparency, allowing users to borrow stablecoins against their BTC without selling it—effectively monetizing their holdings.
Moreover, thanks to cross-chain interoperability via LayerZero, USDa can be used seamlessly across EVM-compatible networks like Arbitrum, Base, and Optimism—without relying on third-party bridges. This eliminates major points of failure while expanding Bitcoin’s reach beyond its native chain.
Why Bitcoin-Based Stablecoins Matter
Stablecoins are the lifeblood of DeFi. Today, most are built on Ethereum using over-collateralized debt positions (CDPs), with MakerDAO’s DAI leading the pack. These systems allow users to lock up crypto as collateral and mint dollar-pegged tokens—functionally equivalent to a loan.
Bitcoin was historically excluded from this system due to technical limitations. But new infrastructure is changing that.
USDa operates on a similar CDP model but with key advantages:
- Bitcoin-first design: Uses native BTC as collateral
- Fixed interest rate: Predictable 8% borrowing cost
- Infinite minting capacity: No artificial supply caps
- Cross-chain usability: Operates across multiple ecosystems
This combination addresses two longstanding issues in BTCFi:
- The lack of a truly decentralized, Bitcoin-native stablecoin
- The fragmentation of liquidity across isolated chains
By integrating CeFi liquidity providers into its hybrid lending platform, Avalon also solves the USDT peg challenge—allowing users to convert USDa into widely accepted stablecoins instantly.
In essence, USDa isn’t just another stablecoin. It’s a liquidity rail for Bitcoin, enabling holders to access capital markets without exiting their positions.

The Road Ahead: Building a Sustainable BTCFi Ecosystem
For BTCFi to reach its full potential, three pillars must align: security, scalability, and user adoption.
Security comes naturally with Bitcoin’s proven consensus mechanism. Scalability is being addressed through layer-2 innovations and cross-chain messaging protocols. But adoption hinges on making these tools accessible—not just to developers and whales, but to millions of retail investors worldwide.
Avalon’s focus on inclusive design sets a precedent. By prioritizing small holders and simplifying complex financial mechanics, it lowers the barrier to entry and fosters organic growth.
Other projects like Babylon and Solv are contributing to this ecosystem by introducing novel concepts such as liquid staking for PoS chains using BTC as collateral and BTC-backed derivatives. Together, they’re forming a rich tapestry of financial primitives centered around Bitcoin.
We’re no longer talking about isolated experiments. We’re witnessing the birth of a self-sustaining financial layer, where Bitcoin serves not just as money, but as the base asset for loans, yield strategies, synthetic assets, and more.
Frequently Asked Questions (FAQ)
Q: What is BTCFi?
A: BTCFi refers to decentralized financial applications built around Bitcoin. It enables BTC holders to earn yield, borrow stablecoins, stake assets, and participate in DeFi without giving up custody.
Q: How does Bitcoin lending work?
A: Users deposit BTC as collateral and borrow stablecoins like USDa. The loan is over-collateralized to ensure safety, and interest rates are fixed or algorithmically adjusted depending on the protocol.
Q: Is it safe to use my BTC as collateral?
A: Yes—if you use reputable, non-custodial protocols with strong security audits and liquidation safeguards. Always understand the risks of volatility and margin calls.
Q: What is USDa?
A: USDa is a decentralized stablecoin issued by Avalon Labs, backed entirely by Bitcoin collateral. It offers fixed-rate borrowing and seamless cross-chain functionality.
Q: Can I use Bitcoin-based stablecoins on other blockchains?
A: Yes. Thanks to interoperability protocols like LayerZero, assets like USDa can be used across EVM-compatible chains without relying on centralized bridges.
Q: Why hasn’t Bitcoin been widely used in DeFi until now?
A: Bitcoin’s original design prioritizes security over programmability. Recent advancements in sidechains, Layer-2s, and cross-chain tech have finally unlocked its potential for DeFi integration.
The era of idle Bitcoin is coming to an end. With protocols like Avalon leading the charge, we’re entering a new chapter where Bitcoin becomes not just held—but actively used.
This isn’t speculation. It’s already happening.
As more users realize they don’t have to choose between holding BTC and earning yield, the floodgates will open. The result? A trillion-dollar liquidity layer built on the most trusted asset in digital history.
