Bitcoin DeFi Takes Off as Ecosystem Explodes with Hundreds of New dApps

Over the last 15 years, Bitcoin has come to be known as “digital gold”, earning a thoroughly deserved reputation as an alternative store of value. But its potential goes well beyond that, and developments over the last few years have ignited a new wave of innovation around the world’s oldest cryptocurrency.

Bitcoin has long been hailed as “digital gold” thanks to its unique properties that make it an ideal store of value. But beyond this reputation, Bitcoin’s potential extends far into the realm of decentralized finance (DeFi). Recent years have seen a surge in innovation around the world’s oldest cryptocurrency, paving the way for a new wave of DeFi development.

At the heart of this convergence lies the ability to combine Bitcoin's massive liquidity, unrivaled security and over $1.2 trillion in largely idle capital with the transformative power of DeFi. This synergy alone makes Bitcoin DeFi a no-brainer, and it's already leaving its mark on the crypto world.

With the birth of hundreds of exciting new projects, ranging from Bitcoin-based decentralized exchanges (DEXs) like Velar Dharma and Sovryn to Bitcoin-focused lending protocols and native Bitcoin wallets like Xverse, a whole new ecosystem is rapidly taking shape.

Bitcoin’s Transformation: From Store of Value to DeFi Hub

Until recently, DeFi on Bitcoin was simply not possible. The infrastructure required to build decentralized financial applications atop Bitcoin’s blockchain did not exist. This is why DeFi flourished on Ethereum and, later, other blockchains like Solana and Avalanche.

The idea of creating a similar ecosystem on Bitcoin was largely dismissed, as its blockchain was deemed too rigid and, crucially, it lacked the ability to support the smart contracts needed to facilitate the wide-ranging functionality of DeFi applications.

However, the Bitcoin of old is no longer the Bitcoin of today. Starting with the introduction of Segregated Witness (SegWit) in 2017, it has evolved into a very different beast. SegWit did two key things: it helped to mitigate some of Bitcoin’s data limitations, and more importantly, it enabled the creation of so-called “Layer-2 networks”, such as Stacks, Rootstock and the Lightning Network.

With L2s, Bitcoin users are able to process transactions off-chain, increasing speed and reducing costs before ultimately settling them on the super-secure Bitcoin blockchain.

The next important milestone in Bitcoin’s evolution was the Taproot upgrade. Rolled out in November 2021, it paved the way for Bitcoin to support more complicated transactions and, later, the creation of Bitcoin-native smart contracts and dApps.

In a 2024 study, Coinmarketcap (CMC) Research and Footprint Analytics discussed how Taproot transforms Bitcoin into something far more powerful.

“Through Merklized Alternative Script Trees (MAST), Taproot condenses complex transactions into a single hash, reducing transaction fees and minimizing memory usage,” the report stated. “While not a DeFi solution itself, the Taproot upgrade improved Bitcoin’s smart contract capabilities, making it easier and more efficient to implement complex transactions and laying a foundation for future DeFi developments.”

It was because of Taproot that Bitcoin developer Casey Rodarmor was able to create the Ordinals and Runes protocols, which revolutionized the utility of Bitcoin. Introduced in 2023, Ordinals makes it possible to “inscribe” data such as an image or document onto a single satoshi, the smallest unit of Bitcoin, effectively transforming them into non-fungible tokens (NFTs) that live on the Bitcoin network.

Meanwhile, Runes enabled the creation of fungible tokens, equivalent to the ERC-20 tokens that live on Ethereum, giving rise to alternative, Bitcoin-based cryptocurrencies such as the Pepe memecoin and the Liquid Tether (L-USDT) and Sovryn Dollar (DLLR) stablecoins. Rodarmor’s efforts were quickly followed by the introduction of the BRC-20 standard, introduced by an anonymous developer called Domo, in March 2023.

Bitcoin DeFi Takes Off: A New Era of Innovation

The above developments unleashed a wave of innovation on the Bitcoin network, and the resulting DeFi ecosystem has become one of the fastest-growing segments in the crypto market, with over $560 million in total value locked as of October 2024.

Developers are striving to recreate the same kind of ecosystem that exists on Ethereum, driven by the desire to tap into the enormous value locked in Bitcoin, which accounts for more than 54% of the total capital in the crypto industry.

With the existence of a framework to follow in the shape of Ethereum’s DeFi space, developers have largely skipped the experimentation phase. Already, hundreds of Bitcoin-native dApps have launched, spanning everything from DEXs, stablecoins and NFTs, to lending and borrowing markets and “real-world assets”.

Velar itself has emerged as one of the biggest players in Bitcoin’s ecosystem. It has built a comprehensive decentralized exchange platform that enables seamless, low-cost swaps of Bitcoin-based tokens. Notably, it pioneered the very first perpetual DEX platform on Bitcoin, and provides a way for BTC holders to put their capital to work, providing liquidity in return for a share of the platform’s transaction
