Decentralized finance (DeFi) explained

‍

In the landscape of modern finance, DeFi—or decentralized finance—emerges as a transformative force, leveraging the power of blockchain technology to recalibrate the way you engage with financial services. Gone are the days when transacting, borrowing, and investing required a traditional intermediary; DeFi operates on the sturdy shoulders of the Ethereum network, home to over 470 dApps, which account for 31% of the more than 1400 active dApps across all platforms⁶. As you immerse yourself into this vibrant ecosystem, you'll find that DeFi is not just about creating alternatives, but about reshaping the very nature of digital assets management and investment⁷.

This burgeoning sector dedicates itself to outstripping traditional financial constraints by exploiting smart contracts—the heartbeats of decentralized applications—which enforce and execute agreements on the blockchain with an unprecedented level of transparency and efficiency. Imagine a world where your investments, alongside a cumulative gross value that ranged from $78 billion to over $224 billion as of April 1, 2022, flourish without the boundaries of centralized systems⁶. Such is the promise of DeFi, a world where cryptocurrencies are not merely speculative instruments but cornerstones of a wide-ranging financial revolution.

Nevertheless, with great innovation comes responsibility. The high stakes of DeFi are underscored by the market volatility that saw a considerable decline in the value of DeFi products and services following the infelicities at Terra and Celsius⁶. As an aficionado of this digital paradigm, you must navigate through its complexities with acumen, aware of the risks of this highly speculative space⁷. Rest assured, as long as investor exposure to DeFi remains small, the systemic risks are considered minimal, sparing the world's financial stability from any significant tremors⁷.

DeFi's architecture is revolutionarily built on permissionless and decentralized constructs, intending to replicate and overhaul traditional financial services, placing you, the user, at the center of its universe. Its commitment to removing financial gatekeepers translates to a democratized platform where every action, from trading on decentralized exchanges to participating in investment schemes, resonates with the ethos of autonomy and empowerment⁷.

How to acquire and use wBTC

‍

Are you interested in leveraging the liquidity of Bitcoin within the expansive Ethereum-based decentralized finance (DeFi) platforms? Wrapped Bitcoin, or wBTC, acts as a bridge between these two leading cryptocurrencies, allowing Bitcoin holders to engage with DeFi applications. Launched as the first ERC-20 token backed by Bitcoin, wBTC ensures that each token is pegged 1:1 to Bitcoin, which means when you acquire wBTC, you're holding the equivalent value of Bitcoin wrapped on the Ethereum blockchain⁹.

Acquiring wBTC isn't a complicated process, but it does require you to go through a few steps to ensure security and compliance. Initially, you'll exchange your Bitcoin with a merchant who will then coordinate with a trusted custodian, currently BitGo, to mint wBTC tokens. This process ensures an accurate 1:1 peg between wBTC and BTC⁹. As of December 2020, the growing wBTC ecosystem has over 40 participants, including DAO members, wallets, merchants, and exchanges, setting a strong community foundation for wBTC transactions and enhancing trust and versatility¹⁰.

Once you have wBTC in your wallet, you can use it across various DeFi platforms which as of December 2020 include MakerDAO, Compound, Kyber Network, AAVE, Uniswap, and Balancer. These platforms allow you to use wBTC as collateral to borrow other digital assets, creating more financial opportunities¹⁰. Moreover, lending your wBTC in a pool on platforms like Compound can yield interest rates just below 3%, a number that outperforms many traditional banking offers¹⁰. Some protocols even incentivize this action by distributing governance tokens, for instance, Compound's COMP, for lending and borrowing, thus increasing potential profits¹⁰.

For those involved in more speculative pursuits, knowing that you can margin trade ETH, stablecoins, and various ERC-20 tokens using platforms like Fulcrum on the bZx protocol opens additional avenues to leverage your wBTC holdings¹⁰. Furthermore, with the emergence of decentralized exchanges (DEXs), you have the autonomy to trade your wBTC on platforms like Uniswap, without the need for a centralized cryptocurrency exchange to oversee the transactions. With DEXs, you're fully in control of your trades, providing a seamless and secure experience within the Ethereum ecosystem.

If you ever decide to revert back to Bitcoin, the process includes a 'burn' transaction where your wBTC is taken out of circulation, and Bitcoin is released back to you, ensuring the integrity of the 1:1 peg remains intact. This capability demonstrates the flexibility and fluidity between the two assets, with wBTC serving as a valuable instrument in the DeFi space and preserving its essential link to Bitcoin's market value⁹.
