In a striking development that underscores the maturing relationship between Bitcoin and decentralized finance (DeFi), the number of daily Wrapped Bitcoin (WBTC) transactions has doubled in the first four months of 2025, jumping from 6,800 on January 1 to an impressive 12,500 by April 28. This surge, confirmed by data published by Blockchain.News, signals a significant shift in how Bitcoin holders are deploying their assets within the DeFi ecosystem.
Once perceived purely as a “store of value,” Bitcoin is now being actively utilized within Ethereum-based DeFi protocols—thanks to WBTC, a tokenized version of Bitcoin built on the ERC-20 standard. As of Q2 2025, over 68% of all circulating WBTC is locked in decentralized finance platforms like Aave, Compound, and MakerDAO. This explosion in activity represents not only a vote of confidence in DeFi’s security and yield mechanisms but also a broader transformation in Bitcoin’s role in the crypto economy.
The rising adoption of WBTC hints at a critical turning point: institutional and retail investors alike are increasingly looking to diversify their BTC positions by earning yields, participating in governance, and leveraging collateralized debt positions (CDPs). In short, Bitcoin is no longer content to sit still—it wants to work.
Understanding Wrapped Bitcoin (WBTC)
Wrapped Bitcoin (WBTC) is an Ethereum-compatible token that represents Bitcoin at a 1:1 ratio. For every 1 WBTC in circulation, there is 1 BTC held in reserve by a trusted custodian—most notably BitGo. WBTC allows users to access DeFi applications without converting their Bitcoin into Ether (ETH) or other tokens. This cross-chain bridge has become a cornerstone of decentralized liquidity in 2025, facilitating billions of dollars in transactions each month.
According to CoinLedger and BitPinas, WBTC’s role in the DeFi ecosystem has steadily expanded over the past two years, primarily because it allows Bitcoin holders to engage in smart contract-based financial operations that were previously inaccessible.
How the Wrapping Process Works
The WBTC protocol operates through a system of custodians and merchants. Here’s how it works:
- A user sends Bitcoin to a custodian like BitGo.
- A merchant (such as Kyber Network or Ren) initiates the minting process.
- The custodian mints the equivalent amount of WBTC on Ethereum.
- WBTC can then be used in DeFi apps. When needed, users can burn the WBTC to redeem their original BTC.
Where WBTC Is Used
As of 2025, Wrapped Bitcoin is supported on nearly every major DeFi platform:
- Uniswap for decentralized swaps and liquidity provision
- Aave and Compound for lending, borrowing, and yield generation
- MakerDAO as overcollateralized backing for DAI minting
- Curve and Balancer for stable asset pooling and efficient trading
Market Momentum: Record Highs in WBTC Transactions
Data from Blockchain.News reveals that WBTC has seen a remarkable 84% increase in transaction volume since the beginning of 2025. From just 6,800 transactions per day in January to 12,500 by April 28, the token’s usage has reached new all-time highs—suggesting that more Bitcoin is flowing into DeFi protocols than ever before.
This increase aligns with a broader rise in DeFi TVL (Total Value Locked), which crossed the $150 billion mark in April 2025, with WBTC alone accounting for over $9.2 billion in locked value. In comparison, the same metric hovered around $4.8 billion at this time in 2024, showcasing a near 2x year-on-year growth rate.
Liquidity on decentralized platforms has surged in response. Curve Finance, one of the largest stable asset pools, reported a 67% increase in WBTC pairs, while Aave’s WBTC lending markets reached a new milestone of $2.5 billion in borrowed funds—up from just $1.1 billion in early 2024.
Moreover, analytics firm Messari notes that user behavior has also changed. Unlike in previous years, where most WBTC holders participated in short-term arbitrage or swaps, users in 2025 are increasingly engaging in long-term yield strategies, staking WBTC in vaults or using it to collateralize stablecoin issuance.
Motivations for Wrapping Bitcoin
The surge in Wrapped Bitcoin (WBTC) transactions in 2025 isn’t merely a statistical anomaly; it reflects a strategic shift among Bitcoin holders seeking to maximize their assets’ utility.
Unlocking Yield Opportunities
Traditionally, Bitcoin has been a passive asset, appreciated for its store-of-value properties. However, the advent of DeFi has introduced avenues for Bitcoin holders to earn yields without liquidating their positions. By wrapping BTC into WBTC, investors can participate in lending, staking, and liquidity provision, earning returns that were previously inaccessible.
Seamless Integration into DeFi Platforms
WBTC’s compatibility with Ethereum’s ERC-20 standard allows for seamless integration into a plethora of DeFi platforms. This interoperability means Bitcoin holders can now engage in complex financial activities such as yield farming and collateralized lending, expanding the functional use of their assets.
Diversification and Risk Management
Engaging with DeFi through WBTC also offers diversification benefits. By allocating a portion of their holdings into DeFi protocols, investors can spread risk and potentially enhance returns, all while maintaining exposure to Bitcoin’s price movements.
Primary Use Cases for WBTC in the DeFi Ecosystem
WBTC has become a linchpin in the DeFi ecosystem, serving multiple critical functions that enhance liquidity and enable complex financial operations.
Collateral for Lending and Borrowing
Platforms like Aave and Compound have integrated WBTC, allowing users to leverage their Bitcoin holdings as collateral for loans. This functionality provides liquidity without necessitating the sale of Bitcoin, preserving long-term investment positions.
Liquidity Provision in Decentralized Exchanges
WBTC is extensively used in liquidity pools on decentralized exchanges such as Uniswap and Curve. By contributing WBTC to these pools, users facilitate trading activities and earn a share of the transaction fees, effectively putting their assets to work.
Participation in Yield Farming
Yield farming strategies often involve WBTC, where users can stake their tokens in various protocols to earn additional rewards. This practice has become increasingly popular as investors seek to maximize the utility of their Bitcoin holdings within the DeFi space.

Protocols Driving WBTC Growth
The proliferation of WBTC is closely tied to its adoption by leading DeFi protocols, which have recognized the value of integrating Bitcoin’s liquidity into their platforms.
Aave and Compound
These lending platforms have been at the forefront of incorporating WBTC, enabling users to deposit WBTC and borrow other assets, or vice versa. The inclusion of WBTC has significantly increased the total value locked (TVL) in these protocols, reflecting heightened user engagement.
Uniswap and Curve
As major decentralized exchanges, Uniswap and Curve have facilitated WBTC trading pairs, enhancing market depth and liquidity. The presence of WBTC in these exchanges has attracted traders seeking exposure to Bitcoin within the DeFi ecosystem.
MakerDAO
MakerDAO’s acceptance of WBTC as collateral for minting DAI, a decentralized stablecoin, underscores the token’s growing importance. This integration allows Bitcoin holders to generate stablecoins without selling their assets, providing flexibility in portfolio management.
Security and Custody: Who Holds the Keys to WBTC?
In the evolving landscape of decentralized finance, the security and custody of Wrapped Bitcoin (WBTC) have become pivotal concerns. As WBTC bridges Bitcoin to the Ethereum network, ensuring the safekeeping of the underlying assets is paramount.
BitGo’s Multi-Jurisdictional Custody Model
BitGo, the primary custodian for WBTC, has implemented a multi-jurisdictional and multi-institutional custody framework. This model distributes the custody of Bitcoin reserves across various legal jurisdictions, enhancing security and reducing the risk of a single point of failure.
Community Concerns and Transparency Measures
Despite these measures, the crypto community has expressed concerns regarding the centralization of WBTC custody. The involvement of prominent figures in the crypto space has further fueled debates about the influence and control over WBTC’s governance.
