The decentralized finance (DeFi) landscape continues to evolve, and a major breakthrough has arrived from MakerDAO, the protocol behind the leading decentralized stablecoin Dai. In a significant move to expand cross-chain utility and deepen liquidity across the Ethereum ecosystem, MakerDAO has officially approved Wrapped Bitcoin (WBTC) as a new collateral asset.
This development means users can now leverage their Bitcoin holdings — long considered the crown jewel of cryptocurrencies — to generate Dai, opening new avenues for capital efficiency and DeFi participation without selling BTC. Let’s explore what this change means for users, how it works, and why it matters in 2025's maturing blockchain economy.
Why WBTC Matters for DeFi
Wrapped Bitcoin (WBTC) is an ERC-20 token that represents Bitcoin on the Ethereum blockchain, backed 1:1 by actual BTC reserves. By bridging Bitcoin’s value into Ethereum’s smart contract environment, WBTC enables Bitcoin holders to participate in DeFi protocols like lending, borrowing, and yield generation.
With MakerDAO’s integration of WBTC as collateral, Bitcoin is no longer just a store of value — it becomes a productive asset within one of DeFi’s most trusted financial systems.

This decision was made through decentralized governance: MKR token holders voted in favor of the proposal on May 3, marking another milestone in MakerDAO’s mission to create a truly open and accessible financial system.
According to the official announcement, “WBTC will help bring greater liquidity to the Ethereum and decentralized finance (DeFi) ecosystems, including decentralized exchanges (DEXs).”
How to Use WBTC to Generate Dai
Generating Dai using WBTC follows the same fundamental principles as other collateral types in MakerDAO’s Collateralized Debt Position (CDP) system. Here’s a step-by-step guide:
- Convert BTC to WBTC
To begin, users must convert their Bitcoin into WBTC. This process requires registration on platforms like CoinList, where users complete KYC verification before depositing BTC and receiving WBTC in return. - Transfer WBTC to a Compatible Wallet
Once obtained, WBTC can be sent to wallets such as MetaMask, Ledger, or Trezor — all of which support interaction with Ethereum-based DeFi applications. - Deposit WBTC into a Maker Vault
Using the Maker Protocol interface (like the Oasis app), users open a new vault and deposit WBTC as collateral. - Generate Dai Against Your Collateral
Based on the amount deposited and current risk parameters, users can draw Dai up to a certain limit while maintaining required collateralization ratios. - Manage and Repay Your Position
To close the position and reclaim your WBTC, simply repay the borrowed Dai plus any accrued stability fees.
This entire process empowers Bitcoin holders to access liquid capital without triggering taxable events or exiting their long-term BTC positions.
Key Risk Parameters for WBTC Collateral
The MakerDAO community established the following risk framework for WBTC through governance voting:
- Debt Ceiling: 10 million Dai
- Stability Fee: 1%
- Liquidation Ratio: 150%
- Minimum Dai Generation: 20 Dai per transaction
- Auction Lot Size: 1 WBTC per batch
- Minimum Bid Increase: 3%
- Auction Duration per Batch: 6 hours
- Maximum Auction Length: 6 hours
- Liquidation Penalty: 13%
These parameters are designed to balance accessibility with systemic safety. The relatively low stability fee makes WBTC an attractive option compared to higher-cost collaterals, while the 150% liquidation threshold ensures sufficient buffer against Bitcoin’s volatility.
Additionally, during the same governance vote, MKR holders agreed to reduce the stability fee for USDC to 0%, further enhancing capital efficiency across multiple asset types within the protocol.
Expanding Collateral Diversity: A Strategic Move
Integrating WBTC isn’t just about adding another token — it reflects MakerDAO’s broader strategy of diversifying its collateral base beyond purely Ethereum-native assets.
Currently, Dai is backed by a mix of crypto assets including ETH, BAT, and USDC. By incorporating WBTC, MakerDAO strengthens its resilience against market concentration risks and taps into Bitcoin’s massive market cap and holder base.
This move also aligns with growing demand for multi-chain interoperability and asset composability — core tenets of Web3’s future.
Frequently Asked Questions (FAQ)
Q: What is WBTC?
A: Wrapped Bitcoin (WBTC) is an ERC-20 token pegged 1:1 to Bitcoin. It allows BTC holders to use their assets on Ethereum-based DeFi platforms like MakerDAO.
Q: Can I use any type of wallet to interact with MakerDAO?
A: Yes, but your wallet must support Ethereum and ERC-20 tokens. Popular choices include MetaMask, Ledger Live, and Trust Wallet.
Q: Is there a risk of losing my WBTC?
A: As with any DeFi protocol, there are risks. If the value of WBTC drops below the liquidation ratio (150%), your collateral may be auctioned off. Always monitor your vault health.
Q: Why did MakerDAO lower USDC’s stability fee to 0%?
A: Reducing the fee encourages more users to generate Dai using USDC, improving liquidity and reducing borrowing costs across the system.
Q: How does adding WBTC benefit the wider DeFi ecosystem?
A: It brings Bitcoin’s liquidity into DeFi, enabling deeper markets, improved trading volumes on DEXs, and more diversified lending opportunities.
Q: Can I generate Dai with both WBTC and ETH at the same time?
A: Yes — you can open separate vaults for different collateral types, allowing you to optimize risk and reward based on market conditions.
The Bigger Picture: Bitcoin Meets DeFi
For years, Bitcoin has been seen as "digital gold" — valuable but largely inactive. MakerDAO’s integration of WBTC signals a shift toward making BTC a working asset in decentralized finance.

This development also sets a precedent for other protocols considering Bitcoin-backed financial products. As layer-2 solutions and cross-chain bridges improve, we may see even more direct BTC integrations in the future — potentially eliminating the need for wrapping entirely.
Moreover, this move enhances Dai’s credibility as a truly decentralized stablecoin. With multiple robust collateral options now available — including both volatile assets like ETH and WBTC, and stablecoins like USDC — Dai maintains its peg through diversified backing rather than reliance on any single asset.
Final Thoughts
MakerDAO’s approval of WBTC as collateral is more than a technical upgrade — it’s a strategic leap toward unifying two of crypto’s most powerful networks: Bitcoin and Ethereum.
By enabling users to generate Dai with Bitcoin-backed tokens, MakerDAO empowers holders to maximize utility without compromising on ownership. Whether you're a long-term HODLer or an active DeFi participant, this integration opens new doors for financial innovation.
As the DeFi space matures, expect more bridges between blockchains, richer collateral options, and smarter risk management tools — all driven by community governance and open access.
