The world of decentralized finance (DeFi) is undergoing a transformative shift as Bitcoin—long seen primarily as digital gold—begins to play a more active role in financial innovation. At the forefront of this evolution is DLC.Link, a pioneering protocol that enables Bitcoin holders to participate in Ethereum-based DeFi applications while retaining full control over their assets. Backing this groundbreaking initiative is OKX Ventures, the investment arm of OKX, one of the world’s leading cryptocurrency exchanges and Web3 technology companies.
This strategic investment marks a significant milestone in the journey toward a more inclusive, secure, and decentralized financial ecosystem—bridging the gap between Bitcoin’s unmatched security and the expansive utility of DeFi.
What Is DLC.Link?
DLC.Link is the first native Bitcoin cross-chain protocol built on Discreet Log Contracts (DLCs)—a smart contract mechanism that was made possible by Bitcoin’s Taproot upgrade in 2021. Unlike traditional bridging solutions or layer-2 networks, DLC.Link does not require modifications to the Bitcoin blockchain or reliance on third-party custodians.
Instead, it allows users to "self-wrap" their BTC into dlcBTC, a decentralized wrapped Bitcoin token, by locking their Bitcoin in a DLC. These contracts ensure that only the original depositor can withdraw the locked funds, eliminating counterparty risk and significantly reducing vulnerability to hacks, theft, or censorship.

The Security Advantage of Self-Custody
One of the most critical challenges in current cross-chain solutions is custodial risk. Most wrapped Bitcoin variants, such as wBTC, require users to deposit their BTC with centralized custodians. This introduces a single point of failure—exposing billions in value to potential breaches or regulatory intervention.
dlcBTC changes this paradigm entirely. By leveraging DLCs, the protocol ensures that:
- Users retain full custody of their Bitcoin at all times.
- Funds are protected through cryptographic guarantees rather than institutional trust.
- The system is inherently censorship-resistant, as no intermediary can block withdrawals.
This makes dlcBTC not just another wrapped asset—but a theft-proof, trustless alternative that aligns with Bitcoin’s original ethos of decentralization and user sovereignty.
How DLCs Work: A Technical Breakthrough
Discreet Log Contracts function as conditional payment agreements between parties, where outcomes depend on verifiable external data (orbits). In the context of DLC.Link:
- A user locks BTC in a multi-signature address shared with a dlcBTC Merchant (an institutional partner).
- An attestation network—comprising trusted node operators like OKX, HashKey Cloud, Republic, P2P, and Dextrac—monitors off-chain events (e.g., price feeds).
- When conditions are met, the attestation network signs a transaction that releases funds back to the user or mints dlcBTC on Ethereum.
- Crucially, only the original depositor can claim the BTC, ensuring asset safety even if other participants act maliciously.
Because DLCs operate natively on Bitcoin via Taproot, they inherit Bitcoin’s robust security model—without requiring new consensus rules or validator sets.
Why This Matters for Bitcoin and DeFi
Bitcoin holds over 50% of the total crypto market cap but accounts for less than 2% of total value locked (TVL) in DeFi. This underutilization stems from limited interoperability and reliance on custodial bridges.
dlcBTC aims to unlock this dormant value by enabling seamless access to Ethereum’s DeFi ecosystem—including lending platforms like Aave, decentralized exchanges like Uniswap, and yield strategies—without sacrificing decentralization.
As Aki Balogh, co-founder of DLC.Link, noted:
"wBTC has reached Top 15 token status despite its centralized custody model. In contrast, dlcBTC is the only wrapped Bitcoin that is minted from self-custody. DLCs enable a theft-proof wrapping mechanism without needing a bridge or L2 chain. dlcBTC has the potential to become a Top 10 token."
This vision aligns perfectly with OKX Ventures’ mission to support foundational innovations that expand blockchain’s real-world impact.

Its investment in DLC.Link underscores a strategic bet on native Bitcoin interoperability as a catalyst for broader adoption.
Dora Yue, founder of OKX Ventures, emphasized:
"DLC.Link is a pioneering project aimed at bringing the power and innovation of DeFi to the Bitcoin ecosystem, without compromising security, decentralization, or user experience. We are pleased to support their vision. OKX Ventures believes that DLC.Link will unlock more value within Bitcoin and help create a more open, inclusive financial system."
By supporting infrastructure-level innovations like DLC.Link, OKX Ventures reinforces its role as a key enabler of long-term structural growth in the blockchain industry.
Frequently Asked Questions (FAQ)
What makes dlcBTC different from other wrapped Bitcoins?
Unlike custodial versions such as wBTC or hbTC, dlcBTC is created through self-custody using Discreet Log Contracts. Your Bitcoin remains under your control at all times—no third party holds your funds.
Can anyone become a dlcBTC Merchant?
Initially, dlcBTC Merchants are vetted institutional partners with strong operational and security track records. Over time, the protocol may open participation to a broader set of validators.
Is DLC technology secure?
Yes. DLCs are built on cryptographic principles and leverage Bitcoin’s Taproot upgrade for enhanced privacy and efficiency. They have been peer-reviewed and tested in production environments.
Does using DLC.Link require trusting the attestation network?
No. The attestation network provides data but cannot access user funds. Even if all attesters collude, they cannot steal locked BTC—the protocol ensures only the depositor can reclaim it.
When will dlcBTC be available?
DLC.Link plans to launch dlcBTC in spring 2025, enabling Bitcoin holders to begin participating in Ethereum-based DeFi seamlessly and securely.
How does this affect Bitcoin’s decentralization?
Because DLC.Link operates natively on Bitcoin without altering its consensus or requiring sidechains, it preserves Bitcoin’s decentralization while expanding its utility.

The Road Ahead
The integration of Bitcoin into DeFi has long been considered the "holy grail" of blockchain interoperability. With DLC.Link and its dlcBTC token, that future is now within reach—not through compromises on security or decentralization, but through elegant cryptographic design.
As adoption grows and more developers build on top of this infrastructure, we may witness a new era where Bitcoin plays a central role not just as a store of value, but as an active participant in global financial markets.
For investors, builders, and users alike, the message is clear: the next phase of DeFi begins with native Bitcoin.
