## What Is dlcBTC (DLCBTC)?

dlcBTC is a non-custodial representation of Bitcoin on the Ethereum blockchain, developed by DLC.Link. Officially launched in February 2024, dlcBTC enables Bitcoin holders to engage in decentralized finance (DeFi) activities on Ethereum without giving up ownership of their assets. This trust-minimized bridge utilizes Discreet Log Contracts (DLCs) for secure and private transactions between Bitcoin and Ethereum DeFi protocols.

dlcBTC serves several functions:

* Allows Bitcoin holders to use their BTC as collateral on Ethereum-based DeFi platforms such as AAVE and Curve.
* Facilitates Bitcoin’s participation in Ethereum’s DeFi ecosystem, enhancing overall market liquidity.
* Ensures that Bitcoin can be used in DeFi without the risks associated with centralized custody.

### How Does dlcBTC Work?

Users lock their Bitcoin into a DLC using DLC.Link's self-wrapped bridge technology. This action mints dlcBTC tokens equivalent to the locked BTC amount. Each DLC functions as a secure lockbox, governed by a contract on the Bitcoin blockchain that includes a pre-signed agreement between the user and the protocol. Users hold one key to the multisig UTXO, while the second key is distributed among attestor nodes, ensuring that the DLC can only be liquidated back to the original user, thus preventing theft or loss.

### Who Are the Founders of dlcBTC?

DLC.Link, the entity behind dlcBTC, was co-founded by a team based in Brooklyn, NYC, with expertise in blockchain technology and cybersecurity. The founders aimed to address the vulnerabilities associated with custodial and bridge solutions, which have historically led to significant asset losses.

### Attestor Layer of dlcBTC

The attestor layer comprises seven trusted node operators who support the bridge by facilitating reliable cross-chain communication. This layer is critical for maintaining the security and integrity of the bridge without controlling users’ keys.

### How Many dlcBTC Coins Are There in Circulation?

The supply of dlcBTC tokens is directly tied to the quantity of BTC locked using DLC.Link’s bridge technology. As Bitcoin is locked into DLCs, dlcBTC tokens are minted on a 1:1 basis, ensuring that each token is always backed by a corresponding amount of locked Bitcoin.

### How Is the dlcBTC Network Secured?

The dlcBTC network is secured through the robust security features of both the Bitcoin and Ethereum blockchains, complemented by the private, secure transactions enabled by Discreet Log Contracts. The decentralized distribution of keys among attestor nodes further enhances security by protecting against unauthorized access and eliminating single points of failure.

### Where Can You Buy dlcBTC (DLCBTC)?

dlcBTC tokens can be obtained by locking BTC into the DLC.Link bridge. These tokens are also available for trading on various cryptocurrency exchanges that support Ethereum-based assets. dlcBTC provides a secure and user-friendly way for Bitcoin holders to integrate into Ethereum's DeFi ecosystem without compromising the ownership of their assets.
