Protocol Description


dlcBTC is a decentralized wrapped Bitcoin on Ethereum, enabling Bitcoin holders to participate in DeFi protocols while retaining full ownership of their assets. dlcBTC leverages Discreet Log Contracts (DLCs) for secure cross-chain transactions, ensuring trustless and decentralized asset management. Unlike other bridges, dlcBTC is theft-proof as funds can only return to the original depositor. dlcBTC is minted by a permissioned set of merchants managed by the DLC Foundation, ensuring self-custody and reducing central points of failure. dlcBTC operates as an oracle-free system where 1 BTC = 1 dlcBTC, and its contracts have minimal parameters, making it a fully automated and robust solution.


WBTC (Wrapped Bitcoin) is a tokenized version of Bitcoin (BTC) that runs on the Ethereum blockchain. WBTC is backed 1:1 with Bitcoin and is managed by a consortium of custodians and merchants. WBTC is held in centralized custody by BitGo, introducing counterparty risk. WBTC enables Bitcoin holders to use BTC in the Ethereum ecosystem and access decentralized finance (DeFi) applications.


Incentivizing the dlcBTC/WBTC pool is essential to provide deep liquidity for both dlcBTC and WBTC, promoting their usage within the DeFi ecosystem. This will enhance the trading experience for users, ensuring low slippage and high availability for both tokens. Additionally, it will support the broader adoption of decentralized Bitcoin solutions in DeFi, fostering a more robust and diverse ecosystem.

DLC.Link has committed to co-incentivizing the dlcBTC/WBTC pool to ensure its success and sustainability. This strategic collaboration aims to attract a significant amount of liquidity, thereby enhancing the pool’s depth and efficiency.



dlcBTC operates with a minimized governance framework, detailed in this forum post. The protocol’s contracts have minimal parameters and operate as an oracle-free system where 1 BTC = 1 dlcBTC. This soft peg is maintained through market makers such as Amber Group.


dlcBTC utilizes a Chainlink proof of reserve feed to ensure transparency and trust in the system. That feed can be seen here: Chainlink dlcBTC PoR feed on Arbitrum

Additionally, the Curve BD team has built a custom oracle combining two NG pools (e.g., dlcBTC-WBTC and tricrypto-crvUSD pools). Details here: Custom ngOracle contract

Centralization Vectors

dlcBTC protocol has no major centralization vectors. Depositors’ Bitcoin is secured in a Discreet Log Contract (DLC), a special type of pseudo-programmable multisig that is supported natively on Bitcoin L1. Mint and burn signals are relayed through DLC.Link’s Attestor network (powered by node operators including Hashkey Cloud, OKX and Everstake).

However, the attestors cannot receive funds. Attestors cannot maliciously divert or burn a depositors’ BTC collateral, and the collateral can only be released to the wallet address that provided it.

dlcBTC is not a Bitcoin L2. DLCs are secured by the full hashrate of the Bitcoin network and utilize Arbitrum validators.

Market History

dlcBTC is a new asset supported by our initial merchants: Amber Group, IMC, and soon others including HashKey OTC, Time Research, and Psalion. Amber Group has recently minted an initial $1 million worth of dlcBTC, with additional merchants set to contribute significantly.

Also, dlcBTC has passed the first of three proposals to list as collateral on Aave: TEMP CHECK Onboard dlcBTC to Aave v3.
