DLC-Based Self-Custody Wrapping for Bitcoin DeFi

Article OKX Learn
Read the original

Summary

The document describes DLC.Link’s approach to making Bitcoin usable in DeFi through dlcBTC, a wrapped asset that the project says is created without depositing Bitcoin with a custodian or moving it to another blockchain. A depositor locks Bitcoin collateral in a Discreet Log Contract (DLC), whose payout is restricted to that depositor. The stated design goal is to support self-custody and reduce exposure to theft and censorship associated with custodial wrapped assets.

For cross-chain use, the document describes Ethereum validators operated by a network of attestors, including institutional node operators. It says DLCs are supported by Bitcoin’s Taproot upgrade and presents them as an alternative to systems that rely on a separate bridge or sidechain. The source is an investment announcement, so its descriptions of security and resistance to theft are project claims, not independently demonstrated findings. It provides no implementation details, audits, performance data, or comparative risk analysis.

Key ideas

  • DLC.Link describes dlcBTC as a Bitcoin-backed asset intended for use in DeFi while Bitcoin remains in depositor-controlled custody.
  • The depositor locks collateral in a Discreet Log Contract whose payout is designed to return funds only to that depositor.
  • The protocol uses Ethereum validator operators as attestors for cross-chain activity.
  • The announcement presents DLCs as a way to connect Bitcoin with DeFi without a separate bridge or sidechain.
  • The document is an investment announcement and supplies no independent security or performance evidence.
