Purpose of SUBFROST

Bitcoin DeFi is one of the most promising spaces in finance. However, native BTC is not compatible with complex applications built on Bitcoin L1 ecosystems, like AMMs, borrow/lends and zK mixers.

SUBFROST exists to issue two Defi-compatible BTC synthetics, crucial to a competitive DeFi ecosystem on Bitcoin:

  1. frBTC: the first and only synthetic asset pegged 1:1 to BTC on Bitcoin, enabling users to leverage their BTC across any application without ever leaving the Bitcoin blockchain.
  2. dxBTC: the yield-bearing variant of BTC, enabling users to maintain full exposure to BTC while earning a yield in the simplest and most secure way possible.

What is SUBFROST?​

SUBFROST is a decentralized custodian that enables a trustless DeFi ecosystem on Bitcoin L1.

It operates as a Layer-0, designed to issue BTC synthetic assets directly onto Bitcoin via metaprotocol execution layers like Alkanes, BRC 2.0 and OP_NET.

Sound boring? Well, without a BTC synthetic like frBTC, there will be a lack of adoption in Bitcoin DeFi and a continued reliance on trust-dependent, cross-chain options like wrapped BTC on Ethereum.
