frBTC Overview

Interoperable Wrapped BTC of Bitcoin L1

frBTC is the Bitcoin DeFi-compatible asset pegged 1:1 to BTC and interoperable across every DeFi ecosystem on Bitcoin L1.

This is achieved through a trust-minimized process that locks BTC on the Bitcoin mainnet (Layer-1) and atomically mints a corresponding amount of frBTC for the user.

SUBFROST launched on Bitcoin mainnet in Q4 2025. Alkanes (October) & BRC2.0 (December).

How can I use frBTC?

FOR THE FIRST TIME

Users can perform a single signing process to enter advanced DeFi apps on Bitcoin L1 with native BTC, completely abstracting-away the need to wrap their BTC first.

The example below illustrates a user swapping native BTC to a USD stablecoin (or other token), atomically, in a decentralized, permissionless manner.

frBTC is live on Alkanes and BRC2.0, and we have already begun development to implement it on Arch & MIDL.
