The Bitcoin-Cardano Bridge is Here: What it Means for DeFi

Cardano has launched Cardinal, a pivotal protocol aiming to bridge Bitcoin's vast liquidity with Cardano's decentralized finance (DeFi) ecosystem.

This initiative, highlighted by Cardano founder Charles Hoskinson and IOG CTO Roman Pellerin, marks their most direct effort yet to integrate Bitcoin.

While already capable of wrapping and unwrapping Ordinals, Pellerin notes the protocol isn’t “production-ready” yet, with improvements planned for the 1.0 version.

Cardinal lets Bitcoin holders access DeFi services like lending and borrowing on Cardano without relying on centralized bridges.

It achieves this by securely “wrapping” Bitcoin’s UTXOs into tokens with a one-to-one peg, allowing full redeemability.

The protocol employs a trust-minimized model and MuSig2 for enhanced security, ensuring decentralization and safeguarding against chain reorganizations.

Furthermore, Cardinal integrates BitVMX, an off-chain computation system, for efficient and programmable interactions between the two blockchains. This move by Cardano promises to open up significant new opportunities for both Bitcoin and the broader DeFi landscape.
