Cardano’s research and engineering arm, Input Output Global (IOG), has unveiled “Cardinal,” the first protocol that allows native Bitcoin unspent transaction outputs (UTXOs) — including Ordinals — to circulate inside Cardano-based decentralized-finance markets without custodians or federations.

The disclosure came late Monday when IOG chief technology officer Romain Pellerin published a nine-part thread on X describing Cardinal as “a new primitive for Bitcoin,” adding that his team has “made history with the first cross-chain Ordinal wrap.” He summarized the design in a single sentence: “Bitcoin stays locked under MuSig2; the wrapped UTXO is minted cross-chain; it is redeemable at any time via fraud-proofed peg-out — no rehypothecation, no compromise.”
