Cardano continued to advance his references as a place of Bitcoin Defi (BTCFI), facilitating an ordinals to its principal.
The chain transaction between Bitcoin and Cardano was facilitated by BitVMX, an interoperability protocol built using the Bitvm programming language.
The transaction was unveiled by entrance | Exit (IO), the creator of layer 1 Cardano, during the Bitcoin 2025 conference in Las Vegas on Tuesday.
The bridge represents an “overview of what is to come,” said IO in an announcement by email. Its ultimate objective is a complete integration between Bitcoin and Cardano, providing DEFI services for BTC users and unlocking huge quantities of liquidity from the value stored in Bitcoin.
To this end, IO has developed the “cardinal” protocol, a portmanteau de Cardano and ordinals, which exploits Bitvmx to attribute native Bitcoin assets to addresses on Cardano.
The ordinal protocol was introduced at the beginning of 2023, allowing the registration of data on individual Satoshis (the smallest name of the BTC, equivalent to a 100 millionth of Bitcoin), which makes them unique and traceable. Indeed, this created a bitcoin equivalent of non -failed tokens (NFT).
