Cardano Mainnet Unveils Historic First-Ever Direct BTC Transfer Through BitcoinOs!

Jakarta, Pintu News – On May 4, 2025, a major step was taken in the blockchain world with the successful transfer of Bitcoin to the Cardano network using BitcoinOS technology without the need for bridges or guards.

This innovation marks a new era in secure and efficient inter-chain transactions.

Introduction to BitcoinOS Technology

BitcoinOS has developed the BitSNARK protocol and xBTC token standard that allows direct transfer of Bitcoin (BTC) to the Cardano (ADA) network without intermediaries.

The process begins by locking up Bitcoin (BTC) on the first layer of Bitcoin, then converting it into xBTC tokens. These tokens are then sent directly from the BitcoinOS wallet to Sundial’s Cardano wallet.

This newly introduced technology eliminates the need for a third-party custodian or bridge, using zero-knowledge cryptography to ensure secure and verifiable transactions.

The Sundial protocol, a Layer 2 hybrid solution for Bitcoin (BTC) and Cardano (ADA), was used to receive xBTC tokens on Cardano. The tokens were then moved to a wallet owned by ADA Handle, demonstrating seamless integration within the Cardano ecosystem.

This process ends with the burning of xBTC and the liberation of the original Bitcoin (BTC) back onto the Bitcoin blockchain, completing the full journey without the traditional bridge mechanism.

Implications for Cardano and the Broader Crypto Ecosystem

This development marks a major advancement in Cardano’s capabilities, placing it as an important player in decentralized finance .

By enabling direct Bitcoin (BTC) transactions, Cardano opens the door for new DeFi applications and increases utility for Bitcoin holders. Charles Hoskinson, founder of Cardano, emphasized the importance of this integration, stating that it is a significant step towards a more connected blockchain ecosystem.

In addition, with a strategic focus on interoperability and security, Cardano plans to further integrate Bitcoin (BTC) into its ecosystem, including potential support for Bitcoin staking and DeFi applications.

Despite the technological breakthrough, Cardano’s native token, ADA, experienced a slight price drop. As of 2025, ADA is trading around $0.6585, showing a decrease of 2.86% in the last 24 hours and 5.79% in the last week.

Charles Hoskinson recently discussed that the blockchain industry is entering a new phase of development that should focus on scalable solutions to real-world problems.

By eliminating the need for bridges and guards, BitcoinOS addresses security concerns that have caused more than $2 billion in losses since 2022.

xBTC introduces a programmable Bitcoin format while remaining non-custodial, operating similarly to wETH on Ethereum , but within the Bitcoin framework.

Overall, these innovations not only improve security and efficiency in inter-chain transactions but also open up new opportunities in the DeFi ecosystem.

By combining enhanced security and ease of integration, Cardano and BitcoinOS set a new standard in blockchain operations.
