Macadamia released version 0.4.0 on September 23, 2025, with an iMessage extension that enables users to send ecash, a Bitcoin-backed digital currency, in iMessage conversations. The update will substitute the old-fashioned, complicated BTC addresses with a smooth and user-friendly interface, making the crypto transactions accessible to anyone.

The new extension linked to cryptocurrency transactions, and users are now able to send BTC in a manner that is reminiscent of messaging. The launch is a continuation of an increasing trend in which technology platforms such as Apple are adding cryptocurrency functionalities in order to hasten their uptake.

Lightning Network and Cashu Protocol: How It Works.

Macadamia Crypto Wallet uses the Cashu protocol and the Lightning Network of Bitcoin to make instant and private payments. A second-layer solution, the Lightning Network, can process up to 1 million transactions each second off-chain, which is more than seven times more than the base layer of Bitcoin, which supports 7 transactions per second. Micro-transactions are also cheap, fast, and secure because off-chain processing incurs up to 90% less transaction fees.

The wallet can be funded with BTC using a Lightning invoice by connecting the Macadamia to a Cashu mint. When filled up, it is as easy to send Bitcoin as it is to choose a contact in iMessage, type an amount, add a memo, and select an emoji banner to give it a personal touch.

Step-by-Step guide to send Bitcoin through Apple iMessage

• Download Macadamia: Open the application through TestFlight or Apple App Store (iOS 17.5 or higher).

• Connect to a Cashu Mint: You have to choose a mint in the "Mints" section and enter the URL in the wallet.

• Top Up Wallet: Add money with a Lightning Network invoice in a different Bitcoin wallet.

• Transfer BTC through iMessage: Tap a chat, select the Macadamia extension, type in the amount, memo, and optional emoji banner, and tap Send.

• Confirm Transaction: The recipient is provided with BTC in the form of an ecash token, which is visible with the selected banner and memo.

Potential Adoption and Benefits.

With the integration, the iPhone base of $1.56 billion and the number of Apple Pay accounts 624 million in 2025 will increase the reach of BTC beyond the 12-28% global adult cryptocurrency adoption rate. Its easy-to-use interface, along with the privacy and free of charge Lightning payments, makes Macadamia a viable alternative to the conventional payment applications.

Also, new regulatory measures in the U.S. have enabled Apple to relax crypto app restrictions, allowing such features as in-app digital asset transfers without added fees, further encouraging mainstream adoption.

Developer Insights and Community Response.

Cryptocurrency users have embraced the feature. There are tutorials, such as the one by Erik, that instruct a user on how to top up wallets and send ecash without any hitch. Macadamia is a privacy-focused, security-focused, and accessibility-focused wallet developed by Cypherbase UG and focused on both new and experienced users.

Conclusion

This update will make crypto transactions easier by integrating the efficiency of the Lightning Network and the vast user base of Apple, which will encourage more people to adopt and use digital currencies in practice.
