How to Develop Cryptocurrency Wallets with Swift for iOS?

In this article, we’ll explore how to develop cryptocurrency wallets using Swift for iOS

Cryptocurrency wallets have become an integral part of the digital landscape, allowing users to securely store, send, and receive cryptocurrencies like Bitcoin, Ethereum, and others. With the increasing popularity of cryptocurrencies, the demand for reliable and user-friendly wallet applications has grown significantly. In this article, we’ll explore how to develop cryptocurrency wallets using Swift for iOS, Apple’s powerful and intuitive programming language.

Understanding Cryptocurrency Wallets:

Before delving into the development process, it’s crucial to understand the basic functionality of cryptocurrency wallets. A cryptocurrency wallet is a software application that securely stores public and private keys, enabling users to interact with the blockchain network. The public key serves as the wallet address, allowing users to receive funds, while the private key is used to sign transactions and access funds stored in the wallet.

Setting Up the Development Environment:

To develop cryptocurrency wallets with Swift for iOS, you’ll need access to Apple’s Xcode development environment, which includes the Swift programming language and essential tools for iOS app development. Xcode can be downloaded from the Mac App Store and is available free of charge.

Choosing the Wallet Architecture:

When developing a cryptocurrency wallet, it’s essential to consider the wallet architecture. There are primarily two types of cryptocurrency wallets:

Hot Wallets: Hot wallets are connected to the internet and allow for easy access to funds, making them suitable for daily transactions and trading. However, they may be more vulnerable to security breaches.

Cold Wallets: Cold wallets are offline storage solutions that provide enhanced security by keeping private keys offline. They are typically used for long-term storage of large cryptocurrency holdings.

Implementing Key Features:

1. Wallet Creation and Restoration:

Enable users to create new cryptocurrency wallets with a secure backup mechanism.

Implement wallet restoration functionality using mnemonic phrases or seed words.

2. Secure Key Management:

Utilize cryptographic techniques to securely manage public and private keys.

Implement key derivation functions (KDFs) to derive keys from mnemonic phrases or seed words.

3. Address Generation and QR Code Support:

Generate unique wallet addresses for receiving cryptocurrencies.

Implement QR code scanning functionality to simplify the process of sending and receiving funds.

4. Transaction Handling:

Facilitate seamless transaction processing, including sending and receiving cryptocurrencies.

Implement transaction signing using private keys to authorize outgoing transactions.

5. Multi-Currency Support:

Provide support for multiple cryptocurrencies within the same wallet application.

Implement APIs or libraries to interact with various blockchain networks and protocols.

6. Security Measures:

Implement robust security measures, such as biometric authentication (Touch ID, Face ID) and PIN/password protection.

Encrypt sensitive data stored within the wallet application to prevent unauthorized access.

Leveraging External Libraries and APIs:

To streamline the development process and enhance functionality, developers can leverage existing libraries and APIs designed specifically for cryptocurrency wallet development. Some popular libraries and APIs include:

BitcoinKit: A Swift library for working with Bitcoin protocol.
Web3.swift: A Swift library for interacting with Ethereum blockchain.
Coinbase API: Provides access to Coinbase’s cryptocurrency exchange and wallet services.
Blockchain.com API: Offers various APIs for creating and managing cryptocurrency wallets.

Testing and Deployment:

Once the wallet application is developed, thorough testing is essential to ensure functionality, security, and user experience. Conduct both manual and automated testing to identify and address any bugs or vulnerabilities.

After successful testing, deploy the cryptocurrency wallet application to the Apple App Store following Apple’s guidelines and submission process. Regularly update the application to incorporate new features, security patches, and improvements based on user feedback and industry developments.

Conclusion:

Developing cryptocurrency wallets with Swift for iOS presents a rewarding yet challenging endeavor. By understanding the fundamental principles of cryptocurrency wallets, leveraging Swift’s capabilities, and implementing key features and security measures, developers can create robust and user-friendly wallet applications that cater to the evolving needs of cryptocurrency users on the iOS platform. As the cryptocurrency landscape continues to evolve, the demand for innovative wallet solutions will undoubtedly grow, making Swift an invaluable tool for developers looking to enter this dynamic and rapidly expanding field.

1 Artificial Intelligence (AI) Stock With More Potential Than Any Cryptocurrency | The Motley Fool

Press Room

Crypto is stumbling while AI is advancing.

We’re in one of those times when market players are shunning crypto investments. Factors such as persistent inflation, a declining likelihood of interest rate cuts (typically a major catalyst for crypto price pops), and outflows from once-hotly popular crypto exchange-traded funds (ETFs) have put the hurt on even the most prominent digital coins and tokens.

Given that, it’s worthwhile to consider another high-potential technology — artificial intelligence (AI). Despite huge growth opportunities ahead, AI has also taken it on the chin lately as well. It still has a bright future, and I believe investors can still hop on this train with a company that’s not a pure play, but one deeply — albeit not exclusively — involved in the technology.

Read on to see what AI giant I believe can outpace even the most popular cryptocurrencies.

Image source: Alphabet.

Alphabet is advancing AI

That company is none other than Google owner Alphabet (GOOG +0.68%)(GOOGL +0.68%). Although it’s still known, with some justification, as a search engine operator, the company has been neck-deep in AI for years. It’s developed both hardware and the large language models (LLMs) powered by it, and it clearly aims to be a top name in this technology.

I have no doubt it can succeed. Google’s AI component Gemini is now fused into the company’s search and many other features (like Google Mail). This makes it a convenient option for web searchers querying for more than basic information on a subject. Its functionalities are also integrated into offerings like Google Docs, where users can harness AI to help with their writing. The Gemini platform itself is a hot item, with a monthly active user count now topping 750 million.

On the hardware front, Alphabet is not only actively developing and deploying Tensor Processing Units (TPUs) — chips designed to power AI functionality — it invented them. Originally designed to bolster the company’s AI capabilities, the processors are now being sold to external customers, opening another revenue stream.

AI is a growth catalyst for Alphabet

Alphabet doesn’t break out the revenue it derives from AI hardware and services, so we can’t put a precise number on how much the technology is bringing in for the company.

Still, it’s clearly foundational these days — the phrase “AI” was mentioned 94 times during management’s fourth-quarter and full-year 2025 earnings conference call. And the tech giant stated in the accompanying earnings release that “We’re seeing our AI investments and infrastructure drive revenue and growth across the board.”

Alphabet’s two main revenue buckets, Google Services and Google Cloud — both of which feature AI-enhanced products — have seen robust increases. The former’s revenue grew 14% year over year during the quarter to almost $96 billion, while the latter’s skyrocketed 48% to just under $18 billion.

The numbers don’t lie. Even if the economy slows or inflation remains stubborn, demand for Alphabet’s impressively large suite of AI products and services will remain strong. I’d feel much more confident parking my money in this AI stock than gambling it on a wobbly cryptocurrency.

Florida man arrested in 8M cryptocurrency Ponzi scheme: DOJ

APOPKA, Fla. – A 34-year-old Florida man, who served as the president and CEO of an alleged cryptocurrency investment firm, has been accused of running a $328 million Ponzi scheme, according to the U.S. Department of Justice.

Christopher Alexander Delgado, of Apopka, Florida, was arrested on federal charges of wire fraud and money laundering, the DOJ announced on Tuesday.

The backstory:

According to the DOJ, Delgado was the CEO and founder of Goliath Ventures, formerly known as Gen-Z Venture Firm.

The DOJ alleges that Delgado convinced people to invest a total of $328 million with his firm between January 2023 & January 2026 under the assumption that it would be invested in cryptocurrency “liquidity pools” – and would promise monthly returns.

The DOJ alleges that the money was instead used to pay returns and principals to previous investors, as well as to pay for lavish business gatherings, holiday parties, and to buy four multi-million-dollar homes (varying in cost between 1.15M and $8.5M).

“Victims were induced to give money to Goliath through personal referrals, professional marketing materials, luxury events, charitable sponsorships, and some monthly payments of purported returns, all of which were designed to establish Goliath’s bona fides with investors,” the DOJ said in a news release.

If convicted, Delgado faces up to 30 years in federal prison, the DOJ said.

According to the complaint, Delgado bought four homes:

$3.2 million home in Winter Park in July 2025
$1.15 million home in Kissimee in December 2024
$8.5 million home in Windermere in September 2025
$1.65 million home in Sanford in August 2024

Victim: Lost $720,000

According to the complaint, one unnamed investor reportedly lost $720,000 in Delgado’s alleged scheme. A second investor was reportedly able to get his money back, though he had to directly contact Delgado to ensure he did. The amount of money returned in the second example was not disclosed.

What you can do:

The DOJ said anyone who thinks that they could have been a victim of Delgado’s business to email Goliathvictims@ci.irs.gov. Or to visit this website.
