What technologies do crypto wallet developers use?

Crypto wallet developers use a combination of blockchain frameworks, programming languages, and security protocols to build secure and user-friendly wallets. Blockchain platforms like Ethereum, Binance Smart Chain, and Solana are commonly integrated to enable multi-currency support.Programming languages such as Solidity, Python, JavaScript, and C++ are widely used depending on the blockchain's requirements. Developers also rely on frameworks like Web3.js and ethers.js for blockchain interaction.For mobile wallets, technologies like React Native or Flutter allow cross-platform compatibility, while back-end technologies such as Node.js and MongoDB handle server operations and data storage.Security protocols, including AES encryption and Transport Layer Security (TLS), are used to protect user data and transactions. Developers also integrate APIs like Coinbase or blockchain explorers for additional features.These technologies, combined with expertise, ensure a high-performance and secure crypto wallet.
