When you send Bitcoin to someone, you're not actually handing over a file—you're signing a cryptographic statement. Bitpie Wallet handles this by managing your private keys locally on your device. These keys never touch their servers. Every transaction you make is signed right where you hold your phone, ensuring that your assets remain yours alone. This is the core of cryptography in action: ownership through math, not trust.

The wallet doesn't just store one type of crypto. It generates unique addresses for different blockchains using hierarchical deterministic (HD) technology. From a single seed phrase, it creates an infinite tree of key pairs. This means you can have Bitcoin, Ethereum, and TRX addresses all backed by the same recovery phrase, but each transaction remains isolated and private on its respective network.

Beyond transfers, Bitpie interacts with decentralized applications through secure transaction signing. When you swap tokens or interact with a DeFi protocol, the wallet constructs the raw transaction data, you review it, and your device signs it. Cryptography ensures that this data cannot be tampered with after signing. It's the silent guard that lets you move value across the globe without intermediaries.
