Trust Wallet Core is a cross-platform library that implements low-level cryptographic wallet functionality for all supported blockchains. Most of the code is C++ with a set of strict exported C interfaces. The library provides idiomatic interfaces for all supported languages (currently Swift for iOS and Java for Android).

Supported Blockchains

We support Bitcoin, Ethereum, Binance Chain and 50+ blockchains, you can see the full list here.
