Wallet Core

Introduction

Trust Wallet Core is an open-source, cross-platform, mobile-focused library implementing low-level cryptographic wallet functionality for a high number of blockchains. It is a core part of Trust Wallet and several other projects.

Most of the code is C++ with a set of strict C interfaces, and idiomatic interfaces for supported languages: Swift for iOS and Java/Kotlin for Android. Additional bindings are available for Rust, Kotlin Multiplatform, WebAssembly, Go, and NPM (beta).

Wallet Core supports more than 130 blockchains: Bitcoin, Ethereum, BNB, Cosmos, Solana, and most major blockchain platforms. The full list is in the registry.
