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 the popular Trust Wallet, and some 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.

For comprehensive documentation, see developer.trustwallet.com.

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

For build instructions, see developer.trustwallet.com/wallet-core/building.

If you want to use wallet core in your project follow these instructions.

Android releases are hosted on GitHub packages, you need to add GitHub access token to install it. Please check out this installation guide or build.gradle from our android sample

Don't forget replacing the version in the code with latest:

We currently support Swift Package Manager and CocoaPods (will discontinue in the future).

Download latest Package.swift from GitHub Releases and put it in a local WalletCore folder.

Add this line to the dependencies parameter in your Package.swift:

.package(name: "WalletCore", path: "../WalletCore"),

Or add remote url + master branch, it points to recent (not always latest) binary release.

.package(name: "WalletCore", url: "https://github.com/trustwallet/wallet-core", .branchItem("master")),

Then add libraries to target's dependencies:

.product(name: "WalletCore", package: "WalletCore"),
.product(name: "SwiftProtobuf", package: "WalletCore"),

Add this line to your Podfile and run pod install:

pod 'TrustWalletCore'

npm install @trustwallet/wallet-core

Please check out the Go integration sample.

Please check out the Kotlin Multiplatform sample
