Trust Wallet Core is a cross-platform, mobile-focused cryptographic wallet library that implements low-level blockchain functionality for over 130 blockchains.
The library solves the problem of building secure wallet infrastructure across multiple blockchain networks and platforms. It provides a C++ foundation with strict C interfaces and idiomatic bindings for Swift on iOS and Java/Kotlin on Android, allowing developers to integrate wallet functionality without reimplementing complex cryptographic operations. The approach centralizes blockchain-specific logic in a single, audited codebase that can be reused across different applications and platforms.
Developers should choose this tool if they are building mobile wallet applications or services that need to support multiple blockchains. It suits projects requiring production-grade security, as the library includes audit reports and is battle-tested through use in Trust Wallet and other established cryptocurrency projects. The tool provides native language bindings for iOS and Android development, with beta support for NPM, Go, and Kotlin Multiplatform, making it accessible across different development stacks. Community-maintained bindings exist for additional platforms like Flutter and Windows, though these are not officially endorsed.
The project maintains active development with regular updates to support new blockchains and platforms. The codebase receives security audits with reports publicly available. Integration documentation is comprehensive and kept current, with build instructions and platform-specific guides available through the developer portal. The project accepts community contributions and tracks external projects that extend its functionality to additional platforms and languages.
