# Telegram Desktop applies it on top of the engine and uses its API

Patch:         wallet-engine.patch

# Rust is a bundled dependency on Fedora: use the system toolchain directly.

%description
Wallet Engine is a Rust library for TON wallet applications: it creates and
imports wallets, parses and formats TON addresses, signs and submits
transfers, and connects decentralized applications over TON Connect. It is
used by Telegram Desktop 7.3 and newer.

%description devel
Wallet Engine is a Rust library for TON wallet applications: it creates and
imports wallets, parses and formats TON addresses, signs and submits
transfers, and connects decentralized applications over TON Connect. It is
used by Telegram Desktop 7.3 and newer.

This package contains the link library and the C++ binding generated by
UniFFI (a header and a source file which the application compiles and links
itself).
