Multisig Wallet

An Android application that enables advanced Bitcoin asset management. It supports multisignature transactions in an M-of-N scheme using the BIP-48 and BIP-67 standards, manual selection of unspent transaction outputs (coin control), and integration with the Trezor hardware wallet via the Trezor Connect protocol. The PSBT format defined by BIP-174 is used for distributing partially signed transactions among cosigners. The backend is implemented as a set of microservices in Kotlin with the Ktor framework, while the frontend is a native Android application built with Jetpack Compose.
