Crypto wallet development
Non-custodial wallets for your own chain or for existing networks, with the keys staying on the user device. The build covers BIP-39 seed phrase generation and recovery, encrypted on-device key storage, transaction signing, broadcasting and history, an address book, and support for multiple networks and tokens. One wallet ships across three platforms: web, Electron desktop and native Android in Kotlin with Jetpack Compose. Delivered: a wallet for an in-house Layer-1 across web, desktop and Android, and a web wallet with a block explorer for a C++ coin. Stack: TypeScript, React, Electron, Kotlin, Rust, WebAssembly. From 3,500 USD, from 4 weeks.
