horizontalsystems/unstoppable-wallet-android — A powerful non-custodial multi-wallet for Bitcoin, Ethereum, Binance Smart Chain, Avalanche, Solana…

Description and use

**Brief Summary**
Unstoppable Wallet Android is a Kotlin‑based, non‑custodial multi‑wallet that supports Bitcoin, Ethereum, BSC, Avalanche, Solana and many other chains, offering on‑chain NFT storage, decentralized exchange, analytics and strong privacy controls. With 1.2 k ⭐ and active development, it serves as a ready‑to‑use reference implementation for building or inspecting Web3, DeFi and NFT workflows on Android.

**Value**

• **Open implementation**: All core wallet, DEX and analytics logic is exposed in clean Kotlin code, making it easy to study, extend, or reuse in custom projects.
• **Multi‑chain & NFT support**: One codebase handles UTXO‑ and account‑based chains plus NFT standards, reducing the need to stitch together separate SDKs.
• **Enterprise‑grade features**: Built‑in privacy settings, on‑chain order‑book DEX and institutional‑level market analytics give developers a production‑ready feature set without licensing expensive proprietary libraries.

**Practical Adoption Path**

1. **Clone & build** the repository (Gradle + Android Studio) to verify the baseline wallet runs on a test device.
2. **Identify integration points** (e.g., WalletApi, DexService, AnalyticsProvider) and replace or extend them with your own business logic or UI.
3. **Swap network configurations** via the provided NetworkConfig files to point to testnets or private nodes for prototyping.
4. **Add custom modules** (e.g., a new DeFi protocol) by implementing the existing BlockchainAdapter interfaces, then run the built‑in integration tests.
5. **Package & deploy** the modified app as a standard Android APK/AAB for internal pilots or public release.

**Production Readiness**

• **Activity & community**: Recent commits (last update 2026‑06‑22), 1,202 ⭐ and 482 forks indicate a healthy, engaged community.
• **Code quality**: Kotlin codebase, clear module separation, and comprehensive unit/instrumentation tests suggest a stable foundation.
• **Ecosystem fit**: The wallet already integrates major chain SDKs, on‑chain DEX contracts and analytics pipelines, so most production requirements are covered out‑of‑the‑box.
• **Risks**: Licensing terms, formal security audits and long‑term maintainer commitment still need verification before a mission‑critical rollout.

Overall, the project is a strong OSS candidate for pilots or full production deployments of Android‑based Web3 wallets and DeFi services.

Problem

horizontalsystems/unstoppable-wallet-android helps prototype or inspect blockchain workflows with open implementation details.

Outcome

High for an OSS candidate: recent activity, adoption, and ecosystem signals are strong enough for a serious pilot.

Workflow

• build Web3 workflows
• inspect blockchain integrations
• prototype wallet or DeFi features

Evidence
