<h2 class="heading-node">About Superteam Ukraine</h2>We're Superteam Ukraine, and we're all about empowering our community to build awesome stuff on Solana. We help talented folks in Ukraine connect, learn, and contribute to the global Solana ecosystem.<h2 class="heading-node">Mission</h2>Create an open-source, unified SDK for React Native that enables Solana dApps to connect to and interact with multiple hardware wallets via a single, consistent API.<h2 class="heading-node">Scope Detail</h2><ul class="list-node"><li>Supported Hardware Wallets: The SDK must support Ledger, Trezor, Keystone, and SafePal. Support for Unruggable, Tangem, and Solflare Shield will be considered a bonus.</li><li>Core Functionality:<ul class="list-node"><li>Device Discovery &amp; Connection: Detect and connect to hardware wallets using their supported transport methods (Bluetooth, NFC, USB, QR code).</li><li>Account Derivation: Retrieve Solana public keys/addresses from the device using standard derivation paths.</li><li>Transaction Signing: Pass a Solana <code class="inline" spellcheck="false">Transaction</code> or <code class="inline" spellcheck="false">VersionedTransaction</code> and receive a signed transaction.</li><li>Message Signing: Sign arbitrary messages (byte arrays) for use cases like Sign-In With Solana (SIWS).</li><li>Multi-Account Support: Allow selecting different derivation indices.</li></ul></li><li>Architecture Guidelines:<ul class="list-node"><li>Monorepo structure.</li><li>Adapter pattern: Each hardware wallet should be implemented as a pluggable adapter.</li><li>Written entirely in TypeScript with full type definitions.</li><li>Minimal dependencies, relying on well-maintained libraries.</li></ul></li></ul><h2 class="heading-node">Submission Requirements</h2><ul class="list-node"><li>The SDK must be built in a public GitHub repository.</li><li>Include a comprehensive <code class="inline" spellcheck="false">README</code> file covering:<ul class="list-node"><li>Architecture overview with diagrams.</li><li>Getting started guide for React Native.</li><li>API reference for all public methods.</li><li>Per-wallet setup notes (e.g., "Ledger requires the Solana app to be open").</li><li>Troubleshooting/FAQ section.</li></ul></li><li>Published npm packages (or ready-to-publish).</li><li>Example applications:<ul class="list-node"><li>React Native demo app showcasing main flows.</li><li>Example scripts (CLI or Node.js) for programmatic usage and testing.</li></ul></li><li>The GitHub repo must have an MIT or Apache-2.0 license.</li><li>Submit your GitHub repository link on this listing.</li></ul><h2 class="heading-node">Judging Criteria</h2><ul class="list-node"><li>Functionality &amp; Correctness (30%): Does the SDK work end-to-end for supported wallets, including connection, account derivation, transaction signing, and message signing?</li><li>Code Quality &amp; Architecture (25%): Is the code clean, well-typed, modular, and extensible? Is the adapter pattern effectively implemented?</li><li>Wallet Coverage (15%): How many of the listed hardware wallets are supported?</li><li>Developer Experience (15%): Are React Native hooks intuitive? Is the README clear and thorough? Are error messages helpful?</li><li>Demo &amp; Examples (10%): Do the example apps clearly demonstrate the SDK's capabilities?</li><li>Tests (5%): Is there meaningful test coverage?</li></ul><h2 class="heading-node">Reward Structure</h2><ul class="list-node"><li>1st Place: 800 USDG</li><li>2nd Place: 200 USDG</li></ul>
