By Neon Wallet: Unlocking Stellar
This grant will fund the deep integration of Stellar into our proven infrastructure, positioning Neon Wallet as a premier gateway for cross-ecosystem activity involving Stellar:
We will integrate Stellar into our core Unified Asset Hub, allowing users to manage their Stellar portfolio alongside their other assets from a single, seamless interface.
Soroban Account Abstraction & Passkey Onboarding: This is our flagship feature. We will build a revolutionary, "wallet-less" user experience by:
Seedless Security: Users will create a secure, non-custodial wallet using their device's Passkey (Face ID, biometrics) instead of a complex seed phrase.
Gas-less Onboarding: Leveraging Sponsored Transactions, users can create their first wallet without needing to purchase XLM. A backend "sponsor" will cover the initial network fees.
Smart Wallet Architecture: We will develop and deploy a Soroban WalletFactory contract that creates a personal, upgradeable SmartWallet contract for each new Passkey user.
Social Recovery: The SmartWallet will have Social Recovery logic built-in, allowing users to regain access via trusted guardians if they lose their primary device, solving the greatest risk of seedless wallets.
Cross-Chain Liquidity Bridge: We will leverage our existing swap integrations to create a direct liquidity pipeline, enabling users to seamlessly exchange assets between Stellar, EVM chains, and Neo from the comfort of their wallet.
Integration with Stellar Ramps: We will provide a frictionless fiat gateway by embedding Mercuryo directly into the UI, cementing our position as your one-stop shop for crypto by allowing users to easily buy and sell Stellar assets with local fiat currencies, which drastically lowers onboarding barriers and drives immediate liquidity into the ecosystem.
Native DeFi Yield via Blend v2: We will unlock seamless, in-app earning opportunities by integrating Stellar's Blend v2 protocol, empowering users to simply supply liquidity and earn interest on their assets natively, which democratizes DeFi access and actively fuels Soroban’s Total Value Locked (TVL).
Fortified Security & Interoperability: We will extend our full security suite to Stellar users, including Ledger Hardware Wallet support, a single BIP39 seed phrase (for traditional accounts), and robust WalletConnect support.

Neon Wallet is a mature, trusted wallet with over 1,000,000 downloads and a proven history in the market since 2017. As the primary wallets in the Neo ecosystem, our platform has reliably processed billions of dollars in transaction volume, demonstrating our central role and long-term stability in that community.
This trust is built on proven technical capabilities, including live support for Neo and major EVM networks, alongside essential in-wallet services for cross-chain swaps, fiat on/off-ramps, and dApp connectivity.
This technical reliability was recently demonstrated in a complex migration for our Neo users, which seamlessly moved millions of dollars in assets, underscoring our ability to handle critical, large-scale operations.
