Introducing Knight Shield

We're building Knight Shield — the first independent privacy-first mobile wallet for the Midnight Network.

Why Another Wallet?​

Most crypto wallets treat privacy as an afterthought. They focus on multi-chain support, token swaps, and pretty dashboards. But the fundamental problem remains: blockchain transactions are public, and sophisticated adversaries can correlate them to real identities.

Knight Shield is different. We're building privacy features that actively defend users against on-chain surveillance.

The Three Ghosts​

Knight Shield introduces three privacy layers — the Ghost Features:

GhostCloak​

Every transaction routes through a TLS relay, creating a fresh session each time. Your network identity is decoupled from your on-chain activity. No address reuse, no IP correlation.

GhostTracking​

Random delays between 500ms and 8 seconds break timing correlation. Fee normalization shows the same flat fee for every transaction, defeating fee-based fingerprinting. Two simple mechanisms that neutralize the two most common analysis vectors.

GhostShard​

Your wallet seed is split into 5 shards using Shamir Secret Sharing. Any 3 reconstruct the wallet. Each shard goes to a different location — USB key, password manager, secure enclave, cloud, or a DID document. No single point of failure.

Built on Midnight​

We chose the Midnight Network for its protocol-native zero-knowledge proofs. Compact — Midnight's smart contract language — compiles directly to ZK circuits. Our 5 contracts (SessionBilling, FeePool, ShardRegistry, FeeReserve, FungibleToken) leverage this to keep all state transitions private by default.

What's in the Box​

Knight Shield is a TypeScript monorepo with 6 packages:

  • core — Wallet SDK with Ghost feature clients
  • contracts — 5 Compact smart contracts
  • native-bridges — iOS SecureEnclave + Android Keystore integration
  • relay-server — Node.js TLS proxy for GhostCloak
  • mobile — React Native app with 7 screens
  • docs — This documentation site

What's Next​

We're in active development on preprod. Here's what's coming:

  1. Contract deployment on Midnight preprod
  2. Relay server hardening and public endpoint
  3. Mobile TestFlight / Play Store beta
  4. WalletConnect v2 integration
  5. Mainnet launch when Midnight is ready
