V1.0.0+270 — Colosseum release candidate

The V1 build sent to TestFlight as the release candidate. Twelve days of post-+158 hardening rolled into one drop.

Highlights

• VoIP — iOS PushKit + CallKit Self-Managed audio session hardened, Android Telecom dual-Connection zombie killed, Galaxy lock-bypass + cold-launch ACCEPT recovery, long-idle Signal recovery.
• Reply quotes — WhatsApp-style. drift schema v10 with denormalized fields persisted across the local→server ID swap (the bug that previously dropped the quote on ACK).
• Wallet V2 Phase 2 — Tensor-fork on-chain marketplace + 50 % community-fee split (devnet deployed).
• On-device AI — LiteRT-LM Gemma 4 E2B with 8 GB RAM gate. Apple Translation API session cache for iOS Korean.
• i18n locale lock — English-locked at the OS level (CFBundleLocalizations / Android resourceConfigurations) so the CallKit banner stays consistent on Korean-locale devices.
• Security — External audit Round 1 closed (Vuln 1~6 + AI prompt injection + Safety Number, 2026-04-18). Refresh-token publish-before-subscribe race fixed with SETEX cache.

✨ Highlights

🔐 Pure Dart Signal Protocol

Direct Dart implementation of X3DH + Double Ratchet + Sender Key Hybrid (groups). No libsignal binary, no Platform
Channel. Three internal audits. Standalone library:
kennss/dart-signal-protocol.

🛍 On-Chain NFT Marketplace + 50% Community Fee

Tensor-fork Anchor program with a custom snowchat_vault PDA. When a verified Metaplex Collection's creator runs the
channel, 50% of every trade lands in the community fund — atomically, on-chain, no opt-out. Program source:
kennss/marketplace (branch feature/snowchat-community-fee-share).

💼 Multi-Wallet (Solana, non-custodial)

BIP-39 + SLIP-0010 with Phantom-compatible derivation (m/44'/501'/{account}'/0'). Multi-account, hide / unhide,
biometric gate. Keys live only in iOS Keychain / Android Keystore.

🆔 Sovereign Identity

SnowChat IDs are deterministic hashes of the wallet — no phone, no email, no Web2 PII. Recovery via BIP-39 mnemonic only.

📞 Voice Calls (VoIP)

WebRTC P2P, Sealed Sender signaling over Socket.IO. iOS CallKit + Android ConnectionService. Cloudflare Realtime TURN,
FCM Voice Push.

🤖 On-Device AI

Forked flutter_gemma running Gemma 4 E2B (llama.cpp on iOS, LiteRT-LM on Android). Apple Translation API for Korean, ML
Kit language detector, agentic Tool Use router. Zero server transmission — all inference runs on-device.

🛰 Network

This release runs on Solana devnet. Mainnet follows Phase 0 (legal entity / KYC provider / third-party security audit
funded by hackathon prize).

⚠️ Known Limitations

• App Store submission pending — iOS available via TestFlight on request.
• iOS PushKit (background VoIP) deferred — requires Apple Developer enrollment. Foreground VoIP fully functional.
• External security audit pending (Sec3 / Neodyme / OtterSec) — funded by the Solana Frontier hackathon.
• Marketplace runs on devnet only; mainnet launch contingent on Phase 0 completion.
