Changelog

Release history for all EmbarkAI SDK packages.

Versions are tracked independently per package. Source repositories: @embarkai/core , @embarkai/ui-kit , @embarkai/mcp .

2026-03-10

@embarkai/core v0.3.1  — AAD Binding for Server Wallet Vault

  • AAD binding for server wallet vault encryption — Upgrade server wallet backup encryption from v1 (no AAD) to v2 with AES-GCM additionalData binding. Prevents metadata tampering attacks on stored envelopes.
  • Encrypt with canonical sorted AAD keys and deviceId embarkai-server-wallet
  • Decrypt with 3-level fallback: canonical → legacy key order → no AAD (v1)

@embarkai/core v0.3.0  — Companion Release

  • Version bump to align with ui-kit v0.3.0 (envelope encryption v2).

@embarkai/ui-kit v0.3.4  — Canonical AAD Key Order

  • Fix canonical AAD key order — serializeAad() now sorts keys alphabetically for deterministic AES-GCM additionalData. Decrypt functions try canonical order first, then fall back to legacy key order for pre-fix v2 backups.

@embarkai/ui-kit v0.3.3  — WalletConnect Flow Reliability

  • Remove duplicate WagmiProvider to fix session conflicts
  • Reactive disconnect flow using useEffect instead of setTimeout
  • Guard stale session triggers with modalWasOpened flag
  • Loading spinner in auth dialog while awaiting wallet signature
  • Increased timeouts: signature 120s, session 5 minutes

@embarkai/ui-kit v0.3.2  — Modal Close Detection Fix

  • Fix false modal-close detection — Track whether RainbowKit modal was actually opened before detecting its closure.

@embarkai/ui-kit v0.3.1  — Wallet Login via WalletConnect

  • Wallet login auth flow — Sign in with external wallets via WalletConnect
  • Auto-clear stale WalletConnect sessions with timeout feedback

@embarkai/ui-kit v0.3.0  — Envelope Encryption v2 & Session Fix

  • Envelope encryption v2 — Bind AAD as real AES-GCM additionalData in backup encryption (schemaVersion 2), preventing metadata tampering
  • Fix stale session on keyshare recovery

@embarkai/ui-kit v0.2.8  — Iframe Communication Fixes

  • Fix channelToken race condition in iframe communication
  • Support both LUMIA_PASSPORT_* and IFRAME_MSG_* message types for backwards compatibility

  • Wallet metadata — Shows wallet name (e.g. “MetaMask”) instead of generic “Wallet” label
  • Consistent address truncation format (0xABCD...1234)
  • Fix lucide-react bare import leaking into iframe bundle
  • Sync iframe ↔ SDK message types after rebranding
