What's new in v0.5.0

AI Agent Chat (Voi chain · Agents tab)

Natural-language wallet assistant powered by Claude Sonnet 4 via the UluMCP server.

  • Direct actions — structured commands bypass AI entirely (zero token cost):
    • swap 10 VOI for USDC · send 5 VOI to alice.voi · balance · price of VIA
    • resolve nugget.voi · register mynewname.voi
  • AI fallback — conversational and ambiguous queries use Claude Sonnet 4 with a per-category tool whitelist
  • Categories: tokens · NFTs · swaps · names · lending · general
  • Anthropic API key lives exclusively on the UluMCP server — never bundled in the extension
  • Single Sign & Send — swap groups (approve + swap + withdraw) merged into one button, one click

Coinbase Onramp (Algorand chain · Assets tab)

Buy ALGO directly from the wallet via the Buy button.

  • Secure session-token flow: wallet address POSTed to AlgoVoi backend, never in URL parameters
  • Satisfies Coinbase "require secure initialization" — one-time session token from backend
  • CORS restricted to chrome-extension:// origin
  • Feature-flagged via COINBASE_ONRAMP_ENABLED — pending Coinbase UK country approval

Auto-update notifications

Extension checks for new releases via the MCP server and shows an amber banner with a download link when a newer version is available. No new permissions required.

  • Checks on startup + daily via Chrome alarm
  • Server-side /version endpoint auto-syncs from GitHub releases every 30 minutes
  • Amber "UPD" badge on extension icon when update available

UX improvements

  • Account removal confirmation modal — replaces native window.confirm with in-app styled modal showing account name, address, and backup warning (#1)
  • Single sign button for swap groups — multi-transaction swaps now show one "Sign & Send (N txns)" button instead of separate buttons per transaction

Bug fixes

  • Import mnemonic on empty-wallet view — the Import Mnemonic button on the empty-wallet screen was non-functional (modal not rendered in early return path). Users were forced through full wallet setup which silently wiped existing accounts on other chains.
  • Three approval popups per swap — direct-action tool calls (snowball_tokens, humble_pools, humble_swap_txn) were each hitting x402 payment gates, opening a separate approval popup per call. Server now exempts extension tool calls from x402.

MCP tools expanded

50 tools across 11 modules: arc200 · arc72 · envoi · humble · snowball · swap200 · marketplace · txns · dorkfi · x402 · algod · chat
