feat: add AlgoVoi wallet provider

[chopmob-cloud]

Summary

• Adds AlgoVoi as a named wallet provider (WalletId.ALGOVOI)
• AlgoVoi is an Algorand + Voi browser extension wallet with native x402 HTTP payment support
• The implementation calls the ARC-0027 compliant window.algorand provider directly — no external SDK dependency required
• Extension: AlgoVoi on GitHub

Changes

• types.ts — Add ALGOVOI = 'algovoi' to WalletId enum, WalletMap, and WalletOptionsMap
• algovoi.ts — New AlgoVoiWallet class extending BaseWallet
  • Detects the extension via window.algorand?.isAlgoVoi === true
  • Falls back to listening for algorand#initialized event if not yet injected
  • Implements connect(), disconnect(), resumeSession(), signTransactions()
  • Handles both algosdk.Transaction[] and Uint8Array[] input formats
  • 3-minute timeout for provider detection
• index.ts — Export AlgoVoiWallet
• utils.ts — Register in createWalletMap()
• algovoi.test.ts — Unit tests for connect, disconnect, resumeSession, metadata

dApp usage

import { WalletId, WalletManager } from '@txnlab/use-wallet'

const walletManager = new WalletManager({
  wallets: [WalletId.ALGOVOI, WalletId.PERA, WalletId.DEFLY]
})

Test plan

• All 475 existing tests pass (no regressions)
• New AlgoVoi tests pass (connect, disconnect, resumeSession, metadata)
• pnpm build succeeds for @txnlab/use-wallet package
• Manual: Install AlgoVoi extension + test with a dApp using use-wallet

Hey @drichar — just wanted to check in on this one. AlgoVoi is a browser extension wallet for Algorand and Voi with native ARC-27 support, and getting it into use-wallet would really help with dApp compatibility across the ecosystem (a few Voi dApps are already waiting on this to land before they can add AlgoVoi support).

No pressure at all — just appreciate any review when you get a chance. Happy to address any feedback or changes needed. 🙏

Bumping this for visibility — wanted to share some context on where this fits in a wider rollout.

What's shipped since this PR was opened

Since submitting this PR, AlgoVoi has launched full implementations across three payment protocols:

Protocol	Status	Links
x402 (HTTP Payment Protocol, spec v1)	✅ live	x402.org ecosystem listing #2022
MPP (IETF draft-ryan-httpauth-payment)	✅ live	tempoxyz/mpp #556
AP2 (Agentic Commerce, AP2 v0.1)	✅ live	google-agentic-commerce/AP2 #218

All three are smoke-tested with real on-chain USDC payments across Algorand, VOI, Hedera, and Stellar.

eCommerce platform adapters

AlgoVoi also has payment gateway adapters for 17+ eCommerce platforms (WooCommerce, Shopify, PrestaShop, Magento, OpenCart, and more), all open-source:

Why use-wallet matters here

The AlgoVoi browser extension is the user-facing wallet that completes the loop — dApps built with use-wallet can sign the on-chain payment transactions that x402/MPP/AP2 require. Without WalletId.ALGOVOI in use-wallet, dApp developers building payment-gated flows on Algorand have to roll their own integration.

Happy to answer any questions or make changes if the implementation needs adjusting for the v4 API.
