About this extension
AlgoVoi — Algorand & Voi Web3 Wallet

AlgoVoi is a non-custodial browser wallet for the Algorand and Voi blockchains. Built for power users, developers, and AI agents — all in a single lightweight Chrome extension.

🔐 Vault Security
Your keys never leave your device. The encrypted vault uses PBKDF2 (600,000 iterations) + AES-GCM-256 — the same standard used in password managers. Import via 25-word mnemonic or connect your existing mobile wallet.

💸 Send & Receive
Send ALGO, VOI, and any ASA token across both mainnets simultaneously. No chain switching — AlgoVoi handles both networks natively.

📱 Mobile Wallet Pairing
Connect Pera Wallet, Defly, or Voi Wallet via WalletConnect QR pairing. Sign transactions from your favourite mobile wallet without exposing your keys to the browser.

🌐 dApp Ready
Full ARC-0027 support via window.algorand — compatible with any Algorand or Voi dApp out of the box.

⚡ x402 Micropayments
Native x402 HTTP payment protocol support. Browse x402-gated content and APIs without interruption — payments are detected, approved, and submitted automatically in the background.

🔩 MPP (Machine Payments Protocol)
Full support for the WWW-Authenticate Payment header protocol (mpp.dev). AlgoVoi intercepts 402 responses, presents the charge for approval, then builds and submits a signed AVM transaction — returning the Authorization credential for seamless content retry.

🤝 AP2 (Agent Payments Protocol)
First-class support for Google's Agentic Commerce AP2 standard. AlgoVoi acts as a credentials provider — verifying CartMandates from merchants and AI agents, presenting them for user approval, and signing PaymentMandates using your wallet key. Agents handle settlement; you stay in control.

🤖 AI Agent Signing
Connect AI agents to AlgoVoi via WalletConnect. Agents request transaction signing through a secure approval flow — you remain in full control, agents never touch your keys.

🔖 .voi Name Resolution
Send to human-readable .voi names powered by the enVoi name service.
