Automatic
x402 payments
AlgoVoi intercepts HTTP 402 responses and handles micropayments invisibly — no copy-paste, no manual steps. Just browse and pay.
Building a site that charges x402 payments? AlgoVoi is also a hosted tenant platform — register your resource, get a payout address, and start accepting payments without running your own chain nodes or verification servers.

Protocol (MPP)
MPP is an open standard for machine-readable payment challenges over HTTP. AlgoVoi intercepts WWW-Authenticate: Payment headers, builds and signs an AVM transaction, then injects the resultingAuthorization: Payment credential for seamless retry — no manual steps.
Built for
AI agents
Chat with an AI assistant that can swap tokens, resolve names, check balances, and explore DeFi — all from inside the wallet. Plus WalletConnect and AP2 for programmatic agent signing.
algo_signTxnSend any
token or ASA
Native coins, ASA tokens, HTS tokens, and ERC-20s in one unified send flow across Algorand, Voi, Hedera, Base, Arc, and Tempo. Resolve .voi names instead of pasting long addresses.
Send USDC
×DEX swaps across
