Manda gives personal AI agents revocable payment authority from a human-owned smart account. Owner-set rules limit who they can pay, how much and how often; eligible network gas is sponsored.
Manda gives personal AI agents payment authority without giving them the human's wallet key. A person owns and funds an ERC-4337 Modular Account V2. Their agent uses a separate delegated key and Manda's authenticated HTTPS API to request payments.
The owner defines the mandate: approved network and recipients, a per-payment ceiling, a UTC daily budget, a cumulative onchain cap, an auto-approval threshold, and expiry. Manda checks policy before building a UserOperation. Eligible network gas is sponsored; the payment itself always comes from the owner's smart account. The owner can inspect attributed activity and revoke delegated authority.
This is a working testnet build. The production Vercel frontend connects to an authenticated VPS agent service. An Arbitrum Sepolia payment made through that service was confirmed onchain in transaction 0x166bb92cb97c3b15947289a88bcd04f37fce41b82db03c8f6de7c7e92ace9ea3. A separate request one wei above the configured per-payment cap returned HTTP 403 PAYMENT_LIMIT_EXCEEDED without creating a transaction. Robinhood Chain Testnet has a separate historically confirmed payment; its previous mandate has since expired.
Developers can connect an existing AI runtime through the narrow agent API using a request ID, recipient, amount, asset, and chain. The owner key stays outside the agent service and browser. The repository includes the source, setup instructions, security boundaries, 29 passing tests, current screenshots, sanitized API and RPC evidence, and a 97-second demo video.
Manda composes deployed Modular Account V2 validation modules rather than claiming a bespoke audited Solidity contract. USDG policy and payment support is implemented in code, but live USDG execution and owner-signed onchain revocation have not yet been demonstrated. The current product uses testnet funds and does not route or bridge payments automatically.
We shipped a live Vercel frontend and authenticated agent API backed by a VPS service. A human-owned Modular Account V2 and delegated agent mandate execute sponsored payments on Arbitrum Sepolia; Robinhood Chain Testnet has a separate confirmed historical payment path. The production API confirmed an Arbitrum payment onchain and rejected an over-limit request with HTTP 403 before creating a transaction. We published a 97-second proof video, current screenshots, sanitized API and RPC evidence, and reproducible source with 29 passing tests. USDG support exists in code but has not been demonstrated live; owner-signed onchain revocation also remains unverified.
Not currently fundraising. Manda is a testnet prototype being developed into a safe payment interface for personal AI agents.
