Mandate —— Safe Automation for Tokenized Assets

Mandate is a policy firewall for AI-agent finance. It lets a user fund a MandateAccount, while an AI/demo agent can only act through a constrained session key. Every proposed financial action is checked onchain before execution against asset, adapter, trade-size, turnover, exposure, nonce, deadline, and signed price-row constraints.

The demo shows two paths on Robinhood Chain testnet: a small TSLA buy that is approved and executed after policy preview returns OK, and a dangerous 500 USDG → TSLA action that is blocked because it exceeds the exposure boundary. The agent can propose, Mandate decides, and transaction receipts prove the outcome.

During the Buildathon, I built the full Mandate MVP: smart contracts, deployment on Robinhood Chain testnet, a public landing page, and a live demo console.

Implemented features include:

• MandateAccount policy engine

• MockERC20 demo assets: USDG, TSLA, AMD

• MockAMM and approved swap adapter

• signed demo price feed

• server-side price signer API

• server-side demo-agent relayer using a constrained session key

• wallet-based mint / approve / deposit flow

• policy preview before execution

• approved safe action execution

• blocked dangerous action proof

• activity/evidence UI with transaction links

The live demo successfully demonstrates that user funds remain in MandateAccount, the agent does not hold the owner key, approved actions can execute, and out-of-policy actions are blocked before funds move.

Mandate is currently unfunded and independently built. No institutional or external funding has been raised.
