Robinhood Chain · USDG · stock tokens

A purser for
your agents.

Every agent gets a book: USDG to spend, tokenized stocks to hold, ceilings a human set. The purser pays the bills, files the receipts and keeps the float working. The money never sits with us.

Building on Robinhood Chain, chain id 4663. Funded by $PURSER, paired with NVDA.

The book

Three lines. Spend, hold, earn.

I

Spend USDG for the bills.

The agent calls a paid API, a model, a dataset. The purser reads the price, checks the ceilings, pays in USDG from the agent's own wallet and files the receipt. No card, no prepaid credits a person has to top up.

II

Hold Stock tokens for the float.

Whatever the agent does not need this week sits in tokenized stocks on Robinhood Chain instead of idling. NVDA, TSLA, SPY, AAPL. Sold back into USDG the moment a bill comes due, under the same ceilings.

III

Earn Get paid by other agents.

Put a price on your own service and the purser makes it payable in USDG by any other agent. Revenue lands in the same book, next to the spend and the float.

The float

Idle USDG becomes stock. Stock becomes USDG when a bill comes due.

Tokenized stocks on Robinhood Chain trade around the clock against USDG, so an agent's spare balance can sit in NVDA on Tuesday night and pay for inference on Wednesday morning. Which tickers and how much is on the policy sheet, not up to the agent.

Stock tokens are issued on Robinhood Chain. Availability and hours follow the issuer; nothing here is investment advice.

The policy sheet

The agent asks. The wallet answers.

A prompt can talk an agent into anything. It cannot talk a wallet past a line a human wrote on this sheet. The purser enforces the sheet; the agent only ever sees what is left.

$PURSER×NVDA
Token

$PURSER funds the build, paired with NVDA.

Launched on Robinhood Chain against a stock token rather than ETH. 1% per trade, all of it to development, dev wallet locked behind a vote. The contract address is published on one page only.

Directory

What an agent can buy today.

Pay-per-call APIs, models and datasets, with a price and a probe result from us rather than a claim from the vendor. The purser will settle these in USDG; until then, the directory is a free public API for anyone.
