# Purser

> A purser for your agents, on Robinhood Chain. 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.

Purser gives an AI agent a book on Robinhood Chain (chain id 4663): USDG to spend on pay-per-call services, tokenized stocks (NVDA, TSLA, SPY, AAPL and others) to hold as float, and a policy sheet a human signs once: ceilings per call and per day, allowed counterparties, an approval threshold, a kill switch. The purser pays bills from the agent's own wallet, files receipts, sells float back to USDG when a bill comes due. Non-custodial; the money never sits with us. Funded by the $PURSER token on Robinhood Chain, paired with NVDA.

## What is in build
