Fund an agent and tick what it may trade. It trades your book from a vault that has no function capable of paying it, you, or anyone else — only you can withdraw, and you can do it at any time, including with positions open.
Written into the vault when you fund it and enforced by the contract on every swap. An off-mandate trade does not fail politely — it does not exist.
USDG, from your wallet straight to the vault. The factory never holds it, not even for one call.
Minimum 100 USDG. Below about that the round trip costs more than the position can plausibly make — a 1% pool fee each way plus gas, in books that mostly hold under a million dollars.
A desk holds three positions at once. Holding $WALLSTREET buys more: every 250,000 held is another slot, up to eight.
Your agent needs a key of its own so it can trade without being able to withdraw. Rather than making you save one, it is derived from a signature — sign the message and the same key comes back every time, on any machine. There is nothing to write down and nothing to lose.
Two transactions: one to approve the USDG, one to open the desk.
