Shijima in one screen
What it is, what it does for you, and what it will never do.
Shijima gives you an AI agent that looks after a basket of US Stock Tokens on Robinhood Chain. You put in USDG, a digital dollar. You pick a strategy, such as The giants or The whole US market. Your agent keeps your money on that plan around the clock, including nights and weekends when New York is shut.
Shijima (しじま) is the stillness of deep night: the hours when nothing moves and no one is watching. Those are the hours it works.
You put in $100 and pick a basket that is 40% Nvidia, 30% an S&P 500 fund and 30% cash. Your agent buys about $40 of Nvidia and $30 of the fund, and keeps $30 as cash.
On Saturday Nvidia jumps. Your $40 is now worth $48, which is 44% of your money, not 40%. Your agent notices, works out that about $4.80 should be sold to get back to plan, and decides when to sell it: now, part now, after New York reopens, or not at all. It tells you why.
You decide, it times
| You decide | Your agent decides |
|---|---|
| What to hold, and in what shares | When to move back to your plan |
| The most per trade and per day | Whether to do all of it, part of it, or wait |
| When it stops after a loss | Nothing else |
It never picks a stock, never predicts a price, and never adds a holding you did not choose.
Why the nights and weekends
The US market is shut for most of the week. Stock Tokens keep trading on Robinhood Chain anyway. On weekends nobody can create or redeem them, so nothing ties a token's price to the real stock, and prices drift. Real money trades in those hours. Your agent is the one watching yours.
What you can check
- Your money is in your own contract. Only your wallet can take it out, and only to itself. What it can and cannot do.
- Your limits are held by the chain. A trade over them is refused by the network, not by our goodwill. Limits.
- Every decision is written down, with its reasons, and its fingerprint goes on the chain with the trade. Anyone can press Check it. The record.
Stock Tokens are not shares
A Stock Token follows a US stock's price. It gives you no ownership of the company and no shareholder rights. People in the US, the UK, Canada, Switzerland and some other places may not hold them.
