Rent a box.
Pick what goes in it. Collect a fee every time someone opens or closes it. You never touch the money. That is the whole point of the box.
Safe deposit rental agreement
1.
The box gets a name on the plate.
Short one for the ticker, up to ten characters. Long one for the engraving, up to thirty-two.
2.
The box holds what you say it holds.
Up to ten coins. Shares must add to one hundred. The keeper buys them in these proportions and rebalances toward them over time.
Coin, by mint addressShare
0.00% of 100. It has to add up.
3.
You take a fee, in and out.
Charged on every deposit and every withdrawal, paid to you in SOL on the spot. Up to one percent. The house takes 0.10% on top, always.
4.
You can change the contents. You cannot touch the money.
Amend the schedule whenever you like from the box's page. Deposits go to the program, the keeper does the trading, and nothing in this agreement gives you, the house, or the keeper a way to withdraw.
