Stocks, sealed.
A real tokenized share, locked 1:1 inside a block and issued as a graded certificate. The grade is not a judgement — it is a clock.
Grade clock · simulation
Pick a slab, then let it sit. The grade is the only thing time can buy here.
01 · Why a tombstone
When a deal closes, the bankers get a lucite tombstone: a block of clear acrylic with the terms engraved inside. It does nothing. It just proves you were there.
02 · The grade is a clock
Every graded market grades condition — how well an object survived. This one grades how long you left it alone. Sealed longer, graded higher, and the grade is what sets your share of the fees.
Nobody decides what is rare. It gets earned, or it gets given up.
03 · Cracking
You can crack a slab at any block. The share comes back to you whole and immediately — it never left, that is the entire point of the block.
What you forfeit is the grade, and it does not resume. Re-sealing the same share starts the clock at zero. That asymmetry is the mechanism; without it, a grade would just be a timestamp anyone could farm.
Status
Nothing is deployed. No token, no vault, no slabs, no grades. The case above is a simulation and is labelled as one.
What is inside a block
One tokenized share on Robinhood Chain, held 1:1. Not a claim on a basket, not a synthetic, not a wrapper that can be diluted: the specific share you sealed, and the contract cannot spend it.
The grades
Freshly sealed grades 6. Twenty-four hours grades 7, three days grades 8, seven days grades 9, and thirty unbroken days grades MINT. The thresholds are compile-time constants with no setter.
Thirty days is the ceiling on purpose. This is a chain where a week is a long time — a ladder topping out at three years would be a ladder nobody ever climbs, and an unreachable top grade is decoration, not a mechanism.
