Holdfast

Hold the stock.
Collect from those who fold.

Lock any Robinhood Stock Token for 30 to 365 days. Anyone who leaves early pays 5%, and that goes to everyone still locked. Stay to the end and you take back the full stake plus their penalties.

Longer locks take a bigger share

Penalties are split by weight: the amount locked times the multiplier of its length. Nothing else counts.

30days
×1 weight

A month. The shortest lock that still earns from leavers.

90days
×1.5 weight

A quarter, through one earnings season.

180days
×2 weight

Half a year. Twice the share of a 30-day lock.

365days
×3 weight

A full year, for conviction holds.

Pools

One pool per token, live from the contract. Locked is what holders have in; paid in is what early leavers have left behind for them so far.

The math, both ways

What leaving early costs you, and what staying earns when others leave. Rewards depend on who leaves, so the right side is an example, not a promise.

Leave early, you get back––
Stay, you get back––
Penalty you'd pay–5%, or 2.5% holding 100,000 $HFST
Your share of the pool–example: a pool of 1,000 tokens at ×1.5

Questions

Where does the yield come from?

Only from people who leave early. If nobody leaves, you get exactly your stake back. There is no other source and no token emissions.

Does my stock keep its price exposure?

Yes. The token sits in the contract, so its value moves with the stock the whole time. Holdfast only changes when you can sell.

What if I really need to get out?

Leave early at any moment. You get 95% of the stake back in the same transaction.

What if I'm the last one in a pool and leave?

Then there is nobody to pay, and the penalty goes to the treasury.

Can I add to a lock?

Each lock is separate. Open another one; it gets its own length and its own share.

Is it audited?

No. The contract is short, with unit tests and a test with the real NVDA Stock Token on a copy of mainnet.
