Floor documentation

What Floor is

You can now hold stocks like NVIDIA and the Nasdaq-100 as tokens on BNB Chain. A bad year can cut the value by a third. In NVDA's worst year since 2018 (2022), holding lost 51%.

Today you have two choices. Sell and miss the upside. Or hold and hope. Floor adds a third: hold, with a floor.

You deposit USDT only, pick a basket and choose the lowest value you accept, for example 90% of your deposit, for a one-year term. A vault contract then holds stock when your cushion is big and moves into USDT when it is small. Each move is a normal swap on BNB Chain. The rule is described on How it works.

Protection is not free. You keep part of the gain: roughly 4 × (100 − floor)%, so about 40% at a 90% floor. See The trade-off. The floor holds unless prices gap more than about 24% before the vault can rebalance; it is not a guarantee. At a 90% floor, 0.44% of historical one-year windows ended more than 1 point below it. See Risks and Known open items.

Floor uses spot trades only: no perps, options, leverage or borrowing.
