i
Modular

Bond markets, staking and wrapping are separate contracts. Upgrade one wall without touching the keep.

ii
Reserve-backed

Every KSTL is backed by $11.96 of treasury assets — stablecoins, ETH, BTC and owned liquidity.

iii
Open

Integrations, analytics and SDKs for builders, DAOs and institutions. Fork-friendly, credit appreciated.

Tokens Three forms of the same stone
A stone coin carved with the Kastle tower
KSTL
The stone

Reserve currency. Minted only when the treasury receives more than it issues. Backed, never pegged.

sKSTL
The garrison

Staked KSTL. Your balance grows every epoch as rebases are distributed to those holding the walls.

gKSTL
The seal

Wrapped sKSTL. Its quantity stays fixed while its value tracks the index — made for bridges, vaults and lending markets.

The loop One epoch, every eight hours

Bond, hold, stake. Repeat until it's a fortress.
