Stacks · STX
Trillions of dollars of Bitcoin mostly sits still. Stacks is the smart-contract layer built to change that — settling to Bitcoin, unlocking BTC-denominated finance, and paying its participants in the process.
Stacks is the leading smart-contract layer for Bitcoin: a chain whose blocks settle to Bitcoin itself, whose Clarity language is designed for decidable, auditable contracts, and whose sBTC asset lets Bitcoin move into applications without custodial wrapping. Its Nakamoto upgrade brought faster blocks and Bitcoin-finality guarantees, sharpening the pitch considerably.
STX is the network's asset with a mechanism unique in crypto: through Stacking (with a capital S), holders who lock STX to support consensus earn rewards paid in actual BTC — a yield denominated in the asset treasuries most want to accumulate.
The BTC-yield mechanic is the headline: Stacking rewards in Bitcoin make STX one of the only assets whose productive yield arrives as BTC — a profile with obvious appeal to a treasury already committed to Bitcoin. It's a protocol mechanism with its own risks and lockup mechanics, but the denomination is unmatched.
The thesis case rides Bitcoin-DeFi: if even a small fraction of idle BTC moves into on-chain finance, the leading Bitcoin L2 captures outsized activity — and Stacks' settlement-to-Bitcoin architecture is the conservative implementation of that idea. Entries at desk quotes; exits route via liquid pairs, settling to dollars same day.

Stacks blocks settle to the Bitcoin chain, and its consensus is anchored in Bitcoin finality — it extends Bitcoin with smart contracts rather than competing with it.
Yes — Stacking rewards are paid in BTC via the protocol's consensus mechanism. It involves locking STX for reward cycles, so model the lockup alongside the yield.
