Stacks

Stacks is a Bitcoin Layer 2 for smart contracts and dApps that extends Bitcoin without changing its base protocol. It anchors to Bitcoin through Proof of Transfer and is designed to give applications Bitcoin-grade settlement while using the Clarity language for deterministic, security-oriented smart contracts.

With upgrades such as Nakamoto and the introduction of sBTC, Stacks is becoming a stronger foundation for Bitcoin DeFi, NFTs, social products, and BTC-native application logic. It is especially relevant for teams that want to combine Bitcoin liquidity with programmable smart contracts.

If you want to launch a BTC-based DeFi protocol, payment service, NFT application, or social Web3 product on Stacks, FreeBlock can deliver the project from Clarity architecture and smart contracts to ecosystem integration and interface design.
