Learn CLARITY with Real Code Examples

Interpreted smart contracts executed on Stacks nodes

Contracts interact with Stacks ledger and Bitcoin

Decidability ensures predictable execution

Data storage on-chain with maps and tuples

Events and state changes tracked deterministically

Clarity source -> Interpreted execution on Stacks

Public/private functions define external/internal API

State stored in maps, lists, tuples

ok/err for error handling

Deterministic interaction with blockchain state

Functional, immutable state

Decidable loops and conditions

Contract-to-contract calls

Error handling via ok/err

Structured storage via maps/tuples

STX token transfers

NFT minting/trading platforms

Decentralized voting/governance

Escrow contracts

Predictable DeFi protocols

Decidability and predictability

Functional programming approach

Integration with Bitcoin

Strong type system

Security-first contract design

Keep loops bounded

Optimize map/tuple usage

Deploy multiple small contracts instead of one monolith
