Smart Contracts

Overview

Smart contracts are self-executing programs stored on a blockchain that automatically enforce agreement terms when conditions are met. Primarily written in Solidity (Ethereum/EVM) or Rust (Solana). Once deployed, code is immutable — bugs cannot be patched without migration. Security is critical as exploits are irreversible.

When to Use

Trigger conditions:

• Automating multi-party agreements that execute without intermediaries
• Building token-based systems (NFTs, DeFi, governance)
• Creating transparent, auditable business logic on-chain

When NOT to use:

• For simple CRUD operations (use a database)
• When business logic changes frequently (immutability makes updates costly)
• When off-chain data is the primary input (oracle dependency is risky)
