Smart Contracts
Governance Layer • Validators • Protocol Control
self-executing blockchain agreements
Smart contracts are self-executing agreements written in code and deployed on a blockchain. They automatically carry out actions—such as transferring funds or updating records—when predefined conditions are met, without the need for intermediaries. Smart contracts power many decentralized applications (dApps) and are foundational to DeFi, NFTs, DAOs, and other blockchain innovations.
Use Case: An insurance protocol deploys smart contracts that release automatic payouts when weather data on-chain confirms a flood, removing the need for manual claims processing or third-party verification.
Key Concepts:
- dApps — Decentralized applications built on smart contracts
- DAO — Organizations governed by smart contracts and community voting
- DeFi — Ecosystem of financial services powered by smart contracts
- NFT — Non-fungible tokens minted, traded, and secured via smart contracts
- Gas Price — The cost to execute smart contract operations
- Consensus Mechanism — How blockchains validate smart contract execution
- DeFi Risk — Vulnerabilities inherent in smart contract systems
- Trustless — The execution model smart contracts enable
Summary: Smart contracts eliminate intermediaries and enforce trustless execution. They are the building blocks of decentralized systems, enabling automation, transparency, and programmability across blockchain economies.

Smart Contract Evaluation Checklist
before interacting with any contract
☐ Contract verified on block explorer
☐ Audit completed by reputable firm
☐ No critical/high findings unresolved
☐ Track record without exploits
☐ Bug bounty program active
☐ Source code readable and documented
☐ Understand what you’re signing
☐ Check for admin keys/backdoors
☐ Review upgrade mechanisms
☐ Verify fee structures in code
☐ Confirm withdrawal paths exist
☐ Test with small amount first
☐ Use official links only (verify URL)
☐ Check contract address matches
☐ Review approval amounts
☐ Revoke unused approvals regularly
☐ Ledger for high-value transactions
☐ Simulate transaction before signing
☐ Code is law — mistakes are permanent
☐ No customer support for on-chain errors
☐ Gas costs can spike unexpectedly
☐ Oracles can fail or be manipulated
☐ Keep base in $KAG/$KAU off-chain
☐ Never trust — always verify
