Smart contracts enable users to encode business logic into executable code that runs on decentralized ledgers like blockchains. These platforms empower developers to deploy powerful applications across finance, supply chain management, and voting systems with transparency and tamper-proof execution.
What Are Smart Contract Platforms?
Smart contracts are self-executing programs that automate agreements when predefined conditions are met, eliminating the need for intermediaries. According to Lata Varghese of Protiviti:
"A smart contract is a digital form of a traditional contract where agreements are inscribed as code."
Key components of smart contract platforms include:
- Decentralized execution via blockchain consensus.
- Secure storage of contract code.
- Tools like Ethereum Virtual Machine (EVM) for deterministic execution.

Layers of Smart Contract Platforms
Level 1 (L1) Platforms
Execute contracts directly on the main blockchain. Examples:
- Ethereum
- Solana
- Cardano
Level 2 (L2) Platforms
Optimize efficiency by processing contracts off-chain before settling on L1. Examples:
- Polygon
- Optimism
Most modern platforms support both L1 and L2 functionalities.
