Polygon Technology Ecosystem

Explore the Polygon Technology Stack

Polygon has evolved from an Ethereum scaling network into a broader ecosystem spanning Polygon PoS, zero-knowledge technology, custom chain infrastructure and cross-chain interoperability. AggLayer is designed to connect different chains, while Polygon CDK provides infrastructure for launching customized chains.

More Than an EVM-Compatible Chain

Build Applications Around the Polygon Ecosystem

Polygon PoS provides an EVM-compatible environment for deploying Ethereum-compatible smart contracts with lower transaction costs and higher effective throughput than Ethereum mainnet. Developers can use familiar Ethereum tooling and deploy Solidity contracts with minimal changes.

But Polygon development is no longer limited to deploying contracts on Polygon PoS. The wider ecosystem includes AggLayer for cross-chain coordination and Polygon CDK for building customized ZK-powered chains. This gives projects different architectural options depending on their application, performance, privacy, interoperability and infrastructure requirements.

Web30 India works across this ecosystem to design and build Polygon-based products, from individual smart contracts and dApps to tokenization platforms, payment applications and customized blockchain infrastructure.

Layered Architecture

Ethereum Layer

Heimdall-v2 Layer

Bor Layer

Smart Contract Layer

Application Layer

Interoperability Layer

Ethereum Layer

Ethereum hosts Polygon's staking contracts and receives periodic checkpoints from the Polygon PoS network.

Heimdall-v2 Layer

The consensus and validation layer manages validators, staking, block producer selection, milestones and checkpoints. Heimdall-v2 is built using Cosmos SDK and CometBFT components.

Bor Layer

Bor is the block production and EVM execution layer. It executes transactions and produces Polygon PoS blocks using a rotating set of validators selected through the Heimdall layer.

Smart Contract Layer

Solidity-based smart contracts execute application logic on the EVM-compatible Polygon environment.

Application Layer

dApps, wallets, marketplaces, payment systems, tokenization platforms and other applications interact with the blockchain through RPCs, SDKs and Web3 infrastructure.

Interoperability Layer

AggLayer extends Polygon's architecture toward cross-chain interoperability by supporting asset and message movement between connected chains.

Security & Reliability

Build With Security Across Every Layer

Polygon development requires security across smart contracts, wallets, application interfaces, infrastructure and blockchain interactions.

01 // SECURITY

Smart Contract Security

Use secure Solidity patterns, access controls, input validation, reentrancy protection and appropriate testing and review processes.

02 // WALLET

Wallet Security

Protect private keys, signing operations, wallet permissions and transaction authorization.

03 // TRANSACTION

Transaction Security

Validate transaction parameters, contract interactions, token movements and administrative operations.

04 // APPLICATION

Application Security

Secure APIs, authentication, backend services, frontend interfaces and user sessions interacting with Polygon.

05 // INFRASTRUCTURE

Infrastructure Security

Protect RPC endpoints, nodes, databases, cloud environments, deployment systems and operational credentials.

06 // AUDITABILITY

Monitoring & Auditability

Track blockchain events, application activity, contract interactions, administrative operations and abnormal transaction behavior.
Polygon's own security documentation describes the use of secure coding practices, static analysis, manual review, fuzzing and formal verification where applicable in its smart-contract security processes.
