Polygon PoSOverview
Polygon PoS is an Ethereum-compatible sidechain for apps and transfers. Its validators finalize ordinary transactions, while Ethereum checkpoints anchor state and support withdrawals.
Compare Polygon PoS as a sidechain, not a rollup. Separate Polygon milestone finality from Ethereum checkpoints and withdrawals.
What is Polygon PoS used for?
Polygon PoS provides lower-cost, Ethereum-compatible execution for applications and asset transfers.
Use cases
- Using EVM-compatible swaps, lending, games, and token transfers on Polygon PoS.
- Paying Polygon PoS transaction fees with POL.
- Moving supported assets between Polygon PoS and Ethereum with the checkpoint and exit path understood.
Who founded and maintains Polygon PoS?
Polygon began as Matic Network, founded by Jaynti Kanani, Sandeep Nailwal, and Anurag Arjun. It later became Polygon, with Polygon Labs and the Polygon Foundation supporting its technology and ecosystem.
Protocol company
Polygon Labs
Develops Polygon technology and products, continuing work started by the Matic Network founders.
Foundation
Polygon Foundation
Supports the Polygon ecosystem and governance initiatives around the network.
What is Polygon PoS's native token?
POL is Polygon PoS's native token. It pays fees, supports validator staking, and succeeds MATIC as Polygon's protocol token.
- Fees: POL pays transaction fees on Polygon PoS.
- Security: POL is staked by validators who help secure Polygon PoS.
- Migration: POL replaced MATIC as Polygon's protocol token, though wallets and apps may still display MATIC during migration paths.

How does Polygon PoS work?
Polygon PoS is an EVM-compatible sidechain anchored to Ethereum. Heimdall milestones finalize Polygon PoS blocks, while periodic Ethereum checkpoints support state anchoring and withdrawals.
Polygon PoS runs its own proof-of-stake execution and finality while periodically anchoring state to Ethereum; it is not an Ethereum rollup.
Polygon PoS execution, finality, and Ethereum checkpoints
Polygon PoS is an EVM-compatible sidechain anchored to Ethereum. Its own milestones finalize ordinary Polygon PoS transactions; Ethereum checkpoints serve anchoring and withdrawal roles.
| Component | Role | Reader consequence |
|---|---|---|
| Bor | Executes EVM transactions and produces Polygon PoS blocks | App actions occur on Polygon PoS |
| Heimdall | Validates Bor block data and reaches milestone agreement | Milestones provide Polygon PoS finality |
| Milestone | Finalizes a sequence of Polygon PoS blocks | Ordinary finality does not wait for an Ethereum checkpoint |
| Ethereum checkpoint | Anchors a Merkle root and supports withdrawal proofs | Needed for Polygon-to-Ethereum exits, not every on-chain action |

Apps, tools, and built-in features on Polygon PoS
Polygon PoS runs Ethereum-style apps, so familiar Ethereum contracts and wallet connections can usually be adapted to it.
- Tools and language: Solidity or Vyper, with Ethereum wallets and common EVM development tools.
- Trade-off: it is similar to Ethereum, BNB Chain, and Avalanche's C-Chain for compatibility, but Polygon PoS is only one product in the wider Polygon ecosystem.

What are Polygon PoS's trade-offs?
Polygon PoS offers an Ethereum-compatible app environment, but it is only one network in the broader Polygon product family.
- Transaction experience: Polygon PoS supports EVM app actions such as swaps, lending, and token transfers; its current fee and confirmation experience should be compared on Polygon PoS itself.
- Compatibility: Solidity, Ethereum wallets, and EVM tools make it comparable with BNB Chain and Avalanche's C-Chain as well as Ethereum Layer 2s.
- Security and scope: Its validator and Ethereum-checkpoint design differs from Ethereum mainnet, and Polygon PoS figures do not describe Polygon zkEVM or other Polygon chains.
Common questions about Polygon PoS
Is POL a good investment?
POL is Polygon PoS's native token. It pays fees, supports validator staking, and succeeds MATIC as Polygon's protocol token. This profile does not contain current comparable price, liquidity, supply, exchange-access, governance-concentration, or regulatory evidence, so it cannot determine whether POL is a good investment.
What should I verify before comparing Polygon PoS?
Verify whether the claim refers to Polygon PoS, Polygon zkEVM, or another Polygon network. Use the same transaction type, asset route, confirmation target, and observation window when comparing Polygon PoS with another network.
