Polygon is one of the oldest and most widely adopted Ethereum scaling solutions. What started as a simple sidechain (Matic) has evolved into an ecosystem of ZK-powered chains under the Polygon 2.0 vision.
A Brief History
2017: Matic Network founded — an Ethereum sidechain with faster, cheaper transactions.
2021: Rebranded to Polygon. Expanded from a single sidechain to a multi-chain ecosystem.
2023: Polygon 2.0 announced — a transition from Matic to POL token and a shift toward ZK rollup technology.
2024: MATIC → POL token migration completed. Polygon PoS chain continues, Polygon zkEVM live.
2026: Polygon operates two main networks: Polygon PoS (legacy, high adoption) and Polygon zkEVM (newer, stronger security guarantees).
Polygon PoS vs. Polygon zkEVM
Polygon PoS — The original chain. A sidechain secured by its own validator set, not fully inheriting Ethereum's security. Extremely cheap (~$0.001–0.01 per transaction). Hosts the widest range of DeFi apps with years of deployment history.
Polygon zkEVM — A ZK rollup. Transactions are verified with zero-knowledge proofs and posted to Ethereum mainnet. Inherits Ethereum's security (unlike the PoS chain). Slightly higher fees than PoS but meaningfully lower than Ethereum mainnet.
The distinction matters: PoS is a sidechain (different security model), zkEVM is a true L2.
POL Token
POL replaced MATIC as the native token of the Polygon ecosystem. Its uses:
- Gas fees on Polygon PoS and zkEVM
- Staking — Validators stake POL to secure Polygon PoS
- Governance — POL holders vote on protocol parameters
- Super-staking (Polygon 2.0) — Validators can secure multiple Polygon chains simultaneously, earning fees from each
If you held MATIC, the migration to POL was 1:1 — most wallets and exchanges handled it automatically.
Polygon in 2026: Where It Stands
Polygon PoS remains popular because of its history and low fees. Many applications deployed there years ago haven't migrated. It has:
- Quickswap (DEX), Aave (lending), Curve (stable AMM)
- Gaming projects (many chose Polygon for low fees)
- Large Coinbase-connected ecosystem
vs. Base: Base has faster growth, stronger VC/developer mindshare, native Coinbase integration. Many new projects choose Base over Polygon.
vs. Arbitrum: Arbitrum has deeper DeFi TVL and stronger security guarantees (true L2 with fraud proofs). Higher fees than Polygon PoS but more battle-tested.
vs. zkSync/Starknet: Other ZK chains; all competing in the same ZK rollup space as Polygon zkEVM.
Getting Started on Polygon
- Add Polygon PoS to MetaMask (Chain ID: 137, RPC: polygon-rpc.com)
- Bridge ETH or USDC from Ethereum mainnet via the official Polygon bridge (wallet.polygon.technology) or Across Protocol
- Get MATIC/POL for gas — most bridges include a small gas top-up
Or: buy USDC and withdraw from Coinbase directly to Polygon PoS.
Should You Use Polygon in 2026?
For new DeFi activity: Base or Arbitrum typically have better current liquidity and developer activity for new applications.
For existing Polygon apps: PoS is perfectly functional and cheap — no reason to leave if what you use is there.
For ZK rollup exposure: Polygon zkEVM, zkSync, and Starknet all offer the stronger security model. Choice depends on which apps you want to use.
