Polygon.

Scaling tools and networks for Ethereum.

Polygon is an ecosystem of networks and tools designed to make Ethereum-based activity faster or cheaper. POL is the ecosystem's token; older material may refer to MATIC.

2017 — Matic Network founded; 2020 — Polygon PoS mainnet era

Built by: Jaynti Kanani, Sandeep Nailwal, and Anurag Arjun

Polygon started as Matic Network and expanded into a family of Ethereum scaling technologies. Its ecosystem token is transitioning in many contexts from MATIC to POL.

Why it stands apart

Scaling tools and networks for Ethereum.

“Polygon” is not one security model: Polygon PoS, bridges, and zero-knowledge products have different designs and risks.

Bottom line: Polygon has its own design, trade-offs, and risks. Learn the network before you use the asset.

Follow the money

What happens after you hit send.

A user signs a transaction on the chosen Polygon network.
Validators order and execute it under that network's rules.
Bridges, when used, lock or represent assets across networks and add another trust/technical layer.

Know the economics

Where new POL comes from.

Token supply and migration details depend on the MATIC/POL upgrade path and the product being used.

Protect the downside

The mistake you cannot undo.

Know whether you are on Ethereum, Polygon PoS, or another Polygon product. Bridges and token migrations are high-risk moments for phishing.

Go beyond the summary

The subject in plain English.

Polygon is a separate system with its own rules, people, and trade-offs. This page explains the basics in plain English so you can understand it before deciding whether to use it.

Start with the plain version

Polygon is an ecosystem of networks and tools designed to make Ethereum-based activity faster or cheaper. POL is the ecosystem's token; older material may refer to MATIC.

Its birthday and backstory

2017 — Matic Network founded; 2020 — Polygon PoS mainnet era. Polygon started as Matic Network and expanded into a family of Ethereum scaling technologies. Its ecosystem token is transitioning in many contexts from MATIC to POL.

Who is behind it?

Jaynti Kanani, Sandeep Nailwal, and Anurag Arjun. Names can explain a project’s history, but they do not make an asset safe or guarantee its future.

What keeps the record

Polygon uses Varies by Polygon network. Different Polygon products have different security models. Always check which network, token standard, and bridge you are using.

Supply, fees, and incentives

Token supply and migration details depend on the MATIC/POL upgrade path and the product being used.

The part to take seriously

Know whether you are on Ethereum, Polygon PoS, or another Polygon product. Bridges and token migrations are high-risk moments for phishing.

What people use it for

Where this matters.

Learn how the network records activity
Understand the difference between the asset, the network, and the company around it
Recognize the correct network before a transfer
Check whether a wallet or service actually supports this asset

Before you act

Verify before you sign.

Find the project through an official link, not an ad, reply, or direct message.
Confirm the exact name, ticker, network, and token or contract address.
Do not share a recovery phrase, private key, or remote access with anyone.
Use a small test transaction before moving an amount that matters.
Treat every purchase, yield offer, or app approval as a separate risk decision.

Polygon uses Varies by Polygon network. “Polygon” is not one security model: Polygon PoS, bridges, and zero-knowledge products have different designs and risks.

What is the safest first step? +

Read the official documentation, verify the correct network, and make a tiny test before connecting a meaningful wallet or sending a meaningful amount.
