Adding Polygon (MATIC) to MetaMask 🚀

Polygon has grown into something special. A multi-chain system that makes Ethereum better. Now in Q4 2025, getting Polygon on your MetaMask? Kind of essential if you want the full Web3 experience.

What's Polygon, anyway? 🌉

It used to be Matic Network. Now it's this layer-2 thing for Ethereum. Works with Ethereum seamlessly. Assets move back and forth. Developers can jump ship easily. Users get tons of dApps.

It runs on a tweaked Proof of Stake. Fast transactions. Nice interface. Seems pretty secure too. People love it for all kinds of crypto stuff.

What's new in the Polygon world 🔥

2025's been huge. Building on what happened in 2023-2024:

• Gaming & NFTs: They're crushing it. More Web3 games than anybody else. Big partnerships everywhere.

• zkEVM stuff: Launched back in March 2023. Crazy transaction volumes now. Bridge activity through the roof.

• Transactions exploding: The network handles 20 million transactions daily. Half a billion unique addresses this year. Not too shabby.

• Polygon 2.0: They've done it. ZK-powered supernetwork is live. Works with Ethereum instantly. MATIC became POL. Token holders can validate now.

• Big companies jumped in: Partnerships all over the place. Supply chains. DeFi platforms. You name it.
