Polygon POL

It became POL in September 2024, one for one, as part of a broader redesign of how the token works across Polygon's networks. Same project, same quantity, new name and new plumbing. Coins on Polygon's own chain converted automatically; coins held on Ethereum or in cold storage need putting through the official migration tool. Exchanges by and large converted customer balances themselves, which is one of the few times leaving coins on an exchange made life easier.

Check where it is. On an exchange: almost certainly converted already, and your balance shows POL. In your own wallet on the Polygon network: converted automatically. In your own wallet on Ethereum, which is where early buyers often held it: still MATIC, and you migrate it yourself with the tool on Polygon's official site. Use only the official tool, reached by typing the address yourself: token migrations are a favourite costume for phishing sites.

It absorbs activity that Ethereum itself would price out. Transactions run on Polygon's networks for fractions of a penny, with the results anchored back so they benefit from Ethereum's deeper security. Think of Ethereum as a courtroom and Polygon as the arbitration office next door: most disputes settle in the cheap fast room, and the courtroom's authority is what makes the arbitration meaningful.

A way to prove work was done without showing the working. One computer performs thousands of transactions, then produces a compact mathematical receipt that convinces everyone else the whole batch was processed honestly, without them re-running any of it. That receipt is small and cheap to check, which is the entire trick: heavy work happens off to the side, and only the proof lands on the expensive chain. Polygon bet earlier and heavier on this than most.

Cost and familiarity. It ran the tools their developers already knew from Ethereum, at consumer-friendly prices, back when the alternatives were expensive or exotic. Hence Reddit's collectible avatars, Starbucks' loyalty experiment and Nike's projects landing there. Honest postscript: many of those experiments have since wound down, which says as much about brands' crypto enthusiasm cooling as it does about Polygon. The rails worked; the fashions moved.

Its main network is technically a sidechain: it secures itself with its own validators and staked POL rather than inheriting Ethereum's security wholesale, which is what the strict definition of Layer 2 requires. Its newer zero-knowledge networks fit the strict definition better. This distinction fuels endless online arguments and matters mainly at the extremes: in a catastrophe, where your transaction's guarantees ultimately come from differs between the two designs.

It is staked by the validators who secure Polygon's main network, pays transaction fees there, and is designed so one staked pot can eventually secure multiple Polygon networks at once, earning across them. It is the working capital of the system rather than a share in a company: no revenue entitlement, no ownership, just the token the machinery runs on and the collateral keeping its operators honest.

Ten billion carried over from MATIC's supply, plus modest ongoing issuance, around two percent a year, to fund validators and a community treasury, with the rate subject to governance. So: effectively the old fixed supply with a small managed inflation on top. Not bitcoin-style hard scarcity, not Dogecoin-style open tap; a middle course set by policy rather than immovable code.

No. FSCS protection covers bank deposits to £85,000 and no crypto anywhere. A failed exchange leaves you queueing as an unsecured creditor, rename or no rename. Self-custody puts the risk in your own hands instead, with the small extra Polygon-specific duty of making sure what you are custodying is actually the current token and not its retired predecessor.

Whether activity on its networks grows now the token plumbing is settled, because rails only matter carrying traffic. Watch the zero-knowledge bet maturing: it was expensive and early, and its payoff shows up as usage of the newer networks. And watch the competitive field honestly, since Ethereum scaling has gone from Polygon nearly alone to a dozen well-funded rivals. Being early bought it distribution; keeping it is the current test.
