Is WETH safe on Polygon? The wrapped ether map's mintable leg
WETH on Polygon is the wrapped-ETH map's mintable leg — ~1.93 million holders behind a live mint grading B (75) on our September 27, 2026 read, the fourth distinct contract shape for the same asset.
Wrapped Ether on Polygon grades B (75). One bad flag: the contract can mint new supply. Everything else clean: freeze disabled, verified source, trust-listed, liquidity workable, creator under 0.01%. Behind it: ~1.93M holders, 1,687 days live — nearly five years — ~$4.3M of daily volume on ~$241M of cap.
It completes the series' four-shape WETH map: ethereum's native (A-100), arbitrum's proxy (B-80), base's locked copy (A-100) — and now polygon's mintable receipt (B-75). The page's subject is why the same asset's safest and most-powered legs sit two letters apart.
The mint on a wrapped asset
The bad flag needs its exact framing: on a bridged WETH the mint isn't a rug lever — it's the mechanism. Polygon's WETH is a bridged receipt: canonical ether gets locked on ethereum's side, and this contract mints the corresponding claim on the polygon side. "Can mint" is what a bridge deployment does; the checklist flags it because capability is capability, and the same function that reflects a deposit could fabricate one.
That framing is why the letter is B-75 and not lower: a single live verb on a verified, trust-listed, freeze-disabled contract is the checklist's price for "receipt machinery," and on a bridged asset it's the price the mechanism carries by design.
1,687 days of the mint working
The age column ties this page to the batch's other senior deployment — arbitrum-WETH, also 1,687 days — and marks it as the early-L2 era: Polygon's bridged ether shipped when the chain was the scaling answer, and this contract has been minting receipts against deposits for nearly five years.
The conduct record over that span is the flag's counterweight: thousands of days of the mint exercised publicly against locked collateral, no snapshot-flagged emission event. The standing discipline applies verbatim — the mint is live today exactly as it was on day one; the 1,687 days are evidence about use, not proof about architecture.
~1.93M wallets of bridged ether
The holder base is the second-largest of any WETH leg — behind only base's ~5.27M and ahead of ethereum's ~3.67M and arbitrum's ~426K — because Polygon's retail-era chain accumulated bridged-ether balances at scale during its 2021-22 throughput peak. ~$241M of cap across ~1.93M wallets implies a ~$125 mean: a dust-weighted distribution of users who received or held small WETH positions.
For the flag set that's the relevant shape: the mint's theoretical blast radius is a crowd of small balances — the power is real and the per-wallet exposure is small. As on every bridged asset, the constituency least able to check the mint is the one the count is made of.
A workable pool for a wrapped rail
~$11M of tracked depth against ~$241M of cap is ~4.5% coverage — inside the checklist's "workable" band rather than its thin warn, because the measure is calibrated to the token's own size. ~$4.3M of daily volume (~0.39x turnover) is the working rhythm of a bridged utility asset: the venue exists to move ether exposure on-chain, not to carry the asset's whole value.
The structural note the page adds: on a bridged WETH the systemic exit is the bridge itself — unwrapping back to canonical ether on ethereum — not the DEX pool. The ~$11M venue serves the retail end; size travels the redemption path, as it does on every wrapped asset this series has graded.
The supply figures that agree
~88,903 circulating of ~88,889 total — a >100% micro-seam of the kind this series keeps meeting on bridged assets (polygon-DAI, base-WBTC, arbitrum-WETH all print the same direction). On a mintable receipt the small overshoot is bridge-accounting residue — minted-not-yet-reconciled units in the correspondence — rather than evidence of a runaway mint. The seam matters because the mint is live: on this contract, supply arithmetic is the thing the flag is about, so the page prints the pair to the unit.
Scale check: ~89K WETH at ~$2.7K reconciles to the ~$241M cap — the ledger's figures tell one coherent story about how much ether sits in Polygon's wrapper.
The fourth shape on the WETH map
The completed map is the page's context payload: ethereum A-100 (the native, inert by definition), base A-100 (the modern locked receipt), arbitrum B-80 (the early-era proxy, unexploited at 1,687 days), polygon B-75 (the early-era mint, exercised as designed at 1,687 days). Four contract shapes, three letters, one asset.
The ordering is the checklist's logic made visible: a locked copy beats an unexercised proxy, and an unexercised proxy beats a working mint — not because any of them has failed, but because the capability ladder runs inert > repointable > writable. Polygon's leg sits at the map's powered end because its bridge chose verbs over immutability — the correct choice for a receipt, and the reason the flag exists.
What the mint threatens on ether specifically
One paragraph of mechanism the page owes: on a wrapped ether receipt, a rogue mint wouldn't just dilute — it would break the claim correspondence that makes the token worth anything. Every unit in circulation is supposed to pair with locked ETH on the other side; a fabricated mint prints claims with no collateral, which is the failure mode the flag encodes. The 1,687-day record is the evidence that the mint has only ever printed against deposits — which is the only way a receipt's mint is allowed to work.
Same age, different flag
A comparison the batch makes possible: polygon-WETH and arbitrum-WETH are twins on age (1,687 days each) separated by mechanism — one keeps its upgrade path, the other keeps its mint. The checklist prices them B-80 and B-75 respectively, five points apart — the price difference between "the code can be replaced" and "the supply can be expanded." On the same asset, same era, same issuer-free architecture, the whole difference is which verb the contract kept.
Why ether keeps needing new receipts
A framing paragraph for the map's oddity: WETH has more legs than almost any asset in the ledger because every chain needs its own wrapped ether — the bridge can only mint a claim on the chain it lands on, so each L2's "ETH" is a different contract with a different custody path. That's why the map exists at all: ethereum's native needs no bridge (A-100), and every copy inherits its bridge's architecture. The holder's question "is my WETH safe" is always really "which chain's WETH, and which bridge's machinery" — and the checklist answers at the contract level, which is exactly where the difference lives.
Holding it, honestly
If you hold WETH on Polygon you hold the wrapped-ETH map's mintable leg: ~1.93M wallets, a working ~$11M venue, and a mint that's been doing its documented job for 1,687 days. The B-75 is the checklist pricing the verb honestly; the record underneath is what a bridged receipt's live mint looks like when it's been behaving the whole time.
Frequently asked
Is WETH safe on Polygon?
As of September 27, 2026 it grades B (75) — one bad flag (live mint, the bridge mechanism) on an otherwise clean surface.
Why can Polygon WETH be minted?
It's a bridged receipt — the mint is how locked ethereum ETH gets its Polygon-side claim printed. 1,687 days exercised as designed.
How much liquidity does Polygon WETH have?
~$11M tracked on ~$241M cap (~4.5%) — workable; the systemic exit is the bridge back to ethereum, not the pool.
Is Polygon WETH the same as Arbitrum WETH?
Same era (both 1,687 days) but different verbs: Arbitrum keeps a proxy (B-80), Polygon keeps a mint (B-75).
What would a rogue mint do on WETH?
Print claims with no locked ETH behind them — break the collateral correspondence. The flag is that capability, unexercised in the record.
