Accept USDC on Polygon.
The lowest-fee chain for USDC: $0.01 gas fees and 2-second confirmations. Perfect for high-volume merchants. Customers must already hold USDC. PYMSTR does not convert fiat.
Why Polygon?
USDC on Polygon offers the lowest possible gas fees for stablecoin transactions. Circle issues native USDC directly on Polygon. PYMSTR accepts native USDC only.
Polygon PoS is the cheapest chain PYMSTR supports: gas runs about $0.01 per transaction versus $2-10 on Ethereum mainnet, with finality in roughly 2 seconds. That economics shift matters most for high-volume operators. A sportsbook processing 50,000 deposits a month pays cents in network fees on Polygon where the same flow on Ethereum would cost thousands. The chain is a proof-of-stake sidechain checkpointed to Ethereum, secured by a validator set with over $1B staked, and has years of production history behind it. One caveat that trips up merchants: Polygon historically had two USDC tokens in circulation. Native USDC (issued directly by Circle) and the older USDC.e (a bridged token that originated on Ethereum and was moved over via the Polygon bridge). PYMSTR accepts native USDC only. The native token has largely superseded USDC.e since Circle's 2023 launch, so most holders already have the right one, but it is worth knowing the distinction.

USDC on Polygon: native vs bridged (what PYMSTR accepts)
| Token | What it is | Accepted by PYMSTR | How to tell |
|---|---|---|---|
| Native USDC | Issued directly on Polygon by Circle | Yes | Contract 0x3c49...359 (Circle native); shows as "USDC" in most wallets |
| USDC.e (bridged) | Legacy token bridged from Ethereum | No, not accepted | Often labelled "USDC.e" or "Bridged USDC"; swap to native USDC first |

USDC questions.
No. PYMSTR accepts native USDC only: the token issued directly on Polygon by Circle. USDC.e is the older bridged version (originally minted on Ethereum and moved across the Polygon bridge); it is a different token contract and is not accepted. If a customer holds USDC.e, they should swap it to native USDC before paying. Most wallets and exchanges now default to native USDC, so this rarely comes up in practice.
