Ethereum wallet addresses are in hexadecimal (0-9A-F). While the address itself is case-insensitive (e.g. “A” is the same as “a” to the network), the case sensitivity is used as a checksum. It was built as an after-thought to an addressing scheme that lacked basic checksum validation. Since Polygon is a layer 2 network built on Ethereum, the same applies to Polygon.
Most web3 applications do not require the checksum, or automatically correct for it. For example, if I input the following two addresses into PolygonScan, they will both return the EGX contract linked to the token:
Checksum 0x8Db0A6d1b06950b4e81c4F67D1289Fc7B9359c7f
No Checksum 0x8db0a6d1b06950b4e81c4f67d1289fc7b9359c7f
