Polygon PoS, chain 137. The native token is POL now, and matic still resolves because half the configs in the world still say it.
Address format
The EVM format, shared by every EVM chain here: 0x and 40 hex digits, any case. An address that fits Polygon PoS fits the other thirteen EVM chains too, and identify says so rather than picking one. The EIP-55 checksum, the one carried in letter case, is verified where there is one: mixed case has to match the hash, and an address in one case throughout passes, since it carries no checksum.
import { getChain } from "@agntn/chains";
const chain = getChain("matic");
chain.assertAddress("0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984"); // returned unchanged
chain.chainId; // "0x89"
chain.caip2; // "eip155:137"
