Assets and chains

Polygon

Polygon PoS is an Ethereum-compatible chain, chain id 137, CAIP-2 eip155:137. This index scans it for x402: a USDC transfer whose transaction sender is a registered facilitator wallet. The token is Circle's 6-decimal native USDC on Polygon, not a guessed wrapped asset.

Explanation

Polygon is one of the EVM chains in the facilitator registry, alongside Base and Arc. The same Transfer-log rule applies. The index does not infer a protocol from the chain alone. A USDC payment on Polygon that does not come from a registered facilitator wallet is outside the series.

Chain rankings and the x402 protocol total are different groupings. Polygon's number is already inside x402 when the sender rule matches. The chain page is the place to see the Polygon slice.
