USDC on Arc: the stablecoin-native model

Arc uses USDC as its native gas token. USDC is represented on Arc as both a native token and an ERC-20 token, with one shared balance:
Allium serves the 18-decimal native form only, under the null address 0x0000000000000000000000000000000000000000. Both system addresses are canonicalised onto that address at ingestion, so USDC is complete there.
  • Find USDC in native_token_transfers, fungible_* and stablecoins under 0x0000000000000000000000000000000000000000, at 18 decimals.
  • erc20_token_transfers excludes both system addresses — their Transfer logs are native movement, already served as native transfers.
  • Arc has no wrapped-native (WETH-style) contract.
