Token: USDC · NativeFiatTokenV2_2 · 0x3600…0000. Data comes from an unofficial public Blockscout mirror of Arc mainnet (cross-checked against independent onchain analysis) — the official explorer sits behind Circle’s access wall and no public mainnet RPC exists. Numbers may lag or break if the mirror dies; milestones carry their sources. NFA.
