Why index a chain that already has fast RPC?
Because RPC answers one question at a time. Arc produces a block roughly every half second, so a question like "every USDC transfer above a threshold last month, grouped by counterparty" is tens of thousands of RPC calls and a pile of decoding. In SQL it is one query.
What about the USDC decimals trap?
It is handled at index time. USDC on Arc behaves as 18-decimal native gas and as a 6-decimal ERC-20, a difference of 10^12 that silently corrupts naive pipelines. The warehouse stores raw integers and records which convention each column follows, so the ambiguity never reaches your query.
How is the Arc indexer priced and provisioned?
It is not on sale yet - the Arc indexer is in build. Tell us on Telegram which tables you need and roughly how you will query them, and you go to the front of the queue when it opens. Billing, when it opens, is the same as everything else here: crypto-only, monthly and prepaid.
