Published September 15, 2026 Arc Chain Now Live on GoldRush GoldRush now indexes Arc Mainnet, Circle’s Layer-1 blockchain purpose-built for stablecoin finance and global financial markets. Arc uses USDC as its native gas token, offers deterministic sub-second finality, and is designed for payments, tokenized real-world assets, FX, and other institutional onchain applications. Every GoldRush endpoint you already use works on Arc by swapping a single chain identifier - balances, transactions, transfers, token holders, and pricing come back in the same normalized schema as every other supported chain. There’s no new API to learn and nothing downstream to rewrite.

What this unlocks

  • Track USDC, tokenized real-world assets, and other assets on Arc without running your own node or indexer.
  • Query transactions, transfers, token holders, and wallet activity using the same schema as 100+ other chains.
  • Build payment, trading, treasury, and financial applications on top of Arc’s sub-second blockchain data.
Give agents direct access to Arc data through the GoldRush CLI and MCP server. Learn more
