Arc raised $222M today from backers including BlackRock, Apollo, and ICE - at a reported $3B valuation. The thesis is clear: autonomous finance needs infrastructure built for AI agents from the ground up. One of Arc’s biggest design decisions is making USDC the gas token. For AI agents, predictable costs matter more than speculation. Agents paying for compute, executing trades, routing capital, or settling hundreds of transactions a day cannot rely on volatile gas economics. Dollar-denominated fees create stable operating costs and make autonomous financial systems far more practical at scale. @goldrushdev supports Arc from day one. Our APIs already cover the full stack: • wallet balances • token transfers • DEX activity • historical transactions • cross-chain indexing across 100+ chains Building with Claude or Codex? Our MCP server plugs in natively, giving agents access to 27+ blockchain data tools out of the box at @goldrushdev(Covalent)
