Circle, the company that issues the USDC stablecoin, launched its own blockchain yesterday. Arc spent a year as a test network, and Circle said it would build one more than a year before that.

Until now Circle put USDC wherever people already were: on Ethereum, Solana, Base and Tron. Those chains competed for the business while Circle stayed neutral, which suited a company selling a dollar meant to work anywhere. Now it builds the ground its own coin runs on, instead of renting it.

Gas on Arc is paid in USDC, so you'll never need a second token to move the first. Transactions finish in under a second.

Anyone can put an app on Arc without asking, but the machines that confirm the blocks are a known list. BlackRock is on it. So are Visa, Mastercard, the DTCC and Standard Chartered.

More than a hundred applications were live on day one, Aave and Morpho among them, next to Pump.fun and a memecoin launcher Circle has been loud about supporting. DefiLlama counted about $300 million across eight protocols by the afternoon. Wallets can sign with post-quantum keys from the start, which matters to the sort of institution that has to plan twenty years out.

Nikhil Chandhok, who runs product and technology at Circle, says moving activity off Ethereum onto Arc doesn't grow the company's market. So the bet is on business that barely exists yet: software agents paying and hiring each other, local currencies swapping into USDC, and institutional trades that would never go on a fully public ledger.

Tether already runs its own chain, Stripe has Tempo, and a chain called Plasma is going after the same payments money. If you're holding USDC, the company that issues it now also runs a chain underneath it. The same firm picks the validators and writes the rules for freezing a balance.

The Federal Reserve raised its benchmark rate by a quarter point yesterday, to a range of 3.75% to 4%. It's the first increase in three years and the vote was twelve to nothing. Most of the officials wrote down at least one more before the year is out.

A White House spokesman called the decision rather unfortunate.

The part that touches what you own is the bond market. Yields were rising while Kevin Warsh was still taking questions.

The 10-year Treasury yield reached 5.003%, its highest since July 2007, and the two-year Treasury yield went to 4.725%. Lending to the US government for ten years now pays 5%, and that's the competition for everything else you could buy.

Bitcoin, ether and Solana all closed higher anyway.

The crypto bill died in the Senate on Tuesday. On Wednesday the people who actually regulate crypto carried on as though it hadn't.

Michael Selig, who chairs the CFTC, called the vote unfortunate and said his agency will write the rules for crypto markets using powers it already holds. Most of what the bill promised is already moving. He and SEC Chairman Paul Atkins signed a cooperation agreement in March and published a joint list sorting crypto into five buckets, and in August the SEC put its own framework out for comment.

Senator Kirsten Gillibrand and six colleagues put out a statement calling the week "a setback, but not the end of that important work."

A future chair can rewrite agency guidance without asking anyone. Undoing a law would take another act of Congress. So the rules covering what you can buy now depend on who runs two agencies.
