USDC is a digital dollar. It is a token that is designed to always be worth one US dollar, issued by a US company called Circle and backed by cash and short-term US Treasuries held in reserve. You can send it anywhere in seconds, and you can redeem it one-for-one for a real dollar. Tokenized real-world assets settle in USDC because it moves on the same blockchain as the asset itself, holds a steady value, and lets payments happen automatically - none of which a bank wire can do.

What exactly is USDC?

USDC is a stablecoin - a token built to track the value of a currency, in this case the US dollar. It is not a speculative asset like Bitcoin. One USDC is meant to equal one dollar, today and next year, so it behaves like cash that happens to live on a blockchain.

It is issued by Circle, a regulated US financial company. When someone deposits a dollar with Circle, Circle issues one USDC; when someone redeems a USDC, Circle takes it out of circulation and returns a dollar. That one-to-one issue-and-redeem is what keeps the price anchored to a dollar.

How does it stay worth a dollar?

Every USDC in circulation is meant to be backed by an equal value of safe reserves - mostly cash and short-term US Treasury bills. Because the backing is real and liquid, holders can always redeem for a dollar, and that ability keeps the market price at a dollar too.

You do not have to take this on faith. Circle publishes monthly reserve reports, and the reserves are confirmed by an independent accounting firm through an attestation - a formal check that the money is really there. This is the stablecoin version of proof of reserves, and it is the first thing to look for in any stablecoin.

Why do RWAs settle in USDC?

Three reasons, and each one is practical.

• It lives where the asset lives. A tokenized asset is on a blockchain, and so is USDC. Paying for the asset and holding the asset happen on the same rails, so settlement is near-instant instead of waiting days for a wire.
• It holds its value. You would not want to buy a Treasury bill with a currency that could drop 10% overnight. A stablecoin stays put, so the price you agree is the price you pay.
• It can be paid out by code. When a deal distributes rent or interest, a smart contract can send each holder their share in USDC automatically, pro rata, with no manual bank transfers.

Most USDC moves as an ERC-20 token - the common standard that wallets and apps already understand - so it slots into the same tools you use for everything else.

Is USDC the same as dollars in a bank?

Not quite, and the difference is worth knowing. A bank deposit is insured by the FDIC up to a limit; USDC is not a bank deposit and does not carry FDIC insurance. What backs USDC is Circle's reserves and your right of redemption, not deposit insurance.

In practice USDC has held its one-dollar value well, with one notable wobble in March 2023 when part of its reserves sat at a bank that failed; it recovered its peg within days once those funds were confirmed safe. The lesson is not that stablecoins are fragile, but that the quality of the reserves and the transparency around them is what matters - which is exactly what you can check before you hold any.
