What is USYC?
Circle USYC (USYC) is a fiat-backed US dollar stablecoin issued by Circle (formerly Hashnote). It has about $2.40B in circulation, ranking #9 among the stablecoins CoinScoop tracks, and runs on 2 blockchains.
USYC is a yield-bearing fund token rather than a payment stablecoin. Its price rises above $1 as interest accrues. Circle acquired its issuer, Hashnote, in 2025.
In the issuer's words: USYC is a tokenized money market fund backed by U.S. Treasury bills, designed by Hashnote Labs (now part of Circle) to generate yield within the token itself for use as collateral in crypto markets.
USYC supply history
USYC supply fell 8.6% over the past 30 days, to $2.40B. Its peak was $2.77B in June 2026, and supply is 13% below that high.
Is USYC holding its peg?
USYC passes yield through by raising its token price, so a value above 1.00 is by design rather than a broken peg.
Where USYC lives: supply by blockchain
Supply is concentrated: BSC holds 98% of all USYC. Moving it to another chain means bridging, or a mint and redeem through the issuer.
How USYC is backed
USYC is backed by a tokenised money market fund holding short-term US Treasuries and reverse repos.
Minting and redemption: USYC is minted when users deposit USDC into USYC fund, which then invests in short-term U.S. Treasury bills to create the yield-bearing token, and it can be redeemed by converting it back to USDC at a 1:1 ratio through Circle's system.
USYC risks
Your claim is on the issuer and the banks or funds holding its reserves. A failure or freeze there can break the peg, as USDC briefly did in March 2023.
Fiat-backed issuers can usually freeze tokens at specific addresses, for example to comply with sanctions or court orders.
Copies of a stablecoin moved by third-party bridges depend on those bridges. Prefer the issuer's native contract on each chain.
Rules such as the US GENIUS Act and the EU's MiCA can restrict which stablecoins exchanges list in a given country.
