About Circle USYC (USYC)
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 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

Peg stability history
Circle USYC (USYC) is designed to trade at exactly 1.00 USD, with its peg defended through direct redeemability against off-chain reserves. Spot price currently sits at $1.1195, a +11.947% deviation from the target — well inside the stability band typical for reserve-backed dollar tokens.
How reserve-backed stablecoins defend their peg
Fiat-backed stablecoins maintain their peg through arbitrage: any time the secondary-market price drifts above $1.00, authorised participants mint new tokens by depositing dollars and sell them into the market; any time it drifts below, they buy on the open market and redeem 1:1 for dollars. The peg therefore depends entirely on (a) the reserves actually existing, (b) the issuer honouring redemption requests promptly, and (c) the issuer remaining solvent and unfrozen.
Practical implications for holders
- Counterparty risk is concentrated in the issuer and its banking partners — a banking failure (as in the March 2023 USDC / SVB episode) can cause short-term depegs even when the underlying reserves are sound.
- Reserve attestations are not full audits. Always read the firm name, scope, and date of the latest attestation report before treating the peg as risk-free.
- Redemption rights typically apply only to verified institutional partners, not to retail holders. Retail exposure is exited via secondary markets, where liquidity matters most during stress periods.
- Regulatory action against the issuer (NYDFS orders, OFAC freezes, court-ordered blacklists) can immediately impair specific addresses or even the entire token.
- Mantapex tracks peg deviation in real time from DeFiLlama price feeds, but for high-value holdings cross-check directly on at least one independent venue (CoinGecko, the issuer's own dashboard, or an on-chain DEX).
Peg-stability commentary is based on the mechanism class (reserve-backed) and is provided for educational purposes only — it is not financial advice. Past peg stability is not a guarantee of future performance, and even the highest-quality stablecoins have historically traded outside their target band during banking, regulatory, or liquidity stress.
Contract addresses
Circle USYC (USYC) is deployed as a token contract on 1 blockchain network below. Always verify the contract address you're interacting with on the relevant block explorer before sending funds — phishing tokens reusing well-known stablecoin tickers are common, especially on newer chains.
| Chain | Contract address | Verify |
|---|---|---|
| Ethereum | 0x136471a34f6ef19fe571effc1ca711fdb8e49f2b | Explorer |
Contract addresses are sourced from DeFiLlama's stablecoin profile. Some chains (Tron, Solana, Aptos, Sui) use non-EVM address formats. The "Explorer" link opens the official block explorer for the given chain; we do not link out to third-party explorers that may show altered data.
