USYC is available on BNB Chain for eligible users. We outline use cases, integration basics, and eligibility requirements.
Key Summary
USYC — Circle’s tokenized money market fund (TMMF) — is available on BNB Chain. This grants eligible developers and traders access to a yield-bearing TMMF that’s integrated into the DeFi protocols they already use.
USYC on BNB Chain
USYC1, Circle’s tokenized money market fund (TMMF), is live on BNB Chain. That means developers can use USYC as programmable, yield-bearing collateral in the DeFi venues they already rely on — with near-instant settlement in USDC.
BNB Chain is a high-performance blockchain platform with an active builder community and deep DeFi liquidity. That makes it well suited for USYC’s core utility: high-quality, stable collateral accruing predictable yield through token price appreciation. The launch addresses a long-standing gap: many developers and traders have lacked an easy way to access a TMMF that integrates directly into the protocols they use every day.
What you can build with USYC on BNB Chain
Digital asset-ecosystem participants on BNB Chain who successfully onboard with Circle and implement controls to gate access to permissioned wallets can incorporate USYC across a range of use cases:
- Venues can list USYC as a borrow and lend asset, letting lenders earn yield and borrowers potentially pay less net interest
- Perp DEXs can accept USYC as margin collateral, allowing traders to earn yield on posted margin while trading perpetual futures
- Yield Vault platforms can create automated vault strategies that deploy USYC into yield-bearing positions, potentially boosting returns for depositors
Because USYC’s yield accrues through price appreciation, these use cases require no staking, claiming, or reward distribution contracts. They compose cleanly with permissioned AMMs, lending markets, vaults, and structured products. Near real-time onchain redemption into USDC, with no redemption queues, batch processing, or settlement delays under ordinary operating conditions lets liquidation bots, derivatives venues, and automated vaults rely on predictable liquidity for rebalancing and margin calls.
Integration basics on BNB Chain
Integrating USYC on BNB Chain is straightforward for developers who have onboarded with Circle. That’s because USYC integrates with the existing DeFi ecosystem as a standard ERC-20 token (compatible with BNB Chain’s BEP-20 standard), so users can treat it like one in their contracts and UI. Protocols and smart contracts that already use USDC, and are able to enforce allowlisted wallet checks, can use USYC in a similar manner.
Getting started with USYC on BNB Chain
To start using USYC on BNB Chain, first review product details and eligibility requirements, then contact Circle to request access. Once your institution completes onboarding, including KYC/AML, integrate USYC as you would a standard ERC-20 contract. Next, test subscription and redemption flows using the developer quickstart code samples. Subscriptions and redemptions settle in USDC and are available 24/7.
Important eligibility note: shares of the underlying fund and USYC are offered only to non-US Persons, as defined under the Securities Act of 1933, with additional restrictions. Refer to the developer documentation for contract addresses, oracle endpoints, and reference examples.
