Superstate

Subscribe USDC into Superstate’s USTB or USCC fund on Ethereum and request off-chain redemption.

Superstate is a real-world-asset issuer with two funds on yield.xyz: USTB, an Invesco short-duration government securities fund, and USCC, a Bitwise crypto carry fund. Both share one on-chain token contract per fund with a built-in allowlist, a 100,000 USDC minimum, and a one-day redemption cooldown.

List the Superstate yields enabled for your project with GET /v1/yields filtered by providers=superstate. Both yield IDs are static: ethereum-usdc-superstate-ustb-vault and ethereum-usdc-superstate-uscc-vault.

Both funds set kycRequired: true, kycMode: external_redirect, and defaultPolicy: deny on eligibility: only a fixed allow-list of countries can pass, enforced by IP at action creation as well as by the on-chain allowlist (usPersonAllowed: true for both). The specific country list and investor-tier requirements are exposed in each yield’s kyc.eligibility metadata rather than reproduced here; USTB accepts either Accredited Investor or Qualified Purchaser status, while USCC requires Qualified Purchaser status specifically. See RWA KYC for the generic verification flow, which also covers the KYB subject type both funds require alongside individual KYC.

Entering

The enter argument is amount, in USDC, with a 100,000 USDC minimum (minimumStake) enforced both in the module and on-chain. Entering calls the fund token’s subscribe function directly in a single transaction. USCC orders are priced at Superstate’s 5:00pm ET market-day cutoff rather than continuously; the yield’s investmentSchedule exposes the cutoff and settlement timing. The yield’s status.enter is false while the fund token contract is paused.

Exiting

Exiting is a request, not an instant payout: the exit argument amount, in the position token, calls the fund token’s offchainRedeem function, which burns the position token on-chain and queues an off-chain payout. There is no separate claim action tracked by yield.xyz; Superstate settles the redemption off-platform on the fund’s advertised timeline, reflected as the yield’s one-day cooldownPeriod. The yield’s status.exit is false while the fund token contract is paused.

Rewards and position

Yield accrues in the position token’s net asset value relative to USDC; reward claiming is automatic. Which fee types you can configure on this yield is listed in mechanics.possibleFeeTakingMechanisms; see Monetization.

Both yields expose investmentSchedule metadata for their processing windows.
