Spiko
Spiko issues tokenised shares in regulated money-market funds. This integration tracks the Ethereum USTBL token, a share in Spiko’s U.S. Treasury-bill money-market fund. USTBL is a permissioned ERC-20 share, not an ERC-4626 vault.
Spiko’s verified Oracle contract source
implements the Chainlink AggregatorV3Interface and publishes NAV/share.
The adapter reads that NAV together with the USTBL ERC-20 supply to derive an
estimated total fund NAV. The historical reader repeats the same two reads at
each sampled block, beginning at the official Oracle deployment.
Eligibility and dealing
USTBL is not a generic public-deposit product. Spiko’s smart-contract documentation describes permissioned token transfers, issuer-operated minting and a daily redemption workflow. The adapter therefore intentionally exposes no public deposit, redemption or generic flow manager; it is limited to safe read-only discovery, NAV/share and historical analytics.
Fees and curator attribution
Spiko reports a 0.25% annual management fee for its Treasury-bill funds; the published NAV/share is net of this fee. The USTBL contract is attributed to Spiko as an address-scoped, protocol-operated curator because the issuer runs the token permissioning, NAV publishing and redemption servicing.
