Spiko

Spiko issues tokenised shares in regulated money-market funds. This integration tracks the Ethereum USTBL token, a USD share in Spiko’s U.S. Treasury-bill money-market fund, and Arbitrum EUTBL, an EUR share in Spiko’s Eurozone Treasury-bill money-market fund. Both are permissioned ERC-20 shares, not ERC-4626 vaults.

Spiko’s verified Oracle contract source implements the Chainlink AggregatorV3Interface and publishes NAV/share. The adapter reads that NAV together with ERC-20 supply to derive an estimated total fund NAV. USTBL is already USD-denominated. EUTBL’s issuer NAV is in EUR, so the adapter combines it with Chainlink’s Arbitrum EUR/USD feed before exporting USD-normalised share price and TVL; the source EUR denomination remains present in metadata and the top-vault export’s source_denomination field. The historical reader repeats these reads at each sampled block, beginning at the official Oracle deployment.

Eligibility and dealing

Spiko products are not generic public-deposit products. 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 and EUTBL contracts are attributed to Spiko as address-scoped, protocol-operated curator products because the issuer runs the token permissioning, NAV publishing and redemption servicing.
