eurSPKCC, issued by Spiko Finance (Spiko SAS), is a tokenized money market fund share that tracks Digital Assets Cash & Carry Fund - Euro Share Class, recorded onchain via a fully tokenized UCITS share registry [S1][S2].

The token gives a tokenholder economic exposure to Digital Assets Cash & Carry Fund - Euro Share Class (eurSPKCC), a regulated UCITS fund investing in short-term government Treasury Bills. The fund is accumulating and total-return, so interest accrues daily into the share NAV rather than rebasing token balances, and value accretes per share [S2]. The tokenholder bears a management fee of 0.25 percent per year, deducted daily on a prorated basis, with no entry, exit, transaction, or account-holding fees [S2][S1].

Spiko Finance is a simplified joint-stock company registered in Paris, France, and is a MiFID-authorized investment firm regulated by the French ACPR, while the funds are AMF-supervised money market UCITS managed by Twenty First Capital with CACEIS Bank as depositary [S3][S1][S2]. Each token legally represents a regulated UCITS fund share, not e-money or a stablecoin [S2]. Onboarding requires KYC and AML verification, and only allowlisted addresses may hold or receive tokens under a configurable compliance policy [S4][S5]. Daily liquidity is contractually guaranteed, with deposits and withdrawals processed daily in fiat or stablecoins; client cash is held by CACEIS, never by Spiko [S1][S2].

Tokens are ERC-20 based, with ERC-1363, ERC-2612, and ERC-2771 extensions, issued across Ethereum, Polygon, Arbitrum, Base, Starknet, and Stellar [S5][S6][S7]. A daily-operator role mints tokens to allowlisted addresses; redemptions are batched daily and tokens burned when transfers initiate [S5]. NAV is calculated daily by CACEIS, submitted to the AMF, and published onchain via a Chainlink oracle, while EURCV and USDCV stablecoins provide settlement [S5][S4][S8][S9].

# APY methodology

## 1. Overview

APY measures the annualized yield accrued by holding a yield-bearing token. On-chain state is standardized into a yield index that captures yield accrual regardless of mechanism — whether the token grows in value against its underlying (e.g. ERC-4626 vaults) or rebases in quantity (e.g. stETH). A 7-day trailing window is used to annualize the growth of this index over time.

## 2. Data sources

- **EVM chain state reads**: `convertToAssets` functions from ERC-4626 contracts, `getReserveNormalizedIncome` functions from Aave contracts, `pricePerShare` functions from ERC-7540 contracts, and NAV feeds from oracle contracts, covering EVM-compatible chains (Ethereum, Arbitrum, Base, Polygon, Optimism, and others).
- **Asset metadata**: Token addresses and decimal precision.
- **External data**: End-of-day price feeds.

## 3. Step-by-step calculation

### Component A: Yield index extraction

- **Purpose**: Retrieve daily cumulative yield indices from on-chain sources.
- **Logic**: Daily yield indices are aggregated from contract state reads across supported chains. These indices represent the current exchange rate or internal value of a yield-bearing token in terms of its underlying asset. On EVM-compatible chains, data is retrieved from standard interfaces including ERC-4626 vaults, lending market reserve indices, and specialized share-price functions. Amounts are normalized by decimal precision.
- **Key fields**: `yield_index_normalized` (cumulative yield index), `token_address` (asset contract), `timestamp` (record time)

### Component B: Trailing yield annualization

- **Purpose**: Compute the annualized growth rate of the yield index.
- **Logic**: A 7-day trailing window is applied by comparing the current yield index to the index recorded seven days prior. The ratio of change between these two points is annualized to produce the APY.
- **Key fields**: `asset_apy` (calculated annualized yield)

### Component C: Cross-chain deduplication and final aggregation

- **Purpose**: Consolidate yield data into a single daily value per asset.
- **Logic**: Data is combined across all supported chains. For assets deployed on multiple networks, a representative APY is selected by identifying the value closest to the cross-chain median for that specific timestamp. This process ensures that deployment-specific spikes or stale data from less active chains are mitigated. The resulting value is mapped to the global asset identifier and recorded as the daily APY.
- **Key fields**: `asset_id` (unique asset identifier), `asset_apy` (final annualized yield)
