class SpikoProduct

Bases: object

One reviewed Spiko permissioned fund-share deployment.

Parameters

• chain_id – EVM chain hosting the token and issuer NAV oracle.

• token – ERC-20 proxy address representing shares in the fund.

• price_oracle – Spiko Oracle proxy implementing the Chainlink AggregatorV3 view interface for the fund’s NAV/share.

• first_seen_at_block – Token proxy deployment block.

• first_seen_at – Token proxy deployment timestamp as a naive UTC datetime.

• oracle_first_seen_at_block – First block containing the product’s official NAV oracle.

• symbol – Onchain ERC-20 symbol.

• denomination_symbol – Currency in which Spiko publishes NAV/share.

• description – Public investment-strategy description.

• short_description – Concise public product description.

• management_fee – Published annual management fee as a fraction.

• product_url – Official Spiko product page.

property nav_source: str

Return the stable identifier for the issuer NAV source.

Returns

Product-specific Chainlink-compatible oracle source label.
