add_denormalised_vault_data

Documentation for eth_defi.research.wrangle_vault_prices.add_denormalised_vault_data function.

add_denormalised_vault_data(rows, prices_df, logger=<built-in function print>)

Add denormalised data to the prices DataFrame.

Protocol names and event counts are mapped from the metadata database onto every selected observation. Unknown identifiers remain a hard error because silently exporting partially enriched rows would corrupt downstream reports.

Parameters

• rows (dict[eth_defi.vault.base.VaultSpec, eth_defi.vault.vaultdb.VaultRow]) – Vault metadata keyed by vault specification.

• prices_df (pandas.DataFrame) – Selected price rows containing the canonical id column.

• logger (Callable[[str], None]) – Diagnostic callback accepting one message.

Returns

The input frame with event_count and protocol columns.

Return type

pandas.DataFrame
