RewardPriceObservation

Documentation for eth_defi.erc_4626.vault_protocol.flying_tulip.historical_context.RewardPriceObservation Python class.

class RewardPriceObservation

Bases: object

One canonical FT/ftUSD price attached to a settled epoch.

The price is deliberately source-chain independent: each settlement uses the Ethereum Curve oracle at the greatest Ethereum block no later than the settlement timestamp. Raw uint256 units are retained in the context cache so replay never depends on float serialisation.

Attributes summary

ethereum_block_number	Ethereum block used for the Curve read.
ethereum_block_timestamp	Unix timestamp of ethereum_block_number.
pool_address	Reviewed Ethereum Curve pool address.
raw_oracle	Raw inverse price_oracle() response.
oracle_updated_at	Curve's last oracle-update Unix timestamp.
raw_ft_price_in_ftusd	Normalised ftUSD-per-FT price, scaled by 1e18.

Methods summary

__init__(ethereum_block_number, ...)

ethereum_block_number: int

ethereum_block_timestamp: int

Unix timestamp of ethereum_block_number.

pool_address: eth_typing.evm.HexAddress

raw_oracle: int

Raw inverse price_oracle() response.

oracle_updated_at: int

Curve’s last oracle-update Unix timestamp.

raw_ft_price_in_ftusd: int

Normalised ftUSD-per-FT price, scaled by 1e18.
