Fungible token DEX rate

DexRate entity represents rates for fungible token pairs traded on Casper DEXes.

Properties

The DexRate entity has the following properties:

Property	Type	Description
token_contract_package_hash	string	Source fungible token contract package hash
target_token_contract_package_hash	string	Target fungible token contract package hash
amount	float64	Rate amount expressed in the target token
volume	string	The swap volume the rate was calculated on
dex_id	uint16	DEX identifier
transaction_hash	string	Deploy hash associated with this rate
timestamp	string	Transaction timestamp in the ISO 8601 format

volume is normalized using token decimals. For example, if the on-chain amount is 123450000 and token decimals are 6, the normalized value is 123.45.
