Description

KYA (Know Your Asset)

The intent of KYA is to create cryptographically-proven single-source-of-truth for metadata of a specific SRC20 and the asset it represents; token issuers can add and update dozens of parameters and attributes of their project, store them on a website (URL) or IPFS file; this allows investors to have unfettered access to a full history of data change over the life-cycle of the token

NAV (NetAssetValue)

NAV describes the value of the asset which is tokenized by a specific SRC20; it’s a common value in capital markets to describe the value of an asset and is based on underlying reports and assessments about the asset; as NAV represents the value of assets on the Swarm network it is used as the key value to determine the required SWM staking amounts for each SRC20 token
