• KiroboService from @kiroboio/fct-service

• NFTUpdateDto, nftDto from ./types/nfts.dto

Functions

itemId(item: nftDto | NFTUpdateDto, networkName: string)

This function generates a unique id for the given NFT item in the format of {token_address}#{token_id}@{networkName}.

unwatchNFTs()

This function removes all listeners for the NFT service and resets the NFT state.
