find_allowed_assets
function find_allowed_assets(sender_blockchain_rid: byte_array, sender_id: byte_array, recipient_id: byte_array): map<byte_array, big_integer>?(source)
Finds all assets that a certain sender on a certain chain can send to the specified account ID to allow its registration.
This function can return that no asset is allowed. This means:
no rule allows account registration for the specified combination of parameters; or
a rule that allows this specific registration is found, but the asset that it requires is not yet registered on this chain.
Return
a map<asset_id: byte_array, amount: big_integer> or null if there's no rule allowing this specific account registration at this moment.
Parameters
sender_blockchain_rid
the RID of the blockchain where the transfer will originate. This blockchain's RID for on-chain transfers.
sender_id
the ID of the sender account
recipient_id
