restrictions param

Question

Must the restrictions param of crate method be '{}' when type = txfilter/streamfilter？

Answer 1

For stream filters, restrictions must be the empty object: {}

For transaction filters, you can pass one or more asset/stream names/refs in order to only apply the filter to transactions which make reference to one of those assets or streams, e.g.:

{"for":["asset1","stream1","stream2"]}
