Support for DER format signature?

In the caver-js, it shows that all signatures are in (R,S,V) format for sending the transaction. However, does it support DER or ASN1 format? It will be the best because for the company who is using HSM, it can reduce extra effort to rewrite the signing component.

Hi, Thank you for posting first. :slight_smile:
Unfortunately, caver-js does not currently support it.
We will refer to it when selecting future development features. Thanks.
