Is there a simple way to get the KSM address associated with a generic address using polkadot-js library?

Question

I'm trying to get the associated KSM address for a generic address. I was wondering if there was a simple way to do this using polkadot-js library

Answer 1

const { encodeAddress } = polkadotUtilCrypto;
let kusama_prefix = 2;
let kusama_address = encodeAddress(generic_address, kusama_prefix);

For example:

polkadotUtilCrypto.encodeAddress("5DksjtJER6oLDWkWKCWcL3f1swPWeNNFsS9zHxa2rPa7LsH9", 2)

Answer 2

These are not in Polkadot{.js} API, however they are simple to use:

• https://polkadot.subscan.io/tools/ss58_transform
