Here are 2 options 1. Tell him to download and set up Cosmostation wallet. It supports Tendermint-based networks such as Cosmos(ATOM) Hub, Iris Hub and Binance Chain (BEP20). After setting it up, tell him to generate for you Binance Chain address where you can send him his BEP20 HARD tokens He can later exchange them for HARD tokens on KAVA network
2. He can also download Trustwallet, which is backed by binance exchange. It also supports Binance Chain tokens and then he sends you the BNB address to send token to - https://trustwallet.com/
