You can send through https://wallet.wax.io
You can add your MYTH tokens to your wax wallet as a custom Token

Manage -> Add Custom Token -> fill in the following values:
Token Symbol: MYTH
Decimal Places: 4
Token Contract: mammothtoken
Token Name: MYTH
Token Image: QmZqe83K5vv9F1KEw46GiMLmo5EtZ4HbZdKgrmd3xNLQrV

Once that is done you can send it by clicking send and adding the target address.

(This is currently a temporary manual way as we are in discussions with Neftyblocks to be able to list our NFTS for MYTH tokens)
