Great team and project. I wish to ask a specific question: Which wallet can i use for keeping gratiz tokens?
Thank you! You can store GRAT tokens in the official Stellar's stellarterm wallet. We connected Gratzio platform through the API to your Stellar's account, so you can use it on Gratzio platform.
Alternatively, you can use any Stellar-compatible wallets. Some of them can be very handy, as you can store multiple currencies.
Look at the Ledger Nano S Wallet - it can store BTC, BCH, BTG, ETH, ETC, LTC, DOGE, ZEC, XRP, DASH, STRAT, KMD, ARK, EXP, UBQ, VTC, VIA, NEO, XST, XLM, HSR, DGB, QTUM, PIVX, POSW, EOS, ERC20...
Here is the full list of wallets:
