Hi @kizumo, as a delegator to MAP Rewarder, you have received an airdrop of new MAPR tokens. Please read this new post, MAP Rewarder: Launch of MAPR Token - Airdrop to Delegators, that explains further on how the MAPR token has been designed and how future rewards will be distributed.
Enjoy the airdrop! I know it looks modest, but the tokens are actually worth something! (msg 28 July)
