In order to claim proceeds assigned to your Neumarks you need to go through the registration & verification process using the wallet on which you store your NEU tokens. Only after a successful identity verification process we are allowed to payout the dividends.
If you already have a verified account on Neufund you can transfer your NEU tokens to the wallet assigned to the account and claim the proceeds afterwards.
Proceeds are assigned to your NEU tokens and can be claimed after the proceeds have been already distributed. Those claims are locked on ETO smart contracts.
