A token can be attached with rights. The token issuer may attach certain right to the tokens. However, since String Funding is reward-based crowdfunding platform, promoter, that is the token issuer, cannot attach investment-related benefits to tokens.
Tokens can be attached with rights that are commonly realised as the payment method. For example, your business can accept the token as a payment method to buy your product and/or service. The token system, that is Blockchain, will not charge you a fee for its own.
Furthermore, the tokens can be attached to different rights according to your business needs. Please contact firstname.lastname@example.org to see how we can help you design your token.
