Apologies for the delay. You’re right, the supply of Smart Tokens is dynamic, however, prices still rise with increasing supply, and fall with decreasing supply, because the algorithm holds the balance token at a constant ratio (the CRR) to the Smart Token’s total supply. In use cases where a fixed supply token is needed, you can create a Token Relay. Token Relays are new Smart Tokens with two or more ERC20 tokens (smart or standard) in their reserve, totaling 100% CRR between them. This allows you to keep a fixed supply (standard token) and yet still become backwards compatible to the Bancor protocol, providing continuous and automated conversion between your fixed supply token and all other tokens in the liquidity network. For more information on how Token Relays (formerly known as Token Changers) work, please see our whitepaper: We’re really excited to be able to accomodate existing ERC20 tokens, and fixed supply tokens such as you describe (membership models, agricultural yields, etc.) within the Bancor liquidity network using Token Relays.
Thanks for a great question, and your support!
