adding restrictions to token movements

Question

I am about to create a white listable currency in Ethereum, that is a fiat backed Stablecoin, and I wanted to find out if i can do it in multichain. The main requirement is that for any set month, each user address has an inward allowance that cannot be exceeded - that allowance can can be updated at any time by admin. So a user can have money sent to his address, but the transaction total must not exceed that allowance total for the month. How would that be done easily in Multichain?

Answer 1

I'm afraid this kind of transaction rule can't be implemented in a simple way in MultiChain. But there is a way to make it possible: to have incoming funds to an address not be immediately spendable, and for the recipient to have to conduct a second transaction (which you could automate in the application) to make the funds spendable, by using up a "receiving limit" which is stored in some inline metadata output which the user has control over. The spendability limits could be enforced on-chain with a transaction filter.

The ability to change these limits would be tricky right now, but a new smart filter related feature we are currently implementing, and which will be available in the next protocol upgrade, will make it easy.
