Netflix Smart Contract

Similarly to the ERC-1155 contract, or as an extension of that, we can create a Subscription contract. This will work for the user as a funding wallet, where he deposits a certain amount of tokens, he subscribes to multiple services ("Netflix" Smart Contract) and those services will take tokens from the subscription contract according to predefined rules signed by the user.

Admin actions:

Whitelist tokenIDs which are accepted in the subscription contract.

Services actions:

Registers itself as a service Define price and periodicity for their services. One service can offer multiple services. `

User actions:

Deposit/withdraw tokens Subscribe to services by approving/signing the conditions of selected services. If the user signs a transaction in which he says approve@service1@service2@service5 - it means he agrees with the conditions When a user subscribes to a service, the SC has to save the information regarding that service - like the service is allowed to take 5$ worth of tokens from the deposited tokens Unsubscribe from services

Price:

Services might define that the price is in $ worth of X tokens. Like 5$ worth of eGLD. In this case the subscription contract has to integrate safePrice (an existing contract on the chain) which knows the price https://github.com/multiversx/mx-exchange-sc/blob/main/dex/pair/README.md#safe-price-v2 Using the safePrice computation, the service will take X tokens which are worth Y$ at the periodicity approved by the user. (Once per week, once per month, once per day).
