How do tokens withdraw from rollup to mainnet? @MadFishCommunity

Answer 2: To withdraw tokens from a rollup to the mainnet, the process is still being developed. The first step is to create a withdrawal request on the rollup. This request will need to be signed with the address that owns the tokens and will include the amount of tokens to be withdrawn. Once the request is signed, it will be sent to the mainnet. The mainnet will then validate the request and either approve or reject it. Once approved, the tokens will be transferred from the rollup to the mainnet. Depending on the implementation, it may be necessary to wait for a certain number of confirmations before the tokens are available on the mainnet. Additionally, some rollups may require a fee to be paid for the withdrawal. This fee is usually very small and is used to cover the cost of running the rollup.

I've just talked to our team about this and to give you a more detailed answer, the entire process is not ironed out yet. We'll have to wait a bit and see how it's implemented.
