Approval of token transfer

An explanation for approving spending limits.

Approve Spending Limits

Archi Dollars are minted with DAI as collateral.Using DAI as collateral means that the DAI held by the account that requested Archi Dollar minting is transferred to the Archi Dollar minting contract account.In order for this to be possible, the Archi Dollar minting contract must be able to transfer the user’s DAI on its behalf.

Allowing a user's assets to be transferred on behalf of a user's account is called "Approve Spending Limits."Anything that requires spending limit approval in Cripto Archi Finance services must be approved prior to service request.

Obtaining approval whenever a service is required is inconvenient for users and requires an additional gas fee.Cripto Archi Finance services make you approve spending limits only once by receiving approval for the maximum amount.

It is safe to receive the approval for the spending limit at the maximum value since there is no way to utilize the approved assets for any other purposes in the contract related to Cripto Archi Finance services.
