Does anyone have any updates on ERC-1337 (subscription model)? I don't see how progress can be made since they want to support ERC20, and ERC20 requires manual approval on the user's end for every transaction that a service provider wants to make
The end user could hypothetically approve the maximum amount (2^256), but that enables the possibility of the service provider to just take all their coins.
Wouldn’t an alternative coin standard need to be invented? The new approval function would take in a start date and a period length (monthly, yearly, etc.), and the provider could only charge once within the start date and period length (and then the start date would be updated to the latest timestamp).
Or am I missing something?
Hello everyone.
I have a question regarding EIP1655 and creating the interfaceID of an interface
contract via the XOR of all its function selectors.
https://eips.ethereum.org/EIPS/eip-165
Do we have to include selectors from inherited interface in the XOR calculation?
Or just the selectors from the interface itself?
As an example
interface A {
function a() external;
}
interface B is A {
function b() external;
function c() external;
}
Is the interfaceId of B
calculated as:
(1) - a.selector ^ b.selector ^ c.selector
?
or (2) - b.selector ^ c.selector
?
In Solidity, type(B).interfaceId
returns the result of (2) but I would like to make sure I understood the EIP properly.

is the zero address.from_address
is the zero address. It mentioned the event documentation, but I don't see where is it.

That validates permission for a given address in an ecosystem.
