A place for talking about the Ethereum Virtual Machine on Farcaster.

Is ERC-5192 the current standard to use for SBTs? Haven't heard much on its use at all and wanted to double check

https://persistence.wtf / https://nouns.build

I am not sure since I didn't read the erc5192 but I am always create SBTs overriding the _beforeTokenTransfer function.

The idea is allow only minting and burning requiring:

from == address(0) || to == address(0)

This way, all transfers will fail.

(I am going to read the ERC5192 now)

after read the erc5192,

erc5192 is implementing the locked logic using a boolean and a modifier and it adds a way to allow others (devs, marketplaces,..) to know that the token is an SBT.

Maybe @timdaub.eth has a better answer. He wrote the eip5192.

(ok, Tim, now, I am scared, this cannot be a coincidence 😅)

All transfers will fail except minting and burning*
