SlowMist founder Yu Xian posted on social media that Libra (Libra_protocol) claims to be "the first fair inscription protocol in the world," but it is actually a contract that can mint assets on Arbitrum. It is not open source and each mint requires 0.005 ETH, with each mint fee going to the address starting with 0xe509, and then transferring the funds to the address starting with 0x0c12a, totaling about 231 ETH. Everyone needs to be careful.
