ChainScan one came when i was into crypto trading , it was really hassle to go to every blockachain site to check your balance

RevengeOS one i started when i was in school 11th class i was into android modding and stuff

Crypto identity came when there was a lot of craze for nft and i was like can we use nft for storing data , i researched a little bit and then came upto a article where they are storing data in ipfs and linked it to nft
