This is alpha, WorldApp login should be in staging mode

Currently, we support Ethereum mainnet only (will support more chain soon**)**

PoPwallet

With worldapp authentication, an on-chain user can "link" one address per chain in the PoPwallet to authenticate that the linked address is the only one in that chain.

In the existing crypto ecosystem, there is an invisible war going on between multi-accounters and foundations. There are a lot of battles going on to stop sybil attacks. For example, Paraswap has effectively defended against it by using wallet tracing. (ref.)

Transaction map of metasleuth

In response, multi-accounters are referring to tools like metasleuth to bypass it, and even checking transaction paths to hide the origin of tokens by sending Ethereum from different CEX. As this battle continues, the labor and computing resource drain of increasingly complex transactions will increase. For now, the best way to prevent it is not captcha, not a bunch of web-2 authentication, but Worldapp.

Worldcoin ORB

A worldapp is an unique, biometrically authenticated proof of personhood that can't be easily replicated.

PoPwallet dapp

We can simplify authentication between dapps and on-chain users. Users don't need to authenticate through the app every time they access another dapp, and the dapp only needs to verify that the address is authenticated using our API without any transactions. It's incredibly simple & fast protocol for providers and users alike.

Users can assign an address to each chainid permanently**.** (with a wallet connection, of course!!) This should be linked very carefully and in most cases irreversibly (unlinking it for reasons like lost mnemonics would be a huge effort).

In other words, PoPwallet is anti-multi-wallet protocol!
