Masa Finance has launched the first soulbound identity protocol for the Ethereum mainnet, according to a Jan. 17 press release shared with Cointelegraph. The protocol will allow for standardized soulbound tokens to be minted on Ethereum for Know Your Customer verification, credit scores and other use cases.

Soulbound tokens are tokens that cannot be transferred from one wallet to another. The concept was popularized via a blog post from Vitalik Buterin, who argued that these tokens could be used to signify governance rights for decentralized finance (DeFi) protocols or to prove that a person has attended an event.
