According to @cas_abbe, idOS is a decentralized storage protocol that delivers portable identity for the stablecoin economy and is backed by RippleX, Circle, Arbitrum and Starknet. According to @cas_abbe, the protocol enables self-custody of user data, is chain-agnostic to support users and applications across different chains, and emphasizes self-sovereign control. According to @cas_abbe, with the on-chain economy taking off, idOS is an interesting play for traders focused on identity infrastructure linked to stablecoin usage.
