"Login with Ethereum" leverages decentralized identity (DID) by allowing users to sign in to Web2 platforms using their Ethereum wallet (e.g., MetaMask). The wallet acts as a cryptographic proof of identity, eliminating passwords. Websites verify the wallet’s ownership via blockchain signatures, ensuring security and privacy. Users control data sharing, reducing reliance on centralized identity providers (e.g., Google, Facebook). This fosters interoperability between Web2 and Web3 while enhancing user autonomy and reducing data breaches.

Tapswap’s post-drop price crash stemmed from excessive token supply flooding the market after the airdrop, outpacing demand. Early claimants sold tokens en masse to lock in profits, while whales dumped large holdings, creating downward pressure. Poor liquidity on exchanges and lack of utility beyond speculation exacerbated the sell-off.

Identity systems enable portability by using decentralized identifiers (DIDs) and verifiable credentials (VCs) compliant with W3C standards. Credentials are issued with cryptographic proofs that any network can verify, regardless of origin. Cross-chain protocols (e.g., IBC) or interoperability layers (e.g., Hyperledger Aries) translate formats between ecosystems. Users control data sharing via selective disclosure, ensuring credentials remain valid and private across networks.
