KEY3.id recently announced the support of multi-chain transactions, including major public chains such as Ethereum, BSC, TRON, Polygon, BNB Chain, Solana and more. As the only DID on Ethereum chain to support multi-chain transactions, KEY3.id gained the support and access from wallets such as KuCoin Wallet, CoinHub Wallet, Wallet3 and exchanges such as Yibi to jointly launch the 2023 Lucky Transaction Campaign. The campaign generated mass buzz on Twitter, reaching over 30,000 participants for the draw to transfer 0.2023 USDT to the appointed DIDs of the wallet partners (2023kuwallet.did, coinhub.did, dagen.did) using the partnership wallets. Users now can directly access dApps from different chains using KEY3.id’s .did domain name and Blue-Chip NFT bound DID to make transactions, send and receive tokens as well as NFTs.

DID (Decentralised Identity) is a popular concept in Web3. Traditional identity management systems have long relied on a centralized medium that publishes, holds and controls identifiers and proof of identity. This means that users have no control over personally identifiable information and no way to determine who has access and how much access they have. To address these issues, DID has emerged where it provides solutions for users to create highly readable and easily remembered identities without relying on a centralized organization. According to statistics, the global decentralized identity market is valued at US$181.8 million in 2021 and is expected to reach US$46,457.5 million by 2030, growing at a CAGR of 89.1% during the forecast period.
