Web3 infrastructure startup Mysten Labs has announced that the PoS blockchain network called Sui has now released its first testnet, Sui DevNet. It is understood that DevNet can allow validator clients operated by Mysten to send transactions and read requests through the CLI wallet; also a public web browser for browsing DevNet transaction history; and can be a Discord channel for requesting test tokens, which can be used in Pay gas on the test network. Mysten Labs said there will be several improvements to Sui DevNet in the coming weeks, including: 1. Full node support; 2. Gateway service support; 3. Browser wallet support; 4. Event subscription support; 5. Better app developer experience.
