TON (The Open Network) has introduced a new smart wallet standard called W5, which enables gasless transactions on the TON blockchain. This upgrade to the layer-1 blockchain's existing wallet smart contract allows users to use Tether (USDT) for gas fees when transferring USDT and Notcoin (NOT) for gas fees when transferring Notcoin. The W5 smart wallet is live in Tonkeeper and will soon roll out to TON Space and MyTonWallet
