About W5 wallet version
As the TON blockchain has developed, new wallet versions have emerged to meet the needs of the ecosystem, with W5 being the latest version.
W5 supports transactions with up to 255 operations* simultaneously. For example, you can purchase several desired NFTs or list some items for sale in one transaction. Previous wallet versions only allowed a maximum of four nested operations.
W5 will support the account recovery option and two-factor authentication (2FA) quite soon.
You need to enable the corresponding setting in your wallet app to switch to W5**.
*сurrently, up to 100 actions are available when sending transactions, but this number will increase in the future.
**make sure your wallet app fully supports the W5 version. An example of such a wallet is the Tonkeeper mobile app for iOS and Android (you should update the app to the latest version).
