[D-Wallet: Guardian Sign Builds Triple Protection to Reduce the Risk of Single Credential Leakage] D-Wallet's official announcement introduces the multi-layer security mechanism of its Guardian Sign feature. According to the official explanation, holding the private key of the transaction wallet alone cannot extract assets from the multi-signature storage account. When recovering assets through the Guardian Passphrase, the transaction wallet signature is still required for pairing, and funds can only be returned to that wallet address. Additionally, transferring stored assets to another address still requires multi-signature authorization. D-Wallet stated that this design aims to separate the management of daily transactions and asset storage, reducing the security risks to stored assets caused by single credential leakage.
