Sisters, I just finished reading @Hertzflow_xyz’s latest Pools & Vaults guide. When depositing test USDT for the first time, you need to Approve first, then separately click Deposit. Many people think they’re done once they see “Approval successful,” but that’s not the case—I care deeply about who exactly received this permission and how much was granted. Connecting simply links your wallet; Approving lets a specific contract spend a certain amount of USDT; only Deposit actually moves your funds. Clicking through the Approve popup doesn’t move anything. The official documentation labels the Router as “Token approval management,” yet publicly available info doesn’t directly disclose the specific spender address or clarify whether the default allowance is exact or unlimited. Before signing, always check the token, spender, and amount. After exiting, double-check whether the allowance still exists. To determine if Pools and Vaults share the same spender, just check your wallet pop-ups and on-chain records. I think HertzFlow should clearly show which contracts are permitted to use how much USDT—and where to revoke those permissions. Since test USDT has no real value, it’s perfect for practicing this habit. Your private key controls who can sign; your allowance controls how much of your tokens a contract can withdraw. Focusing only on your private key doesn’t complete permission management.
