No, it’s not in your wallet — it’s in the liquidity pool.
When a user buys your token, they deposit USDT (or other equivalent assets like BNB) into the liquidity pool. The pool then sends your issued tokens to the buyer, completing the swap. The USDT paid by the buyer remains in the pool.
If you want to withdraw those funds, you can do so in one of two ways:
By selling your tokens (i.e., swapping them for USDT in the pool), or
By removing liquidity from the pool.
PandaTool’s Liquidity Management tool allows any user to create, add, or remove liquidity easily.
