Hi I exchanged my Matic Polygon for USDT (PoS) on the Polygon network using Trust Wallet. However, I’m encountering errors when I attempt to swap or transfer the token to another chain token or even within the same chain (Polygon).
Here’s the process I’ve been following:
- Open Trust Wallet.
- Navigate to the USDT token.
- Select ‘Swap’.
- Choose to swap from Polygon USDT to either Polygon Matic or BSC Chain Link.
- Approve USDT.
After approving USDT, I encounter an error on the next page stating ‘Quote expired’. When I refresh the page, I see ‘Swapper Bad Allowance’. If I cancel the page, the transaction gets stuck in pending. The nonce number remains the same with each new attempt, and every failed attempt gets removed from the list due to ERC standards.
