Understanding approval transactions

When using the USDFI Protocol for the first time, you will be required to approve the token that you wish to swap or add liquidity to. This gives the USDFI Protocol permission to access the token in your wallet and execute the swap or liquidity addition.

It is important to note that each token from a specific wallet will require a one-time approval. This means that once a token has been approved for use in the USDFI Protocol, it will not need to be approved again for future swaps or liquidity additions.

When swapping tokens on USDFI Protocol, you will be prompted with a message asking for approval. This message may appear as a pop-up or a button labeled "Allow" or "Approve". Once you select this option, you will be able to proceed with the token swap.

It is important to note that approving a token is considered a transaction, and as such, it will require a network fee to be paid. This fee will vary depending on the current network congestion and the specific blockchain being used.
