feePayer="seller" still adds fee to sender amount in CheckoutWidget

[rcnavas]

Testing with thirdweb@5.105.5, using setting feePayer="seller", it still adds 0.3% to the amount shown to the buyer/sender

TOOL-4970 feePayer="seller" still adds fee to sender amount in CheckoutWidget

Thanks for the report, looking into this

[joaquim-verges]

fix released in thirdweb@5.105.7

[rcnavas]

This still happens to me with latest release

[joaquim-verges]

@rcnavas the feePayer prop only applies when paying with the same currency. If paying with a different currency, the swap fees need to be on the user side due to the nature of the transaction.

so in your example, feePayer="seller" will only apply if im paying with token 0x3c499c542cef5e3811e1192ce70d8cc03d5c3359 (user will pay exactly 1 of those tokens, and seller will receive 0.97)

are you seeing a different behavior?

[rcnavas]

@joaquim-verges I see a different behavior, in my test page, the amount = 1.0, token = USDC on Polygon. When i reach the "Select Token" screen, the amount shown is 1.003 for USDC on Polygon.
This is version thirdweb@5.105.9

Ah I see. I think we don't apply it on this "pre-quote" list, but if you select usdc polygon here it should fetch the final quote and apply the fee payer correctly. Can you confirm?

Will fix the ore quote one too

[rcnavas]

@joaquim-verges right... it seems like the "Confirm Payment" screen show the correct value...

[joaquim-verges]

@rcnavas released the fix for the pre-quote list in thirdweb@5.105.10

thanks again for the report!
