Thanks for using CodeRabbit! It's free for OSS, and your support helps us grow. If you like it, consider giving us a shout-out.
A rabbit checks each TWAP sign,
“How much?” now shows in clear design.
For finite sums, the tokens gleam,
Max gets “unlimited” on the screen.
The approval steps hop into line.

- Around line 38-50: Update useEoaTwapPlan’s amount passed to
buildEoaTwapConfirmationPendingSteps to match the EOA poller’s normalized
request amount, including the zero-to-sell fallback and Dai-like unlimited rule,

Use the normalized poller amount for EOA labels.
When the vault-relayer allowance already covers the trade, useGetAmountToSignApprove() returns a zero CurrencyAmount. The EOA poller path instead requests the TWAP sell amount when its own allowance is insufficient. The stepper therefore can display Approve 0 TOKEN or Permit 0 TOKEN while the wallet requests the sell amount. This affects both partial and unlimited selections because the zero return occurs before those selection branches.
Pass the same normalized poller amount to the label builder, including the zero-to-sell fallback and the Dai-like unlimited rule.
