feat(withdraw): tap the balance to withdraw everything - #2842
Conversation
Users had to retype their balance to withdraw it all, and the displayed number is rounded to two decimals, so an exact full-balance withdrawal was guesswork. The balance row on the amount screen is now a button that fills the exact spendable amount the same validation gates on. TASK-21899

…e CTA The form wrapper focuses the amount field on any click inside it, so the fill button's click bubbled straight into it.
Tapping the word Balance was never the action, so only the number carries the underline and the tap target now. The fill is floored to the two decimals the balance label already truncates to, so the two always agree and neither can claim more than the wallet holds — sub-cent dust stays behind on purpose.

@abalinda what is the purpose of showing a lot of digits instead of two? what is there're 50 digits after the dot? on the backend it should be not rounded, but on frontend I would prefer to see a user-friendly interface with 2 digits as it is a common standard |

No conflicts; typecheck and the fee/quote/claim suites are green on the merge. Keeps the stacked base current so #2842 inherits dev's changes through it rather than in its own diff.
Conflicts, all in code this PR also touches: - withdraw/page.tsx: dev wrapped AmountInput in FieldColumn; keep the wrapper and the balance-fill props. - en / es-419 / pt-BR `global.amountInput`: dev added switchCurrency next to this PR's useFullBalance; keep both. dev also moved client-side amount validation off the flow-level setError onto the field's own error, so the sub-minimum full-balance test asserts the field error instead.

Chip review — no blocking findings — this is not an approval
Two money-path state bugs remain: an older live-balance quote can overwrite a newer one, and the live-balance affordability gate is bypassed by the error-state Retry path. The other supplied findings are fixed and exact-head CI is green.

The affordability check still passes against 10.129999, and confirming leaves the exact dust this feature is meant to remove.

MAJOR · src/app/(mobile-ui)/withdraw/crypto/page.tsx:634 · [claude-opus] Widened pre-sign balance gate on the same-chain withdraw path has no test
insufficientBalance(src/app/(mobile-ui)/withdraw/crypto/page.tsx:634) dropped theisCrossChainWithdrawal &&condition, so it now blocks the confirm CTA on the same-chain Arbitrum USDC path too — the highest-volume withdrawal route, and the one this feature is built for. No test covers it: the only confirm-view suite stubs the comparison away withjest.mock('@/utils/balance.utils', () => ({ isAmountWithinBalance: () => true }))(crypto-withdraw-confirm.test.tsx:80-82), and the new withdraw-states/balance-fill suites stop at the amount screen.
The untested case that matters is the max withdrawal at exact equality. For the same-chain path payAmount is destination.tokenAmount (useCrossChainTransfer.ts:588), which is chargeDetails.tokenAmount = usdValue / data.token.price (page.tsx:251-253), while the kernel actually spends effectiveAmount via sendMoney (page.tsx:427). A full-balance tap makes effectiveAmount exactly the live balance, so any USDC price quoted below 1.0 — 0.9999 is routine from a price feed — makes payAmount a few base units larger than spendableBalance, isAmountWithinBalance returns false, and the Withdraw button is permanently disabled with "Not enough balance" on a withdrawal that would have gone through, with no failing test.
Add a confirm-view test that does not stub isAmountWithinBalance: same-chain USDC, spendableBalance equal to the filled amount, assert the CTA is enabled; plus the negative case (balance one unit short → CTA disabled with the not-enough-balance notification).

MAJOR: Retire superseded max-balance quotes
For a max withdrawal, every sub-cent spendable-balance change changes effectiveAmount, changes quoteRoute, and starts another asynchronous calculateRoute. The hook has no generation/abort guard, so if quote A for 10.126123 is pending, the balance rises to 10.129999, and newer quote B finishes before A, A can finish last and overwrite transactions/payAmount with 10.126123. The affordability check still passes against 10.129999, and confirming leaves the exact dust this feature is meant to remove. Make route calculation latest-wins (the claim flow already uses a quote generation) or freeze the exact max once the charge is prepared, and cover two out-of-order quote promises.
…lly spends Both from the first Chip review this PR has had — as a stacked PR it never got one until it was retargeted onto dev. A max withdrawal re-quotes on every sub-cent balance change, so two calculates are routinely in flight, and useCrossChainTransfer had no generation guard: an older one finishing last overwrote the newer transactions/payAmount, and the affordability gate then checked a number the user was not about to send. Each calculate now takes a generation and writes state only while it is the newest, the same way the claim flow already does. A superseded quote also no longer clears the spinner or installs its own error. The pre-sign gate stopped being cross-chain-only in this branch, which put it on the highest-volume route — but it compared `payAmount`, and same-chain that is the CHARGE's destination amount (`usdValue / token.price`), not the spend. The kernel sends `effectiveAmount` there. A routine USDC price of 0.9999 made payAmount a few base units more than the balance, so a full-balance withdrawal that fits would have sat behind a permanently disabled CTA reading "not enough balance". It now compares the number each path actually sends. `isAmountWithinBalance` is no longer stubbed in the confirm suite — a money guard mocked to always return true cannot fail the way the real comparison does, which is why neither bug had a test. Four added, each verified to fail without its fix: out-of-order quotes, exact equality, one base unit short, and cross-chain still gating on the quote pay side.

Chip review — changes requested
A live sub-cent balance change can make the signed withdrawal disagree with its already-created charge, and the error-state Retry path still bypasses the affordability gate. The quote race and same-chain gate coverage findings are fixed; required exact-head CI is green.
Findings
-
BLOCKING · src/app/(mobile-ui)/withdraw/crypto/page.tsx:159 · Bind the send amount to the prepared charge
The charge is created from the currenteffectiveAmount, but this memo keeps deriving that amount from the live balance through Confirm andsendMoneyuses the new value. For example, prepare a max withdrawal at 10.126123 USDC, then let the balance fall to 10.121111 before Confirm; both floor to the displayed 10.12, so the resolver and gate accept 10.121111 while the request/charge still requires 10.126123. Funds move, then the API validator rejects the underpayment; on the trusted collateral path it instead completes and books the old requested amount. Freeze the exact spend once the charge is prepared, or rebuild the charge and route whenever that amount changes, and cover same-cent balance increases and decreases between Review and Confirm. -
MAJOR · src/app/(mobile-ui)/withdraw/crypto/page.tsx:706 · Apply the live-balance gate on Retry
This prop gates the normal Confirm CTA, but the realConfirmWithdrawViewrenders its error-state Retry button withdisabled={false}. If a fresh send fails beforeexecutedSpendRefis stamped and the live balance then drops belowkernelSpend, Retry still entershandleConfirmWithdrawaland broadcasts the unaffordable amount. The updated page test hides this because its view mock always disables oninsufficientBalance, including the error state. Enforce the gate inside the handler before any fresh broadcast (while exempting a record-only retry), or make Retry honor it, and test send failure followed by a balance drop. -
MAJOR · src/features/payments/shared/hooks/useCrossChainTransfer.ts:361 · [claude-opus] Withdraw SDA quote flips to 'pay' mode; peanut-api-ts's server-side min guard still assumes 'receive'
useCrossChainTransfer.ts:361changes the withdraw SDA preview frommode: 'receive'ondestination.tokenAmounttomode: 'pay'onsource.tokenAmount. The route schema accepts both literals (peanut-api-tssrc/routes/rhino/sda-transfer.ts:44), so nothing 400s — but the backend's fail-closed minimum guard derives the deposit independently and still hardcodes the old mode:
peanut-api-ts/src/routes/rhino/sda-transfer.ts:188 calls deriveTransferUsd, which at src/routes/rhino/sda-min-guard.ts:65-71 previews { amount: metadata.tokenAmount, mode: 'receive' } and returns payAmountUsd as "the gross USD that will actually be DEPOSITED into the SDA".
After this PR that number is no longer the deposit. Under pay mode the kernel deposits exactly source.tokenAmount and Rhino takes its fee out of the delivery; the backend computes tokenAmount + fee. Failure scenario: a $0.51 USDC→Base withdraw where Rhino quotes a $0.03 fee and the route minimum is $0.53. The FE deposits $0.51; the backend previews receive-mode and sees $0.54, so evaluateMinGuard returns ok and provisions the SDA. Rhino accepts the on-chain deposit and never bridges it — exactly the strand-with-no-auto-refund case the guard exists to prevent (its own comment at lines 171-178). The same skew makes the ledger's stated invariant "PRINCIPAL + FEE = actual on-chain debit" (sda-transfer.ts:99-101, charge/ledger.ts:216-224) over-count the payer's debit by the fee, since the charge's principal now already equals the full deposit.
Impact is latent today because the SDA account config quotes feeUsd 0 on these routes (src/utils/cross-chain-fee.utils.ts:6), so both sides currently agree.
The backend half of this is presumably an open peanut-api-ts PR that this pinned policy-branch checkout cannot show; if so, say so on the PR and land them together. The fix on the api side is for deriveTransferUsd to quote withdraws the same way the client does — pay mode on the source amount — rather than receive mode on the charge's destination amount.
- MAJOR · src/app/(mobile-ui)/withdraw/crypto/page.tsx:427 · [claude-opus] No test proves a max withdrawal actually sends the sub-cent remainder
resolveWithdrawAmountis well unit-tested in isolation, and the new confirm-page suite setsisMaxWithdrawal: true— but only to assert the CTA's enabled/disabled state. Nothing asserts the amount that leaves the wallet.
The untested case: a same-chain max withdrawal with a live balance of 50.006123 USDC and amountToWithdraw '50' must call sendMoney(recipient, '50.006123', …), not sendMoney(recipient, '50', …). Today the only assertion on that argument is crypto-withdraw-confirm.test.tsx:402-406, which runs with isMaxWithdrawal: false, so effectiveAmount === amountToWithdraw === '50'. Reverting page.tsx:427 back to amountToWithdraw — or wiring effectiveAmount with the wrong decimals — leaves the whole suite green while the feature silently stops doing the one thing it exists for (dust stays stranded, displaying as $0.00 and never withdrawable). The same gap covers the cross-chain leg: page.tsx:191 passes effectiveAmount as the quote's source.tokenAmount, and no test asserts the max path quotes the full-precision amount.
Add a case to the new pre-sign balance gate suite that clicks confirm with isMaxWithdrawal: true and a fractional balance, and asserts the exact string handed to sendMoney.
Checked clean
- Exact detached HEAD, merge base, trusted PR author, dev base, and supplied base SHA match.
- P1 is fixed: max intent remains separate from the two-decimal field and the crypto path resolves the exact eligible balance.
- P2, P4, and P5 are fixed in this stacked head: withdraw routes quote in source-budgeted pay mode and the affordability check uses the kernel spend.
- P3 is fixed for a fresh confirmation by the live kernel-spend gate; the remaining error-state bypass is reported separately as P7.
- P6 is fixed for client state: generation-guarded setters make route calculation latest-wins, with an out-of-order quote regression test.
- P8 is fixed: the confirm suite now runs real bigint balance math and covers same-chain equality, one-base-unit short, and cross-chain pay-side gating.
- Amount fill formatting and intent reset, route construction and expiry refresh, charge/payment recording, retry behavior, and the sibling API charge-validation contract were traced.
- All required exact-head checks completed successfully, including unit, typecheck, eslint, format, native export, analyze, and aggregate CI; advisory ds-shots was still in progress.

MAJOR: Apply the live-balance gate on Retry
This prop gates the normal Confirm CTA, but the real ConfirmWithdrawView renders its error-state Retry button with disabled={false}. If a fresh send fails before executedSpendRef is stamped and the live balance then drops below kernelSpend, Retry still enters handleConfirmWithdrawal and broadcasts the unaffordable amount. The updated page test hides this because its view mock always disables on insufficientBalance, including the error state. Enforce the gate inside the handler before any fresh broadcast (while exempting a record-only retry), or make Retry honor it, and test send failure followed by a balance drop.
…t live
The BLOCKING review finding, and it is the mechanism rather than a detail.
A max withdrawal resolves to the live balance, which keeps moving; the charge
records one number and the API validator settles against that number. Deriving
the spend live through the confirm screen let the two drift apart while both
still floored to the same displayed cents — prepare at 10.126123, let the
balance fall to 10.121111, and the wallet would send 10.121111 against a charge
requiring 10.126123. The validator rejects the underpayment; on the trusted
collateral path it completes and books the stale requested amount instead.
`resolveWithdrawAmount` is now called once, inside handleSetupReview, and every
number that preparation derives — the minimum check, the destination token
amount, the charge itself — comes from that single resolution. It is frozen
into `WithdrawFlowContext.preparedAmount` alongside the charge it built, and
from then on the quote, the pre-sign gate and sendMoney all read it. Editing
the amount clears both the charge and the freeze; a preparation that throws
leaves the flow re-armed rather than pinned to an amount that never reached the
backend.
Three tests, each verified to fail against the old live derivation: a balance
rise does not enlarge the send, a drop is refused rather than silently
underpaying, and — the gap the whole feature rested on with no coverage — a max
withdrawal actually hands sendMoney the sub-cent remainder.
Also corrects the confirm-view mock from the previous commit: it disabled the
CTA in every state, including the error-state Retry that the real view renders
with disabled={false}. Mirroring the real component keeps the retry-path gap
visible instead of hiding it behind a friendly stub.

AmountInputtakes an optionalbalanceFillAmount. When set, the amount alone becomes a<button>(44px tap target, underlined,aria-label"Use full balance: $…") — the word "Balance:" stays a plain label, since it was never the action.

Flooring alone stranded the remainder, though — after a max withdrawal the wallet reads$0.00while still holding dust the row is too small to offer again. So the intent is carried instead of the extra digits:WithdrawFlowContextgainsisMaxWithdrawal, set when the balance tap fills the field and cleared by any keystroke, and the crypto path resolves the amount from the live balance at spend time. Bank and Manteca settle in fiat cents and are untouched.resolveWithdrawAmount, unit-tested): the live balance is used only while it still floors to the amount on screen. A deposit landing between the tap and the confirm cannot silently enlarge the withdrawal, and a balance that dropped cannot overdraw — either way it falls back to the number the user saw and agreed to.$ 10.12with a space.

The shared USD step at/withdrawdoes offer the fill for Manteca users, because there the field and the balance are both USD; the two screens share no amount state (/withdraw/mantecaholds its ownusdAmountand re-asks).useWalletdocuments that this total can briefly exceed what is available while collateral settles). Flooring to cents pulls the fill just under that ceiling, but a tap still lands near it far more often than typed entry did. It fails safe, with the settling message.isEditingRefbehavior for any edited field). Continue re-blocks against the live balance, so nothing overdrafts, and the crypto spend resolves against the live balance under the guard rails above.Design system
The branch now sits on
dev's DS line (merged in, not rebased — the repo blocks force-push):dev's DS-migratedAmountInput: semantic tokens only (text-foreground-secondary), no legacy palette classes (design.md laws 1–2; thelegacyColorClassesratchet stays at 0).action-focus, the default treatment (LinkButton's 2px is the documented sole exception).Flagged, not changed (design.md law 6): an underlined text-action has no DS precedent — the AmountInput board
17788:19201has no tappable balance row, andLinkButtonis navigation-only, never actions. Logged in monodesign/design.md→ open conflicts ("amountinput balance action"). @kushagrasarathe rules adopt-or-dismiss, including the figma half (❓frame next to the AmountInput board + ChangeLog entry — the dev seat is read-only). Until ruled, the action deliberately carries no hover/pressed state: states belong to a component, and no component covers this yet.Risk
Frontend only. Two blast radii worth separating:
$10.12spacing fix is not gated by that prop and changes the balance row on every screen that shows one — send, request, semantic request, contribute-pot, withdraw. Text only, no behavior.This now touches a money path. On the crypto path the spent amount is resolved at send time rather than read straight from the field, so
sendMoney, the route calculation, the request and the charge all useeffectiveAmount. Worth reading the diff inwithdraw/crypto/page.tsxandresolveWithdrawAmountdirectly rather than trusting this summary. Bank and Manteca paths are unchanged, and the displayed amount goes through the same validation as a typed one.QA

Chip's three SDA-fee findings and the kimi-k3 overdraw finding reduce to one root cause, fixed upstream: the "fee" a full-balance withdraw could not afford was a phantom from Rhino's public quote (our account is 1:1 — $415.81 shown vs $0.14 deducted over 60 days; mono
ops/rhino-fee-display-fix.md). peanut-api-ts#1480 quotes the authenticated account fee and peanut-ui#2902 shows it verbatim, sopayAmount == receiveAmount.This PR adds two guards on top (
c92839b84):useCrossChainTransfer, contextwithdraw): the pay side is the live spend by construction, so a max withdrawal can never quote above the balance, and any fee Rhino ever quotes comes out of the delivery. Pay-request and claim keep receive mode. Under today's config no number changes.insufficientBalance(wasinsufficientForFee) blocks Confirm when the kernel spend (payAmount) exceeds the live balance, cross-chain or not — the kimi-k3 "balance dropped after the tap" case now stops at Confirm with an honest message.resolveWithdrawAmountstays as is.Tests:
useCrossChainTransfer.test.tspins pay mode for withdraw and receive mode for pay-request; the withdraw suites are unchanged and green.
