Summary

Fixes sentence fragmentation, isolated translation tokens, and binary plural checks (=== 1) across 6 frontend components that cause broken grammar, case/gender agreement, and rigid word order in non-English locales (specifically Slavic languages like Russian requiring 3-form plurals: one, few, many).

Key Accomplishments:

  • Replaced hardcoded binary ternary checks with native Lingui <Plural/> macros.
  • Unified fragmented sentences split across isolated <Trans> blocks or around <TokenSymbol/> into single continuous <Trans> containers.
  • Updated and compiled the Russian (ru-RU.po) and English (en-US.po) catalogs with proper ICU plural categories and natural word orders.

To Test

1. Safe Transaction Signatures (ActivityDetails.tsx)

  1. Switch app language to Russian
  2. Open an account transaction requiring Gnosis Safe signatures with threshold values of 1, 2-4, and 5+ signatures.
  • With 1 signature: Should display "Требуется 1 подпись" (not "1 подпись обязательный").
  • With 2–4 signatures: Should display "Требуются 2 (3, 4) подписи".
  • With 5+ signatures: Should display "Требуется 5 подписей".
  • Pending signatures alert displays inflected forms correctly ("Требуется ещё 1 подпись", "Требуются ещё 2 подписи", etc.).

2. Affected Permit Banner (ActiveOrdersWithAffectedPermit.tsx)

  1. Trigger a partial approval with 1, 2–4, and 5+ pending orders relying on the permit.
  • Title correctly inflects the plural form ("... 1 другой ордер", "... 2 другие ордера", "... 5 других ордеров").
  • Dropdown footer correctly forms full sentence with plural agreement instead of isolated "is/are" tokens.

3. Warning Tooltips (WarningTooltip.pure.tsx)

  1. Hover over status badges for orders with insufficient balance or insufficient allowance (both scheduled and immediate).
  • Sentences flow naturally as complete clauses around the token symbol (e.g. "Обнаружен недостаточный баланс [TOKEN].", "Для исполнения требуется достаточный баланс [TOKEN].").

4. Native Sell Warning Banner (SellNativeWarningBanner/index.tsx)

  1. Attempt to sell native currency on a non-swap order (e.g. Limit Order / TWAP).
  • Button text reads "Сначала обернуть [NATIVE] в [WRAPPED]" with the adverb properly preceding the action clause rather than trailing as an isolated fragment.

5. Load More Orders Pagination (LoadMoreOrdersSection.tsx)

  1. View the orders table with pagination when there are 1, 2–4, and 5+ open orders.
  • Correctly applies 3-form plural strings ("Найден 1 открытый ордер...", "Найдены 2 открытых ордера...", "Найдено 5 открытых ордеров...").

6. Order Progress Bar Finished Step (FinishedStep.tsx)

  1. Complete an order where surplus or tips are available, with multiple solvers (>3).
  • "View more" button uses unified <Plural> macro ("Показать ещё 2", "Показать ещё 5").
  • Share button renders unbroken string for both surplus and tips ("Поделитесь этой победой!", "Поделиться советом!").

Background

Sentence fragmentation and isolated tokens prevent translators in Crowdin from producing grammatically correct translations in languages with grammatical case and complex pluralization rules (e.g. Slavic languages with one, few, many, other forms):

  1. ActivityDetails.tsx: Hardcoded gnosisSafeThreshold === 1 ? t'signature is' : t'signatures are' and isolated t'required' forced English pluralization and broken adjective agreements (1 подпись обязательный, 5 подписи обязательный). Resolved via <Plural/>.
  2. ActiveOrdersWithAffectedPermit.tsx: Assembling sentences using isolated tokens (areIs, orderWord) prevented declension agreements. Inlined <Plural/> blocks into <Trans>.
  3. WarningTooltip.pure.tsx: Isolating trailing words like balance. and token before creation. forced rigid English word order and prevented target languages from positioning nouns before the token in the genitive case. Unified into single <Trans> containers.
  4. SellNativeWarningBanner/index.tsx: Trailing isolated <Trans>first.</Trans> prevented placing "first" (сначала) before the verb clause. Unified into the button's <Trans>.
  5. LoadMoreOrdersSection.tsx: Binary totalOpenOrders === 1 condition lacked support for 3-form plurals. Replaced with <Plural/>.
  6. FinishedStep.tsx: Split strings like <Trans>View</Trans> {count} <Trans>more</Trans> and <Trans>Share this</Trans> {win/tip}! caused case and spacing issues. Unified into complete phrases.

(Note: Minor compound clauses in ModalTopContent.tsx, InitialStep.tsx, and SolvingStep.tsx that allowed semantic workarounds were already resolved directly in Crowdin).

Walkthrough

The frontend replaces React Plural components and fragmented translation blocks with Lingui plural macros and consolidated ICU messages. English and Russian catalogs add the corresponding active entries and obsolete superseded fragments.

Changes

ICU pluralization

Layer / File(s) Summary
Locale catalog entries
apps/cowswap-frontend/src/locales/*.po
The catalogs add ICU plural entries for signatures, approvals, balances, open orders, wrapping, solver labels, and sharing text. Superseded fragments become obsolete.
Safe signature counts
apps/cowswap-frontend/src/modules/account/containers/Transaction/ActivityDetails.tsx
Safe transaction details use the plural macro for required and pending signature counts.
Order approval and balance warnings
apps/cowswap-frontend/src/modules/erc20Approve/..., apps/cowswap-frontend/src/modules/ordersTable/..., apps/cowswap-frontend/src/modules/tradeWidgetAddons/...
Approval, balance, and allowance messages use consolidated translation entries. The native-token wrap label includes “first” inside one translation block.
Order and solver count labels
apps/cowswap-frontend/src/modules/ordersTable/..., apps/cowswap-frontend/src/modules/orderProgressBar/...
Open-order and hidden-solver labels use Lingui plural macros. Solver sharing text uses a consolidated translation entry.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to b776d

Changing locale without remounting can leave the open-order summary untranslated until another render occurs. This should be fixed before merge.

Suggested reviewers: danziger, shoom3301

Poem

A rabbit counts messages in flight,
Plural forms settle into the right.
Orders and signatures use one clear way,
Balance warnings speak plain today.
“Wrap first,” says the button, bright.

⚠️ AI Review (Codex GPT-5): coordinate the overlapping i18n changes

Finding: [BLOCKING] Establish one i18n source of truth and merge order

Please coordinate this translation stack before merging: this PR overlaps the generated catalogs in #8058 and the open Crowdin update #8031. We need an i18n owner to choose the source of truth and merge order; then rebase, regenerate catalogs once, resolve the existing review threads, and run generated-files/CI plus Russian-language QA.

Suggested next step

  • Choose the authoritative source and merge order, regenerate once, resolve active threads, and complete CI plus Russian-language QA.
🤖 Prompt for AI agents
Coordinate PR #8057 with #8058 and #8031. Identify the authoritative i18n source, assign ownership for overlaps, follow the agreed merge order, regenerate catalogs, and verify CI and rendered Russian strings.

Remove the duplicate active catalog block.

The ICU entries in Lines 8607-8657 repeat active entries from Lines 8553-8604. This includes signature counts, approval warnings, balance warnings, wrapping, open-order counts, solver controls, and Share this tip!.

The existing-order warning also has two active variants. Keep the plural-aware There is/There are entry and remove the stale hard-coded There are variant.

Regenerate en-US.po once from the authoritative source. Keep one active definition per msgid; duplicate definitions can fail catalog compilation or produce inconsistent generated output.

Yep, thanks for noting! That's the motivation for #8058
TL;DR some strings were incorrect when imported into Crowdin, #8058 restores the correct ones synced with the new stuff from Crowdin. I.e., #8058 now contains the most relevant translation, compared to develop/Crowdin.

I'm afreaid all these translations will also be lost when sync it with crowdin sync. @azebuado , am I right?

The way we could approach this is merge (#8057) into develop, rebase on #8058 and merge that into develop. This way there won't be any conflicts during merge in the translation files.
