Summary

Replaces deprecated Safe / wallet hooks with their equivalent atom.

Most changes are imports, so I suggest one quick pass to mark those as reviewed first.

Closes https://linear.app/cowswap/issue/FE-251/update-wallet-related-atoms-without-updaters
Closes https://linear.app/cowswap/issue/FE-249/replace-useaccounttype-with-accounttypeatom

To Test

Wallets: EOA, Safe App, Safe via WalletConnect, imported Safe (Rabby/Ambire), one other smart-contract wallet.

On each wallet

  • Network selector + sell-token chain list: blocked only for Safe App and Safe WalletConnect (peer name includes "safe"). Imported injected Safes and non-Safe WC can switch.
  • Place a SWAP. Confirm: EOA gets a real permit if needed; Safe/SCW do not.
  • Place a LIMIT. On EOA, check an ETH pair rate looks normal.
  • Check TWAP CTA/placement: EOA uses EOA TWAP; Safe App, Safe WC, and imported Safes use the Safe path, not EOA.

Also

  • Hard refresh as EOA: permit appears after wallet type resolves, no fake permit.
  • Disconnect/reconnect Safe vs EOA: network selector and permit/TWAP UI follow the new wallet.
  • Account orders: Safe orders still show Safe signing/cancel behaviour.
  • Minimum pass if short on time: EOA, Safe App, Safe WalletConnect, Rabby-imported Safe — switch networks, one swap, one limit, TWAP CTA.

Summary by CodeRabbit

Summary

  • Bug Fixes
    • Improved automatic rate direction selection, including handling of native tokens and currencies that are not yet available.
    • Refined wallet-status handling so features such as permit eligibility and off-chain signing respond appropriately when wallet details are unknown.
    • Improved Safe and WalletConnect detection for network-switch availability and other wallet-specific behavior.
    • Wallet account checks now retry transient lookup failures and can recover after an unsuccessful check.

Walkthrough

Wallet metadata and frontend consumers now use Jotai atoms for wallet status. Account-type lookup supports retries and refresh, and wallet status distinguishes loading from missing or failed results. Rate and order views use currency-aware address comparisons to select price direction. An end-to-end market-order test waits for currency resolution before selecting tokens.

Changes

Wallet state atoms

Layer / File(s) Summary
Wallet metadata state and classification
libs/wallet/src/wagmi/state/walletMetadata.atoms.ts, libs/wallet/src/wagmi/state/walletMetadata.atoms.test.ts
Wallet metadata atoms provide Safe Apps SDK state, network-switch status, refreshable account lookup, and wallet classification. Tests cover these states and retry behavior.
Wallet updater and API migration
libs/wallet/src/api/types.ts, libs/wallet/src/wagmi/updater.ts, libs/wallet/src/wagmi/hooks/*, libs/wallet/src/api/hooks/*, libs/wallet/src/index.ts
Wallet updater code reads wallet state atoms and retains WalletConnect peer metadata. Replaced hooks are removed. Batch sending and network switching read atom state.
Frontend wallet-state consumers
apps/cowswap-frontend/src/common/*, apps/cowswap-frontend/src/entities/*, apps/cowswap-frontend/src/legacy/*, apps/cowswap-frontend/src/modules/*
Frontend components, hooks, and updaters read wallet status atoms. Related tests configure atom values. Some consumers handle nullable smart-contract-wallet status.
TWAP wallet-state consumers
apps/cowswap-frontend/src/modules/twap/*
TWAP code and tests read Safe-wallet atoms. Pending wallet-type inputs use null.

Currency inversion

Layer / File(s) Summary
Currency address comparisons
apps/cowswap-frontend/src/common/pure/RateInfo/*, apps/cowswap-frontend/src/modules/limitOrders/containers/RateInput/index.tsx, apps/cowswap-frontend/src/modules/ordersTable/containers/OrderRow/OrderRow.container.tsx
Smart-quote inversion accounts for missing addresses and native currencies. Limit-order and order-row inversion compare currency addresses.

End-to-end currency resolution

Layer / File(s) Summary
Market-order currency wait
apps/cowswap-e2e-tests/src/tests/market-orders.spec.ts
The market-order test waits for both currencies to resolve before selecting tokens.

Priority: ⬇️ Low

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Feature

Merge Risk: 🟡 Moderate · up to d46a7

A smart-contract wallet can briefly look like a regular wallet while its type is still being checked. During that time it is offered permit and off-chain signing flows it can't use. Also, if the account-type check keeps failing, regular-wallet features stay off until the user reconnects. Both should be fixed before merging.

⚠️ AI Review (Grok 4.7, worked 6m): imported Safes lose network switching; permit stays off after eth_getCode failure

Finding: [BLOCKING] Imported Safes can no longer switch networks

  • Location: libs/wallet/src/wagmi/state/walletMetadata.atoms.ts:59 (isNetworkSwitchUnsupportedAtom), consumed by useSwitchNetwork and useChainsToSelect
  • This one is important: useNetworkSwitchUnsupported only blocked Safe Apps and WalletConnect peers whose name contains "safe". The replacement atom treats every non-Safe-App wallet with gnosisSafeInfo as Safe-via-WC (isSafeViaWcAtom, including the imported-Safe branch). Rabby is exempt; Ambire and other injected Safes are not.
  • Once Safe info loads, useSwitchNetwork returns immediately and the token selector gets an empty chain list. Those wallets could switch chains before.
  • Receipt: deleted useNetworkSwitchUnsupported / useIsSafeViaWc on develop; useIsPossibleSafe already calls out Ambire and Rabby as imported injected Safes. The new unit test covers Safe App and Rabby only.
  • No existing review thread covers this.

QA evidence needed

  • Please add ER-vs-AR for network switching and the sell-token chain list with a Safe App, Safe via WalletConnect, Rabby-imported Safe, and Ambire-imported Safe.

Suggested fix

  • Keep the Rabby exemption, and do not use the broad isSafeViaWcAtom for this gate. Match the old hook: Safe App, or WalletConnect peer name containing "safe".
  • Add a test for an injected non-Rabby connector with gnosisSafeInfo set, expecting network switch to stay supported.

Finding: [BLOCKING] A failed account-type check leaves permits disabled

  • Location: apps/cowswap-frontend/src/common/hooks/featureFlags/useIsPermitEnabled.ts:9 and accountTypeAsyncAtom in libs/wallet/src/wagmi/state/walletMetadata.atoms.ts
  • useIsSmartContractWallet collapsed a missing or failed eth_getCode to false, so === false still treated the wallet as an EOA and permits stayed available. isSmartContractWalletAtom returns null while the check is loading and again when accountTypeAsyncAtom throws. null === false is false, so permits stay off.
  • isEoaAtom does the opposite on hasError and returns true. The async atom does not retry after a throw, so one RPC failure sticks until walletInfoAtom changes.
  • The same === false check in SwapWidget hides the cross-chain unlock screen for that stuck null.
  • Receipt: deleted useAccountType catch returned undefined "to avoid false negatives during init". Permit display is load-bearing (confirm-screen real-vs-fake permit). Tests only set the atom to true and false.

QA evidence needed

  • Please add ER-vs-AR for the SWAP and LIMIT confirm screen with an EOA, a smart-contract wallet, and an eth_getCode failure, in Firefox and a warm session. Expected: EOA permits still appear; a contract wallet does not get a fake permit.

Suggested fix

  • On hasError, resolve isSmartContractWalletAtom the same way isEoaAtom does, or retry the code lookup.
  • Keep null as "still loading" if that is intentional, and cover null in useIsPermitEnabled.

Finding: [QUESTION] Smart quote now inverts native pairs

  • Location: apps/cowswap-frontend/src/common/pure/RateInfo/index.tsx:202
  • getAddress returned null for native currencies, and this effect returned before setting isInverted. getCurrencyAddress returns a sentinel, so USDC to ETH (and ETH to a non-stable with the smaller amount on the buy side) now flips the rate. RateInput has the same helper swap.
  • Why change quote direction in a wallet-atom migration? If this is intentional, it needs a limit-order rate check on an ETH pair.
Review scope and related context

Reviewed PR head cf6a8a07 against develop. Draft PR, no review threads. Linear, Vercel, and CodeRabbit comments do not discuss these paths.

Checked and not posted:

  • Hook-to-atom call sites for isSafeWalletAtom match !!gnosisSafeInfo.
  • safeAppsSdkAtom follows isSafeAppAtom === true, which is slightly wider than connectionType === GNOSIS_SAFE because isSafeConnector also matches the Safe connector id. SDK getInfo failure is already caught.
  • TWAP isSafeViaWc === true does not by itself reclassify an imported Safe; isSafeWalletAtom already did that.
  • @cowprotocol/wallet is private; removed hook exports have no remaining in-repo callers.

Verify these findings against current PR head. Fix only what is still valid, keep the change minimal, and add targeted tests.

1. Network switch
- libs/wallet/src/wagmi/state/walletMetadata.atoms.ts isNetworkSwitchUnsupportedAtom
- useNetworkSwitchUnsupported used the narrow useIsSafeViaWc (WalletConnect peer name contains "safe") OR useIsSafeApp, with an early Rabby return.
- isSafeViaWcAtom returns true for any non-Safe-App wallet once gnosisSafeInfoAtom is set, so Ambire-style imported Safes can no longer switch networks or see sell-token chains.
- Restore the narrow predicate. Test injected non-Rabby + gnosisSafeInfo => switch supported; Safe App and Safe WalletConnect => unsupported; Rabby + gnosisSafeInfo => supported.

2. Permit / account type
- useIsPermitEnabled treats isSmartContractWalletAtom === false as EOA.
- accountTypeAsyncAtom throws on getCode failure; accountTypeAtom and isSmartContractWalletAtom then stay null, so permits stay disabled. isEoaAtom returns true on hasError.
- Align the error path with isEoaAtom or retry. Add a useIsPermitEnabled test for null.

3. RateInfo native inversion
- Only change this if the author did not intend smart-quote inversion for native pairs. Old getAddress(native) was null and the effect skipped setCurrentIsInverted.

Review comments at @apps/cowswap-frontend/src/common/pure/RateInfo/index.tsx:
- Line 206: Update the `RateInfo` quote-selection logic to remove the early
return for native currencies and compare currencies using `getCurrencyAddress`,
so `currentIsInverted` reflects the selected quote currency for native-currency
pairs as well.

Review comments at @libs/wallet/src/wagmi/state/walletMetadata.atoms.ts:
- Line 145: Update the getCode error handling in the wallet-type state flow so a
rejected lookup preserves an unknown wallet type rather than returning false;
ensure consumers such as useIsPermitEnabled and WalletUpdater do not enable
EOA-only behavior from a failed lookup, and provide a retry path. Update the
rejection test to assert the unknown state.

Add a production retry path for accountTypeAsyncAtom.

After four failed getCode calls, accountTypeLoadableAtom enters hasError. Its dependencies can remain unchanged after the RPC recovers, and no production code calls set(accountTypeAsyncAtom) to retry. In that state, accountTypeAtom remains null, so EOA-only flows gated by isEoaAtom === true remain unavailable. Add a production refresh trigger for this failure path.

accountTypeAsyncAtom already retries getCode using the retry() util when it throws an error, or when wallet info changes. No need for this change.

@Danziger, thanks for clarifying. You are correct that retry() handles transient failures and wallet-info changes trigger a new lookup.

The finding concerns recovery after those retries are exhausted, with wallet info unchanged. I checked the current code: WalletUpdater has no refresh trigger, and the only set(accountTypeAsyncAtom) call is in the test at Line 452. In that case, RPC recovery alone leaves accountTypeAtom and isEoaAtom at null.

I accept your decision not to add a recovery trigger. The remaining limitation is that recovery requires a wallet-info change.

Timestamp: 2026-10-07T15:42:01.308Z
Learning: In cowprotocol/cowswap, libs/wallet/src/wagmi/state/walletMetadata.atoms.ts uses retry() within accountTypeAsyncAtom to retry failed getCode calls, and walletInfoAtom changes trigger a new lookup. The maintainer considers these recovery mechanisms sufficient and declined an additional production refresh trigger after retries are exhausted.

Learning: In CoW Swap, `libs/wallet/src/wagmi/state/walletMetadata.atoms.ts` intentionally returns `false` from `isSmartContractWalletAtom` while `getCode` is loading. This preserves the old hook’s behavior and avoids treating pending classification as a smart-contract wallet. The maintainer reports that returning `null` during loading breaks E2E tests. Lookup failures remain `null` and are retried in `WalletUpdater`. Do not recommend changing the loading value to `null` solely because classification is pending.

Hey @Danziger , great!
But there is 1 issue:

  1. connect to eoa
  2. sign a permit, don't place an order
  3. disconnect a wallet
  4. clear out the local storage, hard refresh
  5. reconnect the wallet
  6. pick the same token pair --> swap button is disabled.

I did not manage to reproduce this issue on Prod. Could you please take a look at it?

@elena-zh Can you reproduce it with a different wallet? Otherwise, do you have any setting in Rabby forcing it to re-connect? I cannot reproduce it, but also it doesn't work the same for me: after disconnecting the wallet and the hard reload, the wallet will be disconnected unless I click "Connect" again.

Hey @Danziger , I'll approve the PR with the hope that it will never happen to regular users.
No, I don't have a special setting in Rabby to reconnect the app on refresh: there is something in reown that forces it.

Looks good, thanks for the refactor!

The only thing that bothers me a bit is this usage useAtomValue(isSafeViaWcAtom) === true

I think in some cases it can be done without === true, no?

Also, personally, I would have kept things like const useIsSafeApp = () => useAtomValue(isSafeAppAtom) to keep the diff smaller.

Yes, but in some other ones TS might complain. In any case, see comment here: #8307 (comment)

I'll address my own comments in a new PR as I didn't want to touch this one as it was already reviewed.

Also, personally, I would have kept things like const useIsSafeApp = () => useAtomValue(isSafeAppAtom) to keep the diff smaller.

To keep the diff smaller yes, but I'd prefer to avoid these thin wrappers around useAtomValue and instead just inline it, so it was intentional to remove them.
