Issue Summary

When attempting to sign or broadcast a transaction using the Station wallet extension, the process fails with a "transaction rejected by user" error displayed in the UI. The browser console shows a WalletError indicating "User denied, extension popup was closed," even if the user did not explicitly close the popup or reject the transaction. Interestingly, the stack trace mentions KeplrExtension, suggesting a potential abstraction or configuration issue in how the wallet provider handles the Station extension.

Reproduction Steps

Connect a Station wallet to the application
Initiate any transaction (e.g., Swap, Place Limit, or Provide Liquidity)
Wait for the Station extension popup to appear
Observe that the transaction fails with "transaction rejected by user in the UI
Check the browser console for the WalletError and stack trace

Expected Behavior

The transaction should be successfully signed and broadcast when the user approves it in the Station extension popup. If a rejection occurs, it should only be when the user explicitly cancels the action.

Actual Behavior

The transaction is immediately rejected with the following error logged in the console:

Terra Classic transaction error: WalletError: User denied, extension popup was closed.

    at async KeplrExtension.broadcastTx ( @goblinhunt_cosmes_wallet.js?v=a78dd4be:5797:18)

The UI displays: transaction rejected by user.

Console Logs

    at async KeplrExtension.broadcastTx ( @goblinhunt_cosmes_wallet.js?v=a78dd4be:5797:18)

Severity / Impact

Blocker: This blocks all on-chain interactions for users using the Station wallet. The reference to KeplrExtension in the stack trace for a Station wallet error suggests a significant bug in the wallet provider's extension detection or routing logic.

Still hinders the last checklist of https://gitlab.com/PlasticDigits/cl8y-dex-terraclassic/-/work_items/147 being fully verified due to lack of testing with station wallet.

Fix landed on `main` (`2d92b13`)

@Brouie — please verify Station extension signing on LocalTerra and mainnet (swap, place limit, provide liquidity).

Root cause

StationExtension is an alias of cosmes KeplrExtension (Keplr in stack traces is expected).
Station’s window.station.keplr shim mishandles signDirect and can return User denied, extension popup was closed even when the user did not reject.
Overlapping sign prompts and a second signAmino after approval (fee-guard retry) could also close the popup.

Changes

Cosmes patch — StationController always uses useAminoSigning = true for extension connects (#208).
applyStationKeplrShimSignDefaults() — preferNoSetFee / preferNoSetMemo on connect + before each broadcast.
Mainnet Station — experimentalSuggestChain before/after connect (same gas steps as Keplr).
withTerraWalletSignLock — serializes extension broadcastTx so only one popup is active.
Removed amino re-sign retry after fee guard (single sign only; guard still surfaces undershoot copy).
Retail errors — false popup-closed → actionable Station reconnect copy.

Docs / agents

Verification checklist

cd frontend-dapp && npm ci && npm run test:run (includes cosmesPatch127.test.ts, terraWalletSignLock.test.ts)
Connect Station extension on LocalTerra (VITE_NETWORK=local) — approve addNetwork if prompted (#207)
Connect Station extension on mainnet/testnet — approve Terra Classic chain update if prompted
Swap — sign once, tx broadcasts (no immediate “transaction rejected by user”)
Place limit (CW20 path) — both allowance + place msgs sign successfully
Provide liquidity — multi-tx sequence completes
Explicit Reject in Station still shows “Transaction rejected by user”
Console: no false WalletError: User denied, extension popup was closed on approve

Leaving issue open until Station QA on real hardware confirms.

Fix landed on `main` (commit `2d92b13` + doc follow-up)

Station extension txs were routed through signDirect on mainnet and a second signAmino could run after the user already approved the first prompt. Station’s Keplr shim then often reported User denied, extension popup was closed even when the user intended to approve — stack traces showing KeplrExtension are expected (StationExtension is an alias).

What changed

Cosmes patch: StationController → useAminoSigning = true for all extension connects; one signAmino per tx (no fee-guard retry re-prompt).
applyStationKeplrShimSignDefaults() on Station connect + before every broadcastTerraExecuteContracts.
withTerraWalletSignLock serializes extension broadcastTx so overlapping popups cannot clobber each other.
Mainnet: experimentalSuggestChain before/after connect for Station (gas step refresh).
Retail errors: false popup-closed → actionable Station copy (not generic “rejected by user”).
Docs/skills: § Station extension signing, skills/AGENTS_FRONTEND_STATION_SIGNING.md.

Verification checklist

cd frontend-dapp && npm ci (patch applies: @goblinhunt/cosmes@0.0.71-ghunt.21 ✔)
npm run test:run — cosmesPatch127.test.ts, terraWalletSignLock.test.ts, terraBroadcast.test.ts
Mainnet + Station extension: connect → swap succeeds after approving one popup
LocalTerra + Station: connect (approve addNetwork / chain update if prompted) → swap / place limit / provide liquidity
Explicit reject still shows decline copy; no false popup-closed on happy path
Console: KeplrExtension in stack is OK when wallet type is Station

@brouie — please run the checklist above on your Station build (mainnet + local if available) and reply here. Leaving the issue open until verified.

Closing as local testing cannot be done on station wallet, only other wallets. terrastation does not work properly with localterra.
