Summary
Audited the transaction detail view against README UI policies and fixed all violations found.
Violations fixed:
Clickable affordance missing on Etherscan links — External link icons on addresses and transaction hash had no visible border or hover state. Added
border border-border px-1 hover:bg-fg hover:text-bgper the clickable affordance policy.Address line missing color dot and Etherscan link when ENS name is shown — When an address had an ENS name, the full address was displayed without its color dot or Etherscan link (only the ENS name line had them). Now both the ENS name line and the full address line show the color dot, and the Etherscan link is on the address line.
Closes #59
Code Review — PR #62
Verdict: Needs rework — the PR fixes real issues (clickable affordance styling, ENS address display) but does not address any of the 3 specific violations sneak reported in #59.
Issue #59 violations vs. this PR:
0xdAC1…) missing Etherscan link, and symbol is interposed between color dot and addressWhat the PR does fix (valid improvements, but not what #59 asks for):
<a>tags on From/To/TxHash now have proper border + hover stylingRequired changes:
These are the core complaints in #59 and must be resolved before merge.
Rework complete
Addressed all 3 violations from #59:
Protocol name Etherscan link — Protocol entries (e.g. "Uniswap Universal Router") now show color dot + name + Etherscan link to the contract address.
Token address display fixed — Token entries (e.g. Token In, Token Out) now show symbol on its own line, then color dot + full contract address + Etherscan link. Symbol is no longer interposed between the dot and the address.
Raw data moved to bottom — Raw data section is now rendered after the transaction hash, so it no longer pushes useful info off screen.
docker build .passes.Code Review — PR #62 (second review after rework)
Verdict: ✅ Ready to merge
All three violations from #59 are now addressed:
Protocol name Etherscan link — Protocol entries (e.g. "Uniswap Universal Router") now display color dot + name + Etherscan link to the contract address. Uses
/address/URL correctly.Token address display — Token entries use a dedicated

Markingmerge-ready.@clawbot - this is not a work instruction, but a request for opinion and advice. should we be reusing the contract address display format from the address-token page here, when one of the transaction parties is an ERC20 contract? or is that stupid bc the transaction party will usually be a swap contract not an ERC20 contract?
Your intuition is right — reusing the token display format for transaction parties would usually be misleading.
In practice, the
toaddress on a swap transaction is almost always a router contract (Uniswap Universal Router, 1inch AggregationRouter, etc.), not an ERC20 contract. Showing it with the token-style display (symbol, token link) would be confusing because:/token/page would 404 or show garbage for them.transfer()call), thetois usually the recipient wallet, not the token contract. The token contract is thetoof the outer transaction only if you're calling the token directly — which is uncommon in normal usage.The one edge case where it could make sense: if the
toaddress is a known ERC20 and the method is something liketransfer()orapprove(), you could show the token display. But that's a narrow case and might add complexity for little payoff — the decoded data already surfaces the token info.tl;dr: Current separation is correct. Protocol/router contracts get the protocol display (name +
/address/Etherscan link), token fields in decoded data get the token display (symbol +/token/link). Mixing them would create more confusion than clarity.The etherscan links don't look like the etherscan links in other places. Please audit all additions/changes in this PR for consistency with existing UI elements on other views.

The
etherscanLinkHtml()helper in transactionDetail.js had extra classes not used by any other view:border border-border(no other view adds a border to etherscan links)px-1(no other view adds horizontal padding)hover:bg-fg hover:text-bg(no other view adds hover color inversion)cursor-pointer(no other view adds this)All other views (addressDetail, addressToken, confirmTx, send, receive, home, txStatus) consistently use only
class="inline-flex items-center"on etherscan<a>tags.Fixed by removing the extra classes to match the existing pattern exactly.
I also audited all other additions in this PR (blockies, color dots, copyable elements, raw data section, calldata rendering) and they are consistent with existing patterns in other views.

Fix: V4 Swap Token Display Bug
Problem: All Uniswap V4 swaps (e.g. USDT→USDC) displayed as "Swap ETH → ETH" on both the transaction detail and approval pages. The decoded calldata showed
Token In: ETH (native)andToken Out: ETH.Root cause: The
V4_SWAPcommand (0x10) was listed inCOMMAND_NAMESfor step display but was never decoded to extract token addresses. When the command loop encountered a V4 swap, it skipped it entirely. SinceinputTokenandoutputTokenremainednull,tokenInfo(null)returned{ symbol: "ETH" }for both.Fix: Added
decodeV4Swap()insrc/shared/uniswap.jswhich parses the V4 inner action bytes:These addresses are resolved via
TOKEN_BY_ADDRESS(the 511-token list) to display correct symbols.make checkpasses: 14/14 tests, lint clean.please add a test that fails before this change and passes after it.

merge-ready, assigned to @sneak.5cac49e430to3c2d553070Added regression test for the V4 swap ERC20→ERC20 decoder fix.
The new test (
decodes V4_SWAP ERC20→ERC20 tokens via SETTLE/TAKE) constructs a Uniswap V4 USDT→USDC swap with SETTLE/SWAP_EXACT_IN_SINGLE/TAKE sub-actions inside a V4_SWAP command (0x10). It asserts the decoded result showsSwap USDT → USDC.Without
decodeV4Swap(): command 0x10 was opaque — the output token would be unresolvable and the name would not show the correct ERC20 symbols.With the fix: SETTLE/TAKE sub-actions are decoded to extract token addresses, producing the correct

"2.0000 USDT ETH"?
Please check anywhere else this particular display bug might be surfacing.
Fix: Double symbol display on tx broadcast status views
Root cause:
decodeCalldata()inapproval.jswas embedding the token symbol into the Amount value string (e.g."2.0000 USDT"). This was then assigned topendingTxDetails.amount. WhentxStatus.jsrendered the waiting/success/error views, it appended the symbol again, producing"2.0000 USDT ETH"(ETH because the token wasn't inTOKEN_BY_ADDRESS, sotxInfo.tokenstayed"ETH").Fix: Added
rawValuefield (numeric only, no symbol) to decoded Amount details.pendingTxDetails.amountnow usesrawValuewhen available, sotxStatus.jsappends the correct symbol exactly once.Changed:
src/popup/views/approval.jsapprovecalldata decoder: split amount formatting intoamountRaw(numeric) andamountStr(with symbol for display)transfercalldata decoder: same splitpendingTxDetails.amountassignment: usesd.rawValue || d.valueAudit of all other amount+symbol display sites:
txStatus.jsshowWait/showSuccess/showError — derives symbol fromtxInfo.token, no duplication ✅confirmTx.jsshow() — builds symbol independently, amount is raw ✅send.js— amount is raw user input ✅addressToken.js— usesbalanceLinehelper ✅transactions.jsparseTx/parseTokenTransfer — separate value/symbol fields ✅No other instances of this bug pattern found.
make checkpasses (15 tests, lint clean).Fix: "2.0000 USDT ETH" double-symbol bug on tx broadcast/status views
Root cause: For Uniswap swaps,
pendingTxDetailswas built with:amount="2.0000 USDT"(from decoded calldata, which includes the symbol)token="ETH"(because thetoaddress is the router, not an ERC20)The tx status view then displayed
amount + " " + symbol→"2.0000 USDT ETH".Fix (two parts):
rawValue(numeric-only, e.g."2.0000") to the Amount detail object, matching the pattern already used by ERC-20 transfer/approve decodersToken Inaddress from decoded details to setpendingTxDetails.tokenandtokenSymbolcorrectly for swaps through router contractsThe existing
d.rawValue || d.valueextraction now gets the clean numeric value, and the symbol comes fromtokenSymbolinstead of being baked into the amount string.Audited other locations:
confirmTx.jsline 131 also concatenatesamount + symbolbut only for direct sends where token info is always set correctly. No other occurrences of this pattern.docker build .passes. 15/15 tests pass.
