When tokenBalances doesn't contain an entry for a token (e.g. before
balances are fetched), the symbol fell back to '?' in addressToken
and send views.
Add resolveSymbol() helper that checks tokenBalances → TOKEN_BY_ADDRESS
(known tokens) → trackedTokens → truncated address as last resort.
Fixes USDC and other known tokens showing '?' when balance data
hasn't loaded yet.
Extends the fallback chain to: tb → state.trackedTokens → TOKEN_BY_ADDRESS → '?'
This ensures user-added custom tokens (not just hardcoded known tokens)
display correct symbol, name, and decimals even when Blockscout hasn't
returned balance data (e.g. zero-balance tracked tokens).
When a token's balance entry is missing or incomplete (e.g. not yet
fetched from Blockscout), the address-token view and send view now
fall back to the built-in known token list for symbol, name, and
decimals instead of showing '?'.
Also includes token name in the balance object returned by
fetchTokenBalances so the contract info well can display it.
Fixes#51
- send.js: show addressTitle() above ENS name and address in From field
- txStatus.js: show addressTitle() in To address when it's a local wallet
- home.js: show addressTitle() for counterparties in tx list when they
are local wallet addresses
Delete src/shared/tokens.js and migrate all consumers to
src/shared/tokenList.js which has 511 tokens (vs ~150) sourced
from CoinGecko with on-chain verified decimals.
- prices.js: getTopTokenPrices now from tokenList
- transactions.js: KNOWN_SYMBOLS now from tokenList (3.4x more
symbols for spoof detection)
- send.js: KNOWN_SYMBOLS for token dropdown filtering
- approval.js: uses pre-built TOKEN_BY_ADDRESS map instead of
constructing its own from TOKENS array
- addToken.js: uses getTopTokens(25) for quick-pick buttons
(only top 25 shown, not all 511)
Receive view: address now shows color dot and etherscan link,
matching every other address display in the app.
Send view "From": address now includes etherscan link alongside
the existing color dot.
Send view "What to send" (ERC-20 from token view): shows token
symbol as bold heading, then full contract address below with
color dot, copy-on-click, and etherscan link.
Approval views: tx approval From/To addresses now show color
dots and etherscan links instead of bare text. Site approval
address adds etherscan link. Tx approval value uses 4 decimal
places consistent with all other amount displays.
Home tx list: row padding changed from py-1 to py-2, matching
addressDetail and addressToken transaction lists.
The confirmation page now shows:
- Transaction type (Native ETH transfer vs ERC-20 token transfer)
- Full ERC-20 token contract address with etherscan link
- Token symbol throughout (not raw contract address)
- Current balance of the token being sent, with USD value
- Estimated network fee in ETH and USD (fetched async)
- USD value for ERC-20 token amounts (not just ETH)
- Insufficient balance errors for ERC-20 tokens
Also implements actual ERC-20 token transfers via the token contract's
transfer() function, rather than only supporting native ETH sends.
Read token from state.selectedToken when set, falling back to the
select element. This ensures the correct token balance is shown even
when the select dropdown is hidden or its value didn't take because
the token was filtered out by renderSendTokenSelect.
When sending from the address-token view, show the token symbol as
plain text instead of a disabled dropdown. ERC-20 tokens include an
etherscan link to the contract address. The dropdown is restored when
navigating back or entering send from other views.
Clicking a token balance on the address detail view navigates to a
focused view showing only that token's transactions. Send pre-selects
and locks the token dropdown, Receive shows an ERC-20 warning for
non-ETH tokens, and all back buttons return to the correct parent view.
Three layers of defense against address poisoning attacks:
1. Known symbol verification: tokens claiming a symbol from the
hardcoded top-250 list (e.g. "ETH", "USDT") but from an
unrecognized contract are identified as spoofs and always hidden.
Their contract addresses are auto-added to the fraud blocklist.
2. Low-holder filtering: tokens with <1000 holders are hidden from
both transaction history and the send token selector. Controlled
by the "Hide tokens with fewer than 1,000 holders" setting.
3. Fraud contract blocklist: a persistent local list of detected
fraud contract addresses. Transactions involving these contracts
are hidden. Controlled by the "Hide transactions from detected
fraud contracts" setting.
Both settings default to on and can be disabled in Settings.
Fetching and filtering are separated: fetchRecentTransactions returns
raw data, filterTransactions is a pure function applying heuristics.
Token holder counts are now passed through from the Blockscout API.
Move renderSendTokenSelect to send.js so both the main view and
address detail view call it before navigating to send. Without it,
the token dropdown was stale and updateSendBalance had no context.
Major changes:
- Fetch token balances and tx history from Blockscout API (configurable)
- Remove manual token discovery (discoverTokens) in favor of Blockscout
- HD address gap scanning on mnemonic import
- Duplicate mnemonic detection on wallet add
- EIP-6963 multi-wallet discovery + selectedAddress updates in inpage
- Two-tier balance refresh: 10s while popup open, 60s background
- Fix $0.00 flash before prices load (return null when no prices)
- No-layout-shift: min-height on total value element
- Aligned balance columns (42ch address width, consistent USD column)
- All errors use flash messages instead of off-screen error divs
- Settings gear in global title bar, add-wallet moved to settings pane
- Settings wells with light grey background, configurable Blockscout URL
- Consistent "< Back" buttons top-left on all views
- Address titles (Address 1.1, 1.2, etc.) on main and detail views
- Send view shows current balance of selected asset
- Clickable affordance policy added to README
- Shortened mnemonic backup warning
- Fix broken background script constant imports
