Vendor the MetaMask eth-phishing-detect config.json (231k domains) into
src/data/phishing-domains.json as the baseline blocklist shipped with
the extension.
On 24h refresh, only the delta (new domains not in the vendored snapshot)
is kept in memory. Domain checks hit the in-memory delta first (fresh
scam sites), then binary-search the vendored sorted array.
If the delta is under 256 KiB it is persisted to chrome.storage.local
so it survives service-worker restarts without re-fetching.
Removes the previous approach of downloading and holding the full
blocklist in memory as a Set.
- Add etherscanLabels module: scrapes Etherscan address pages for
phishing/scam labels (Fake_Phishing*, Exploiter, scam warnings).
Integrated as best-effort async check in addressWarnings.
- Add phishingDomains module: fetches MetaMask's eth-phishing-detect
blocklist (~231K domains) at runtime, caches in memory, refreshes
every 24h. Checks hostnames with subdomain matching and whitelist
overrides.
- Integrate domain phishing checks into all approval flows:
connection requests, transaction approvals, and signature requests
show a prominent red warning banner when the requesting site is on
the MetaMask blocklist.
- Add unit tests for both modules (12 tests for etherscanLabels
parsing, 15 tests for phishingDomains matching).
Closes#114
Adds a test that constructs a Uniswap V4 USDT→USDC swap using
SETTLE/SWAP_EXACT_IN_SINGLE/TAKE sub-actions inside a V4_SWAP command.
Without decodeV4Swap(), the output token would be unresolvable and the
swap name would not show 'USDT → USDC'. This test fails on the old code
and passes with the decodeV4Swap() fix.
Refs: #59
Replace stub error handlers with full approval flow for personal_sign,
eth_sign, eth_signTypedData_v4, and eth_signTypedData. Uses toolbar
popup only (no fallback window) and keeps sign approvals pending across
popup close/reopen cycles so the user can respond via the toolbar icon.
Makefile, Dockerfile, CI workflow, prettier config, manifests for
Chrome (MV3) and Firefox (MV2), source directory structure, and
minimal test suite. All checks pass.
