Verified token discovery and dashboard display lib/kcc20/index.ts, lib/kcc20/useKcc20Tokens.ts, components/dashboard/Assets.tsx, components/dashboard/TokenListItem.tsx, hooks/useFeatureFlags.ts, tests/kcc20-unit.spec.ts |
The hook fetches mainnet holdings. Discovery verifies wallet ownership, live outpoints, balances, and registry metadata. The dashboard displays eligible tokens and links to the send route when the feature is enabled and the wallet is not Ledger. |
KCC-20 transfer construction and send flow lib/kcc20/transfer.ts, components/send/kcc20-send/Kcc20Send.tsx, entrypoints/popup/router.tsx, tests/kcc20-transfer-unit.spec.ts |
The transfer code validates recipients, selects token pieces, funds covenant spends, signs funding inputs, and submits transactions. The routed send screen provides details, confirmation, success, and failure states. |
Reusable KCC-20 token interface components ui/popup/kcc20/*, tailwind.config.js |
The components render token images, network chips, token items, token details, selection, and send confirmation. Storybook stories cover their variants and states. |
KRON curve swaps
| Layer / File(s) | Summary |
|---|---|
Market discovery, curve state, and fee quotes lib/kcc20/swap.ts, package.json, tests/kcc20-swap-unit.spec.ts |
The library discovers eligible markets, loads curve state, and calculates fee-adjusted buy and sell quotes. |
Swap construction and submission lib/kcc20/swap.ts, tests/kcc20-swap-unit.spec.ts, wxt.config.ts |
The builder creates buy or sell covenant spends with slippage and funding checks. Submission reconciles sequencer and node status before retrying, rebuilding, or submitting directly. The extension declares the sequencer host permission. |
Swap screen integration and validation components/screens/Swap.tsx, hooks/useAnalytics.ts |
The Swap screen adds KRON markets and KAS, validates supported pairs, input precision, and balances, and displays KRON-specific quotes and fees. Analytics accepts "l1" as a Kaspa L1 chain ID. |
dApp signing guard
| Layer / File(s) | Summary |
|---|---|
Reject unsupported covenant transactions api/background/handlers/kaspa/utils.ts, api/background/handlers/kaspa/signTx.ts, api/background/handlers/kaspa/signAndBroadcastTx.ts, api/message.ts, tests/signtx-unit.spec.ts |
The signing handlers reject malformed or non-version-0 transaction JSON before opening the signing popup. They return the unsupported-covenant RPC error. |

Merge Risk: 🟡 Moderate · up to ed2bf
-
A rate-limited or erroring sequencer can cause a swap to be sent straight to the node while other trades are in flight on the curve. The node will likely reject it and the user sees a failed swap. The earlier concern about the send route redirecting before the KCC-20 flag loads is also still open. Both should be addressed before merge.

91-100: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low valueThe greedy loop reports "fragmented" when the balance is enough but needs more than three pieces.
This behavior is correct for the v1 limit. However, the error message asks the user to send a smaller amount without saying what the maximum is. The maximum is the sum of the three largest pieces, and the code can compute it. Include that value in the message so the user can recover.

isOwnedByhides ADDRESS-owned balances held by P2SH wallets, and it counts PUBKEY balances the transfer flow cannot spend.
PUBKEYandADDRESSshare one P2PK comparison, so the dashboard counts PUBKEY-owned pieces inamount.selectPiecesinlib/kcc20/transfer.tsspends onlyADDRESSpieces. The PR lists this as an accepted v1 limit. The result is that the displayed balance can be higher than what the user can send. The send screen then shows a balance that a full-amount send rejects with "insufficient-balance". You could show a separate spendable figure, or document the limit near the balance display.🤖 Prompt for AI Agents

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Classify curveHead failures with isSequencerUnreachable.
.catch(() => undefined) turns every curveHead failure into seq === undefined. Line 338 then sets submitDirect: !seq?.ok, which is true. As a result, an HTTP 429 or 500 from a sequencer that is up builds the trade on the node's confirmed state. At Line 586, submitKronSwap then sends that trade straight to the node with no reconciliation.
This breaks the rule that isSequencerUnreachable and the PR description state: only a network failure means the sequencer is unreachable. An HTTP status means the sequencer answered.
Trigger: the sequencer rate-limits or returns 5xx on curveHead while it holds a chain of trades in flight. The confirmed-state build spends a curve UTXO that the trades in the mempool already spend. The node then rejects the trade, and the user sees a failed swap instead of a queued trade.
Rate limits are most likely when the curve is busiest, so this case is realistic. A call to the existing helper fixes it: a status or decode error should fail the quote, as reconcileCurveTrade already does for curveStatus.

…hable The sweep funded big >= 100M next to a 100M UTXO. The piece re-emits its 50M carrier as two 50M outputs, so one input always left >= ~28M change, above FEE_OUT_MIN (20M); below 100M the 100M UTXO sorted first. The branch that adds an input for sub-minimum change was never exercised. Sweep from 73M, past the ~72.4M one-input threshold (asserted), with a smaller 30M UTXO that sorts second, so a two-input build can only come from the FEE_OUT_MIN branch. Removing that branch now fails the test. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Main's #390 (Node 24) migrated the other specs off module.register(); the async loader no longer intercepts Playwright's import of .png assets, so kcc20-swap-unit and kcc20-transfer-unit (which relies on the same loader) failed to load after the rebase.

… reconciliation, CORS, SDK 0.19.1) Ports cf781ef (fix/kcc20-shawn-review, PR #393) onto feat/kcc20: - @kronsdk/kron-sdk 0.18.2 -> 0.19.1 (curveStatus, retry/ambiguous submit results) - submitKronSwap serializes the signed tx once and resends the identical string on a stale-head 409, so the sequencer dedupes it instead of ordering a second trade - on a second retry or an ambiguous broadcast, reconcile against the sequencer record and the node mempool (assertCurveTradeDead) before a rebuild; a live trade surfaces as the new "processing" error - host_permissions for seq.kron.technology (sequencer CORS is locked to KRON) - tests: serializer round-trip (from cf781ef) plus sequencer-submit resend/reconcile cases and "processing" copy liveCurve keeps this branch's fail-closed handling of a { ok: false } head.

A thrown curveSubmit (network error / dropped connection) left the trade's fate unknown but surfaced as a generic failure, so a retry could rebuild a second trade while the first was already live on the sequencer. Run the same assertCurveTradeDead reconciliation on the throw path: a live trade surfaces as "processing"; only a provably dead one re-throws the original error.

Kcc20SendRoute read the fail-closed KCC-20 flag before PostHog delivered it, so a production user who opened the send route was sent to the dashboard and stayed there.
