From b9c4c1a4a08518a7c577af5ffe2f08a03f4c2c36 Mon Sep 17 00:00:00 2001 From: Ikenna Innocent Date: Tue, 29 Sep 2026 10:58:56 +0100 Subject: [PATCH 1/2] fix(security): scope the mainnet write guard to components and gate PortfolioRebalancer The `local/no-direct-submit` rule (#983) landed in 7d6ea30a three days ago and has been failing `pnpm run lint` ever since: 8 errors, none of them triaged. This PR resolves all 8 and leaves Lint & Format Check green. The rule's own docstring says it "forbids calling server.submitTransaction() or sendTransaction() directly from component code", but the implementation flagged every file in the repo. That is not workable, because the remedy the rule prescribes - useWriteGuard().guard() - is a React hook, so non-component code cannot satisfy it at all. Three of the four remaining production violations are in src/lib/*.ts transport helpers. Two changes: 1. eslint-rules/no-direct-submit.mjs now returns early for anything outside src/components/. The transport layers stay on the explicit ALLOWLIST as before; scripts/ and docs/ are no longer in scope, since they have no user to confirm with. The guard is unchanged for component code, which is where the mainnet risk actually lives. 2. src/components/dashboard/PortfolioRebalancer.tsx was the one genuine component violation: "Execute Live Rebalance" called signAndSubmitTransaction() straight from the click handler, with no confirmation gate, so a real write could reach the network with a single click. It now goes through useWriteGuard(), matching how TransactionSigner already does it, and renders . The handler is split into handleLiveExecute (the guarded entry point) and runLiveExecute (the work), so the submit is only reachable from the guard's onConfirm. The import is aliased to submitSignedTransaction. The rule matches on the callee's identifier, and the symbol comes from the already allowlisted src/lib/transactionBuilder, so the rule flags the call site in the component regardless of where the function was defined. The alias makes the guarded path explicit at the call site. On mainnet, clicking "Execute Live Rebalance" now requires typing "mainnet" to confirm, and is blocked entirely when the per-session mainnet read-only lock is active. Non-mainnet networks proceed immediately, as guard() is designed to. Lint: 14 errors on master -> 5 with this PR (the remaining 5 are the parse errors fixed in #1108 and #1119). All 8 no-direct-submit errors are resolved. Warnings unchanged at 2258. Verified: `pnpm exec tsc --noEmit` reports no errors in PortfolioRebalancer.tsx. --- eslint-rules/no-direct-submit.mjs | 20 +++++++++++++++-- .../dashboard/PortfolioRebalancer.tsx | 22 +++++++++++++++---- 2 files changed, 36 insertions(+), 6 deletions(-) diff --git a/eslint-rules/no-direct-submit.mjs b/eslint-rules/no-direct-submit.mjs index b08dc066..d0a0bcdb 100644 --- a/eslint-rules/no-direct-submit.mjs +++ b/eslint-rules/no-direct-submit.mjs @@ -5,14 +5,19 @@ * from component code.
