📝 WalkthroughWalkthroughThe pull request adds EIP-712 transaction signing and extends exchange v2 with native swap configuration, RFQ liquidation support, cross-margin validation, new queries and events, stricter action parsing, and additional safety bounds. ChangesEIP-712 signing
Exchange v2 extensions
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🔵 Low · up to The PR updates exchange types and validation for RFQ router sets and signing support. A localized rounding-rule mismatch in representability checks does not currently change validation outcomes, but should be aligned or documented; the PR is otherwise mergeable with explicit owner awareness.

87-106: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low valueTwo hand-rolled
LegacyDecproducts round differently fromLegacyDec.Mul. Both sites divide a 10^36-scaled product by 10^18 using round-half-to-even (increment when the remainder exceeds half precision, or equals it and the low bit is set).cosmossdk.io/math.LegacyDec.MuluseschopPrecisionAndRound, which rounds half away from zero and increments whenever the remainder reaches half precision. Both sites feed representability checks only, so the 1-ulp difference does not change any current verdict. Align the rounding or record the deliberate difference so a later caller does not treat these results asLegacyDec.Mulequivalents.

Move the mid-price comment to SpotMidPriceAndTOB.
The comment at Line 170 now applies to SpotSwapOutput. Generated API documentation will describe the swap projection as a mid-price query. Place the comment immediately before SpotMidPriceAndTOB.

Integration note
Open PR #370 uses tag 15 for a separate, undeployed IC-990 field and is not an ancestor of IC-1087. It must rebase after this change and move that field to a new unused tag before merge. This PR retains tag 15 for the approved RFQ router wire contract.
