## Description
Bumps SDK dependencies in universal-router-sdk and adds X-Layer chain configuration to enable X-Layer support. This follows the recent SDK version bumps (Uniswap#463, Uniswap#464, Uniswap#465, Uniswap#466) that added X-Layer support to the individual SDKs.
## Changes
- Updated `@uniswap/router-sdk` version in `sdks/universal-router-sdk/package.json` from `^2.1.0` to `^2.3.0`
- Updated `@uniswap/sdk-core` version from `^7.8.0` to `^7.10.0`
- Updated `@uniswap/v2-sdk` version from `^4.16.0` to `^4.17.0`
- Updated `@uniswap/v3-sdk` version from `^3.26.0` to `^3.27.0`
- Updated `@uniswap/v4-sdk` version from `^1.23.0` to `^1.24.0`
- Added X-Layer chain configuration (chain ID 196) in `constants.ts` with WETH address and Universal Router addresses for V1_2, V2_0, and V2_1
- Updated `yarn.lock` to reflect the new dependency versions
## How Has This Been Tested?
Will test in routing
## Are there any breaking changes?
No

## Description
Reverts Universal Router 2.1 support that was added in PR Uniswap#442. This PR removes all v2.1-specific features to roll back to a v2.0-only state.
## Changes
- Removed `UniversalRouterVersion.V2_1` enum value and all v2.1 router addresses from chain configurations
- Deleted `src/utils/eip712.ts` (EIP712 signing utilities for signed route execution)
- Deleted `src/entities/actions/across.ts` (Across V4 bridge types)
- Removed `SignedRouteOptions`, `EIP712Payload` types and `getExecuteSignedPayload()`, `encodeExecuteSigned()` methods from `swapRouter.ts`
- Removed `maxHopSlippage` option from `SwapOptions` interface
- Removed `addAcrossBridge()` method and `ACROSS_V4_DEPOSIT_V3` command from `routerCommands.ts`
- Removed exports: `NONCE_SKIP_CHECK`, `generateNonce`, `EXECUTE_SIGNED_TYPES`, `getUniversalRouterDomain`
- Deleted unit tests for signed routes (`signedRoutes.test.ts`) and Across bridge (`across.test.ts`)
- Removed v2.1 documentation from README.md (per-hop slippage, signed routes, cross-chain bridging)
## How Has This Been Tested?
Unit tests updated to remove v2.1-specific test cases.
## Are there any breaking changes?
Yes - removes the following exports and functionality:
- `UniversalRouterVersion.V2_1`
- `SignedRouteOptions`, `EIP712Payload` types
- `NONCE_SKIP_CHECK`, `generateNonce`, `EXECUTE_SIGNED_TYPES`, `getUniversalRouterDomain` exports
- `SwapRouter.getExecuteSignedPayload()` and `SwapRouter.encodeExecuteSigned()` methods
- `AcrossV4DepositV3Params` type and `CONTRACT_BALANCE` from across module
- `maxHopSlippage` option in `SwapOptions`
- Bridge parameters in `SwapRouter.swapCallParameters()`

* feat(router-sdk): add maxHopSlippage to Trade.swaps (Uniswap#529)

## Description

For maxHopSlippage, **a partial implementation exists for multi-hop V4-only routes in UR-sdk, but it is incorrect:**

1. Flat array on **`SwapOptions`** -- A single `maxHopSlippage?: BigNumber[]` on `SwapOptions` cannot correctly map values to specific routes in a split-route trade (e.g. 40% Route A with 3 hops, 60% Route B with 2 hops).
2. Mixed routes pass the full array -- In `addMixedSwap`, the entire `options.maxHopSlippage` array is passed to V4 sections without slicing; V2/V3 sections get nothing.



**We need to ensure that per-hop slippage is saved per** **_route_** **data model, not per** **_trade_** **(i.e. for split route trades)**

**This PR adds** `maxHopSlippage` **support to the** `Trade.swaps` **object in router-sdk, enabling per-hop slippage protection for multi-hop swaps across all route types (V2, V3, V4, and mixed routes)**

## How Has This Been Tested?

_[e.g. Manually, E2E tests, unit tests, Storybook]_

## Are there any breaking changes?


Purely additive, no breaking changes, no existing code uses the new field yet. Can merge independently.

## Follow Ups

- in order to be used in UR-sdk, need to publish minor version bump to router-sdk

## Summary

Adds `maxHopSlippage` support to the `Trade` class in router-sdk, enabling per-hop slippage protection for multi-hop swaps across all route types (V2, V3, V4, and mixed routes).

## Changes

- Added optional `maxHopSlippage?: bigint[]` field to the `swaps` array type in `Trade` class
- Extended route input types for V2, V3, V4, and mixed routes to accept `maxHopSlippage` parameter
- Propagated `maxHopSlippage` through the constructor for all route types
- Extended `fromRoutes()` static method to pass `maxHopSlippage` through populated routes

## How Has This Been Tested?

This is a type extension.

## Are there any breaking changes?

No - `maxHopSlippage` is an optional parameter with no changes to existing behavior.

* feat(breaking): switch v4-sdk from UR v2.1 to UR v2.1.1 & add single-hop ABI struct (Uniswap#530)

## Description

- Rename URVersion.V2_1 to `V2_1_1 `in v4-sdk
- Rename V4_SWAP_ACTIONS_V2_1 to `V4_SWAP_ACTIONS_V2_1_1` and update all references in v4Planner.ts

## How Has This Been Tested?

_[e.g. Manually, E2E tests, unit tests, Storybook]_

## Are there any breaking changes?

The version rename is breaking. (And it is intentionally breaking, as opposed to keeping v2.1 around, because v2.1.1 fixes a precision bug. Plus we don't actually use v2.1 in prod yet)

1. publish v4-sdk as major version
2. update UR-sdk and router-SDK

## ✨ Claude-Generated Content

## Summary

Updates v4-sdk to use Universal Router version 2.1.1 instead of 2.1 by renaming version enums, ABI definitions, and struct types throughout the codebase. Adds V2.1.1-specific struct definitions for single-hop swap actions.

## Changes

- Renamed `URVersion.V2_1` to `URVersion.V2_1_1` in the `URVersion` enum
- Renamed `V4_SWAP_ACTIONS_V2_1` to `V4_SWAP_ACTIONS_V2_1_1` and expanded to include single-hop swap actions (`SWAP_EXACT_IN_SINGLE`, `SWAP_EXACT_OUT_SINGLE`)
- Added new V2.1.1 struct definitions with `maxHopSlippage` field:
    - `SWAP_EXACT_IN_SINGLE_STRUCT_V2_1_1`
    - `SWAP_EXACT_IN_STRUCT_V2_1_1`
    - `SWAP_EXACT_OUT_SINGLE_STRUCT_V2_1_1`
    - `SWAP_EXACT_OUT_STRUCT_V2_1_1`
- Renamed V2.0 single-hop structs to be explicit: `SWAP_EXACT_IN_SINGLE_STRUCT_V2_0`, `SWAP_EXACT_OUT_SINGLE_STRUCT_V2_0`
- Refactored `addTrade` method to use conditional spread operator for cleaner version-specific struct building
- Added validation that `maxHopSlippage` length matches `route.pools.length`
- Updated `v4BaseActionsParser.ts` to use the new version enum and ABI definitions
- Updated all comments referencing "V2.1" to "V2.1.1"
- Updated all test files to use `URVersion.V2_1_1`

## How Has This Been Tested?

Existing unit tests updated to use the new version constant.

## Are there any breaking changes?

Yes - this is a breaking change for consumers using `URVersion.V2_1` or `V4_SWAP_ACTIONS_V2_1`. They will need to update to `URVersion.V2_1_1` and `V4_SWAP_ACTIONS_V2_1_1` respectively.

* feat(universal-router-sdk): v2.1.1 version rename & ABI structs (Uniswap#531)

## Description



TODO : Need to explicitly update UR-sdk and router-SDK versions based on v4-sdk breaking changes

- Rename UniversalRouterVersion.V2_1 to V2_1_1 in constants.ts + update contract addresses
- Add V2.1.1 ABI definitions for V2/V3 swap commands in routerCommands.ts (the new V2V3_SWAP_COMMANDS_V2_1_1 map)
- Make addCommand/createCommand accept optional urVersion parameter for ABI selection

This is all infrastructure/plumbing. The new V2.1.1 ABI defs exist but nothing calls them yet. The version rename is technically breaking but no consumers use UR V2.1 from the SDK.

## How Has This Been Tested?

_[e.g. Manually, E2E tests, unit tests, Storybook]_

## Are there any breaking changes?

_[e.g. Type definitions, API definitions]_

If there are breaking changes, please ensure you bump the major version Bump the major version (by using the title `feat(breaking): ...`), post a notice in #eng-sdks, and explicitly notify all Uniswap Labs consumers of the SDK.

## ✨ Claude-Generated Content

## Summary

Renames `UniversalRouterVersion.V2_1` to `V2_1_1` and adds ABI infrastructure for V2.1.1 swap commands with `maxHopSlippage` support.

## Changes

- Renamed `UniversalRouterVersion.V2_1` to `V2_1_1` in `constants.ts` enum (version string `'2.1'` → `'2.1.1'`)
- Updated all chain configs (20+ chains) to use `[UniversalRouterVersion.V2_1_1]` key
- Added `V2V3_SWAP_COMMANDS_V2_1_1` ABI definitions for V2/V3 swap commands with extended `maxHopSlippage` parameter:
    - `V3_SWAP_EXACT_IN`
    - `V3_SWAP_EXACT_OUT`
    - `V2_SWAP_EXACT_IN`
    - `V2_SWAP_EXACT_OUT`
- Updated `addCommand()` and `createCommand()` to accept optional `urVersion` parameter for ABI selection
- Fixed comment typo in `Parser.V3Actions` case ("v4 swap data" → "v3 position data")

## How Has This Been Tested?

Infrastructure/plumbing changes only - the new V2.1.1 ABI definitions exist but are not yet called by any code paths.

## Are there any breaking changes?

The version enum rename from `V2_1` to `V2_1_1` is technically breaking, but per the design doc, no consumers currently use V2.1.

- Update Swap interface to carry maxHopSlippage (from trade.swaps)
- addV2Swap / addV3Swap: branch on urVersion to encode with or without maxHopSlippage
- addV4Swap: read maxHopSlippage from swap instead of options
- addMixedSwap: slice maxHopSlippage per section with hop offset tracking
- Tests for all protocol paths (V2, V3, V4, mixed) with and without per-hop slippage

## How Has This Been Tested?

_[e.g. Manually, E2E tests, unit tests, Storybook]_

## Are there any breaking changes?

If consumers want to use UR v2.1.1, they must update to this version of the UR-sdk.

## Summary
Wire up per-hop slippage encoding for Universal Router v2.1.1 across all protocol versions (V2, V3, V4, and mixed routes). The `maxHopSlippage` parameter has been moved from `SwapOptions` to individual swaps, enabling granular slippage protection per route.
## Changes
### `sdks/universal-router-sdk/src/entities/actions/uniswap.ts`
- Removed `maxHopSlippage` from `SwapOptions` interface
- Added `maxHopSlippage?: bigint[]` to the `Swap` interface to carry per-hop slippage from trade.swaps
- `addV2Swap`: branches on `urVersion` to encode with/without `maxHopSlippage` for V2_SWAP_EXACT_IN and V2_SWAP_EXACT_OUT commands
- `addV3Swap`: branches on `urVersion` to encode with/without `maxHopSlippage` for V3_SWAP_EXACT_IN and V3_SWAP_EXACT_OUT commands
- `addV4Swap`: reads `maxHopSlippage` from the swap object instead of options
- `addMixedSwap`: tracks `hopOffset` to slice the flat `maxHopSlippage` array per protocol section
- Added validation to ensure `maxHopSlippage` length matches `route.pools.length`
### `sdks/universal-router-sdk/README.md`
- Updated per-hop slippage documentation to reflect new API where `maxHopSlippage` is specified on each route within `RouterTrade`
- Added mixed routes example showing how the SDK slices hop slippage by section
- Updated references from v2.1 to v2.1.1
### `sdks/universal-router-sdk/test/unit/perHopSlippage.test.ts` (new)
- Tests for V2_SWAP_EXACT_IN/OUT with maxHopSlippage (V2.1.1 ABI)
- Tests for V3_SWAP_EXACT_IN/OUT with maxHopSlippage (V2.1.1 ABI)
- Tests for empty maxHopSlippage arrays
- Backward compatibility tests (V2.0 ABI without maxHopSlippage)
- Mixed route slippage slicing tests
## How Has This Been Tested?
Unit tests covering all protocol paths (V2, V3, V4, mixed) with and without per-hop slippage encoding.
## Are there any breaking changes?
**Minor breaking change**: `maxHopSlippage` has been removed from `SwapOptions`. Consumers must now specify `maxHopSlippage` on individual routes within the `RouterTrade` constructor.
Migration:
```typescript
// Before (v2.1)
SwapRouter.swapCallParameters(trade, { maxHopSlippage: [...], urVersion: URVersion.V2_1 })
// After (v2.1.1)
const trade = new RouterTrade({
  v3Routes: [{ routev3, inputAmount, outputAmount, maxHopSlippage: [...] }],
  tradeType,
})
SwapRouter.swapCallParameters(trade, { urVersion: URVersion.V2_1_1 })
```

## Description

previously we were exporting URVersion from v4-sdk for the `urVersion` field in universal-router-sdk's `SwapOptions`. it's a strange import pattern, and also forces ur-sdk consumers to import v4-sdk just for the typing

we should use UniversalRouterVersion from universal-router-sdk.
