add LZ infra, chain IDs, hops, monad, stable constants for frax-lz-mesh

Copilot

Pull request overview

This PR expands the scripts/constants/* network constant modules to include LayerZero infra addresses (endpoint + libs + block send lib + proxy admin) and adds LayerZero chain IDs + EVM chain IDs for additional networks in support of the frax-lz-mesh tooling.

Changes:

Add LayerZeroInfra constants and LZ_CHAIN_ID / CHAIN_ID entries across many existing network constant files.
Add new constants modules for stable and monad, and export them from scripts/constants/index.ts.
Update/normalize a few existing constants (e.g., Scroll OFT addresses; Solana semicolons) while adding the new infra constants.

scripts/generateConstants.ts relies on networkPrefixes[networkName] to build label strings, but this PR adds new exported networks (e.g., Monad/Movement/Stable) that do not exist in the networkPrefixes map. When npm run generate:constants runs, these will produce labels like Constants.undefined_<KEY>, and some existing entries also appear to differ in casing (e.g., Base vs BASE, ZkSync vs Zksync), which has the same effect. Consider updating networkPrefixes to include the new exports and align key casing with the names exported from this index file, or make the generator fall back to networkName when no prefix exists.

These new Solana LayerZero infra values are non-0x strings (base58). scripts/generateConstants.ts currently emits vm.label(${value}, ...) without quotes for every non-number constant, which will generate invalid Solidity for these entries (e.g., vm.label(76y77..., ...)). Consider updating the generator to only label EVM address-shaped values (e.g., 0x + 40 hex chars) or skipping labeling for Solana/string constants.

These newly added LayerZero infra constants are 0x-prefixed 32-byte hex strings (not 20-byte EVM addresses). scripts/generateConstants.ts currently treats any 0x... string as a Solidity address literal and also passes it to vm.label(...), which will cause the generated Solidity to fail to compile for Aptos. Consider tightening the generator’s address detection (e.g., require 20-byte length) and emitting bytes32/string for non-address hex values, or excluding non-EVM networks from Solidity constant generation.

+  BLAST: "BLAST",
+  BSC: "BSC",


networkPrefixes keys don't match the actual exported network names from scripts/constants/index (e.g., constants exposes Base, Bera, Blast, ZkSync, but this map uses BASE, BERA, BLAST, Zksync). This causes networkPrefixes[networkName] to be undefined for those networks, producing mislabeled constants in the generated Solidity. Align the keys with the module export names (or normalize networkName before lookup / provide a fallback).

+        }

+        numberValues.push(value);
+        return `    uint256 internal constant ${key} = ${value};`;
+      }


Address detection is currently value.startsWith("0x"), which will misclassify non-address hex strings (e.g., 32-byte IDs in Aptos/Movement constants) as address and generate invalid Solidity literals. Consider validating EVM addresses by length/hex (0x + 40 hex chars) and handling other hex strings as bytes32/bytes/string as appropriate.

+      // Return the string
+      return `        vm.label(${value}, "Constants.${networkPrefixes[networkName]}_${key}");`;
+    })


vm.label(${value}, ...) assumes value is an address literal. For constants that are plain strings (e.g., Solana base58 IDs) this will emit invalid Solidity (unquoted identifiers) and fail compilation. Restrict labeling to verified EVM address constants (and skip labeling for non-address types).

CHAIN_ID was removed from this TS constants module, but other network modules (and the existing fraxtal-l2.js) export it. This creates an inconsistent API surface for FraxtalL2 and can break TypeScript consumers expecting CHAIN_ID. Re-add export const CHAIN_ID = 252; (or remove it everywhere consistently) and regenerate any derived JS if applicable.

- Add REMOTEHOPV2 + REMOTEADMINV2 to spoke chain constants - Add FRAXTALHOPV2 to fraxtal-l2 constants - Add HOP_V2_ABI.json with all HopV2 view functions + AccessControlEnumerable - Update abis index to export HOP_V2_ABI - Includes compiled JS output
