ITS-131 Promote monad integration to mainnet

[joaoazevedo]

Note

Adds Monad mainnet/testnet support across chain configs and clients, and upgrades viem to 2.40.0.

• Chains:
  • Add monad (mainnet) and monadTestnet (testnet) to apps/maestro/src/config/chains/evm-chains.ts with RPC configs, Axelar IDs, and environments.
  • Register monad in MAINNET_CHAINS and monad (testnet) in TESTNET_CHAINS within packages/evm clients.
• Dependencies:
  • Upgrade viem to ^2.40.0 in apps/maestro/package.json and packages/evm/package.json with corresponding lockfile and peer updates (e.g., wagmi, web3 modal connectors).

Greptile Overview

Greptile Summary

This PR promotes monad blockchain integration from testnet to mainnet by adding monad chain configurations across the codebase.

Key Changes:

• Upgraded viem from ^2.30.1 to ^2.40.0 in both apps/maestro and packages/evm to gain access to monad chain definitions
• Added monad and monadTestnet imports from viem/chains
• Configured monad mainnet and testnet chains in evm-chains.ts with proper RPC URLs, Axelar chain IDs, and environment settings
• Exported monad in MAINNET_CHAINS and monadTestnet (as 'monad') in TESTNET_CHAINS for client creation support

The implementation follows the established pattern for adding new chain support, with consistent configuration across mainnet and testnet environments.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The changes are straightforward and follow established patterns for adding new chain support. The viem version bump is necessary to access monad chain definitions, and all configurations are consistent across mainnet/testnet environments. No logic changes or custom implementations - purely additive configuration.
• No files require special attention
