To support additional chains (say Polygon, Optimism, etc.):

• Deploy a TokenFactory on those chains (as in Section 6).

• Add their LayerZero chain IDs and endpoint addresses to the code (LayerZero supports many chains; check docs for the chain ID and endpoint address).

• Update the

  setPeer

  configuration to include the new chain for all existing ones and vice versa.

• Ensure there is a UniswapV2-like DEX available. On Polygon, you might use QuickSwap (Uni v2 addresses), on Optimism perhaps SushiSwap or deploy your own.

• If using testnets or other LayerZero-supported environments, you can do the same (just different endpoints and chain IDs for testnet).

The system is not inherently limited to the five chains; those were just initial examples. LayerZero v2 can connect dozens of chains, so as long as you update the mappings and have a DEX, you can extend it.
