How To Add Routable Platforms

For UniV2 Forks

First, open the file UniswapV2RoutablePlatform.ts. Here, you'll find several examples of already integrated DEXs.

Next, you need to search for the following information about the platform you want to integrate:

Supported chains by the DEX.
Factory Address: You can find it in the protocol docs.
Router Address: You can find it in the protocol docs.
Init Code Hash: Looking at the Factory Address in a blockchain explorer, you can go to the Contract tab > Read Contract > INIT_CODE_HASH.
Default Swap Fee: You may find it in the protocol official docs or in the Factory Address code.
Subgraph Endpoint (optional).

Once you have this information, you can create an instance of UniswapV2RoutablePlatform for the DEX you're trying to integrate and then consume it from the file entities/pair.ts so you can add it to the PAIR_ADDRESS_CACHE.
