Approved, but curious do we need to hardcode these ones? we probably get TVL anyway from the subgraph right?

The log message contains an incorrect pool name. It refers to "flETH/FLNCH pool" but this code section is handling the MAINNET WETH/ETH pool as indicated by the comment on line 53. The message should be updated to:

log.debug(`Setting tvl for MAINNET WETH/ETH pool ${JSON.stringify(pool)}`)

This will ensure the logging accurately reflects which pool is being processed.

Suggested change

	log.debug(`Setting tvl for flETH/FLNCH pool ${JSON.stringify(pool)}`)
	log.debug(`Setting tvl for MAINNET WETH/ETH pool ${JSON.stringify(pool)}`)

Thanks for the review, @cgkol - WETH is not working rn and I'm debugging and splitting the WETH and the WstETH PRs since:

1. WETH requires more debugging from our side
2. WstETH is blocked by the protocol team

I will debug more from here

We do need to inflate ETH/WETH hooked pool because 0 TVL pool will not get picked up by SOR during get-candidate-pools. @cgkol

However as @yucanliu indicated, merely inflating ETH/WETH is not sufficient to make this hooked pool routing work somehow. More debugging needed. Hoping to see more progress being made, but also happy to help.

There's a discrepancy in the TVL USD value for the Arbitrum ETH/WETH pool. In addWethPools(), the value is set to 60342168, but in v4HooksPoolsFiltering.ts, it's set to 41820637. These values should be consistent to ensure proper behavior. Consider updating one of these values to match the other, preferably using the most current data from the referenced pool.

Suggested change

	tvlUSD: 60342168,
	tvlUSD: 41820637,

We decided to close this one and split into 5 for each chain:
#1137: MAINNET
#1136: BASE
#1135: OPTIMISM
#1134: UNICHAIN
#1133: ARBITRUM_ONE
