Optimizing Gas Fees for Active Yield Farming on Ethereum

Hey fellow farmers, I've been noticing a significant chunk of my potential gains getting eaten up by gas fees lately, especially when I'm actively rebalancing or harvesting across multiple protocols on Ethereum. It's getting to the point where a small harvest might not even cover the transaction cost!

I'm looking for strategies beyond just 'wait for low gas hours' (though that's definitely part of it). Has anyone found effective ways to optimize their gas spending when farming actively? I'm talking about things like:

• Batching transactions: Are there specific tools or methods you use to group multiple actions into a single transaction?
• Choosing the right network: While Ethereum is the main hub, are you finding better value on L2s like Arbitrum or Optimism for certain farming activities? If so, which ones are most robust for yield farming?
• Gas estimation tools: Beyond Metamask's default, are there any advanced gas trackers or predictors that have proven more accurate for farming actions?
• Smart contract efficiency: Are there specific protocols or vaults known for being more gas-efficient than others when interacting with them?

I'm particularly interested in hearing about experiences with DeFi protocols that have a high volume of smaller transactions, like certain automated vaults or micro-yield aggregators. Any insights on how to minimize slippage and gas costs simultaneously would be super valuable. Let's discuss how to keep more of our hard-earned yield!

From my experience, one of the biggest game-changers has been batching transactions. Instead of executing each action (harvest, rebalance, deposit) as a separate transaction, I try to group as many as possible into a single one, especially when interacting with the same contract or protocol. It's not always feasible, but when it is, the savings can be substantial.

Also, I've been experimenting with L2 solutions like Arbitrum and Optimism for certain farms. The gas fees there are ridiculously lower, and while there's a bridge involved, for frequent, smaller transactions, it often ends up being more cost-effective overall.

Are you guys looking into any specific L2s or using any tools to help with transaction batching? Curious to hear what's working for others.
