MGO — Multi-chain Gas Optimizer#

Use this skill when the agent needs to find the cheapest EVM chain for a transaction, compare gas prices across chains, or optimize transaction costs.

When to use#

• "Which chain is cheapest for gas right now?"
• "Compare gas prices across EVM chains"
• "I want to send a transaction — where should I do it?"
• "Find the cheapest chain to deploy a contract"
• "How much will this transaction cost on Base vs Ethereum?"
