The practical details behind the request, access and result.
How can the Gas Fee Estimator help me save money on crypto?
It provides real-time data on gas prices and priority fees so you don't overpay. By knowing the exact cost before you send a transaction, you can avoid wasting native tokens on high fees.
Can I use Gas Fee Estimator to see costs in USD?
Yes, the Connector can convert native token costs into fiat values like USD. This helps you understand the actual dollar amount of a transaction without having to do manual math.
Does Gas Fee Estimator work for all blockchains?
It is specifically designed for EVM-compatible networks like Ethereum, Polygon, and various Layer 2 solutions. It won't work for non-EVM chains like Bitcoin or Solana.
How does Gas Fee Estimator help with stuck transactions?
It suggests the correct priority fee based on recent network activity. By using these recommendations, you can ensure your transaction is picked up by the network quickly.
Can Gas Fee Estimator compare different Layer 2 networks?
Yes, you can ask your agent to compare costs across multiple chains at once. It will show you a side-by-side view to help you choose the cheapest network for your move.
Is Gas Fee Estimator accurate for EIP-1559 networks?
It is built to handle EIP-1559 fees, which are standard on Ethereum. It calculates the base fee and priority fee to give you an accurate total cost.
How can I calculate the total cost of an Ethereum transaction?
You can use the calculate_gas_cost capability by providing the gas limit, base fee, and priority fee.
How do I know what priority fee to set for a fast transaction?
The recommend_priority_fee capability analyzes recent network activity to suggest the best tip for 'slow', 'standard', or 'fast' tiers.
Can I compare costs between Polygon and Ethereum?
Yes, the compare_chain_costs capability allows you to input estimates for multiple chains and see a side-by-side comparison.
