gas.estimate
ActiveTool of Syenite
Returns current gas prices and estimated costs for common DeFi operations across EVM chains (Ethereum, Arbitrum, Base, BNB Chain) and Solana priority fees, allowing agents to confirm a wallet holds sufficient native gas and to select the cheapest chain for an operation. Covered operations: transfer, erc20_transfer, erc20_approve, swap, bridge, lending_supply, lending_borrow, contract_register — each reported with gas units, cost in native token, and approximate USD cost at current price. For Solana, returns recent prioritization fees in micro-lamports per compute unit (min, median, p75, max) sampled from the last few slots. Optionally filter by chains (array) and operations (array of operation names); defaults to all chains and all operations. Identifies the cheapest chain per operation. USD estimates use approximate native token prices and are indicative, not exact.
