Blocknative provides real-time mempool monitoring and transaction management tools for public blockchains.
Tools
Configure Mempool Filters
Tool to configure filters and ABI decoding for Ethereum mempool transactions. Use after establishing a Blocknative WebSocket connection to set up event filters and decoding.
Get Gas Price Distribution
Tool to retrieve the current mempool gas price distribution breakdown. Use when analyzing gas price trends or preparing fee strategies.
Get Gas Oracles
Tool to retrieve metadata on supported gas oracles per chain. Use when you need to dynamically discover all available on-chain gas estimation oracles across networks.
Get Gas Prices
Tool to fetch gas price estimates for specific inclusion probabilities. Use when you need gas price ranges for the next block or next ~10 seconds.
Get Supported Chains
Tool to retrieve supported chains metadata. Use when discovering available networks for Blocknative gas services.
Get Base Fee Estimates
Get real-time gas fee predictions for Ethereum mainnet's next 5 blocks. Returns base fee, blob base fee, and priority fee estimates at multiple confidence levels (99% and 50%). Essential for optimizing transaction costs and timing. Predictions include current block context (block number, time since last block) and estimated fees in gwei.
