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.
Tool to retrieve the current mempool gas price distribution breakdown. Use when analyzing gas price trends or preparing fee strategies.
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.
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.
Tool to retrieve supported chains metadata. Use when discovering available networks for Blocknative gas services.
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.

Subscribe Multichain
Generate WebSocket connection details to subscribe to real-time blockchain events (transactions or account activity) across multiple chains via Blocknative's Multichain API. Returns the WebSocket URL and subscription message payload needed to establish the connection and start receiving event notifications for a specific transaction hash or account address on any supported blockchain.
Subscribe Transaction Hash
Tool to subscribe to transaction state change events of an Ethereum transaction hash. Use after establishing a Blocknative WebSocket connection to prepare the subscription message.
Unsubscribe Multichain
Tool to unsubscribe from events across multiple chains using the Multichain SDK. Use after stopping monitoring of an address or transaction to clean up resources, e.g., call: blocknative.unsubscribe({ id: '0x..', chainId: '0x1' }).
Unsubscribe Transaction Hash
Tool to unsubscribe from transaction state change events for an Ethereum transaction hash. Use after establishing a Blocknative WebSocket connection to prepare the unsubscription message.
