Blocknative MCP integration
Quotes next-block gas and base fee predictions, prepares mempool and transaction subscriptions, and cleans them up when monitoring ends.
10actions available
Three actions you can hand over today
Every action runs live through MCP. Nothing to build, nothing to maintain.
Get gas prices
Lyro fetches real-time gas price estimates from Blocknative for specific transaction priorities. Your team decides when to execute blockchain operations based on current costs.
Subscribe transaction hash
Lyro sets up event subscriptions for an Ethereum transaction hash via Blocknative. Your team monitors critical transactions and reacts instantly when status changes.
Unsubscribe transaction hash
Lyro cancels event subscriptions for a transaction hash to clean up monitoring overhead. You stop tracking stale transactions and reduce unnecessary notifications.
How businesses use Blocknative + Lyro
Each card is one request a support team gets, and the Blocknative actions Lyro runs to close it.
Price a transaction before it is sent
Lyro returns gas prices for the next block or roughly the next ten seconds, base, blob and priority fee predictions for Ethereum's next five blocks, and the mempool distribution those numbers came from.
Get Gas PricesGet Base Fee EstimatesGet Gas Price DistributionWatch a transaction until it settles
Lyro composes the subscription payload for a transaction hash or an account address on any supported chain and sets the mempool filters and ABI decoding, so state changes arrive decoded as they happen.
Subscribe Transaction HashSubscribe MultichainConfigure Mempool FiltersRetire a watch once monitoring is done
Lyro cancels a transaction-hash subscription or removes a multichain watch by its id and chainId, so a long-running session does not leave dead subscriptions consuming the connection.
Unsubscribe Transaction HashUnsubscribe MultichainCheck coverage before building on a network
Lyro lists the chains Blocknative's gas services support and the on-chain gas estimation oracles available on each, so a question about a less common network is settled up front.

How it works
Get started in 3 steps
Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Lyro reads the Blocknative actions it has and picks the ones a request needs.
Connect Blocknative
Authorize the Blocknative account your team already uses — one consent screen, no API keys, no mapping tables. Lyro can only do what you granted that account, and you can disconnect it at any time.
Tell your agent what you need
Describe the job the way you would hand it to a teammate. Lyro maps it to the Blocknative actions that close it and chains as many as the request needs.
Watch it work
The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.

FAQ
Everything else about Blocknative
Setup, permissions, and the limits of what Lyro can do inside Blocknative.
No. Subscribe Transaction Hash and Subscribe Multichain return the connection details and the subscription message to send; the socket itself is opened by a WebSocket client on your side. Lyro's part is composing the correct payload for the chain and target, and calling the matching unsubscribe when the watch is finished.
