# Analytics tools

> Learn about platforms you can use to gather analytics and set up customizations about OP Mainnet.

The following guide lists platforms you can use to gather analytics and set up customizations about OP Mainnet.

## Blocknative

[Blocknative](https://www.blocknative.com/) lets you [decode](http://docs.blocknative.com/ethernow/batch-decoder-api) and [analyze](https://docs.blocknative.com/blocknative-data-archive/blob-archive) OP Stack Batches submitted to the Ethereum L1. You can inspect, analyze, decode, and download the data of any batch – confirmed on-chain or not – via public APIs or visually through the [Ethernow Explorer](http://ethernow.xyz). Below you can find links to the different resources:

* [Batch Decoding API](http://docs.blocknative.com/ethernow/batch-decoder-api): decode OP Stack Batch transactions into their human-readable JSON format.
* [Blob Archive API](https://docs.blocknative.com/blocknative-data-archive/blob-archive): take any versioned hash of an OP Stack Blob and receive the blob data (even beyond the 4096 epoch window of storage).
* [Mempool Archive](https://docs.blocknative.com/blocknative-data-archive/mempool-archive): Analyze any OP Stack transaction that was in the Ethereum mempool to see detection time, time pending, gas, etc.
* [Ethernow Explorer](http://ethernow.xyz): Visually see transactions and batches enter the mempool and get organized into blocks. Use this filter to see OP Stack Batches enter the mempool and land on-chain.

## Tenderly

[Tenderly](https://tenderly.co/?mtm_campaign=ext-docs\&mtm_kwd=optimism) provides comprehensive monitoring and security solutions for OP-powered Chains, allowing you to stay informed and respond proactively to potential issues in real time.

* Configure [Tenderly Alerts](https://docs.tenderly.co/alerts/intro-to-alerts?mtm_campaign=ext-docs\&mtm_kwd=optimism) for monitoring wallets and setting up real-time notifications on transactions and contract events. Notifications trigger external webhooks, PagerDuty, or chat apps like Telegram and Slack.
* Rely on [Developer Explorer](https://docs.tenderly.co/developer-explorer?mtm_campaign=ext-docs\&mtm_kwd=optimism) to monitor and analyze transaction execution with a high level of detail.
* Use [Web3 Actions](https://docs.tenderly.co/web3-actions/intro-to-web3-actions?mtm_campaign=ext-docs\&mtm_kwd=optimism) to automate predefined responses, improving security and user experience.
* Integrate [Simulation RPC](https://docs.tenderly.co/simulations/single-simulations#simulate-via-rpc?mtm_campaign=ext-docs\&mtm_kwd=optimism) to predict transaction outcomes such as the expected asset changes, precise gas usage, and emitted events.

## Dune Analytics

[Dune Analytics](https://dune.com) allows anyone to create dashboards that present information about OP Chains (OP Mainnet, Base, and Zora are available). See [Dune Docs](https://dune.com/docs/) for more info.
You can find a list of community created dashboards for OP Chains [here](https://dune.com/browse/dashboards?q=tags%3Aop%2Coptimism%2Csuperchain\&order=trending\&time_range=24h), or [create your own](https://docs.dune.com/#queries) dashboard.

For developers building apps on OP chains, Dune's developer platform, [Sim](https://sim.dune.com/), provides real-time onchain data access via [Sim APIs](https://docs.sim.dune.com/) and custom indexing with [Sim IDX](https://docs.sim.dune.com/idx).

Here are some of our favorite dashboards so far:

* [OP Chains / Superchain - L2 Activity, Chain Economics](https://dune.com/oplabspbc/op-stack-chains-l1-activity)
* [OP Chains / Superchain - Popular Apps & Project Usage Trends](https://dune.com/oplabspbc/superchain-op-chains-apps-and-project-usage-trends)
* [By OP Chain - L2/L1 Chain Economics](https://dune.com/oplabspbc/optimism-l2-l1-economics)
* [OP Token House Delegates](https://dune.com/optimismfnd/optimism-op-token-house)
* [Superchain NFTs](https://dune.com/oplabspbc/superchain-nfts)
