# Polkadot Mempool Explorer
Mempool Explorer allow users to monitor pending transactions on [Polkadot](https://polkadot.network/).
## Environment setup
- Install [Node.js](https://nodejs.org/)
- Recommended method is by using [NVM](https://github.com/creationix/nvm)
- Recommended Node.js version is v12
- Install [Docker](https://docs.docker.com/get-docker/)
## Demo
[mempool.dot.protofire.io](https://mempool.dot.protofire.io)
## Custom Polkadot Node
In order to track extrinsics lifecycle. We added a new RPC method ([author_trackExtrinsic](https://github.com/protofire/polkadot-mempool-explorer/blob/main/api/services/polkadot/custom-rpc-methods.js)) on [Substrate core](https://github.com/jarcodallo/substrate/blob/master/client/rpc-api/src/author/mod.rs).
This basically allows someone to subscribe and track status changes in the extrinsics lifecycle, for example movements getting in or out of queues, and everything that matters for us before including those extrinsics in blocks.

- Polkadot dependencies update: [github.com/paritytech/polkadot](https://github.com/jarcodallo/polkadot/commits/master)
- Docker image of the polkadot binary: [hub.docker.com/polkadot](https://hub.docker.com/repository/docker/jarcodallo/polkadot)
