The MetaMask browser extension is a wallet for accessing Ethereum-enabled applications and managing user identities. It can be used to connect to Ethermint through the official testnet or via a locally-running Ethermint node.
If you are planning on developing on Ethermint locally and you haven’t already set up your own local node, refer to [the quickstart tutorial](../../quickstart/run_node/), or follow the instructions in the [GitHub repository](https://github.com/tharsis/ethermint/).

To see your Metamask logs, click the top right circle and go to `Settings` > `Advanced` > `Download State Logs`. If you search through the JSON file for the account address you'll find the transaction history.
