The blog discusses some reasons for transaction confirmation delays in EVM-based networks. The scripts use Python and the `web3.py` library to:\n\n* Conduct gas fee estimation\n* Send transaction\n* \"Cancel\" or \"Speed Up\" a transaction\n* handle nonce gap\n\n## Quick start\n\nBefore running the code, it is highly recommended that you go through the blog as it describes the whole logic of the code.\n\nClone this repository.\n\nInstall the Python dependencies:\n\n```sh\ncd web3.py\n```\n\nThen\n\n```sh\npip install -r requirements.txt\n```\n\nSet up your credentials in each `.py` file:\n\n```py\n# Setting node endpoint value\nCHAINSTACK_NODE_ENDPOINT = '\u003cNODE_ENDPOINT\u003e'\n\n# Setting account addressess\n# you can copy the account addresses from metamask]\n\nFROM_ACCOUNT = \"\u003cFROM_ACCOUNT_ADDRESS\u003e\"\nTO_ACCOUNT = \"\u003cTO_ACCOUNT_ADDRESS\u003e\"\n\n# Setting the user private key\nSENDER_PRIVATEKEY = \"\u003cSENDER_PRIVATE_KEY\u003e\"\n```\n\nRun the file that you want to use:\n\n```sh\npython gas_estimate.py\n```\n\n## Prerequisites\n\n* Python ^3.6\n* A node RPC endpoint.\n\nDeploy a node with Chainstack:\n\n1. [Sign up with Chainstack](https://console.chainstack.com/user/account/create).  \n1. [Deploy a node](https://docs.chainstack.com/platform/join-a-public-network).  \n1. [View node access and credentials](https://docs.chainstack.com/platform/view-node-access-and-credentials). \n\n## Dependencies\n\n* web3.py ^5.29.2\n\n## Install\n\nInstall Python on your system:\n\n* [Install Python](https://realpython.com/installing-python/)\n\nClone this repository.\n\nInstall the Python dependencies:\n  \n```sh\npip install -r requirements.txt\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fchainstacklabs%2Fevm-mempool-utilities-python","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fchainstacklabs%2Fevm-mempool-utilities-python","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fchainstacklabs%2Fevm-mempool-utilities-python/lists"}
