Ethereum: Understanding and Resolving MetaMask RPC Errors
As a beginner to building Ethereum-based projects, it’s not uncommon to encounter errors when interacting with your Ethereum blockchain. A common error that can occur is “RPC Error: Method eth_maxPriorityFeePerGas does not exist/is not available” from the MetaMask browser extension.
In this article, we’ll break down what each part of the error message means and provide guidance on how to resolve it using Hardhat, a popular tool for building Ethereum-based smart contracts.
What is MetaMask?
MetaMask is a browser extension that allows users to interact with the Ethereum blockchain without having to install a full node or copy your private key. It provides a simple way to manage Ether and other assets, as well as access various tools and services related to your Ethereum wallet.
“RPC Error”
RPC stands for Remote Procedure Call, which is a protocol used to execute functions remotely in a distributed system. In this case, MetaMask’s RPC endpoint is the Ethereum Virtual Machine (EVM), which allows developers to interact with the blockchain programmatically.
When you use MetaMask in a headset or other application that interacts with the EVM, it typically sends and receives transactions using RPC calls. However, if an error occurs while making these RPC calls, such as the message “RPC Error: The method eth_maxPriorityFeePerGas does not exist/ is not available,” MetaMask will display this error.
Understanding the eth_maxPriorityFeePerGas Method
The eth_maxPriorityFeePerGas method is used to adjust the priority of a transaction in terms of gas cost. By default, Ethereum transactions have a fixed gas price that determines their priority; higher gas prices result in lower priority.
When you want to optimize smart contract execution time or reduce gas costs, you may need to modify this method to suit your needs. However, if the eth_maxPriorityFeePerGas method is not available, it means that Ethereum has changed its behavior and no longer supports this specific RPC call.
Resolving the error
To resolve the message «RPC Error: Method eth_maxPriorityFeePerGas does not exist / is not available» from MetaMask in Hardhat, follow these steps:
Check Hardhat configuration: Make sure that the Hardhat configuration file (e.g. hardhat.config.js) is configured correctly to use the MetaMask RPC endpoint.
Check MetaMask version: Make sure that you are using a compatible version of MetaMask for your blockchain. Ethereum (e.g. Web3.js v1.x).
Update Hardhat or MetaMask: If you are using an outdated version of Hardhat, update to the latest version and make sure it supports the Ethereum blockchain.
Check for conflicts with other RPC endpoints: Make sure you are not accidentally switching to another RPC endpoint (e.g. eth_sendTransaction) with the eth_maxPriorityFeePerGas method.
If none of these steps resolve the issue, try updating MetaMask to the latest version or try using a different RPC provider, such as Truffle’s built-in RPC endpoint.
Conclusion
In this article, we explored what the «RPC Error: The method eth_maxPriorityFeePerGas does not exist/ is not available» message from MetaMask in Hardhat means and how to resolve it. By understanding the basic issues and following these steps, you should be able to resolve this error and continue building your Ethereum-based smart contracts using MetaMask with Hardhat.
