🔴 Ecosystem Project Idea: Transaction Replay Tool

[smartcontracts]

What is an Ecosystem Project Idea?

An Ecosystem Project Idea is an idea for a project that someone could build within the Optimism ecosystem. As opposed to an Ecosystem Concept or an Ecosystem Idea, an Ecosystem Project is generally more fleshed out and corresponds to a relatively clear product to be built.

Summary

As it currently stands, users need to utilize the SDK or other low-level mechanisms to replay L1 => L2 or L2 => L1 transactions that ran out of gas. This can be complex for average users. A good tool would provide an interactive user interface for replaying transactions. This tool aims to simplify this process and make it more accessible.

Potential Features

• Query and Display Failed Transactions: The tool would provide functionality to query both L1 and L2 chains using a user's public address to find transactions that have failed due to running out of gas. Should also be able to support searching by a specific transaction hash.
• Customize Gas Limit: The user interface would allow users to specify a higher gas limit for replaying the failed transaction.
• Safe Replaying: Before replaying, the tool should provide a cost estimation for the transaction and ask for user confirmation, this makes sure that the custom gas limit is going to be high enough.
• Tutorial and Help: The tool would include a brief tutorial or walkthrough on how to use it, along with tooltips or help text to guide users.
• Real-time Updates: The tool would offer real-time updates on the status of the transaction once replayed.
• Transaction History: It should have the functionality to keep a history of all replayed transactions for a given address.

Impact

• Increased Usability: This tool will drastically improve the experience for users who face gas issues during transactions between L1 and L2.
• Accessibility: It will make L2 interactions more accessible for non-technical users by removing the need to use the SDK for these transactions.
• Reduced Transaction Failures: The tool will help to reduce the number of failed transactions on the network, leading to improved overall network health.
• Better User Experience: By giving users control over their gas limits, it provides a more personalized and user-friendly interaction with L2.
• Educational: This tool can serve as an educational resource for users to better understand gas costs and transaction dynamics in L2.

I created an Optimism transaction replay tool UI that lets users input an account address to see recent cross-chain messages for the account and replay transactions the are either unrelayed or a failed relay. It lets the user specify a custom gas limit and shows the estimated gas cost in ETH.

The rest of the suggested features coming soon.

Hi @buildooor are you still busy with this?
