Ethereum: How to fix revert problem in universal router?
I can help you repeat the problem of preventing the Universal router in Ethereum (UR) with a marker on the base network.
Introduction
The universal router is a decentralized bridge that allows the use of external circuits such as binance smart chain or optimism to start selling markers in Mainnet. However, this may lead to the return of transactions if the external chain agreement is not properly configured or if the relay chain agreement has problems.
Restoration problem
When the marker sale uses a universal router and causes removal from the base network to the target chain, it can cause a reversible error. This is because:
- The deprivation function of the base network awaits a special signature, while the external circuit relay circuit contract provides a different signature.
- The relay chain agreement has a problem that prevents the transaction from confirming.
Restoring problem
To prevent this problem, you will need to change contracts based on Ethereum and update the universal router configuration. Here are some steps to take:
1. Update the Base Network Agreement
Add a “Undo” feature in the basic network agreement that accepts a specific signature:
`JavaScript
Function Remove (amount) {
// …
Return {data: ‘0x …’}; // Replace with the actual signature
}
`
Then update the code to call this feature and process any errors:
`JavaScript
Const {bignumber} = ask (‘bignumber.js’);
Const Routerabi = …;
Const BasenetworkContract = New Agreement (Basenetworkaddress, Routerabi, ‘BasenetworkContract’);
ASYNC Function Removal () {
Try {
Const sum = wait for basenetworkcontract.withdraw (amount);
// …
} Catch (error) {
Console.Error (error);
// Action with an error and try to repeat
}
}
`
2. Update the universal router configuration
Update the “Relaychain” settings in the universal router configuration to indicate the correct target chain contract:
`JavaScript
Const UniversalRouter = New UniversalRouter ({
Basenetworkaddress: ‘0x …’, // Base Network Address
Relaychainaddress: ‘0x …’, // Target Chain Address
RelaychainContract: ‘RelaychainContract’, // Relay Chain Agreement Both
});
`
Make sure the addresses and contracts have replaced their actual values.
3. Update the marker sales contract
Token in the Sales Agreement Update the “Recall” feature to use the correct signature:
`JavaScript
ASYNC Function Removal () {
Try {
Const sum = wait for basenetworkcontract.withdraw (amount);
// …
} Catch (error) {
Console.Error (error);
// Action with an error and try to repeat
}
}
`
4. Update the relay chain contract
If you are using a relay chain contract, update its function Remove 'to use the right signature:
JavaScript
ASYNC Function Removal () {
Try {
Const sum = wait for basenetworkcontract.withdraw (amount);
// …
} Catch (error) {
Console.Error (error);
// Action with an error and try to repeat
}
}
`
5. Check your code
Once you have made these updates, carefully check the code to make sure the restoration problem is resolved.
Conclusion
Prevention of restoration problem in the Ethereum universal router can be challenging, but by updating the contracts and configuring accordingly, you should be able to solve the problem and successfully launch the marker on the base network. Remember to carefully check the code after these updates are made to ensure that everything works as expected.
