Ethereum: How to fix revert problem in universal router?
I can lead you through the process of solving the problem of return at the Universal Router for Ethereum (UR) with the sale of a token in the base network.
Introduction
A universal router is a decentralized bridge with which you can use external chains, such as the intelligent Binance chain or optimism to start tokens sales on the main network. However, this can be attributed to the transaction if the contract for the external chain is not properly configured or if the contract has problems.
Return problem
If the token sales are used by the Universal Router and starts payment from the basic network to the destination chain, this may lead to a return error. It happens because::
- The function of the deduction in the basic network contract expects a certain signature, but the contract for the relay of the external chain offers a different signature.
- The relay contract has a problem that prevents the transaction from confirming.
Release the problem with return
To solve this problem, you must change your ETHEREUM contracts and update the Universal Router configuration accordingly. Here are a few steps to follow:
1. Update the basic network contract
In the basic network contract, add a “selection” feature that accepts a certain signature:
`Javascript
Pull out the function (amount) {
// …
Return {data: ‘0x …’}; // replace the actual signature
}
`
Then update your code to call this feature and treat all the mistakes:
`Javascript
Const {Binnumber} = Requirements (‘Bignumber.js’);
Const routerabs = …;
Const BasetworkContract = new contract (Setworka, routerabi, ‘Basic SetworkContract’);
ASYNC FUNCTION FULLING () {) {
attempt {
Const Seng = waiting base setworkcontract.withdraw (amount);
// …
} Catch (Error) {
Console.error (Error);
// bypassing and repeating errors
}
}
`
2. Update the Universal Router configuration
Update the “Relaychain” settings in the Universal Router configuration to indicate the correct contract in the destination chain:
`Javascript
Const Universal Router = New Universal Router ({{{
BASETWORKADDRESS: ‘0x …’, // basic network address
Relaychainaddress: ‘0x …’, // target chain address
Relatechain contract
});
`
Be sure to replace addresses and contracts for your actual values.
3. Update the tokens’ sale contract
Update the “Lift” feature in the tokens sale contract so you can use the correct signature:
`Javascript
ASYNC FUNCTION FULLING () {) {
attempt {
Const Sum = waiting base setworkcontract.withdraw (SUM);
// …
} Catch (Error) {
Console.error (Error);
// bypassing and repeating errors
}
}
`
4. Update the relay contract contract
If you are using a relay chain contract, update the “Departure” feature and use the correct signature:
`Javascript
ASYNC FUNCTION FULLING () {) {
attempt {
Const Seng = waiting base setworkcontract.withdraw (amount);
// …
} Catch (Error) {
Console.error (Error);
// bypassing and repeating errors
}
}
`
5. Test your code
Once you have done these updates, thoroughly test your code to make sure the return on the return on the return was resolved.

Solving the problem of returning in the universal router for Ethereum may be a challenge. By updating your contracts and configurations, you should be able to solve this problem and successfully start selling tokens on the base network. After submitting these updates, be sure to test your code thoroughly to make sure everything works as expected.
