I can guide you through the process of remedying the problem to return to the universal router for Ethereum (ur) with a sales of tokens in the basic network.
Introduction
The universal router is a decentralized bridge that allows you to use external chains, such as the smart binance chain or optimism, to launch sales of tokens on the mainnet. However, this can lead to transactions if the contract on the external chain is not properly configured or if the relay chain contract has problems.
Return problem
When a token sale uses the universal router and triggers a withdrawal from the base network in the target chain, it can cause a return error. This happens because:
- The withdrawal function in the basic network contract is expected at a specific signature, but the external chain chain contract offers a different signature.
- The relay chain contract has a problem that prevents confirmation of the transaction.
Solving the Return problem
To solve this problem, you will need to change the Ethereum -based 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 “withdrawal” function that accepts a specific signature:
`Javascript
Withdrawal function (sum) {
// …
Return {Date: ‘0x …’}; // replace with real signature
}
`
Then update the code to call this feature and manage any errors:
Javascript
const {bignum} = requires (‘bignumber.js’);
Const Routerabi = …;
Const BasenetWorkContract = new contract (BasenetWorkaddress, Routerabi, ‘BasenetWorkContract’);
Async Function Retracts () {
Try {
Constant the sum = waiting for BasenetWorkContract.withDraw (sum);
// …
} Catch (error) {
console.error (error);
// manage the error and try again
}
}
`
2. Update the universal router configuration
In the universal router configuration, update therelatedchain ‘settings to indicate the correct contract on the target chain:
`Javascript
const universalrouuter = new universalrouter ({
BasenetWorkaddress: ‘0x …’, // basic network address
Velychainadress: ‘0x …’, // address of the target chain
VelychainContract: “VelychainContract”, // relay chain contract abi
});
`
Make sure you replace addresses and contracts with your real values.
3. Update the token sale contract
In the contract of sales with tokens, update thewithdrawal function to use the correct signature:
`Javascript
Async Function Retracts () {
Try {
Constant the sum = waiting for BasenetWorkContract.withDraw (sum);
// …
} Catch (error) {
console.error (error);
// manage the error and try again
}
}
`
Update the relay chain contract
If you use a relay chain contract, update the "Withdrawal" function to use the correct signature:
Javascript
Async Function Retracts () {
Try {
Constant the sum = waiting for BasenetWorkContract.withDraw (sum);
// …
} Catch (error) {
console.error (error);
// manage the error and try again
}
}
“
5. Test your code
Once you have done these updates, test the code in detail to make sure the problem is solved.
Conclusion
Fixing the return problem in the universal router for Ethereum can be difficult, but by updating your contracts and configuration. Remember to test your code in detail after doing these updates to make sure everything works as expected.
