Understanding of the Solana curve calculator: DestinationMountswpped zero '
The notorious "DestinationMountswApped" error! This is a general question if you work with the Solana Curve calculator and troubleshooting can be frustrating. In this article, we dive into what this error means, how to identify it, and most importantly, how to fix it.
What is "DestinationMountswPped"?
The "DestinationMountswPPED" error occurs when it contains the target amount of a replacement request (ie the amount sent to the reserve is now being received). This can happen in several scenarios:
- Incorrect quotation reserve
: If the input amount quote is set to 0 and tries to send it to another reserve, Solana will replace it with its original destination.
2.
Example of the question
Let's look at an example with Raydium V2 SDK:
Javascript
Const Swapresult = Curvecalculator.Swap (
Inputamount,
Basein? Basereserveve: Quotererve,
// some additional parameters ...
);
Assuming that the “Basereserve” and “Quotererve” are not set to zero values, the error occurs because the “DestinationMountswPed” is set to 0:
`Javascript
{{
"Status": {
"Error": [
{{
"Code": 1,
"OK": "DestinationMountswApped"
}
]
},
"Data": {}
}
Troubleshooting steps
To solve the problem, you can try the following:
- Check quotation reserve
: Make sure
Quotereserve 'is not set to 0.
- ** Check the replacement failure logs.
- Check the inputs and outputs : Check that "inputamount" is used correctly and that the replacement parameters are properly set.
Example Solution
To solve this problem, you can add a simple verification before replacing the replacement:
Javascript
constinamount = curvecalculator.getbalance ("input", "from");
if (inputamount === 0) {
throw a new error ("The quote reserve is not zero.");
}
const basein = basereserve;
Const quotereserve = quotereserve;
Curvecalculator.Swap (
Inputamount,
Basein? Basereserveve: Quotererve,
// some additional parameters ...
);
By adding the check, it ensures that the “DestinationMountswPed” is not set to zero before attempting to replace.
I hope this explanation and example will help you solve the “Error: DestinationMountswPed a zero” problem when using Raydium V2 SDK with the Solana Curve calculator!
