Missing swap agreement from Solana transaction: Troubleshooting guide
As a Solana developer, you have probably encountered issues where a transaction was sent using the Solana protocol but did not work as expected. One common error is that it does not switch between two accounts.
In this article, we will take a closer look at these events and provide step-by-step instructions on how to troubleshoot and resolve issues.
Issue: Missing swap
When a transaction is sent via Solana using a transfer or swap function, there must be an associated swap function. The swap function is used to exchange tokens between accounts. However, if the swap operation does not go through, the transaction will not succeed as expected.
The bid response and swap response are two essential elements of a successful transaction in Solana:
- Quote: Represents the current price of the asset at a given timestamp.
- Swap: Used to replace one character with another. The « swap » statement requires the amount and recipient accounts.
Missing Swap Example
Let’s say you send a transfer transaction with a response in the form of a quote containing the price of a specific cryptocurrency:
json
{
« method »: « transfer »,
« from »: « account1 »,
« to »: « account2 »,
« sum »: « 10.0 »,
« quote »: {
« assetId »: « eth1 »,
« timestamp »: 1643723400,
« price »: 100.00
}
}
« `
If the swap function is missing, you might see an error message saying that the transaction did not exist in Solana Explorer.
How to check if your exchange is missing
To check if your switch operation was successful, do the following:
- Use Solana Explorer
: Open Solana Explorer in your browser and navigate to the address of the account you are transferring.
- Check Event History: Check the Event History section in Explorer. Look for events related to “transfer.”
- Check Exchange Instruction: If there is an exchange instruction, make sure it contains all the required fields.
Troubleshooting Steps
If you have checked and confirmed that your exchange operation has been completed, here are some steps:
- Check Transaction ID: Double check that the txid field of the transaction matches the field provided in the offer response.
- Check for Errors: Check the Event Log section of Solana Explorer for any error messages indicating missing exchange operations or other issues.
- Recreate the event: If necessary, recreate the event using the same “txid” and required fields.
Conclusion
A lack of swap is a common issue with transactions sent via Solana. By following these steps, you should be able to identify and resolve issues related to missing exchange features. Make sure you have checked all required fields in your transaction, including transaction data and exchange instructions. If you are still having trouble, consider reaching out to the Solana community or seek help from a qualified developer.
