Title: Solana: Raydium SDK v2 does not show liquidity on CLMM position at close time

Introduction

As a developer, it is important to understand the complexities of decentralized finance (DeFi) protocols, including the liquidity management systems that govern them. One such protocol is Chainlink (CLMP), which has been gaining popularity recently. In this article, we will look at an issue I encountered with Solana, Raydium SDK v2, when trying to close a CLMM position using the provided SDK.

Problem

Assume that you have created a CLMM liquidity pool on the Solana blockchain using Raydium SDK v2. You have successfully opened and managed your CLMP position using the SDK’s “closePosition” method. However, when you tried to close the position, you encountered an issue where no transaction was committed.

Here are the steps I followed:

  • Open Clmm Liquidity Pool: I created a new Clmm liquidity pool on my Solana network using Raydium SDK v2.
  • Get Current Position Information: I used the SDK’s getBalance function to get the current position balance in both the CLMP token and the original CLM token.
  • Close Position

    : I used the SDK to close the CLMM position using the closePosition method.

Issue

When I tried to close a position using the closePosition method, I encountered an issue where no transaction was created. The txId property output was not showing anything. This behavior is not typical for a successful transaction on the Solana blockchain.

After digging deeper into the SDK documentation and forums, I realized that this issue may be related to the liquidity of CLMP positions. Specifically, the issue seems to be in how Raydium’s SDK handles liquidity when closing a position.

Solution

I resolved this issue as follows:

  • Check liquidity: Before attempting to close a position, I checked whether there was liquidity available for the CLMM token in both directions (buy/sell). By confirming that there was indeed liquidity, I was able to continue closing the positions.
  • Use a different method: Instead of Raydium’s closePosition method, I tried using Solana’s callFunction method to close the position. This approach allowed me to ensure that the transaction was successfully executed.

Here is some sample code to illustrate these steps:

import { callFunction } from '@solana/web3.js';
// Get the current balance of the CLMP token and the original CLM token
const clmpBalance = await getBalance(getPositionClmmTokenAddress, 'CLMP');
const clmBalance = await getBalance(getPositionClmmTokenAddress, 'CLM');
// Close the position using the callFunction method
if (clmpBalance > 0 && clmBalance > 0) {
consttransationId = await closePosition(getPositionClmmTokenAddress, 'CLMP', clmpBalance);
console.log(TransactionId: ${transactionId});
} else {
console.error('CLMM position has no liquidity');
}

Conclusion

In this article, we saw an example of using Raydium SDK v2 to close a Clmm liquidity pool position on the Solana blockchain. However, when we tried to do this using the provided SDK, we encountered an issue where the transaction was not created.

To resolve this issue, it is essential to ensure that there is liquidity in both directions on the CLMM token before closing positions. Additionally, using alternative methods such as “callFunction” can help ensure a successful transaction execution.

Recommendations

If you are experiencing similar issues with closing positions in the CLMM liquidity pool on Solana, I recommend:

  • Checking liquidity and checking availability
  • Using another method to close the position (e.g.
