[Rumixyz]

Severity: High Description: A flaky test was skipped to avoid causing issues in the CI/CD pipeline. This needs to be re-enabled once the underlying issue is identified and fixed. Reproduce Bugs: Run the test suite. Observe that the TestSolanaChain_MultiNode_Txm test is skipped. Steps to Fix: Investigate the root cause of the flakiness in the TestSolanaChain_MultiNode_Txm test. Fix the identified issue. Re-enable the test by removing the t.Skip() line.
