Understanding the basic mechanics of the mempool can help you avoid many common errors. The solana-playground smart contract is designed for high security, but it requires valid parameters to execute. To handle the conflict , ensure that only one web3 extension is active. A common mistake is trying to send a new transaction while one is pending.
A mismatch in the chain ID settings will prevent solana-playground from connecting to the blockchain. Most minor glitches are resolved automatically once the global network congestion subsides. It is worth checking for any active governance proposals that change logic. Always verify that the website you are using is the official one to avoid malicious scripts.
Layer 2 network delays can sometimes lead to “ghost” transactions that appear later.
