Bitcoin Ethereum Transaction Error: Minimum Mempool Fee Not Reached
As a frequent user of the Ethereum blockchain, it is frustrating to encounter errors that prevent you from sending Bitcoin (BTC) and other cryptocurrencies. In this article, we will dig deeper into the problem and provide solutions to help you fix the “Minimum Mempool Fee Not Reached” error on your Bitcoind client.
What is Mempool?
In the Ethereum blockchain, a mempool is a queue of transactions waiting to be executed by the network. If a transaction has enough space available in the mempool and it meets certain conditions (such as sufficient funds and enough time since the last update), it can be executed, resulting in an “out of mempool” error.
Error #26: Minimum mempool fee not reached
If you see the following message:
BitcoindException(super=com.neemre.btcdcli4j.core.BitcoindException:
Error #-26:66: Minimum mempool fee not reached, code=-26)
indicates that the bitcoind client encountered an error while attempting to execute a transaction because there was not enough space in the mempool. This error can be caused by several reasons, including:
- Not enough memory available in the mempool
- Excessive network congestion
- High demand for Bitcoin transactions
Solutions to fix “Mempool minimum provision not reached” error
To fix this problem, follow these steps:
- Increase mempool size: You can increase the size of the mempool by adding a “–max-memory” or “–mempool-size” parameter when running bitcoind. For example:
- Using “bitcoind -m 10000” will increase the maximum memory available in the mempool to 10,000 bytes.
- Adjust network congestion: If the problem is caused by high network congestion, try reducing the number of connections or increasing the network connection timeout. You can do this by adding a
--network
parameter, such as:
- “bitcoind –network=eth1” to use the Ethereum network instead of the default testnet.
- Increase mempool size in large-scale scenarios
: If you are working in a large-scale environment with many transactions, increasing the mempool size can help alleviate congestion issues.
- Try using a different Bitcoin client: Some Bitcoind clients may have bugs that affect mempool behavior. You can try switching to a different client, such as “bitcoind-cmd” or “bitcoin-cli”.
- Increase Bitcoin transaction processing time: If you have high transaction demand, increasing the transaction processing time (TPT) on your mining rig can help alleviate congestion issues.
- Check for updates and bug fixes: Make sure Bitcoind is updated to the latest version, as newer versions often fix performance and security issues.
Other tips
- Clear the mempool regularly by running “bitcoind –clear-mempool” or “bitcoin-cli clearmem”.
- Use a reliable and fast network connection when sending transactions.
- Consider using more powerful mining equipment or upgrading your hardware if you are facing high transaction volumes.
By following these steps and changing your Bitcoind settings, you should be able to resolve the “minimum fee for mempool not reached” error and continue to successfully send Bitcoin transactions over the Ethereum blockchain.
