In a bear market, you should stay away from financial management and accumulate low-priced chips; only in a bull market should you embrace financial management.
I looked at the two transactions of the attack, the Hacker constructed several abnormal transactions that triggered risk control, and the funds were not damaged. Kudos to the security design of REE, fighting Liu Laoshi @louisliubj
If you want to transfer funds with low fees but your wallet doesn't support it, you can try OPSAT's Sparrow transfer tool. It can intelligently send available funds and also supports on-chain automatic consolidation of all UTXOs like Sparrow, making it efficient and worry-free.
Computation has never been the bottleneck; if independent verification logic changes, the foundation of blockchain ceases to exist. Shared computation is distributed cloud, not blockchain.
The part regarding transaction cancellation has been optimized again. Previously, there were cases where transactions could not be canceled when using certain normal fee mining pools like via pool. More mining pools with normal fees have been added for canceling transactions at different fee rates to increase the success rate.
Recently updated the limits for low-fee broadcasting, and the tool Sparrow now supports direct BTC transfers. Endure until spring arrives and the lights shine brightly, and good things will always happen.
