One proposed solution is to never lock UTXOs used in the transactions, but this falls short when using 0-conf. Another proposal is to lock UTXOs after tx_complete exchange if the channel has only one contributor and to differentiate 0-conf channels prior to UTXO selection to avoid reusing soft-locked UTXOs. However, this may not work for splicing. 📅 Messages Date Range: 2023-05-05 to 2023-05-10 ✉️ Message Count: 5 📚 Total Characters in Messages: 26852
