Odaily News On November 28, Bitcoin ecosystem service provider UniSat announced the official launch of the "less than 1 sat/vB" fee rate model in its UTXO management tool. This feature allows users to set a custom fee rate of less than 1 sat/vB (0.1-0.9 sat/vB) when network conditions are suitable, recycling idle UTXOs into usable Bitcoin, thereby dropping the cost of capital recovery. The tool can automatically categorize scattered UTXOs generated from brc-20 minting and transfer operations and provides a one-click merge and recycle function. For example, using a Native SegWit Address containing 500 UTXOs (each 546 sats), a fee rate of 0.1 sat/vB can achieve a 98.7% capital recovery rate, which is about 11.7 percentage points higher than the standard fee rate of 1 sat/vB. In addition to the asset recovery feature, the UTXO management tool's bulk sending, splitting, unlocking, locking, and merging standardized operations also now support low fee rate models. The platform also reminds users that low fee transactions may experience extended confirmation times or may not be confirmed at all during periods of network congestion, and it is recommended that users flexibly adjust their fee rate strategies based on real-time network conditions.
