Recommended actions

  1. 1Monitor the fee-fragile UTXOs and compare consolidation costs during lower mempool demand.
  2. 2Preserve privacy boundaries: consolidation can reveal that separate payments belong to the same wallet owner.
  3. 3Compare the result with the UTXO Consolidation Calculator before creating a transaction.
  4. 4Let your wallet calculate and display the final transaction before approving anything on a signing device.

Methodology, data and limits
  • Values stay in this page and are not associated with addresses, labels or wallet ownership.
  • Economic exposure means an estimated input cost approaches the UTXO value; it is not the same as a transaction-output dust policy threshold.
  • Combining UTXOs may save fees but can reveal common ownership and damage privacy.
