UTXO Mean Age (Days)
Definition
The simple average age in full days of all unspent transaction outputs. \
Release History
Release Version: NDP-EOD 4.8 (Nov, 2020)
Interpretation
This metric calculates the average number of days an asset (e.g, BTC) is held between transactions. Note that it may be less robust to outliers than median and could be skewed by older addresses.

UTXO Cnt
Definitions
The sum count of unspent transaction outputs that interval.
Details
Unspent Transaction Outputs (UTXOs) are cryptoasset balances that have been received by the output addresses listed in a transaction. As transactions are comprised of senders (input addresses) and receivers (output addresses), only the owner of output addresses can spend them after the transaction confirms. Said differently, UTXOs are balances received that have not yet been spent by their owners. Collectively, the UTXO set constitutes the current ownership state of a cryptonetwork. Bitcoin is the first and most predominant network that uses this structure, but there are several other UTXO-based chains.
Asset-Specific Details
For BTC and derivatives asset, it doesn’t include OP_RETURN outputs as they are provably unspendable.
Release History
Released in the 4.0 release of NDP
Interpretation
This metric gives a proxy for an asset’s ownership fragmentation. If there’s not a lot of unspent outputs, then there cannot be a lot of onchain owners. More broadly, the UTXO set count is an upper bound estimate on the number of people owning funds on-chain.
Availability for Assets
UTXO Age-Weighted Value (native units)
Definition
The sum product of age in full days and value in native units of all unspent transaction outputs.
