UTXO value band check. SATISFIED if the input amount falls within a configurable [low_sats, high_sats] range. Enables value-gated spending paths and tiered authorization policies.

Description
high_sats
NUMERIC
1-4 B
Conditions
Upper bound of the value band (satoshis)
low_sats
NUMERIC
1-4 B
Conditions
Lower bound of the value band (satoshis)
No witness fields required. Evaluation uses the input amount from the UTXO being spent.
This allows spending only if the UTXO value is between 0.001 BTC and 0.1 BTC. UTXOs outside this range require a different spending path.
Use Cases
Value-Gated Spending Paths
Different authorization policies for different UTXO sizes. Small amounts use a single signature, while larger amounts require multisig or time-delays, all enforced at the covenant level.
Tiered Authorization
Organizational spending tiers where petty cash (under threshold) flows freely, mid-range requires manager approval, and large amounts need board authorization — each tier a separate ladder rung gated by HYSTERESIS_VALUE.
