Pricing Model

Addressing Variable Market Conditions

The future market landscape is unpredictable, and ArNS is designed to adapt without relying on a centralized pricing oracle. Instead of fixing name prices to an external currency, the protocol adjusts pricing based on network activity and registration demand.

This keeps ArNS self-contained while still allowing name prices to respond to changing market conditions over time.

ArNS pricing is built from a few core ideas:

  1. Name length: Shorter, more memorable names generally cost more.
  2. Registration type: Names can be leased for a defined period or purchased permanently.
  3. Demand Factor: A protocol multiplier adjusts prices based on recent ArNS activity.
  4. Returned Name Premium (RNP): Recently expired or returned names re-enter the market through a descending premium window.

This approach lets ArNS remain predictable enough for users while still adapting to namespace demand.

You can view current live pricing at arns.ar.io to see these formulas in action.

Key Definitions

  • Demand Factor: A protocol multiplier that adjusts prices based on recent registration activity.
  • Base Fee: The starting price for a name before dynamic adjustments.
  • Lease: A time-limited registration.
  • Permabuy: A permanent registration.
  • Undername: A subdomain-style record written with an underscore (_) instead of a dot (.).
  • Protocol Revenue: ARIO collected from ArNS actions, such as name registrations, lease extensions, and undername purchases.

Dynamic Pricing Model

ArNS uses an adaptive model to balance name availability, demand, and long-term sustainability. Prices are influenced by name length, whether the name is leased or bought permanently, undername capacity, and the current Demand Factor.

The Demand Factor changes over time based on protocol activity. When demand is high, it can increase prices; when demand is low, it can decrease prices. If demand remains low for long enough, the protocol can step base fees downward so names stay accessible.

For exact costs, users should rely on the live ArNS app or SDK cost simulation rather than copying formulas into their own applications.

Returned Name Premiums (RNP)

ArNS applies a Returned Name Premium (RNP) to names that re-enter the market after expiration or permanent return. The premium starts high and decreases over a return window until the name reaches standard pricing again.

Returned name purchases split proceeds between the protocol balance and the previous owner. This discourages instant name sniping after expiry and gives owners a reason to release names they no longer need.

Gateway Operator ArNS Discount

Gateway operators who demonstrate consistent, healthy participation in the network may be eligible for discounted ArNS interactions. This creates another incentive for gateways to provide reliable service while supporting ArNS usage.

Discount eligibility requires a Gateway Performance Ratio Weight (GPRW) of 0.9 and a Tenure Weight (TW) of 1.0. Eligible operators receive a 20% discount on new ArNS name registrations, lease extensions, lease upgrades, and undername purchases.
