Pricing

Simple pricing that never charges you for good housekeeping.

A tier sets what the platform can do. A band sets how much capacity you commit to. Pick one of each, or start on Free and upgrade when you're ready.

AXIS 1 · TIER

What the platform will do

Chains, webhooks, Edge sessions, SSO, hardware keystores, audit retention and support.

AXIS 2 · BAND

How much capacity you commit to

Active addresses, included settled transactions, overage rate and API rate limit.

YOUR PLAN

One monthly fee, plus overage only if you use it

Overage is charged, never blocked. Only the address cap stops you, and it prompts an upgrade.

Capability tiers

Free is a real tier, not a trial: enough to build, test and run something small.

Capacity bands

Size on active addresses, not volume. If you run well over the allowance, the next band up is often cheaper than the overage, which is what the blended figure shows.

Talk to sales

Upgrades apply immediately and are prorated. Downgrades apply at the end of the period. Going over your address cap prompts an upgrade, and we never silently reprice you.

We only bill a transaction when real money settles.

A settled transaction is a confirmed deposit or withdrawal, counted once, however many confirmations or webhooks it triggers.

Why sweeps are free
Charging for them would push you to sweep less and leave funds scattered. Sweep as often as the chain fees justify.

Estimate your plan

Customers × the addresses each one needs ≈ active addresses. Ethereum, BNB Chain, Polygon, Avalanche and Base share one address.

$499 band fee · no overage
Band fee and overage only. Premium and Ultimate tier pricing is quoted separately. Chain network fees are paid from your own gas tanks.

Taking payments? Same pricing.

Payment addresses don't count against your band's address cap. Each confirmed payment counts as a settled transaction. Running a gateway for other merchants? Set your own commission per merchant, and ChainOS records it in the settlement book.
