Free Operations

Free Operations

Tip

This is handled automatically by Varity. No developer configuration needed. When you deploy with varitykit app deploy, your app automatically gets free operations for all users.

• 10% goes to Varity (platform fee)

This is enforced automatically by the platform. No invoices, no payment processing — it happens automatically.

Billing for Developers

• Beta: Free — all operational costs are covered using shared development credentials
• Production: Usage-based billing through your Varity account

How Gas Sponsorship Works Under the Hood

Varity uses ERC-4337 account abstraction to sponsor gas fees:

1. User initiates action — clicks a button in your app
2. Smart account encodes the operation — a UserOperation is created
3. Bundler submission — the operation is sent to the bundler network (Conduit)
4. Paymaster approval — Varity’s paymaster agrees to cover the gas cost
5. Execution — the operation executes on Varity infrastructure
6. Confirmation — user sees success

All of this happens in seconds, completely invisible to users. The smart wallet infrastructure (ZeroDev Kernel smart accounts, authentication, Conduit for bundler and paymaster) is managed by Varity. Developers do not need to configure any of these components.
