Build on Tuven

Understand sponsored gas

How configured gas plans can change the asset used to pay for a transaction.

Tuven’s sponsorship registry can assign eligible accounts to a gas plan. A configured plan specifies a payment token, a flat fee per transaction, and a beneficiary. This is an alternative gas policy, not a blanket promise of free transactions.

Normal and sponsored accounts

An account without a plan pays normal network gas in USDX. An account on a supported plan pays its configured flat fee in the plan’s token, while the USDX gas charge is waived. The account must hold enough of the fee token.

Read the active policy

Integrations can inspect SponsorRegistry.userPlan(address), plans(planId), and resolveGas(address). Plan assignments can be managed by authorized sources such as the network’s soulbound-token system. Always read current policy rather than inferring eligibility from a token name.

Handle unavailable plans

If the configured payment token is missing or the account lacks the required fee-token balance, the transaction can be rejected at admission. Use the intended sender for gas estimation, surface the node’s error, and offer a clear explanation of the missing balance or unsupported plan.
