Sponsored gas: who pays, and what happens if they stop

Every on-chain action costs a network fee, and someone has to pay it. Normally that is the person taking the action, which means holding a second asset purely to enable transactions in the first one — a small requirement that turns out to be a large amount of the friction in on-chain products.

Sponsorship moves that cost to the operator. The user acts; someone else pays the fee. It is genuinely useful and it is also a dependency, and the second half is discussed far less than the first.

We sponsor gas on Tradevo's free tier, so read accordingly. This page is about what that arrangement actually commits us to.

What sponsorship is, mechanically

A sponsored transaction is one where the fee is paid by an account other than the one taking the action. On networks supporting account abstraction this is a first-class mechanism — a paymaster contract agrees to cover fees for transactions meeting conditions it defines. Elsewhere it is done by the operator submitting and paying for the transaction on the user's behalf under an authorisation.

Either way the shape is the same: the user never needs the network's native token, and the operator carries a running cost proportional to activity.

That last part is the whole story. Sponsorship is not a feature that is built once; it is an ongoing expense that scales with how much people use the product.

The question to ask any sponsored product

What happens if sponsorship stops?

There are three broadly different answers and they are not equally good:

The user can still act, and pays the fee themselves. The best answer. Sponsorship was a convenience layered on top of something that works without it, and withdrawing it degrades the experience rather than breaking it. It requires the user to actually hold the native token, or be able to acquire it.

The user is stuck until the operator resumes. Sponsorship was load-bearing. If the operator runs out of funds, changes policy, or disappears, the user cannot transact — including, in the worst arrangements, cannot exit. This is the answer worth finding out about in advance.

The user's assets were never really theirs to move. Not a sponsorship question at all, but worth separating: if the user cannot act without the operator regardless of fees, the product is custodial in substance whatever it is called.

Tradevo's answer is the first. The wallet is a wallet — keys held by the user, exportable at any time. Sponsorship removes the need to hold the network's native token during normal use; it is not what makes the wallet usable. If we stopped sponsoring, the assets would still be there and still movable by the person holding the keys.

We would rather state that plainly than let sponsorship read as a benevolence that could be withdrawn with your funds behind it.

Why anyone sponsors at all

Not generosity. Requiring a user to acquire a second asset before doing anything is the single largest drop-off point in on-chain consumer products, and it is a completely artificial one — it has nothing to do with what the person came to do. Sponsorship removes a step that only exists because of how the underlying system bills for itself.

The cost is real and it constrains the product. It is one reason our free tier does not include unlimited activity, and being straightforward about that is better than implying fees vanished.

When paying your own fees is the better choice

You want zero dependency on an operator's economics. If nobody sponsors anything, nothing can be withdrawn. Holding the native token is a small price for a system with one fewer party in it.

You already hold the native token and transact often. The friction sponsorship removes is not friction you have.

You are building rather than using. Anyone writing their own transactions wants to control fee strategy directly — priority, retries, replacement — and sponsorship layers a policy in between.

When sponsorship is worth accepting

You do not want to think about a second asset. For someone whose interest is the strategy and not the network mechanics, this removes a step that teaches nothing.

The product works without it. If sponsorship is a convenience over a wallet you control, accepting it costs you very little, because withdrawing it does not trap anything.

You can verify the claim. Export the wallet, or check that the assets are at an address whose key you hold. A sponsorship arrangement is only safe to accept if the answer to "can I act without you" is demonstrable rather than promised.
