Sponsored gas: subscription and top-up

What you buy. 5 USDC become one balance of your UP, valid on every available network (list below). Each operation paid by the site takes the price of the network where it runs, only when it is executed.

To top up your balance, use this same page: each 5 USDC payment is added to the balance you already have.

How to check your balance: enter your UP on this page: it shows right under the address, no MetaMask needed, or see it in the "Pay the gas with the site relayer" option of the Send and UP Wallet pages, before each operation. We also e-mail you when it goes down to 2.5, 1 and 0.5 USDC.

Before paying, on the chosen network:

1. your UP must exist on that network (if you created it on LUKSO, replicate it with the Deploy page);
2. the UP must have the 4337 setup. It is needed for the activation request (the site pays the gas of this payment) and for every later use of the sponsored gas. It is a one-time transaction per network, paid by your controller (a few cents);
3. the UP must hold at least 5 Circle-native USDC on that network (you can send them from an exchange to your UP's address).

After the payment we verify the transaction and activate the balance: you get a confirmation e-mail when it is available.

The network is only for this payment. The balance then works on every available network, whichever you choose here. Choose the network where your UP holds the USDC and has the 4337 setup.

The same address as your UP on LUKSO. The payment comes from the UP: this is how the service knows which UP to activate.

Read-only: nothing is signed. If something is missing, the button below takes you to the right page.

Privacy notice. The e-mail is used only to tell you about the activation and for communications about this service. It is kept on the service's server, linked to your UP; it is not published or given to third parties. Controller: Bertrand Juglas. To have it deleted, write to support (Telegram, bottom of the page).
