Sponsorship

Some collections sponsor the bridge infrastructure fee of their users.

Sponsoring collections load a feeManager contract which manages the funds.

The FeeManager smart contract sponsors the user's NFT transfer by sending funds to the bridge on behalf of the user provided the necessary funds have been topped up by the collection.

In this case, the user has to pay the remaining fee after negating the collection fund balance and the CCIP Network fee and the transaction's gas fees.

The exact amount of funds sponsored for your transaction is seen while bridging as shown below after the bridge fee is estimated.

In case the FeeManager runs out of funds for the collection, the user has to pay for the transaction and will be refunded by the collection after a while through NFT Bridges on the Bridge Rewards page.

If you are a collection owner and you want to sponsor your users to bridge, your address needs to be added to our whitelist to topup funds for your collection. After your address is added to the whitelist, you can topup your collection here. To add your address to our whitelist or for any other queries, please contact us here.
