Sponsoring transactions

If you want to sponsor the transactions made by your Cometh Connect users, you will need to add the following contracts as sponsored addresses:

• The 0x proxy contract of your network, which is used in all order transactions

• Your ERC721 collection contract to sponsor allowance transactions

• The ERC20 contract used in your orders which is either:

  • If your marketplace is placed on the native token, the wrapped native token. It is used for purchase offers that require allowances. You can find the corresponding address in our networks configs file.

  • If you use a specific ERC20 token for the orders, this specific ERC20 contract.

Transactions will only be sponsored for users connected with a Cometh Connect wallet. It is not possible to sponsor transactions when using a classic wallet such as Metamask.
