Use the ConfluxScan Read&Write Tool to sponsor a contract.

Using a Merkle Tree whitelist provides a cost-efficient way to distribute NFTs to a predefined list of addresses. It ensures that only whitelisted addresses can mint the NFTs, enhancing security and efficiency. Writing a whitelist of thousands of addresses directly within a smart contract would result in significant gas costs, and additionally, due to the maximum transaction gas limit restriction, it might be impractical to update such a large whitelist in a single transaction. However, since in the Merkle Tree verification process, leaf nodes and proofs can be stored off-chain while only the root value needs to be stored on-chain, this method significantly saves on gas costs and enables whitelist setup with only one transaction.

Conflux Core Space implements a sponsorship mechanism to subsidize the usage of smart contracts. Thus, a new account with zero balance is able to call smart contracts as long as the execution is sponsored (usually by the operator of Dapps). This mechanism is designed to reduce the barrier of entry for new users.
