Conflux Core 空间实现了代付机制，来补贴智能合约的使用。 这允许余额为零的新账户调用智能合约，前提是执行操作得到代付（通常由Dapp运营者提供）。 这个机制旨在降低新用户的入门门槛。

使用 ConfluxScan的读取/写入工具赞助合约。

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.
