A "smart contract" is simply a program that runs on the Conflux Core blockchain. It's a collection of code (its functions) and data (its state) that resides at a specific address on the Conflux Core blockchain. To learn more about smart contracts, see our Introduction to Smart Contracts.
This tutorial will guide you through the steps to create, write, and deploy an ERC1155 NFT smart contract on Conflux CoreSpace using Hardhat. Additionally, it will show you how to view your contract on ConfluxScan. You can find a practical example in the Conflux-NFT-CRC1155 repository.
This tutorial guides developers on transferring any CRC20 token from Core Space to eSpace, The goal is to transfer a CRC20 token (A) issued on coreSpace to become an ERC20 token (eA) in eSpace. Currently, if there is no corresponding token in eSpace, it's not possible to use the official cross-space bridge directly.
This tutorial will guide you through the steps to create, write, and deploy an CRC721 NFT smart contract on Conflux CoreSpace using Hardhat. Additionally, it will show you how to view your contract on ConfluxScan.

ECDSA (Elliptic Curve Digital Signature Algorithm) is a widely used digital signature algorithm in blockchain and cryptocurrency. It has the following characteristics:

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 is the native space of the Conflux network. Thanks to Conflux's innovative Tree-Graph ledger structure and consensus algorithm, Core Space achieves performance far surpassing that of Bitcoin and Ethereum without sacrificing decentralization. This provides strong support for the development of the Conflux ecosystem.
