This group of smart contracts is already deployed on the Spartan Network by the BSN Foundation or BSN-authorized third parties. They provide some of the most basic and common functions of blockchain smart contracts. Developers can directly call these smart contracts without rebuilding similar functions. Most of these smart contracts are open source. BSN official contract services are listed by default in all data center end-user portals and integrated into the data center APIs/SDKs for easy access.

This group of smart contracts is fully open source and can be downloaded, modified, and redeployed onto the BSN Spartan Network for any commercial or personal use. The BSN team has reviewed and certified these smart contracts and encourages BSN Spartan users and developers to reuse these smart contracts as they see fit. Some open-source smart contracts from BSN Official Services and BSN Beginner Contracts are also included.

This group of smart contracts is specifically designed and consolidated for beginners to learn smart contract development based on the Solidity programming language. These smart contracts contain some of the most basic and common examples, methods, and functions, such as tokens, NFT, storage, DID, Multisignature, etc. We encourage beginners to not only review the code but also modify and deploy different versions to the BSN Spartan Network to fully test and practice different business scenarios based on smart contract technologies.

In order to help developers better understand the Spartan network and smart contracts, we have collected a large number of open-source smart contract projects and verified their compatibility through actual deployment on the Spartan network. Developers can directly deploy smart contracts on the Spartan network or modify smart contracts to meet their business needs.
