Products & Services

Why? Because by providing pre-built templates and complex contracts that developers can use with 0 setup we supercharge the growth of the community and the Soroban ecosystem. We have been watching closely since 2014 and even though Stellar is a solid foundation as it is with its scalability, interoperability and speed, Soroban will unlock so much more potential with Rust based smart contracts. We want to help build it. The idea is to create a library for Soroban smart contracts similar to OpenZeppelin. In contrast to OpenZeppelin it will not have ERC-20 or Proxy contracts because those are available in the core Soroban offering but it will have additional mathematical, cryptographic components and on top of that it will have a showcase of complex systems like Stake controlled governance or yield bearing instruments. Goals: Attract rust developers from existing web3 ecosystems and potentially web 2. Build a simple wizard for users to build their contract thru a pick and choose interface similar to OpenZeppelin contracts. Make it easy for all developers to onboard and build with Soroban. Build a complex stake controlled governance dao contract to showcase more advanced uses. This proposal also includes the beginning of another tool, due to lack of writing space in the form, Quasar details are attached at the bottom of the pitch deck: Quasar - A Soroban indexer - GraphQL APIs, Indexing and analytics of the Soroban ecosystem. We believe that Nebula will be a valuable tool for the Stellar community, making it easier to get started and build commercial products on top of Soroban and thus strengthening its long term ecosystem. Attached to this submission is a pitch deck, please use that one to get a comprehensive idea of the vision. Here is a list of possible smart contracts/tools to add to the SDK they have noted down on our internal update yesterday on Friday: Auction, Coin Flip, Lottery, MarketPlace, FundMe Contract, Raffle, Math (SafeMath + SafeDecimalMath), Pause Contract - Allow pausing some transactional process, Payment splitter, Reverse billing splitting, Voting facilities. Other projects in this space we could collaborate with: Tenzing Catalog - An excellent idea to showcase contracts. Different from Tenzing we will allow users to customize contracts through a no-code UI. Sorosorcerer - Another excellent tool. Different from Sorosorcerer we are not only building the UI but also adding new math/crypto modules and new complex contracts like stake controlled governance and yield bearing instruments.
