Overview
Nucast Labs is a software studio that builds blockchain apps for other teams and publishes developer tools on GitHub. Clients hire its developers to design and build custom Cardano apps1. Developers can also pick up its public code libraries, such as a tool that lets an app pay transaction fees on behalf of its users2.
Nucast Labs is the development arm of Nucast Pte. Ltd., a company based in Singapore, and the same team runs Nucast, a video-streaming and digital ownership platform1. Sricharan Ganta, founder and CEO of Nucast, leads the Nucast Labs team3. The studio focuses on Cardano1, where its smart contracts (programs that hold and release funds by fixed rules) run. On Midnight, a privacy-focused partner chain, its off-ramp toolkit records each payout, and a signed receipt ties that record back to the funds held on Cardano4.
Key Features
- Apps that cover fees for their users. The Nucast Labs gasless library lets an app cover the network fee for its users, so a person can sign and send a transaction without holding any ADA for fees2. The sponsor publishes rules for which transactions it will cover.
- Subscription billing for Cardano apps. A Nucast Labs subscription library lets a user lock funds once and draw on them for access over time. Access runs through Hydra, a fast layer 2 side channel that settles back to the main Cardano network5.
- Cashing out ADA to everyday payment apps. The MidnightZK Off-Ramp SDK, a developer toolkit, is built to hold a user's ADA in escrow until a payout through Wise, Revolut, or Cash App is confirmed, and to return it after a deadline if the payout never happens4.
- Fair random numbers on the blockchain. An on-chain random number library, funded and completed through Project Catalyst, gives apps and smart contracts a source of random numbers that anyone can check6.
- Private trading experiments. A test-network prototype for perpetual futures, a type of trading contract with no expiry date, uses Midnight proofs to keep order price, size, and trader identity off the public record while settlement is anchored on Cardano7.
What to Expect
The Nucast Labs website is a single page. It gives a short studio description, a gallery of past projects and partner logos, links to Nucast blog posts, and a team section that names its developers, analysts, and designers1. Project inquiries go through a contact email rather than a sign-up form1.
Developers will get the most from the studio's GitHub organization, where the libraries sit with setup guides and code samples. The gasless library installs from npm, the standard package registry for JavaScript code, and ships a separate version for use inside a web browser2. The Midnight off-ramp toolkit has its own documentation site and a written account of what each layer of the system proves4.
Organizations looking for a build partner can review the studio's track record through Project Catalyst, Cardano's community grant program. The Nucast proposer profile lists each grant request and its status, including the completed gasless transaction and Hydra subscription libraries8. That record shows what the team has shipped before any conversation about a custom build starts.
