Plug-and-Play Smart Contracts
Smart-Contract Marketplace
Maestro has released Cardano's first Smart Contract Marketplace. A repository of open-source & audited smart contracts contributed by the community. This platform is a significant step toward promoting open collaboration and trust within the smart contract landscape.
In addition, Maestro offers two novel services aimed at empowering developers with the low-code/no-code tools to build and deploy secure dApps with ease.
- Managed Contract API: Deploy contracts and build transaction with a simple REST API interface
- Contract UI Widgets: Integrate whitelabel React components directly into your app

Contract Royalty
Royalties are directly encoded into the contract and automatically distributed to the contract author when executed. Just like NFT royalties, this insures the author is incentivized to open-source their contract and be rewarded accordingly while benefiting the Cardano ecosystem with standardized and vetted contracts for any one to use.
