Managed Smart Contracts
Smart-Contract Marketplace
Maestro has released Cardano's first Smart Contract Marketplace, a repository of open-source and 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 low-code/no-code tools to build and deploy secure dApps easily.
- Managed Contract API: Deploy contracts and build transactions with a simple REST API interface
- Contract UI Widgets: Integrate whitelabel React components directly into your app
Check out the Marketplace here.
The Managed Smart Contract service is available on the following blockchains:

Royalties are directly encoded into the contract and automatically distributed to the contract author when executed. Like NFT royalties, this ensures the author is incentivized to open-source their contract and is rewarded accordingly, benefiting the Cardano ecosystem with standardized and vetted contracts for anyone to use.

Advantages of Open-Sourcing Contracts
- Standardization: Open-source contracts can demonstrate best practices and battle-tested protocol architectures, providing a reliable foundation for developers.
- Security: Anyone can audit open-source contracts, enhancing their security over time and building confidence in the community that uses them.
- Collaboration: Open-source work benefits from diverse contributions, which can lead to higher application efficiency and robustness.
- Composability: The ability to combine and recombine contracts encourages creative and innovative protocol development.
Unlocked Benefits for Cardano’s dApp Ecosystem
- Dependable Contracts: Access a curated collection of modular, robust, and reusable smart contracts. Benefit from contracts that have undergone rigorous community assessments.
- Standardize Contract Interface: Interact with contracts through intuitive API, SDK, or UI components, lowering the barrier to entry into Web3 and unlocking the power of blockchain for everyone.
- Instant Deployment: Avoid cumbersome and expensive Cardano backend infrastructure and seamlessly deploy contracts into your web2 application.
- Rewarding Innovation: The royalty system for both the backend and frontend developers encourages a culture of sharing and collective advancement.
Managed Contract API
Maestro's Managed Contracts API gives access to ready-to-deploy smart contracts written in Plutus and Aiken or any other Cardano smart contract frameworks. The contract API abstracts away both on-chain and off-chain script interactions. Using intuitive and developer-friendly endpoints, this fully managed contract service aims to enhance developer experience, strengthen the ecosystem, and enhance the security of Dapps on Cardano.
Direct Swap UI Widget
For those looking for an end-to-end web integration, Maestro's Contract Widgets provide a no-code option, allowing developers to add full-featured frontend components to any website. All UI widgets are made open source and can be found here:
Add your own UI Widget and charge a frontend fee
Similar to smart contract royalties, front-end developers can contribute their own UI component and charge a front-end fee to receive ongoing revenue for their work.
Linear Vesting UI Widget
This API is only included in subscriptions above the Artist tier.
