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.

  1. Managed Contract API: Deploy contracts and build transaction with a simple REST API interface
  2. 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.


Add your own contract to the Marketplace

Do you have a smart-contract and want to earn royalties for it?

To get added to the Marketplace, follow the following Contribution Instructions

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 overtime and building confidence in the community using 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

  1. Dependable Contracts: Access a curated collection of modular, robust, and reusable smart contracts. Benefit from contracts that have undergone rigorous community assessments.
  2. Standardize Contract Interface: Interact with contracts through intuitive API, SDK, or UI compoments, lowering the barrier to entry into Web3 and unlocking the power of blockchain for everyone.
  3. Instant Deployment: Avoid cumbersome and expensive Cardano backend infrastructure and seamlessly deploy contracts into your web2 application.
  4. 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.
