Building on Dymension involves a comprehensive set of tools and features that enable developers to create and deploy application-specific RollApps efficiently. Here’s an overview of the developer’s toolkit and resources available in the Dymension ecosystem:

  1. RollApp Development Kit (RDK): The RDK is a fundamental tool for developers working with Dymension. It is a pre-packaged set of generic modules that provide common functionalities needed for blockchain development, such as account creation and token management. This kit simplifies the process of deploying a RollApp on top of the Dymension Hub.

    The Dymension RollApp Development Kit (RDK) is a comprehensive toolkit for building RollApps on the Dymension blockchain. It’s based on the Cosmos SDK and includes pre-built modules to speed up the development process. The RDK allows developers to create RollApps consisting of two core services: a client and a server. The server side is designed for custom business logic implementation alongside pre-packaged modules, while the client component, known as dymint, replaces Tendermint for block production and networking.

    Key features of the RDK include modules for token transfers, on-chain proposals, software upgrades, and the IBC bridging protocol. It also supports additional frameworks like Ethermint for EVM smart contracts and CosmWasm for Wasm framework. The RDK makes specific adjustments to the default Cosmos SDK modules, including epochs, mint, distribution, and sequencers modules, catering to the unique needs of RollApps.

    This toolkit simplifies and expedites the development and deployment process for RollApps, making it a valuable resource for developers looking to build on the Dymension blockchain​​. For more detailed information and guidance on using the RDK, you can visit the Dymension Docs.

  2. Dymension Hub: The Dymension Hub is a Cosmos SDK Proof-of-Stake chain that uses the Tendermint Core state replication model for networking and consensus. Unlike monolithic blockchains, the Dymension Hub is designed to offer optimized services for RollApps, providing them with essential features such as security, interoperability, and liquidity.

    The Dymension Hub is a crucial component of the Dymension blockchain network, designed to provide optimized services for RollApps. It operates on the Cosmos SDK and utilizes the Tendermint Core state replication model for networking and consensus. This architecture distinguishes it from monolithic blockchains, as it focuses specifically on servicing rollups. Here are some key aspects of the Dymension Hub:

    1. Decentralized Proof-of-Stake Chain: The Dymension Hub is a decentralized Delegated Proof-of-Stake blockchain, secured by the DYM token. It serves as the decentralized source of truth, security, and liquidity for the network of RollApps.

    2. Validator Participation: The Hub uses Tendermint Core, relying on a distributed set of validators responsible for committing and signing new blocks. These validators, who bond DYM tokens, play a crucial role in maintaining the integrity and security of the Dymension network. Token holders can delegate their tokens to validators, earning rewards for participating in and securing the network.

    3. RollApp Support: The Dymension Hub is built to support RollApps, which are application-specific rollups. It provides them with the necessary security, interoperability, and liquidity. RollApps interact natively with the Inter-Blockchain Communication (IBC) protocol, enabling safe message transfers within the Dymension network.

    4. RollApp Virtual Machine (RVM): The Hub features the RVM, a dispute-resolution mechanism that simulates a RollApp execution environment. This mechanism ensures deterministic outputs for transactions, supporting various execution environments.

    5. Automated Market Maker (AMM): An embedded AMM in the Dymension Hub facilitates shared liquidity and security. This AMM is essential for RollApp operations, providing a vital infrastructure component for the network.

    The Dymension Hub plays a pivotal role in the network’s functionality, offering a unique blend of scalability, security, and efficiency. It underscores Dymension’s commitment to providing a robust and versatile platform for decentralized applications and blockchain innovations​

  3. Inter-Blockchain Communication (IBC): RollApps can natively interact with the IBC protocol, which enables safe and efficient message transferring between Dymension RollApps and other blockchains in the Cosmos ecosystem. This feature is crucial for building interconnected blockchain applications.

  4. RollApp Virtual Machine (RVM): The RVM in Dymension introduces a novel dispute-resolution mechanism. It simulates the execution environment of a RollApp within the Dymension Hub, ensuring deterministic outputs and enhancing transaction security.

  5. Embedded Hub Automated Market Maker (AMM): The Dymension Hub incorporates a native AMM to facilitate liquidity for RollApps, making it an essential infrastructure component for various blockchain applications within the ecosystem.

  6. Community and Support: Developers have access to a community of peers and experts through platforms like GitHub, Discord, and Telegram, where they can find support, share ideas, and collaborate on projects.

  7. Documentation and Educational Resources: Dymension provides comprehensive documentation, which serves as an educational guide and a source for all things related to building and deploying RollApps. This resource is invaluable for both new and experienced developers in the Dymension ecosystem.

By leveraging these tools and resources, developers can create RollApps that are tailored to specific needs and functionalities, benefitting from Dymension’s scalability, security, and interoperability features. This makes Dymension an attractive platform for developing a wide range of blockchain applications, from DeFi to gaming and beyond
