We Can Build a Rapid Blockchain Solution Using Substrate Framework

We design and develop robust blockchain solutions with Substrate SDK framework. This framework is written in Rust programming language and can accelerate blockchain development by providing all foundation layers that will run your consensus, networking and application layer. As Web3 application developers, the substrate framework allows us to focus on building core business logic instead of building the blockchain foundation.

Our Substrate Development Services

Cross-chain bridges

Cross-Chain Bridges

We build robust cross-chain bridges using the Substrate framework, which has XCMP (Cross-Chain Message Passing) to facilitate the unhindered exchange of assets and information across blockchains.
Sidechain integration

Sidechain Integration

We can integrate an existing Substrate-powered relaychain or dApp to connect to other chains or Polkadot for improved interoperability.

Smart Contract Development

Using Parity’s ink! we write smart contracts on substrate-based blockchain and execute business logic on a relay chain.

dApp Development

Parachain Development

We build relay chain and parachain using Substrate framework and RUST. We understand each layer of the framework and how to use them for efficient blockchain development.
Maintenance and Support

Pallets Development

From writing a new Consensus algorithm to creating NFTs, we understand how to write new pallets in Substrate framework using RUST. Our RUST developers have hands-on experience with creating Pallets and Relay Chains.

Why Use Substrate for Development?


Flexibility with WASM

Substrate is highly flexible for constructing a new blockchain and building new business logic. Using WASM allows changes to the blockchain logic for improvement or upgradation. Even on the LIVE network.



It is an open-source framework upon which some of today’s biggest blockchain networks, including Polkadot, have been built. We believe Substrate is one of the best blockchain frameworks built for future-proof changes in blockchain development.



With Data type flexibility, the framework supports and frames system libraries, allowing high customization for building blockchains.

Why Choose LeewayHertz?

We have built over 10 solutions, including blockchain, relay chains, PoCs, dapps solutions, relay chains and even Parachains on Substrate. We understand where the substrate framework works and where it doesn’t. Our full-stack RUST developers have experience with foundational RUST and its advanced features, including traits and macros combined with WASM and Cargo.

Frequently Asked Questions

What is Substrate development?

Substrate is a blockchain framework that enables developers to easily build future-proof blockchains in the fastest and most optimized way for any use case. Substrate development equips developers with open-source software built by Substrate’s ecosystem, so developers don’t need to start from scratch. For Substrate development, you can utilize the modular framework of Substrate, which is highly customizable and flexible. As Substrate’s code is field-tested and academically researched, it helps developers build blockchains fast and efficiently.

Why opt for Substrate development?

Substrate offers all the tools for development, deployment, and debugging. With Substrate, users receive 

  • Client libraries that help to create rich user experiences. 
  • Wasm smart contract platform that helps build smart contracts using any compatible language.
  • A validator voting system, working consensus mechanism, and block finalizing algorithm
  • Rust development allows you to use all the features of a programming language. 

How does Substrate work?

The working mechanism of the Substrate framework involves three important components. You can choose any of them to start a new Substrate project: 

Substrate node
The Substrate node leads the pack when it comes to functionalities and technical freedom. It is fully runnable and comes with default implementations for all components, such as privilege access, account management, and consensus.

Substrate FRAME
This is one of the Substrate framework’s most powerful tools and contains a variety of modules that are customizable business logic and can be used for specific use cases like staking, governance and consensus. It offers a wide range of services in the runtime environment.

Substrate core
Substrate core ensures that runtime implementation can be done the way you like, provided it targets WebAssembly. Also, it must adhere to the basic rules of Substate’s block creation. This allows you to use the runtime and execute it within Substrate.

What are the core concepts of Substrate development?

Substrate stands on three core concepts: 

Runtime: It is the most integral part of Substrate implementation. It is used to make Substrate-based projects work seamlessly. The runtime describes the state of the blockchain and the rules that guide it. Substrate’s runtime is also called the state transition function.  

Consensus: Substrate provides consensus engines that help determine when state transitions should occur and how to resolve conflicts. This includes block creation, finality, and fork choice. However, you can have another consensus depending on your requirements. 

Extrinsic: Substrate block comprises a header and a wide range of extrinsics. Extrinsics are important to interact with the outside state blockchains. The information gathered from the outside is important for the internal working of Substrate. 

Why choose LeewayHertz for Substrate development services?

LeewayHertz specializes in blockchain project development using a variety of tech stacks. We have developed multiple successful Substrate projects and can provide competent assistance at any stage of your project’s development. As part of our blockchain solutions, we also handle the development of blockchain projects from scratch, allowing you to succeed in the blockchain space.
