How to Build on 5ireChain — Web Assembly Smart Contract (WASM)

WebAssembly (WASM) is used in the substrate as a compilation target for the runtime. WASM offers a more versatile and flexible route to smart contract development and execution. Unlike EVM, the WASM is machine independent and compatible with a variety of machine languages.

Why WebAssembly?​

WASM is used as a binary instruction format for a stack-based virtual machine. It is created as a target to compile high-level languages, including C/C++/Rust. This also allows enabling deployment on the web for client-based applications and servers. WASM can also be used as a platform-agnostic binary format. This also means it will run similar instructions across whatever machine it operates.

Blockchains require determinacy to have reliable and transparent state transition updates across all nodes in the peer-to-peer (P2P) network without the enforcement of peers for running the same hardware. Wasm is also very fast and efficient. This efficiency and effectiveness indicate that it can also be uploaded onto the Blockchain as a blob of code. This also results in it not creating bloating while maintaining the ability to execute speeds at native levels.

The use of WASM in blockchain technology is important because it allows for more efficient and secure execution of smart contracts. WebAssembly is a faster and more efficient runtime environment than traditional virtual machines, which can lead to improved performance in terms of processing speed and cost. Additionally, because WASM is a binary instruction format, it is more difficult to reverse-engineer and tamper with, providing an additional layer of security.

Furthermore, WebAssembly also allows for more flexibility in terms of programming languages, giving developers more options to write smart contracts. This can help to attract more developers to the blockchain ecosystem, increasing the pool of developers that can work on blockchain projects and ultimately leading to a more robust and mature ecosystem.

5ireChain is compatible with both Ethereum Virtual Machine and Web Assembly Machine. This means developers can deploy smart contracts over any machine state of their choice.

Let’s start with learning how to deploy a smart contract on WASM!

Smart Contract Deployment on WASM​

To deploy a smart contract in the 5ire native chain, you can use the following steps:

1. Connect to the 5ireChain network
2. Have access to a compiled WASM smart contract. This can help to provide you with a comprehensive understanding of the necessary technical details of the smart contract within the 5ire native chain.
3. To deploy the compiled WASM smart contract, the user must have direct access to a contract ABI and its WASM file, or the user may only have a contract containing Wasm and ABI.
4. Clone this repo (https://github.com/5ire-tech/wasm-contract-deployment)
5. CD to this repo and open it in VScode run ‘npm i’

Note: This step is only relevant to people who want to deploy custom contracts.

1. Users can paste all the relevant contents of the ‘.contract’ file into abi.js. They also have the option of formatting the content through the use of the VS Code extension. (right click>format document with>prettier)
2. Change the input parameter within the WS provider in the deploy.js (Provide the endpoint for the chain that you want to connect.)

The endpoint for 5ireChain testnet- Thunder: wss://wss-wasm-testnet.5ire.network

1. Change the variable phrase within deploy.js (input the mnemonic phrase of an account that does have direct access to some gas fees.)

1. Run ‘node deploy.js.’
2. After successfully deploying the smart contract on the Blockchain, the terminal will provide you with the complete contract address.

As you build smart contracts on 5ire, dApps, and other web3 projects on 5ire we invite you to consider important challenges and problem statements that exist in the world, and leverage 5ire chain and blockchain technology to address them.
