Parity's ink! is an extension of the popular Rust programming language, in this, it is an embedded domain-specific language (eDSL). It is an opinionated language developed with the focus on Smart Contracts for the Substrate framework
The smart contracts developed through ink! are compatible with the

Swanky Suite is based on existing tools like cargo contract CLI
and polkadot.js
but extends their functionality with many additional features such as smart contract templates which reduces the contract development lifecycle.
You can use Swanky to convert your pre-built solidity contracts to ink!-compatible
To begin with, install the swanky CLI tool:
With this done you can navigate to your project or start a new one. It is not needed to install swanky node for this process.
At this step you can update your code or simply use one of the preconfigured template. Once you are donem add the network you will be deploying to in swanky.config.json:
You will need a swanky account to deploy the contract
You can also test with a dev account and see the mnemonic being added to the JSON
If you have already compiled your contract using Solidity:
The main annoyance in this process is mycontract.json
which needs to be created manually for precompiled contracts. However, it appears it is expected to contain the exact same thing as the mycontract.contract
minus the wasm key.
This would also be done automatically normally, but we have to manually supply this with precompiled contracts:
Change the --network argument with the network you want to use, or use local for testing
Facing error:
check your path in the JSON is correct!
If you are facing issues with cargo, you might need to first cargo contract
alternatively, verify the , it might not be a swanky issue
