-# TypeScript Solidity Boilerplate Starter Kit
-
-A BoilerPlate Template Project To Start Solidity Development With Hardhat and Typescript.
-All you have to do is create a new repository from the template and start coding your smart contracts.
-
-## Hardhat Configuration
-
-- [Typechain](https://github.com/dethcrypto/TypeChain) plugin enabled (typescript type bindings for smart contracts)
-- [Ignition](https://hardhat.org/ignition/docs/getting-started) for contract deployment
-- Testing environment configured and operational, with test coverage
-- Prettier and eslint configured for project files and solidity smart contract
-- [Solhint](https://github.com/protofire/solhint) configured for enforcing best practices
-- Github actions workflows prepared for CI/CD
-- Prepared Smart Contract Examples, Tests, Deployments and Tasks for Common ERC Standards (ERC20, ERC721, ERC1155)
-
-Check the Hardhat documentation for more information.

-
-## Supported Networks
-
-- Hardhat Network (localhost)
-- Ethereum Mainnet
-- Ethereum Sepolia Testnet
-- Polygon Mainnet
-- Polygon Mumbai Testnet
-
-Feel free to add more networks in `hardhat.config.ts` file.
-
-## Hardhat Shorthand
-
-We recommend installing `hh autocomplete` so you can use `hh` shorthand globally.
-
-```shell
-npm i -g hardhat-shorthand
-```
-
-https://hardhat.org/guides/shorthand.html
-
-### Common Shorthand Commands
-
-- `hh compile` - to compile smart contract and generate typechain ts bindings
-- `hh test` - to run tests
-- `hh igntion` - to deploy smart contracts
-- `hh node` - to run a localhost node
-- `hh help` - to see all available commands
-- `hh TABTAB` - to use autocomplete
-
-## Usage
-
-### Setup
-
-#### 1. Install Dependencies
-
-```shell
-npm install
-```
-
-#### 2. Compile Contracts
-
-```shell
-npm run compile
-```
-
-#### 3. Environment Setup
-
-Create `.env` file and add your environment variables. You can use `.env.example` as a template.
-
-If you are going to use public network, make sure you include the right RPC provider for that network.
-
-Make sure you include either `MNEMONIC` or `PRIVATE_KEY` in your `.env` file.
-
-### Example Flow - Deploy ERC721 Token
-
-> This is an example flow to deploy an ERC721 token to a public network and interact with it.
-
-#### 1.1 Deploy BasicERC721 Contract
-
-```shell
-hh ignition deploy ignition/modules/BasicERC721Module.ts --network sepolia
-```
-
-**Verify contract**
-
-```shell
-hh ignition verify chain-11155111
-```
-
-#### 1.2 Deploy and Verify
-
-```shell
-hh ignition deploy ignition/modules/BasicERC721Module.ts --network sepolia --verify
-```
-
-#### 1.3 Deploy and Verify with Custom Parameters
-
-Look at `ignition/parameters/custom.json` to see how to adjust contract parameters
-
-```shell
-hh ignition deploy ignition/modules/BasicERC721Module.ts --network sepolia --verify --parameters ignition/parameters/custom.json
-```
-
-#### 2. Interact With Contract - Mint
-
-```shell
-hh erc721-mint \
- --contract 0x1FEB5675Be6F256c4680BE447D6C353E02e04fb9 \
- --recipient 0x73faDd7E476a9Bc2dA6D1512A528366A3E50c3cF \
- --network sepolia
-```
-
----
-
-### Testing
-
-#### Run Tests
-
-```shell
-npm run test
-```
-
-#### Run Coverage
-
-```shell
-npm run coverage
-```
-
----
-
-### Project Hygiene
-
-#### Prettier - Non Solidity Files
-
-```shell
-npm run format:check
-npm run format:write
-```
-
-#### Lint - Non Solidity Files
-
-```shell
-npm run lint:check
-npm run lint:fix
-```
-
-#### Prettier - Solidity
-
-```shell
-npm run sol:format:check
-npm run sol:format:write
-```
-
-#### Solhint - Enforcing styles and security best practices
-
-```shell
-npm run solhint
-```
