# logion Smart Contracts

Smart contracts establishing the link between your tokens and the logion network.

Currently, a single contract is provided: `Logion`. This contract links an NFT (e.g. ERC721 or ERC1155)
to a logion collection item.

## Overview

### Installation

```console
$ yarn install --dev @logion/solidity-contracts
```

### Usage

Once installed, you can use the contract in the library by importing them:

```solidity
pragma solidity ^0.8.17;

import "@openzeppelin/contracts/token/ERC1155/ERC1155.sol";
import "@logion/contracts/Logion.sol";

contract MyCollectible is ERC1155, Logion {
    constructor()
        ERC1155("https://some.domain/{id}.json")
        Logion(
            Strings.toHexString(address(this)), // The address of the contract is being used to generate a unique item ID per token
            "334801581596596632473758891935041239976", // The collection LOC ID
            "certificate.logion.network" // The domain for building a logion certificate URL
        )
    {
    }
}
```

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
