Semantic Soulbound Token

Semantic Soulbound Token

Solidity Implementation of Semantic Soulbound Token.

Problem Trying to solve

For now, social identity data has no common standard, then the corresponding NFT or SBT can usually only supply a single function. In order to solve this problem, Semantic Soulbound Token take Resource Description Framework as data model for SBT metadata, that make SBT can cantain more semantic information.

How to Use

contracts/
          activity/
          core/
          interfaces/

Contract

Activity.sol : A example which use semantic Soubound Token contract to create a contract for an activity.
SemanticBaseStruct.sol : Data structure which used in Semantic Soulbound Token.
SemanticSBT.sol : Semantic Soulbound Token Contract.
ISemanticSBT.sol : Semantic Soulbound Token Interface.
ISemanticSBTMetadata.sol : Semantic Soulbound Token Metadata Interface.

prepare development environment, choose hardhat as the tool

• To install Hardhat

npm install --save-dev hardhat

Clone the Repository

git clone [email protected]:JessicaChg/semanticSBT.git
cd semanticSBT

compile the contracts

• install the library of this project depends on

npm install

• compile contracts

npx hardhat compile

• test contracts

npx hardhat test

deploy

1. deploy to local

npx hardhat node
npx hardhat run scripts/deploy.js

2. deploy to testnet, take the rinkeby as example

• fill in the parameters in hardhat.config.js

// Replace "INFURA PROJECT ID" with your INFURA project id
// Go to https://infura.io/, sign up, create a new App in its dashboard, and replace "KEY" with its key
const INFURA_PROJECT_ID = "INFURA INFURA PROJECT ID";

// Replace "PRIVATE KEY" with your account private key
// To export your private key from Metamask, open Metamask and go to Account Details > Export Private Key
// Be aware of NEVER putting real Ether into testing accounts
const PRIVATE_KEY = "PRIVATE KEY";

• deploy and verify

npx hardhat run scripts/deploy.js --network rinkeby

npx hardhat verify --contract contracts/core/Semantic.sol:Semantic  --network rinkeby <DEPLOYED_CONTRACT_ADDRESS>
