Solidity Implementation of Semantic Soulbound Token.
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.

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.
- To install Hardhat
npm install --save-dev hardhatgit clone git@github.com:JessicaChg/semanticSBT.git
cd semanticSBT
- install the library of this project depends on
npm install
- compile contracts
npx hardhat compile
- test contracts
npx hardhat test
- deploy to local
npx hardhat node
npx hardhat run scripts/deploy.js
- 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>
